2. The Issue or Story categories can be a single-issue (i.e. The Legionnaire Who Killed), a two-parter (i.e.) Mordru the Merciless, or a multi-part saga (i.e. the three-part Dark Man Saga, the four-part Omen Saga, the five-part Great Darkness Saga, etc.)
3. The Legionnaire can be an active member, a reservist, an honorary member, a Substitute, or a Legion Academy member. They can even be an alternate timeline member, so long as that alternate timeline is associated with that version of the Legion.
4. The eras are defined as such:

• The Silver Age encompasses any story featuring the Legion from their debut in Adventure Comics #247 in 1958 to their final Action Comics back-up story in Action Comics #392 in 1969.
• The 1970s encompasses any story featuring the Legion from their first Superboy back-up story in Superboy #172 in 1971 to their final story of the 1970s in Superboy & the Legion of Super-Heroes #258 in 1979. If necessary, we can also include the follow-up issue, #259, as part of the '70s, since it finishes the two-parter and is the issue where Superboy officially leaves. This also includes the Karate Kid mini-series, if that becomes relevant.
• Volume 2 encompasses any story featuring the Legion between The Legion of Super-Heroes (Volume 2) #259 in 1980 and #313 in July 1984. Note that it also encompasses stories published during this time that feature the Legion but aren't published in Volume 2, like Secrets of the Legion.
• Volume 3, also known as the Baxter Series, encompasses any story featuring the Legion between Legion of Super-Heroes (Volume 3) #1 in 1984 and The Legion of Super-Heroes #63 in 1989. Note that it also encompasses stories published during this time that feature the Legion but aren't published in Volume 3, like Tales from the Legion and Legionnaires 3.
• 5 Years Later encompasses any story featuring the Legion between Legion of Super-Heroes (Volume 4) #1 in 1984 and the myriad Legion Zero Hour titles in September 1994.
• The Reboot (Pre-Blight) encompasses any story published between October 1994's Legion of Super-Heroes (Volume 4) #0 and the collapse of the Legion in March 2000's Legion of Super-Heroes (Volume 4) #125 featuring a version of the Reboot Legion.
• The Reboot (Post-Blight) encompasses any story published between May 2000's Legion Lost #1 and November 2004's Teen Titans/Legion of Super-Heroes Special #1 featuring the Reboot Legion.
• The Threeboot encompasses any story between December 2004's Legion of Super-Heroes (Volume 5) #1 and March 2009's Legion of Super-Heroes (Volume 5) #50 featuring the Threeboot Legion. It's the Threeboot; no breaks; it's not complicated.
• The Retroboot Legion encompasses any story featuring the Retroboot Legion, from the Lightning Saga leading into Infinite Crisis and the New 52. The (re-)introduction of this Legion is so weird that I'm not even going to try to give issue numbers. Suffice it to say that the Retroboot Legion has arcs in Adventure Comics, Action Comics, and Justice League, along with being the Legion featured in Volumes 6 - 7.
• The Rebirth (Bendisboot) Legion speaks for itself, and exists in a six-part Volume 8, a two-part Future State story, and the five-part JSA crossover.
• The Animated Series encompasses all twenty-six episodes of the 2000s animated Legion series, along with the The Legion of Super Heroes in the 31st Century companion comic. It does NOT encompass other animated adaptations.
• As much as I enjoy other adaptations of the Legion, there just isn't enough there to include on this list. Also not included is the new series, which, in spite of a promising start, just doesn't have enough material yet.

First, I ranked every Silver Age Legion villain. Then, I ranked every 70s Legion villain. Now that I’ve finally finished the Legion’s fifty-five issue run in Volume 2, picking up with Superboy #259, it’s time to rank all the Legion villains from this time period.
Many people consider this period the Legion’s true golden age, and one story arc looms above the whole time period — the Great Darkness Saga, which changed the Legion forever, serving as a rocky first big mission for Blok and Invisible Kid II as well as a proper introduction to the mysterious White Witch. And while the early stories take a while to get into gear as they shake off the remainder of 70s stupidity, once they do, the book is must-read entertainment.
And frankly, this period has its fair share of great villains.
This ranking is based on how interesting or cool I think they are as characters, and how they serve as antagonists in the story. Before I get into the ranking, let’s establish some criteria:
Volume 2. This is a Volume 2 ranking, so the villain must appear as an antagonist to the Legion of Super-Heroes or one of its 31st century members (so no Superboy or Supergirl-exclusive villains) between their second solo issue (#260) and the final issue of Volume 2 before it became Tales from the Legion (#313). Villains who appear in other books that prominently feature Legion characters are also worth considering. Likewise we’re only considering how they’re treated as characters during this time period; we can use their prior history as context, but we’re not taking those appearances into account when it comes to the villain’s quality.
Significance. The character has to be a semi-notable antagonist within their story.
Groups. To keep things simple, certain villains will be grouped. Members of villain team, or otherwise related villains, that are not especially distinct from each other, will be grouped together for this ranking. Likewise, groups that function as a unit (like the Dark Circle) count for one spot, though their individual members might receive their own rankings.
Names. If you want to be counted, you can’t be some unnamed jewel thief or something. A name is the bare minimum.
LSH Villains Only. Still no Lex Luthor. Other than that, I’m pretty lenient with this rule.

HONORABLE MENTION: The Legion of Super-Villains (The Sun Emperor, others?)
The end of this run begins foreshadowing the takeover of Orando by the Legion of Super-Villains, but that doesn’t come to fruition yet, and the only member of the present-time group we see is Sun Emperor. It’s great foreshadowing, but since they don’t clash with the Legion directly during this time period, I won’t include them. Stay tuned for the adult LSV though; they do show up on the list.
F TIER:
No F Tier this time. I don’t think this run had a single villain who didn’t work on some level, and F Tier isn’t automatic. Good job, Paul.
D TIER:
41. The Omen & The Prophet
#307 - 309
Yep, our lowest-ranked villain pair are from a four-part saga. I’m sure the Omen and Prophet have their defenders, and the Omen has a cool design. Not to mention the visuals of the story are pretty cool. But the story just drags, and they just give you nothing to latch onto with these characters. Their origin doesn’t make sense, and unlike with Modulus, I’m not even curious about learning more.
40. Lucifer 7
Secrets of the Legion #1
Lucifer 7 is a flashback villain showing the first few Legionnaires on an early case. He’s fine and he does his job, and his Who’s Who entry says he’s secretly a robot.
39. Gurlak
#307
Gurlak is a Khundish rival of Kharlak who tries to beat up Blok and gets curb-stomped. Probably shouldn’t have even made the list, but I thought it was funny.
38. Pulsar
The Brave and the Bold #198
I’m bitter about this one. We have a reunion issue tying up the plot beats of the short-lived Karate Kid series, but it’s all tragedy. Iris is still hung up on Val, wanting so desperately for things to be like they were when he was in the 20th century. And Pulsar, who’d agreed to go straight for the sake of his family, is a villain again after his family got massacred anyway. I feel really bad for the guy, to be honest, and I wish the story had more sympathy for him. I just… Pulsar was my favorite villain from the Karate Kid mini-series, and it hurts to see this be his canonical ending.
37. Golgoth
#306
Golgoth is a gang leader who takes over Takron-Galtos in a flashback to Star Boy’s second-ever mission. He’s a fairly generic villain, but he does his job. Although I think Lucifer 7 is slightly more memorable, I think Golgoth has a bigger impact on the story, so he edges out his fellow flashback foe.
36. Zera Vultun
#283
Zera’s a scientist’s daughter Drake Burroughs has a crush on before becoming Wildfire. She tries to do away with him as revenge for her father, or something. I’m not really going to look back at the issue, sorry.
35. Doyle Brande
Secrets of the Legion #1
Doyle Brande is a character who existed for two decades and change in the comics without ever making an appearance, being the guy who hired the assassins to kill R. J. Brande. As the very first chronological Legion villain, he gets mad respect despite not yet having actually appeared.
34. Doctor Mayavale
#268
Mayavale, Mayavale, Mayavale. I know that some people love this dork, and in fairness, the weird appropriation of Hinduism and the odd design make him decently memorable. Not to mention his issue giving Dream Girl a chance to shine. And he doesn’t overstay his welcome, persisting as a strange and minor oddity in the Legion’s Rogues’ Gallery. That said, he’s too weird and dumb to put any higher.
C TIER:
33. Cosmic King & Saturn Queen
#300
The only full appearance of the Legion of Super-Villains in this run is an alternate-universe version of the group who appear in an alternate universe where Computo won by teaming up with them during the visions of issue #300. It’s an interesting timeline I wish we’d seen more of, and it opens up a bunch of questions. Since the main Legion hasn’t met any of the main three adult LSVers from their timeline, I have to imagine these are the future LSVers brought to the past by Dynamo Boy in Adventure Comics #331.
What exactly happened to them in the main timeline is somewhat mysterious; in the main issue, they’re arrested by the Science Police, but the Who’s Who entry on Saturn Queen, the three adults simply vanished from the time stream on the way to Takron-Galtos.
What do I think happened to these three? My best guess is that their interference in the past with the help of Dynamo Boy is what prevented the Adult Legion timeline from playing out in the first place, and the paradox caught up with them, erasing them from existence. Young Saturn Queen never joins the LSV, and Cosmic King does but isn’t exactly a charter member. Just a guess, though.
32. Kantuu
#266 - 267
A literal genie in a bottle, this is a good example of what happens when the 80s get their hands on an early 70s plot. Sure, this genie in a bottle is a big goofy, but it has an interesting origin connected to the Guardians of the Universe, and gives a semi-retired Bouncing Boy and Duo Damsel a chance to shine. I really like the pair as the unofficial mom and dad of the Legion, training the Legion Academy and showing up as old-timers to mentor the newbies. Plus, Kantuu’s got pretty cool visuals on his side.
31. Organus & the Organleggers
#284
This one’s goofy but in a fun way. The Legion goes to Medicus One to stop some organ thieves called the Organleggers, and it turns out they’ve got this weird absorption monster called Organus on their side. Not much to say, but a solid one-shot villain in the lead-up to the Great Darkness.
30. Aton Gissark
#260
I like the circus issue. Sue me. And the idea of a circus being used as a method of peace, and then that circus being sabotaged by its own ringmaster… it’s interesting. And Aton Gissark’s brutal death is really cool. I like this one a lot, sue me.
29. Micro Lad
#305
This is a ranking out of respect, since until the Baxter series Micro Lad is the only super-reject to re-appear, serving as the mastermind behind the plot to replace Shrinking Violet. I wish I hadn’t had the Shrinking Violet twist spoiled for me, but in fairness, they hold out on you for a good long time; it’s like a year and a half between Violet’s replacement and this reveal in real life, and like six months in-story.
Micro Lad doesn’t get a lot to do here, but I do like him as a pesky little schemer, and he’s a fun development for the ongoing Imskian separatist movement storyline.
28. Zeus & the Olympians
Annual #2
This one’s weird. So Dream Girl and company are stranded back in Ancient Greece and meet the Greek Gods, who turn out to be a company of ancient Durlans in disguise, shortly before the six-minute war that destroyed their civilization. The gods are defeated, and the heroes rescued and returned to their timeline.
Except, like… Wonder Woman exists. The Greek gods are real in DC continuity. I mean, sure, these Durlans may only have been posing as real Greek gods, but still.
In spite of this, I love how it gives us an extra peak into Durlan history, shortly after Chameleon Boy’s quest there and just before we meet Yera.
27. Molecule Master
#281
The Molecule Master has always been a cool idea for a villain whose nature as an android pawn of the Time Trapper kind of sours me on the whole notion. Still, his duel with “Reflecto” is good, even if I felt a little cheated by the Reflecto twist. Like, how hard would it have been to have given us an honest to goodness Legionnaire named Reflecto who just joins the main cast? In any case, this at least solves the mystery of who sent the first Molecule Master.
26. Starburst Bandits
#272
I like these guys. They have a neat design, a cool gimmick, and a fun status as minor recurring foes. Sure, their first story was during the 70s, but in this decade they get to be fun first opponents for Blok. And the scene where they escape prison is real cool. Good stuff.
25. Universo
#295
You know, it’s remarkable how after several great issues in the Silver Age, Universo kind of drops off the face of the Earth until the Baxter series. He has a brief, terrible story in the 70s that we all choose to ignore except for it introducing us to Dvron, and then he gets this brief flashback story that Blok and Timber Wolf watch that reveals him to be a rogue Green Lantern. Still, it’s a cool flashback, I like that Universo was a rogue Green Lantern, and Blok and Timber Wolf bonding is great stuff. I can’t rank him any higher because he only appears in flashback, but this is how you keep a big villain relevant when you’re not willing to put in the leg work of actually making a good story with him.
24. Vibrex
#267
Vibrex means more as a historical moment than as an actual character. He’s the villain of a back-up story with the power to control vibrations. But between him being designed by comics legend Steve Ditko and being the reason that flight rings exist, Vibrex is an important character in Legion history despite his limited page time.
B TIER:
23. Kharlak
#287 - 299
A good, brutal rival to Blok who leads Chameleon Boy’s mission to Khundia to disaster. He later returns in the mines or something. He’s a fine face for the Khunds, if nothing else.
22. Captain Frake
#274 - 275
A femme fatale pirate leader who seduces a brainwashed Ultra Boy. She’s certainly memorable, and it’s something of a shame she didn’t get more stories as a competitor for Phantom Girl. She’s a different sort of foe than the Legion usually fights, so I’ve gotta give her points for that.
21 Dagon the Avenger
#263 - 264
A cool costume, an interesting plan (capture the Leigonnaires’ parents), and the rare chance for Tyroc to shine. I really like Dagon, but what keeps him down is his somewhat lackluster defeat; I didn’t even really realize he’d been defeated until I did a re-read. Cool character, didn’t overstay his welcome.
20. Mordru the Merciless
#276, 291, 300
I know, I know. He’s a legendary character, the villain of both one of Jim Shooter’s best stories and Earthwar, and an iconic bit of Legion history. But for this brief period in particular, Mordru doesn’t do much. Him slowly rebuilding his power on Avalon is an interesting idea, but the Legionnaires defeat him too easily. He serves as the villain of an interesting alternate timeline where the Legionnaires lose Earthwar and become killers. But his main role in this time is to get his powers sucked out by a reawakened Darkseid. Had it been any other character to do this to Mordru, it would have been frustrating. But Darkseid is just mighty enough that I buy it.
Still, I’ll give him points for how they build up to the twist in the Avalon story, since I was not expecting Mordru to pop up there.
19. Doctor Regulus
#286
Look, far be it from me to diss Doctor Regulus. In the Silver Age I was a huge Doctor Regulus fan, and whenever he showed up in the Bronze Age he brought some villainous flare, even if I have long disliked his Power Ranger redesign. But in this era he serves kind of as a filler villain. Like, all he does is show up, give a big speech about gaining power and using science to get revenge on Sun Boy, and then go down in flames. I do love his duel with Sun Boy, though; good stuff.
18. The Time Trapper
#280 - 282, 291
The Time Trapper is sort of in the same boat as Mordru, being an iconic character who just doesn’t really do much interesting in this time period. The Trapper is involved in the convoluted end to the Reflecto plotline, but I really don’t care for that ending, and the Great Darkness Saga just ignores it and revisits the Trapper where he was at the end of the Limited Collector’s edition issue where Lightning Lad and Saturn Girl get married. There, like Mordru, he gets his powers sucked out by Darkseid.
17. Ambush Bug
DC Comics Presents #59
I mean, I know he’s kind of a Superman villain, but Ambush Bug fights the Subs in his second ever appearance, so at that point in history, he’s kind of a Subs’ main villains. I mean, if you look at the Substitute Heroes’ Rogue’s Gallery, you only get a handful of characters who have only fought the Subs — notably, Sun Woman, the Zyzans, the Plant Men, and now Ambush Bug. Not a very diverse set. Anyway, this teleporting menace makes for a fun hijinks foe for the Subs, even if I don’t love how they all become idiot parodies.
A TIER:
16. Ontiir
#301 - 303
While I don’t love that the very first Science Police Officer we meet is secretly a traitor, I do love the twist of this recurring cast member secretly being a Dark Circle operative. While it calls into question the Emerald Empress’s connection to the Circle and makes you wonder why he didn’t interfere in Earthwar, the answers could be explained with some sort of wicked alliance and Ontiir perhaps being wise to Mordru’s influence in matters.
15. Pharoxx & Hagga
#286 - 287, 309
Pharoxx and Hagga are Princess Projectra’s wicked cousin and grandmother, respectively. I’ve really grown to enjoy the Orando subplots throughout Legion History, and I’m excited for the first arc of the Baxter series to spend time there. I expect Karate Kid to have an epic moment where he defeats the main villain and gets a happily ever after. Speaking of which, Pharoxx’s escape from prison provides excellent foreshadowing for the LSV’s arrival on the medieval planet.
14. Yera
#305
Does Yera count? I mean, she infiltrated the Legion, deceived Colossal Boy in a pretty icky way, collaborated with Micro Lad… yeah, I say she counts. Still, she’s more misguided than evil, and I do love the story “Guess What’s Coming to Dinner”, especially the ending. And her storyline is iconic.
13. Persuader
#269 - 271, 300
Given how the Fatal Five have been suffering diminished returns ever since Shadow Lass’s introduction, I appreciate how the Dark Man saga shakes up the status quo by breaking up this version of the Five for good. That said, Persuader probably has the least to do during this three-parter, which is why he’s the lowest-ranked of the Five.
12. Validus
#269 - 271, 300
Remember, this is still before THE TWIST. So without consideration of THE TWIST, Validus is still a tragic monster who’s also a fun kaiju. Especially because the panel where he first shows up in #269 is so cool. I really wish that adaptations got the appeal of this character more and made him bigger.
11. Mano
#269 - 271, 300
During the early stages of the Dark Man saga, Mano gets a funny quip while fighting Colossal Boy: “The more massive their bulk, the more devastating their landing! Or something like that, I’m not a student of archaic expressions”. Between that, and Mano kind of being intimidating again, I’m willing to give him the number 3 slot among the Five.
10. The Emerald Empress
#269 - 271, #300, #302 - 303
For her solo career as an ally of Ontiir and the Dark Circle, I’m giving the Emerald Empress an edge over her allies in the Fatal Five, in spite of those bangs they give her. Plus it’s always cool to see a little more of the Emerald Eye of Ekron, and her interacting with Supergirl.
9. Lightning Lord
#300, 302
Despite only showing up for one issue (plus an alternate universe adult version in #300), Lightning Lord makes the most of his impact, in a duel with Lightning Lad that is done far better than in Brotherly Hate. Lightning Lord has such a cool design in this issue, and I love how his brotherly rivalry comes to fruition.
8. The Servants of Darkness
#289 - 294
In some sense, the Servants of Darkness are very strange, and Darkseid’s criteria for creating them doesn’t make a ton of sense. Is he trying to replicate people who mattered to him personally? Then why is there an Oan and a Talokian here, and not Mister Miracle or Granny Goodness or something? Is he going for the mightiest heroes ever? Then why would Kalibak be there, or even the Oan, but not someone like Wonder Woman or Supergirl? Is he just going for powerful entities? Then why no Controllers, and why a Talokian again? They don’t quite fit together as a group, but what they lack in cohesion they make up for in some serious menace.
Unfortunately I think the story is a little too heavy on the Servants and doesn’t do enough with the Daxamite subplot, but those are small potatoes. The Servants of Darkness make the Great Darkness Sage what it is, and them being clones of ancient entities is a great twist. And the duel between Darkseid and clone Orion is great too.
7. Grimbor the Chainsman
#277 - 280
Yeah, I know he has a few appearances during the Five Years Later era, but for me this is the definitive final bow for Grimbor. While I very much dislike the end of the Reflecto arc, I do like how he acts as an ace in the hole against Grimbor, and I have to say that this is how you make a saga out of a normally B-list villain.
S TIER:
6. Pulsar Stargrave
#273
Many people don’t like the Insaniac 5 plot. I think it definitely drags in the middle a little bit, but it has a great start with “Murder Most Foul” and a great ending with the reveal of Pulsar Stargrave. I love Stargrave’s supposed killing of Ultra Boy, and I love even more his final showdown with Brainiac 5. I know he has another brief appearance in the Substitute Heroes special, this is what I consider to be the end of this character. And the best part is that he’s a character who can really only exist in a pre-Crisis world, so I don’t think we’ll ever again get a real version of Pulsar Stargrave who’s anything like the original. Anyway, this is a great end for Disco Brainiac, and a great send-off to end Pre-Crisis Brainiac’s story.
5. The Khunds
#285, 287, 298 - 300, 307 - 310
I know that the Khunds are a pretty generic warlord group, but I like the fragile politics of Khundish peace that are present in this era, especially when the Legionnaires have to save Khundia from Omen. And I like how we get to meet some individual Khunds as well. Good stuff.
4. Tharok
#269 - 271, 300
I love the Dark Man saga. As someone whose favorite era is the Shooter Silver Age, I really like how the Dark Man saga feels like a perfect melding of Silver Age characters with Bronze Age subplots. From Tharok’s friendemy relationship with his clone to their final destruction at each other’s hands, the whole story is really fun. And I love the moment where the Legion works with the Fatal Five to charge the Dark Man.
3. Computo the Conqueror
#300, 309 - 310, Annual #1
After nearly two decades of hiatus, Computo returns in spectacular fashion by taking over the body of Danielle Foccart. The Annual where this happens and Invisible Kid manages to defeat the computer is all great stuff, and the subsequent return battle with Computo ending in the curing of Danielle Foccart is a fun little story. Glad to see my Silver Age #1 back in fighting shape.
2. The Dark Man
#269 - 271
Sure, he suffers from the Paul Levitz classic of “mysterious darkness entity with unimaginable power operating in the shadows”, but the Dark Man is a genuinely good twist point in the Legion’s story. The Fatal Five had a banger origin story that didn’t really show what they could do as villains, a great follow-up that really let them loose, and then an ongoing series of follow-ups to that with diminishing returns each time. So shaking up the status quo by disbanding the team and killing their leader with an interesting twist made for a big moment for the Legion. In a way, the Dark Man saga feels like the final death of the Silver Age and its headliner villains.
As a villain himself, the Dark Man is a creepy twist on Tharok, and I love the menace when he’s all cloaked in shadow. Oh, and I love how the story turns Blok into a hero and has that great moment where the Fatal Five and Legionnaires charge into battle together. Good stuff.
1. Darkseid
#287, 289 - 294
Sure, I can be a hater. I can say that the Great Darkness saga is somewhat unevenly paced. I can say that he has too much New Gods stuff to be a Legion villain while there’s too much Legion stuff for this to be a good ending to the New God storyline pre-Crisis. I can say that the Servants of Darkness don’t make a ton of sense, or that we don’t get enough time with the enslaved Daxamites, or that his power level is inconsistent.
But c’mon. We all knew he had to win.
The menace. The great design. The masterful foreshadowing. The Legion had very rarely interacted with any elements of the DC Universe other than Superman’s immediate supporting cast up until this point; they hadn’t even met a Green Lantern yet. And then this guy shows up.
I feel like Levitz learned all the right lessons from Earthwar, both from what worked and didn’t. He gave us good time with our main villain as the Master even before the twist, and then after the twist gave us a good double-length story to satisfy. 
His battle with Orion is epic. His fight with the Superman family is epic. His terraforming of Daxam is epic. That final scene where all the Legionnaires and Daxamites surround him, defeated, is epic. It’s simple, really, when you get down to it.
Darkseid is.
And that’s why he’s number 1.

Well, that’s my list. Agree, disagree, mixed feelings? My next ranking will be of the Baxter series (plus Tales and such) villains, and then I’ll compile it all into a master list of every villain of the original Legion (pre-FYL). Let me know who your favorite villain of the era is, and who you think I treated too harshly.

An idea crossed my mind recently, one that fascinates me to no end: what if the Legion made the opposite admissions decisions that they did in the original timeline? In short, what if, when Cosmic Boy, Saturn Girl, and Lightning Lad began recruiting, they rejected Triplicate Girl and Phantom Girl but recruited Arm-Fall-Off-Boy, Mnemonic Kid, and Fortress Boy? What would happen in a timeline where the Legion was made up entirely of rejects?
Brief rules: the Legion pretty much accepts all characters who are originally Legion rejects and rejects all characters who typically become Legionnaires. To join, you at least need some sort of power or scene, so the background applicants from Secret Origins don’t count. Got it? Got it.
That’s the ridiculous idea I seek to answer today. This is an alternate timeline; don’t take it too seriously. So let’s answer it.

Spoiler: If you get to the end, the Mess wins Earthwar.

Year One
Cosmic Boy, Saturn Girl, and Lightning Lad save R. J. Brande and found the Legion of Super-Heroes, with Cosmic Boy as their first leader.
The founders hold try-outs, bringing in Arm-Fall-Off Boy, Mnemonic Kid, and Fortress Lad as their fourth, fifth, and sixth members. Arm-Fall-Off Boy (Floyd Belkin of Lallor) is ambidextrous and able to detach his arms. Mnemonic Kid is able to remove memories but not give them back. And Fortress Lad of Fwang can turn into a large fortress.
Fortress Lad’s body becomes the model for the Legion’s headquarters, while he becomes a mobile version of the Legion HQ. The Legionnaires easily solve their first case, recovering the Quintile Crystal. They then recruit Calcu-Lad, who has the power of performing advanced math equations in his mind, as the seventh Legionnaire.
defeating Lucifer-7, all while rejecting many Legionnaires who would join the timeline in the main continuity. They have a run-in with Vidar and the Green Lanterns, managing to stop him from viewing the origin of the universe.
The year ends with seven Legionnaires.

Year Two
Cosmic Boy is re-elected Legion leader for his second term. Ultra Boy applies for membership but is beaten out by Stig Ah of Rimbor, a famous hero who can reflect energy attacks by the name of Reflecto, who joins as the Legion’s eighth member. Lester Spiffany and Storm Boy join the Legion as the ninth and tenth members, respectively. Lester Spiffany is the wealthy son of a jewelry store tycoon with no powers to speak of, while Storm Boy (Myke Chypurz of Earth) has a device he can use to control the weather.
The year ends with ten Legionnaires.

Year Three
Saturn Girl is elected leader and suspends the other Legionnaires in an attempt to stop them from dying to Zaryan, only for Lightning Lad to sacrifice his life.
A week later, Antennae Boy and Dynamo Kid join the Legion as the eleventh and twelfth Legionnaires. Antennae Boy (Khfeurb Chee Bez of Grxyor) has the power to hear and project radio signals from the past, present, and future, while Dynamo Kid has electric powers similar to Lightning Lad but uses a mechanical device to produce him. Dynamo Kid soon befriends Storm Boy, and the two trade invention ideas.
A month later, Polar Boy, Fire Lad, Chlorophyll Kid, Night Girl, Stone Boy, and Estimate Lad join the Legion as the thirteenth, fourteenth, fifteenth, sixteenth, seventeenth, and eighteenth Legionnaires.
Polar Boy (Brek Bannin of Tharr) has the inherited power to generate ice and snow. Fire Lad (Staq Mavlen of Shwar) gained the power to breathe fire from meteor fumes. Chlorophyll Kid (Ral Benem of Mardru) gained the ability to make plants grow faster — or slower — from falling into a vat of super-fertilizer. Night Girl (Lydda Jath of Kathoom) gained nighttime-dependent super-strength from her father’s formula. Stone Boy (Dag Wentim of Zwen) has the inherited power to turn to immobile stone as a sort of waking, petrified sleep. And Estimate Lad has the power of estimating numbers like weights and crowd sizes with medium accuracy.
Night Girl soon falls for Cosmic Boy, and they start dating.
The Legion races into action to fight some killer robots, and thanks to Chlorophyll Kid’s detective work, is able to discover that a mysterious race of Plant-Men are behind the attack.
More Legionnaires follow. Camera Eye and Green Boy join as the nineteenth and twentieth Legionnaires. Camera Eye has the power to replay anything he sees as a projected image using his eye. Green Boy can turn objects green.
Soon, Lightning Lad apparently returns to the dead and helps the Legion bring the Thieves’ Planet to justice. It turns out that it’s actually his crossdressing sister, but the Legion rejects her for the deception. Rainbow Girl and Jungle King join as the twenty-first and twenty-second Legionnaires. Rainbow Girl (Dori Aandraison of Xolnar) has pheromonic influence connected to the emotional spectrum, while Jungle King of Lallor has the power to control animals as long as he concentrates. Jungle King’s vengeful side and love of the extreme soon creates a romance with Mnemonic Kid, while Rainbow Girl becomes attracted to a newly humbled but still very wealthy Lester Spiffany.
However, without Mon-El on the team, the Legion never discovers a way to revive Lightning Lad. Lightning Lad is never restored to life, and remains a dead Legionnaire. The Legion soon admits Ron-Karr as the twenty-third Legionnaire. Ron-Karr of Neptune has the power to turn his body two-dimensional. He soon becomes friends with Polar Boy, Fire Lad, Chlorophyll Kid, and Stone Boy.
Alaktor also joins as an impostor, and replaces the minds of Cosmic Boy, Reflecto, and Night Girl with that of Emperor Nero, Adolf Hitler, and… probably some kind of female villain, maybe Lady Macbeth? Anyway, the Legion ousts Alaktor and swaps the minds back.
Soon, the Time Institute discovers the mysterious Iron Curtain of Time and learns of the mysterious Time Trapper behind it. Night Girl captures the operators of the Throonian Tower. and Radiation Roy joins as the twenty-fourth and twenty-fifth Legionnaires. Ran Attar is a brilliant chemist with a secret formula to make feathers as heavy as lead. Radiation Roy (Roy Travich of Earth) has the power of super-radiation and soon becomes friends with Ron-Karr, Jungle King, and Mnemonic Kid.
The year ends with twenty-three members.

Year Four
Saturn Girl is re-elected leader. The Legion recruits Spider-Girl and Double-Header as their twenty-sixth and twenty-seventh members. Spider Girl (Sussa Paka of Earth) has prehensile hair. Radiation Roy soon develops a crush on her, but she has her sights set on Reflecto. Double-Header (Frenk and Dyvud Retzun of Janus) has two bickering heads who soon become best friends with Antennae Boy.
Dr. Marden King visits the Legion, introducing them to the Heroes of Lallor.
Kid Psycho joins as the Legion’s twenty-eighth member. Kid Psycho (Gnill Opral of Hajor) is the last of his kind and can create force-fields, but every time he does so it drains his lifespan by one year.
Queen Azura of Femnaz briefly turns the female Legionnaires against the boys, only to learn how few women this timeline’s Legion has — Saturn Girl, Mnemonic Kid, Night Girl, Rainbow Girl, and Spider Girl are the whole roster.
The Legion encounters Vibrex, who hampers their flight-belts, but without Brainiac-5 or Mon-El, they’re unable to come up with an alternative, and Vibrex escapes.
The Legion soon rejects Dynamo-Boy but recruits Eyeful Ethel and The Mess as their twenty-ninth and thirtieth members. Eyeful Ethel (Ethel Lyn Niwtyn of Earth) has three hundred sixty degree vision thanks to the eyes that surround her head. The Mess (Meyer Qayd of Earth) has the power to attract dirt like Pigpin from the Peanuts.
Soon after, Animal Lad, Golden Boy, Polecat, and Tusker join the Legion as the thirty-first, thirty-second, thirty-third, and thirty-fourth members. Animal Lad (Ennis Janhson of Earth) has the power to turn people into animals and back, as well as to control animals. Golden Boy (Klint Stewirt of Earth) has the power to turn objects into gold. Polecat (Dafe Meron of Earth) is supernaturally stinky. Tusker (Horace Lafeaugh of Earth) has huge tusks growing from his face. He soon becomes best friends with Eyeful Ethel, perhaps with something more going on between the two.
Mordru attacks Earth for the first time, as with the back-up story during his first appearance. Since this Legion doesn’t have a Superboy or Mon-El, it’s Reflecto and Night Girl who work together to bind Mordru. But ultimately it’s Kid Psycho who sacrifices himself to defeat Mordru, trapping him in force-fields until he can be sealed but dying in the process.
Saturn Girl begins going on dates with Storm Boy. Dynamo Kid loses an arm battling Dxaundii. Lars Hascom hypnotizes Dynamo Boy into becoming Starfinger before adopting the mantle himself.
The year ends with thirty-two members.

Year Five
Polar Boy is elected leader. The Legion has its first battle with the Time Trapper, but Mnemonic Kid wipes the Time Trapper’s memory to trap him. No Computo this time around, nor is there a Kenz Nuhor. But the false Luck Lords do start messing with the Legionnaires, and there is a string of bad luck — perhaps Calcu-Lad loses his power to an accident involving Mnemonic Kid, and Fortress Boy and Stone Boy are trapped in their immobile forms.
Color Kid joins the Legion as its thirty-fifth member. Color Kid (Ulu Vakk) gained his powers from a science experiment and can change the color of objects.
The Legion escapes the Super-Stallag of space, but a stray bolt from Nardo gives him a third head, which we’ll call Edwyrd.
The Khunds invade and try to send Nemesis Kid in as an infiltrator, but he’s rejected along with Princess Projetra, Karate Kid, and Ferro Lad (lucky for that one).
The year ends with thirty-three members.

Year Six
Estimate Lad is elected leader, with Reflecto as his deputy. The Legion has their first battle with Universo. The Legion has their battle with the Devil’s Dozen, with Dr. Orbal returning Calcu-Lad’s brilliance and restores Fortress Boy and Stone Boy.
Of course, this is when we get to the Sun-Eater incident, and part of the story of this moment is that five random Legionnaires happen to be all that’s left to handle the group. Since the main story had Legionnaires #1, 12, 16, 23, and 24 on deck for the incident, it will be the job of Cosmic Boy, Dynamo Kid, Night Girl, Ron-Karr, and Rann Attar to defeat the Sun-Eater. That’s actually not the worst possible team, given that they could have had to use Polecat or Estimate Lad.
Since Cosmic Boy’s still on the team, they still recruit the Fatal Five to help — a great idea that will never backfire. In this timeline, Validus has electromagnetic powers of the mind. Still, we all know it’s going to take a sacrifice to save the day, and by my metric there’s one obvious, tragic choice to blow up the Sun-Eater. Night Girl sacrifices herself to save the solar system, and is remembered along with Lightning Lad and Kid Psycho as the third Legionnaire to fall.
I know it’s tragic. I know she’s a great character. But Dynamo Kid and Ron-Karr both have self-interested impulses, and Cosmic Boy hesitated to make the sacrifice in the main comic. And I don’t see Rann Attar being the type to rush to the sacrifice. It’s got to be Lydda.
The Legionnaires are captured and stalked by the Hunter on the world of Simballi, resulting in the Hunter’s death. Universo disguises himself as Kandru Boltax to take over the world, but is defeated by the Legion with the help of his son. The Legionnaires defeat the Unkillables to protect the Dominator diplomats.
Mantis Morlo begins attacking different planets and tries to blow up the Earth, only to be tricked into seeing a fake Earth by Camera Eye.
The Fatal Five return to take over Talok VIII and later Earth. Fortress Lad sacrifices himself to defeat the Five by providing an impenetrable shelter against them, and despite helping them defeat the Five, Shadow Lass is rejected from the Legion.
The United Planets builds the Legion a new headquarters, and Calcu-Lad uses the Miracle Machine to repel a Dark Circle invasion, after Estimate Lad correctly estimates the number of invaders. The Legion opens up the Legion Academy and soon fights Mordru again, who accidentally buries himself in the Earth during their fight.
The year ends with thirty-one members.

Year 7
Reflecto is elected leader with Stone Boy as his deputy.
Antennae Boy is blackmailed into giving Legion secrets to Tarik the Mute’s Legion of Super-Villains. This version is composed of Lightning Lord, Nemesis Kid, Dynamo Boy, and Hunter II. Antennae Boy clears his name and the group takes down the LSV.
The Legion defeats the Taurus Gang, eventually running into the Wanderers.
The Legionnaires hold a contest to determine the best of their number, and Polecat wins, entering into an alternate dimension and fighting the villain Kodar. Polecat has no way of surviving this, and dies fighting Kodar. He joins Lightning Lad, Kid Psycho, Night Girl, and Fortress Lad as a dead Legionnaire.
Cosmic Boy and Saturn Girl, both grieving the deaths of their partners, begin a relationship. The Legionnaires are poisoned but restored by the Miracle Machine.
Uli Algor impersonates Rainbow Girl to help her half-brother rob a vault, but the problem is deduced by Estimate Lad, who recognizes a subtle difference in weight and height in the imposter.
Eyeful Ethel is turned evil by a brief trip to Ikros but her morality is restored after her new lover Nam’Lor refuses to kill Tusker.
Double-Header is elected leader (because two heads are better than one) with Reflecto as his deputy. The Legion soon faces ruinous taxation if they have more than twenty-five members, so four Legionnaires have to resign. Lester Spiffany and Ran Attar decide to shift to reserve status due to their lack of powers, and Green Boy resigns entirely due to redundancy with Color Kid. Eyeful Ethel and Tusker decide to tie the knot as the first Legionnaires to get married. Surprisingly, nobody crashes the wedding.
The year ends with twenty-five members.

Year 8
Reflecto is elected leader, with Golden Boy as his deputy. Roxxas escapes prison and isn’t recaptured due to the Legionnaires not knowing about his past on Trom. Lightning Lord clashes with Saturn Girl, who are driven to hate each other due to their history with Lightning Lad.
Reflecto is re-elected, with Chlorophyll Kid as his deputy. Tyr captures and brainwashes Animal Lad.
The year ends with twenty-five members.

Year 9
Saturn Girl and Arm-Fall-Off Boy are kidnapped by Validus and Tharok but manage to defeat them. Arm-Fall-Off Boy wins Legion leadership, with Saturn Girl as deputy. ERG-1 is rejected from Legion membership.
Animal Lad, now with the power to turn into animals, returns and tries to kill the president following brainwashing by Tyr, who is captured by Arm-Fall-Off Boy. The Legion flights and defeats the Fatal Five a second time.
Starfinger briefly kidnaps Color Kid to harness his awesome power but is defeated by the Legion. Hunter II returns for revenge but is defeated by Stone Boy.
ERG-1 works with Infectious Lass and Porcupine Pete to defeat the first robotic Molecule Master, who briefly infiltrates the Legion. The pair join the Legion as the thirty-sixth and thirty-seventh members respectively, though ERG-1 is rejected. Infectious Lass (Drura Sehpt of Somahtur) has a gut full of every imaginable disease and can sometimes control the use of them. Porcupine Pete (Peter Dursin of Earth) has a bunch of porcupine quills that he can release at will.
Jungle King retires to join the Heroes of Lallor and Antennae Boy shifts to Reserve Status to pursue a lucrative broadcast career.
Camera Eye dies to Validus under the control of Tharok, becoming the sixth dead Legionnaire along with Lightning Lad, Kid Psycho, Night Girl, Fortress Boy, and Polecat. The Legion creates clones of their dead comrades, who only manage to survive for 48 hours.
The Legion of Super-Villains returns, with the new members of Chameleon Chief, Sun Emperor, and Legion Reject Brainiac 5, who — let’s face it — was always on the verge of villainy anyway.
The Legion sees auditions from Calorie Queen, Chameleon Kid, Esper Lass, Magno Lad, Micro Lad, and Phantom Lad, and accepts all six as the thirty-eighth, thirty-ninth, and fortieth members of the Legion. This creates a problem, since that puts them at thirty members — which means that five Legionnaires need to retire. Cosmic Boy and Saturn Girl retire to plan their wedding; Double Header decides to shift into Reserve Status as well, as do Dynamo Kid and Storm Boy.
Calorie Queen (Taryn Loy of Bismoll) can eat anything like Matter-Eater Lad but also gets super-strength from ingested calories. She’s also a brilliant political mind. Chameleon Kid (Toog Lintens of Durla) is a shape-shifting body-builder. Phantom Lad (Solon Darga of Bgtzl) has the power to become incorporeal and has a thing for cougars. Magno Lad (Kort Grezz of Braal) is an Olympian with magnetic powers. Esper Lass (Meta Ulnoor of Titan) is an arrogant telepath. And Micro Lad (Lalo Muldroon of Imsk), a fierce Imskian separatist with a wicked streak.
Two more Legionnaires join in the form of Absorbency Boy and Quake Kid, who become the forty-first and forty-second Legionnaires respectively. Absorbency Boy (Kirt Niedrigh of Earth) is a human supremacist with the power to absorb the powers of other heroes, while Quake Kid (Shanen Deyus of Earth) has the power to create earthquakes. Stepping down to make room for the new members are Mnemonic Kid, who goes to join Jungle King on Lallor, and Rainbow Girl, whose modeling career takes off.
The female Legionnaires — Infectious Lass, Calorie Queen, and Esper Lass — become instrumental in the defeat of Grimbor and Charma. Charma is sent to a women’s prison, where she unfortunately dies.
Since the Legionnaires the Time Trapper feared aren’t present, he doesn’t attack them. Pulsar Stargrave enlists the fake Time Trapper’s help, as well as that of Brainiac 5, in the defeat of a reforming Mordru.
The year ends with twenty-five Legionnaires.

Year 10
Seeking a change of pace, the Legionnaires elect Infectious Lass as leader, with the Mess as deputy.
The Legion is dispatched to defeat the trio when they try to take over Colu. In desperation, Golden Boy turns the Time Trapper into gold; Calcu-Lad outsmarts Brainiac 5; and Reflecto sends Pulsar Stargrave packing.
In the aftermath, Golden Boy is put on trial for killing the Trapper, but is ultimately found innocent, and the Legion constitution is amended to allow killing in extreme circumstances.
The Deregon incident still occurs, but this time it’s Reflecto who sacrifices himself to kill the Dark Circle operative, reflecting the bomb back into the portal. As revenge for her boyfriend’s death, Spider Girl tracks down Reflecto and strangles him to death. For the murder, Spider Girl is expelled from the Legion.
The Fatal Five return to attack Mordan, and the Legion is barely able to defeat them.
The dispute over Imskian hunting rights draws Absorbency Boy into a duel with Micro Lad. Both are wounded in the duel, and expelled from the Legion by an angry Infectious Lass.
Calcu-Lad uses his brainpower to defeat the Infinite Man. The Legionnaires attend Cosmic Boy and Saturn Girl’s long-delayed wedding, and with the Time Trapper imposter nothing but a gold statue in the HQ, the wedding is not interrupted.
The Khunds launch an assault on Earth, and the reservists — Lester Spiffany, Rann Attar, Green Boy, Eyeful Ethel, Tusker, Antennae Boy, Double Header, Dynamo Boy, Storm Boy, Rainbow Girl, Cosmic Boy, and Saturn Girl — have to defend the planet from the Khunds. In the end, the mastermind of the Earthwar is revealed to be Mordru.
Mordru cages the Legion in space, with the group unable to defeat him. Finally, with one last “Long Live the Legion”, the Mess brings his power into overdrive, summoning a colossal amount of dirt that buries both himself and Mordru. The Mess is honored in the hall of heroes as the eighth dead Legionnaire, and perhaps the greatest of them all.
With increasing pressure from the Legion, the United Planets amends the tax code, and the Legion repeals the rule against married Legionnaires. Double Header, Dynamo Boy, Storm Boy, Rainbow Girl, Cosmic Boy, and Saturn Girl rejoin the Legion full time, while Eyeful Ethel and Tusker become teachers at the Legion Academy.

The year ends with twenty-nine Legionnaires: Cosmic Boy, Saturn Girl, Arm-Fall-Off-Boy, Calcu-Lad, Storm Boy, Dynamo Kid, Polar Boy, Fire Lad, Chlorophyll Kid, Stone Boy, Estimate Lad, Rainbow Girl, Ron-Karr, Radiation Roy, Double Header, Golden Boy, Calorie Queen, Chameleon Kid, Phantom Lad, Magno Lad, Esper Lass, and Quake Kid.

This was fun! Who’s your favorite Legion reject? Do you want me to do a part 2 where I continue the story? What do you think would happen?

Well, after about a week and a half of polling the community about who the best Legion villain of each letter is, it’s time to tally up the results. Before we begin, here are our results from the X category:
Zymyr: 179
Zaryan the Conqueror: 21
Zyx: 6
Time to share some results. Before we begin, I should put in some disclaimers. First, I understand that the total number of votes a villain gets is not a perfect representation of their popularity. Villains in highly contested letters that were open for longer received more votes than villains in barely contested letters that were open for a short time. And lesser villains can benefit from an easy letter, while better Legion villains can suffer from harder letters. Also, later letters tended to get more votes thanks to increased attention to the series.
Also, I forgot to include a number of villains, so villains put in via write-ins suffered an obvious disadvantage.
Legion Villains will be broken down into eight categories: Silver Age, Bronze Age, 5 Years Later, Reboot, Threeboot, Retroboot, Rebirth, and Adaptational. The character will generally be sorted into the era in which they first came to blows with the Legion, not the era when they were created; Brainiac is a little complicated in this case, but we’ll set that aside for now.
The Winners
Twenty-six Legion Villains won their respective letters: Absorbency Boy, the Blight, Computo, the Dominators, Emerald Empress I, Captain Frake, Glorith, Hunter II, Infinite Man, Jungle King, the Khunds, Lightning Lord, Mordru, Nemesis Kid, Ontiir, Persuader, Quicksand, Roxxas, Saturn Queen, Time Trapper, Universo, Validus, the White Triangle, Xotan the Weapons Master, Yera, and Zymyr.
Shout-out to u/dafuqizzis for coming up with Xotan the Weapons Master, I had nothing for ‘X’.
Emerald Empress I was the winner with the most votes with 280 votes, while Jungle King was the winner with the fewest votes at 23. The winners averaged around 121 votes, which is what Persuader got, with a median of 104 between the White Triangle and Glorith.
Of the 26 winners, 14 were from the Silver Age, 9 from the Bronze Age, 1 from Five Years Later, and 2 from the Reboot. None of the winners were from the Threeboot, Retroboot, Rebirth, or Adaptations. Of the 26, 15 were male or male-presenting, 6 were female or female-presenting, 4 were species or organizations, and Computo was genderless.
Second Place
With X being uncontested, twenty-five Legion villains got second place in their respective letters: Alexis Luthor, Brainiac, Charma, Darkseid, Eyeful Ethel, Flare, Grimbor the Chainsman, Hagga, the Inquisitor, the Jet-Belt Bandit, Kenz Nuhor, the Luck Lords, Doctor Mayavale, Nardo, Omega, The Progenitor/The Progeny, Quanto, Doctor Regulus, the Sun-Eaters, Tharok, Uli Algor, Vibrex, Weight Wizard, Yark Althu, and Zaryan the Conqueror.
Special thanks to u/swarthmoreburke for suggesting the Jet-Belt Bandit from that imaginary story from the 60s.
Grimbor was the second-place winner with the most votes with 102 votes, while the Jet-Belt Bandit was the second-place winner with the fewest votes with only a single vote. The second-place winners averaged around 24 votes, with a median of Brainiac’s 17 votes.
Of the 25 second-place winners, 12 were from the Silver Age, 11 from the Bronze Age, 1 from the Reboot, and 1 from Adaptations. None of the second-place winners were from Five Years Later, the Threeboot, Retroboot, Rebirth, or Adaptations. Of the 25, 17 were male or male-presenting, 6 were female or female-presenting, and 2 were a species or organization.
Third Place
With J and Y having only two candidates each, twenty-three Legion villains got third place in their respective letters: Ambush Bug, Beast Boy, Calorie Queen, the Dark Circle, Evillo, Firefist, Golden Boy, Holdur, Immune, Kharlak, Leland McCauley, Micro Lad, Neutrax, Ol-Vir, Pulsar Stargrave, the Qwardians, Ron-Karr, Spider Girl, Tyr, the Unkillables, Vandar the Stone, the Worldsmith, and Zyx.
Ol-Vir was the third-place winner with the most votes with 25 votes, while Neutrax was the third-place winner with the fewest votes at 0 but a few honorable mentions. The third-place winners averaged around 8 votes, with a median of Tyr and Zyx’s 6.
Of the 23 third-place winners, 7 were from the Silver Age, 11 were from the Bronze Age, 1 was from Five Years Later, 1 was from the Reboot, 1 was from the Retroboot, and 2 were from Adaptations. Of the 23, 19 were male or male-presenting, 2 were female or female-presenting, and 2 were species or organizations.
Honorable Mentions
The candidates who got the most votes who did not make the top three in their letters include Superboy Prime with 12 votes, Starfinger I with 6 votes, and Mano with 6 votes.
The Dark Circle
Next let’s talk about how different villain teams fared on this list, starting with the Dark Circle. As an organization, the Dark Circle got 16 votes. As for its five leaders, Ontiir got the most votes with 87, and neither Norak nor Siepur received any votes at all; I’m not sure if they’re ever named in any actual stories. In any case, the Dark Circle leaders had an average vote count of 18, with a median of Grullug’s singular vote.
The Dark Circle won one first place prize with Ontiir, and got a third place prize as an organization.
The Khunds
As a group, the Khunds received 69 votes. As for its significant members, only Garlak, Kharlak, and Firefist received votes, with Firefist receiving the most votes of the group at 4.
Nevertheless, the Khunds managed to bring home a first-place prize as a group and two third-place prizes with individual members.
The Legion of Super-Rejects
The member of the Legion of Super-Rejects with the most votes was Calorie Queen, with 14 votes. The only other Super-Reject who got votes was Micro Lad at 7 votes. The Super-Rejects had an average of 3.5 votes, with a median of 0 votes.
The Legion of Super-Rejects won two third place prizes with its two most notable members.
The League of Super-Assassins
The Super-Assassin with the most votes was Lazon with 4 votes, while Mist Master and Neutrax did not receive any votes. The Super-Assassins averaged around 2 votes, which was also the median number of votes, which is what Silver Slasher and Titania had.
Ironically, the Super-Assassins’ only prize comes from 0-votes Neutrax, who got third place in the ‘N’ category.
The Legion of Super-Villains
Note that we will not be considering the Retroboot expanded LSV roster for this group, since that version includes basically every major Legion villain.
The LSV member with the most votes was Nemesis Kid, with 183 votes. Chameleon Chief, Echo, Esper Lass, Magno Lad, Mist Master, Neutrax, and Terrus all received 0 votes. The LSV averaged 34 votes, with a median of 4 votes, which is what Cosmic King, Sun Emperor, Beauty Blaze, Radiation Roy, and Lazon got.
The LSV had 5 members in first place and 6 in third place.
The Fatal Five
The Fatal Five had a very impressive showing. The Fatal Five member with the most votes was the Emerald Empress I with 280 votes. The founding member with the fewest votes was Mano, although Emerald Empress II, Caress, and Mordecai all got 0 votes. The Fatal Five averaged around 77 votes, with a median of 22.5 votes between Mano and Tharok.
The Fatal Five had 3 members in first place and 2 members in second place.

TL;DR, Silver Age and Bronze Age villains were the big winners here. Thanks for reading.

Candidates:

Zaryan the Conqueror (Class: Silver Age) is a warlord who's best known for causing the very first Legionnaire death, that being Lightning Lad. He's also (maybe) the first Legionnaire kill, since every era's Who's Who Entry makes it clear he doesn't survive the destruction of his spaceship. He's later retconned into being a Khund, which makes sense for him, and gets some points for his resume despite being fairly forgettable.

Zymyr (Class: Bronze Age) is a teleporting Legion of Super-Villains member who may or may not be of the same species as the Brain-Globes of Rambat. He later teams up with Universo.

Zyx (Class: Adaptational) is the animated series' take on Mister Mxyzptlk, doing a 31st century version of a classic Superman foe much like they did with Alexis or Drax. Zyx is a mischievous imp who later becomes a reluctant ally against a very lame adaptation of Mordru.

The Zyzans (Class: Silver Age) are an underrated favorite of mine, a class of lizard people who impersonate the Legion for mining purposes or something. They're basically a last-page reveal during the War Between the Legionnaires and the Substitute Heroes so that the Legion didn't actually go evil.

Results:

Yera (Class: Bronze Age): 52

Yark Althu: 33

Rules:

1. The character with the most upvotes wins.
2. No downvoting. Any post found to have 0 upvotes will be given two votes.
3. A character may appear on this list only once, but is eligible under multiple aliases, so long as they exist. For example, Absorbancy Boy, listed under 'A', may also be a candidate for Earth Man under 'E', so long as he did not win for 'A'.
4. The character will be listed according to their supervillain name as it is most commonly used, even if that name includes a component of their real name. For example, Roxxas's first name is Kivun, but he's usually just referred to as Roxxas, and so will be listed as 'Roxxas'.
5. Titles like 'Queen', 'King', 'Lord', 'Lady', 'Prince', 'Princess', 'Professor', 'Doctor', etc. will be excluded for naming purposes. For example, Doctor Mantis Morlo will be categorized under 'M' for Mantis, not 'D' for Doctor.
6. For characters who are most often referred to by their full names, they will be categorized by their first name, since it comes first. So the aforementioned Leland McCauley will be listed under 'L' for Leland, not 'M' for McCauley.
7. Villain organizations count individually, alongside and notable members, but villain teams do not. Villain organizations are large-scale organizations composed largely of unnamed, regular members, such as the Dark Circle, the Khunds, and the Dominators. Villain teams are composed solely of individual super-villains who can be voted individually, but not as a collective. Villain teams include the Fatal Five, the Devil's Dozen, the Taurus Gang, and the Legion of Super-Villains.
8. Anyone who has debuted in a Legion story or fought them or one of their non-Superman members in a significant way counts. While I'd caution against the selection of someone like Major Disaster, who did fight Karate Kid in his solo series, that's not a hard and fast rule and may be necessary for harder letters.
9. Feel free to give your F**k, Marry, Kills for these villains, too.

Rules:

1. The character with the most upvotes wins.
2. No downvoting. Any post found to have 0 upvotes will be given two votes.
3. A character may appear on this list only once, but is eligible under multiple aliases, so long as they exist. For example, Absorbancy Boy, listed under 'A', may also be a candidate for Earth Man under 'E', so long as he did not win for 'A'.
4. The character will be listed according to their supervillain name as it is most commonly used, even if that name includes a component of their real name. For example, Roxxas's first name is Kivun, but he's usually just referred to as Roxxas, and so will be listed as 'Roxxas'.
5. Titles like 'Queen', 'King', 'Lord', 'Lady', 'Prince', 'Princess', 'Professor', 'Doctor', etc. will be excluded for naming purposes. For example, Doctor Mantis Morlo will be categorized under 'M' for Mantis, not 'D' for Doctor.
6. For characters who are most often referred to by their full names, they will be categorized by their first name, since it comes first. So the aforementioned Leland McCauley will be listed under 'L' for Leland, not 'M' for McCauley.
7. Villain organizations count individually, alongside and notable members, but villain teams do not. Villain organizations are large-scale organizations composed largely of unnamed, regular members, such as the Dark Circle, the Khunds, and the Dominators.

Villain teams include the Fatal Five, the Devil's Dozen, the Taurus Gang, and the Legion of Super-Villains.
8. Anyone who has debuted in a Legion story or fought them or one of their non-Superman members in a significant way counts. While I'd caution against the selection of someone like Major Disaster, who did fight Karate Kid in his solo series, that's not a hard and fast rule and may be necessary for harder letters.

Look, I have no idea.

A few very minor Legion villains have real names starting with the letter 'X', but I can't find a single one with a villain name starting with the letter 'X'. You gotta help me here. I'm not even sure if I'll count up the upvotes for this letter or if I'm just going to have to pick the comment that comes closest to meeting the rules, if there is one. Maybe u/swarthmoreburke will come through for me again after suggesting the Jet-Belt Bandit for 'J'. I don't know, but I'm counting on you guys.

Anyhow...

Candidates:

Validus (Real Name: >!Garridan Ranzz!<, Class: Silver Age) is a monstrous, mysterious creature that's a rampaging kaiju with the intellect of a toddler and powerful mental lightning blasts. He's actually not evil, just extremely powerful and easily controlled by malicious forces. As it turns out in the mid-80s, he's actually >!the son of Lightning Lad and Saturn Girl, warped and sent back in time by Darkseid as revenge for the Legion halting his plans during the Great Darkness Saga.!<In the reboot, he lacks this twist of fate and is significantly weaker; and in the Threeboot he's like a nature spirit or something. Does anyone here actually care about the Threeboot?

Vibrex (Real Name: Dist Vetkoh, Class: Bronze Age) is a flashback villain notable for two reasons: being the reason the Legion switched from flight belts to flight rings, and being drawn by and named after comics legend Steve Ditko in one of his only Legion works. He has power over vibrations or something.

Vandar the Stone (Real Name: Vandar Adg/Flint? Class: Let's call it "Adaptational") is a weird one. You'd think with Vandal Savage being DC's most iconic immortal, he would have had a run-in with the Legion of Super-Heroes by now. But unlike fellow immortal Ra's al Ghul, Savage has only fought the Legion in a single, out-of-continuity story: the Star Trek crossover. There, he's Vandar the Stone, a villain in an alternate universe who's a cross between Vandal Savage and Star Trek's Flint. The Legion has to team up with the Enterprise to stop his evil plan or something; I don't know, I haven't read the mini-series, and I hear the Scooby Doo crossover is better.

Candidates:

Uli Algor (Class: Silver Age) is arguably the most notable villain from the Action Comics back-ups. The half-sister of Sunburst, she impersonates Shadow Lass with light-affecting equipment and later returns for revenge with a belt designed to turn Legionnaires' powers against them. She's ultimately defeated by Ultra-Boy not using his powers.

Universo (Real Name: Argus Oranx Vidar III, Class: Silver Age) is a mastermind hypnotist and political schemer who's typical modus operandi is to seize political power using some form of hypnosis and outlaw the Legion. He's later established to be a Green Lantern, and his son, Rond Vidar - a member of the Time Institute and an honorary Legionnaire - later assumes the role.

The Unkillables (Class: Silver Age) are a group of masked assassins sent to kill Dominator ambassadors during a Shooter-era Vietnam Allegory, but with the added twist that they're secretly brainwashed with the minds of their four historical assassin ancestors: Lee Harvey Oswald, Marcus Brutus, Cassius Longinus, and John Wilkes Booth. I'm telling you, "It was Lee Harvey Oswald the Whole Time" might be my favorite last-page Legion twist.

Candidates:

Tangleweb (Class: Reboot) was an insectoid villain who served as the Reboot Legion's first major original foe, responsible for the death of the first Kid Quantum. In my opinion he's probably the most notable Reboot-original villain after the Blight.

Tarik the Mute (Real Name: Beno Tarik, Class: Silver Age) was a disgruntled teacher who founded the Legion of Super-Villains in a teacher role. He's like the LSV's R. J. Brande or Marla Latham. He unfortunately isn't a part of later iterations of the team.

Terra-Man (Class: Adaptational) is a classic Silver Age supervillain altered to be a 41st century android created by Superman X's robot parents, sent back in time Terminator-style to kill a boy who will invent the weapons used by series villain Imperiex. While his cowboy demeanor and name are taken from the comics, this version is pretty firmly a show original creation.

Tharok (Class: Silver Age) is the cyborg mastermind who serves as the original Fatal Five's leader, having once been a common crook before the accident that made him who he is. His finest hour was probably the Dark Man saga, and unlike his other Fatal Five members, he never really got his luster back after that.

Titania (Class: Bronze Age) was a super-strong member of the League of Super-Assassins who joined the Legion of Super-Villains in Nemesis Kid's iteration.

The Time Trapper (Real Names: Who knows? Could be Rokk Krinn, Lori Morning, Clark Kent, or anybody else. The mystery is half the fun. Class: Silver Age) is both the Legion's oldest recurring foe and one of the trickiest to deal with. At his best, he makes for some fun, high-concept time travel stuff. At his worst, he's DC Editorial incarnate. In general, he's a hooded villain with power over time travel.

Tseln of Thaun (Class: Bronze Age) is a serial killer who showed up in one back-up story where the Legionnaires don't actually have to do anything to capture him and then never again.

Tusker (Real Name: Horace Lafeaugh, Class: Bronze Age) was a Legion reject who was interestingly turned away by Dynamo Boy during his takeover of the Legion, before becoming a D-list Subs villain as the partner of Eyeful Ethel and briefly joining the Justice League of Earth during the Retroboot.

Tyr (Class: Bronze Age) is a guy with a cool, sentient gun who's a warlord or something and helps fill out the LSV. He's also the leader of the LSV in the animated show, where he has a fun voice performance. He's a good, minor Legion rogue who never overstays his welcome.

Candidates:

Sadaharu (Real Name: Unon Sahaharu, Class: Bronze Age) might be better classified under 'B' as Black Dragon, but since he only assumes that title in his second appearance during the Karate Kid series and is listed under 'S' in Who's Who, we'll go with 'S'. Sadaharu was the apprentice of Karate Kid's crime boss father the Black Dragon. Eventually, he becomes Karate Kid's chief rival... until he got a new Nemesis. Although between the two Major Disaster would make a case for that first slot.

Saturn Queen (Real Name: Eve Aries, Class: Silver Age) was a member of the original adult Legion of Super-Villains and the last of the three to make her debut in the young LSV; although of the expanded Adult Legion roster, Beauty Blaze never quite made it. In the Five Years Later Era, she's forced into being Prince Evillo's wife before being rescued by and marrying Matter-Eater Lad.

Sden (Class: Bronze Age) is one of those weird Cary Bates villains, an evil alien who might be good but turns out to actually be evil, trying to get his hands on the McGuffin stone so he can be 'even more powerful than Mordru'. Comics writers: please don't use phrases like that when it comes to your one-off bad guys.

Shagrek (Class: Silver Age) is a creepy, monstress, disintegrating member of the Taurus Gang.

Siepur (Real Name: Rolind Siepur, Class: Bronze Age) was a member of the Dark Circle with an accounting background who specialized in embezzlement to fund the circle's beginning.

Silver Slasher (Real Name: Ki-Lan, Class: Bronze Age) is a member of the League of Super-Assassins with sharp blades across her body who eventually joins the Legion of Super-Villains.

Size Lad (Real Name: Aarl, Class: Silver Age) was one of the Murran infiltrators, with the power to make objects larger or smaller. Without even sharing a name with a later member or being a forerunner to a later member, he might be the least notable Legionnaire of all time - until, of course, Entropy Kid, Monster Boy, Radius Lad, and X-Raay Girl.

The Sklarian Raiders (Class: Bronze Age) are a group of somewhat sympathetic, all-female plunderers; the fact that they're all women is pleasantly included into the comics rather casually. Eventually, the raiders produced a Legionnaire in the form of Kono. After the Reboot, they came from a planet destroyed by Mordru and still included Kono, though she never joins the Legion.

Spider Girl (Real Name: Sussa Paka, Class: Silver Age) is a Legion reject with prehensile hair who later becomes one of the founding members of the Legion of Super-Villains and returns with them across most incarnations. During the Five Year Gap she gets the hots for Ultra Boy and breaks good, eventually joining the Legion of Super-Heroes as the only LSV member to genuinely join the LSH.

The Starburst Bandits (Class: Bronze Age) are some classic recurring mooks whose only real notability comes from being Blok's first villains as a new Legionnaire.

Starfinger I (Real Name: Lars Hascom, Class: Silver Age) is the teenage Legion's first costumed, recurring super-villain, and in some regards can be considered the first true member of their Rogue's Gallery; although admittedly the plainclothes Roxxas did predate him. A mad scientist, Hascom was originally the Legion's medical liason until he broke bad, becoming a master thief and later trying to clone himself using Duo Damsel's DNA during her wedding with Bouncing Boy. Eventually, he was killed by...

Starfinger II (Real Name: Char Burrane, Class: Bronze Age) was a crime boss with a protection racket and many of the original's same powers based on his super-powered ring. He was the one who took out the first Starfinger to claim his name, and is the main Starfinger in the Legion TV series. However, revenge was eventually had by the first Starfinger's brother when Starfinger II was killed by...

Starfinger III (Real Name: Molock Hascom, Class: Silver Age) technically debuted during the Silver Age as an overweight crime boss before having Persuader kill the second Starfinger after the five-year gap and took the Starfinger ring, and was portrayed there as a Kingpin-like mob boss. He was eventually killed by the Khund Legionnaires.

Starlight and Starbright (Class: Bronze Age) are the mysterious henchmen of Starfinger II with super-strength and mysterious light-based powers. They seem to have some connection to the second Starfinger's powerful ring, and follow the third Starfinger when he takes control of it.

Storm Boy (Real Name: Myke Chypurz, Class: Retroboot) is a Silver Age Legion reject with weather control abilities based on a mechanical device. In the Five Years Later era he was a short-lived Legionnaire during the Gap, but in the Retroboot, he's a wicked member of the xenophobic Justice League of Earth with genuine storm powers who's eventually taken out by the Legion of Substitute Heroes.

The Sun-Eaters (Class: Silver Age) need no introduction, but I'll give them one anyway as powerful, world-devouring creatures responsible for many Legion crises - most notably the death of Ferro Lad when he sacrificed himself to stop one. Makes a good pet; just as All Star Superman.

Sun Emperor (Real Name: Nigal Doouglous, Class: Silver Age) was a member of the expanded adult Legion of Super-Villains who goes on to become the leader of the second incarnation of the teen LSV. He's sadistic and cruel, killing for the fun of it.

Superboy-Prime (Real Name: Clark Kent, Class: Retroboot) is best known in Legion continuity for founding an expansive version of the Legion of Super-Villains during Infinite Crisis and helping defeat Darkseid's evil Legion more recently. He has a whole backstory originating in Crisis on Infinite Earths, and love him or hate him, he's pretty famous - or infamous.

Candidates:

Radiation Roy (Real Name: Roy Travich, Class: Silver Age) is a radiation-based villain and former Legion reject from the Legion of Super-Villains. He doesn't do much besides fill out the ranks of the LSV, but is one of their most consistent members.

Ra's al Ghul (Class: Reboot) is a famously immortal Green Arrow villain who tussles with the Legion during the Reboot after impersonating Leland McCauley. He's very much a different hero's villain made an antagonist to the Legion, but it's a natural fit.

Also, my bad, Ra's al Ghul isn't a Green Arrow villain, he's a Superman villain.

Doctor Regulus (Real Name: Zaxton Regulus, Class: Silver Age) is a monologuing, over-the-top masked super-villain who serves primarily as a rival to Sun Boy, coming back again and again throughout the original continuity and also appearing in the Reboot.

The Resource Raiders (Class: Bronze Age) are basically just mooks for the Legion to fight in the build-up to Earthwar, led by a giant sentient brain. They end up being puppets of the Khunds, who are in turn puppets of the Dark Circle, who are in turn puppets of the real villain.

Rogarth (Real Name: Clave Rogarth, Class: Silver Age) is a member of the Taurus Gang with Kryptonian-level super-strength. That's pretty much it.

Ron-Karr (Class: Silver Age) is a sympathetic member of the Legion of Super-Villains with the power to turn flat, debuting as a Legion reject only a year before the release of the book Flat Stanley. He takes a heroic turn during the Five Year Gap as a member of the resistance force against the Dominators, and makes a similar heroic pivot in the Animated Series, where he's a Chameleon Boy-like shapeshifter.

Roxxas (Real Name: Kivun Roxxas, Class: Silver Age) is the space-pirate who massacred Element Lad's people, and an iconic villain used sparingly enough to be great as a shockingly dark Silver Age villain, the engine for a complex Bronze Age character piece, and as the first main villain of the Five Years Later era.

R'Xalim (Class: Bronze Age) is a doctor at Medicus One who treats Brainiac 5 and Matter-Eater Lad during their temporary insanity before turning bad and becoming a one-shot villain.

Quanto (Class: Silver Age) is the most sympathetic member of the Taurus Gang, with the power to turn into a beam of pure light and bounce around at super-speed.

Quicksand (Real Name: Anjelika Dugensa, Class: Bronze Age) was Pulsar Stargrave's female assistant with the powers to generate pools of sinking quicksand. She and Holdur were largely created to fill out a classic Luthor-Tessmacher-Otis dynamic with Stargrave that was so popular at the time. What became of her precisely is unknown, but her Who's Who entry reveals her to be an assassin who tried to take out Stargrave before becoming his assistant. After the battle with Stargrave on Colu, she and Holdur vanished off-world and went into hiding. She later briefly appears as Holdur's partner in the reboot. (Insert user comments about missed potential here.)

Results:

Persuader: 121

The Progenitor/The Progeny: 31

Pulsar Stargrave: 14

Phantom Lad: 6

Also shout-out to u/THEVrilDox, who chose to f**k Pulsar (presumably Stargrave, for his fashion sense), marry Psycho-Warrior (because they can purportedly fix him), and kill Prophet because he's so whiney.

Rules:

1. The character with the most upvotes wins.
2. No downvoting. Any post found to have 0 upvotes will be given two votes.
3. A character may appear on this list only once, but is eligible under multiple aliases, so long as they exist. For example, Absorbancy Boy, listed under 'A', may also be a candidate for Earth Man under 'E', so long as he did not win for 'A'.
4. The character will be listed according to their supervillain name as it is most commonly used, even if that name includes a component of their real name. For example, Roxxas's first name is Kivun, but he's usually just referred to as Roxxas, and so will be listed as 'Roxxas'.
5. Titles like 'Queen', 'King', 'Lord', 'Lady', 'Prince', 'Princess', 'Professor', 'Doctor', etc. will be excluded for naming purposes. For example, Doctor Mantis Morlo will be categorized under 'M' for Mantis, not 'D' for Doctor.
6. For characters who are most often referred to by their full names, they will be categorized by their first name, since it comes first. So the aforementioned Leland McCauley will be listed under 'L' for Leland, not 'M' for McCauley.
7. Villain organizations count individually, alongside and notable members, but villain teams do not. Villain organizations are large-scale organizations composed largely of unnamed, regular members, such as the Dark Circle, the Khunds, and the Dominators. Villain teams are composed solely of individual super-villains who can be voted individually, but not as a collective. Villain teams include the Fatal Five, the Devil's Dozen, the Taurus Gang, and the Legion of Super-Villains.
8. Anyone who has debuted in a Legion story or fought them or one of their non-Superman members in a significant way counts. While I'd caution against the selection of someone like Major Disaster, who did fight Karate Kid in his solo series, that's not a hard and fast rule and may be necessary for harder letters.
9. Feel free to give your F**k, Marry, Kills for these villains, too.

Candidates:

Persuader (Real Name: Nyeun Chun Ti, Class: Silver Age) needs no introduction, a founding member of the Fatal Five and the closest thing the Five has to a normal human, a gangland enforcer with a powerful Atomic Axe that's supposedly a remnant from the sixth World War. He's also the only major Legion villain to appear in live action thanks to Smallville. (My prediction is that he'll get the most votes)

Phantom Lad (Real Name: Solon Darga, Class: Bronze Age) is a member of the Legion of Super-Rejects and is easily the most forgettable member of the group; only he and Chameleon Kid never appeared again. He didn't have any real advantages over Phantom Girl either; he just thought he was stronger. (I don't see how even the Super-Reject fans can love this guy.)

Pharoxx (Class: Bronze Age) was Princess Projectra's jealous cousin who seized the throne in combat and tried to kill the Legion. Later, he aided the Legion of Super-Villains in their attack on Orando, only for them to interrogate and kill them. (Both the build-up to the Great Darkness and the Baxter Era are beloved, so I expect a fair showing for the Prince of Orando.)

The Progenitor (Real Name: >!Jan Arrah!<, Class: Reboot) will be sharing a spot with his creations, the Progeny, since they both start with the same letter and act as one villainous force. They serve as antagonists for the Legion during the Legion Lost mini-series, resulting in the reveal that the so-called Progenitor is >!an insane, immortal Element Lad who kills Monstress. !<(I imagine I'll get a few reboot-heads who pick these guys, since the Blight was so successful.)

Prophet (Real Name: Father Sven Kalikos, Class: Bronze Age) is part of the Omen-Prophet storyline I've given up trying to make heads or tails of.

The Psycho-Warrior (Real Name: Rejik Thomak, Class: Bronze Age) is a tech-based villain who preys on fears, like a really lame version of Scarecrow. The only thing notable about him is that he revealed the exact dates and causes of the Kents' deaths, leading to Superboy's departure from the Legion in 1980.

Pulsar Stargrave (Real Name: Vril Dox, Class: Bronze Age) is what's left of Brainiac in the 31st century, reborn in the heart of a star, who menaces his descendant and frames Ultra Boy for murder. In various iterations he's been brought to the modern times and has only been associated with Brainiac, at one point serving as an assistant for Larfleeze the Orange Lantern. (A good competitor for Persuader's lot. Insert talk of missed potential here.)

Pulsar (Real Name: Benjamin Day, Class: Bronze Age) is one of only two Karate Kid mini-series villains that deserves a mention, since Commander Blud, Master Hand, and the Gyro-Master are simply awful, and he literally just borrowed Major Disaster from other comics. A former assassin forced back into a life of crime when his family is threatened, he eventually finds himself working with Karate Kid when the tables turn. I'll always have a soft spot for him; I think that the Karate Kid mini-series is over-hated. Still, nobody's going to vote for this guy.

Sorry for taking so long for this letter.

Candidates:

Ol-Vir (Class: Bronze Age) was a Daxamite enslaved by Darkseid who stayed loyal to his Apokoliptian master. Ultimately he went for revenge along with the Legion of Super-Villains before eventually being destroyed by Darkseid when he was no longer useful.

Omega (Class: Bronze Age) was a creation of the Miracle Machine created by Brainiac 5 in a madness caused by Pulsar Stargrave who destroyed the second Legion clubhouse. Thankfully Matter-Eater Lad has guys like him for breakfast, and that's more literal than you'd think.

Omen (Class: Bronze Age) is... kind of incomprehensible. I haven't actually read the story where he appears, but something tells me that he wouldn't be much easier to understand even if I had read that story.

Ontiir (Class: Bronze Age) was a reptilian slow-burn villain introduced in Earthwar as a Science Police Officer, only to be revealed as a pivotal agent of the Dark Circle.

Organus (Class: Bronze Age) attacks Medicus One in an early 80s story during the build-up to the Great Darkness Saga. He absorbs energy and is probably someone's favorite because he's one of the first villains defeated by Blok.

Slim pickings.

Results:

Nemesis Kid: 210

Nardo: 3

Candidates:

Nemesis Kid (Real Name: Hart Druiter, Class: Silver Age) was a Legion imposter on behalf of the Khunds who was revealed, leading to a life of crime as a founding member of the Legion of Super-Villains. During his career, he appeared with each iteration of the present-day LSV, briefly fought Karate Kid solo in the past, and was ultimately the one to kill Val on Orando before Princess Projectra shows him how much of a head-turner she can really be.

Neutrax (Real Name: Wi Kan Muur, Class: Bronze Age) is a half-Professor X, half-Cyclops member of the League of Super-Assassins with the power to shoot a beat of energy that neutralizes powers and sits in a floating chair. He later joins the Legion of Super-Villains.

Norak (Real Name: Norak Kun, Class: Bronze Age) is a Naltorian genetic surgeon and one of the five founders of the Dark Circle who I believe is only named in the Who's Who articles.

Candidates:

Alright, time to describe a dozen Glup Shitto Lads (characters nobody cares about except that one commenter whose first Legion story had them as the villain) only for basically everybody to vote for Mano or Mordru.

Magnetic Kid I (Real Name: Xaxan, Class: Silver Age) was a Murran infiltrator with the power to magnetically control organic life-forms. The only things this guy really does is be hard to talk about thanks to Pol taking the name later on.

Magno Lad (Real Name: Kort Grezz, Class: Bronze Age) is a Braalian magnetic-controller who was one of the Legion of Super-Rejects before joining the Legion of Super-Villains.

Magpie (Real Name: Merg Gaterra, Class: Bronze Age) is a master thief (implied to be a rival of Benn Pares) who tried to steal a time chip from the Legion during a Bronze Age story.

Mano (Class: Silver Age) is a member of the Fatal Five who destroyed his own world with his touch of death. After that fantastic introductory feat, he then proceeds to never lay a hand on a Legionnaire, except when he's accidentally set his hand to only burn them for some reason. Since then, he's popped up every time the Fatal Five has until the Dark Man Saga, after which he failed to get into the new Fatal Five. Eventually he works for Starfinger III during Five Years Later, and becomes more sympathetic during the Reboot.

Doctor Mantis Morlo (Class: Silver Age) is a fun recurring bad guy who created an army of Chemoids to take over Orando, and then returns building muck monster in the sewer in the aftermath of Earthwar. He also shows up in the Reboot for an issue. My favorite moment is in his original two-parter, where he's about to blow up the Earth with a death ray, but first has to paint a big red target on the Earth to that he knows where to aim his death ray.

Doctor Mar Londo (Class: Adaptational) is in the comics but is only a villain in the animated series. Combining aspects of both Tyr and Mantis Morlo from the comics, Mar Londo experiments on his own son, creating Timber Wolf, and creates an army of Chemoid-like Bio Golems, eventually framing Timber Wolf for his own murder.

Doctor Mayavale (Class: Bronze Age) is a weird monk who has an obsession with karmic balance after reincarnation, and turns to evil, and has six synthetic arms... honestly, he's one of those weird Bronze Age concepts that most people blame the Silver Age for.

Lady Memory (Class: Bronze Age) was a priestess of the mountain people of Talok VIII who sought to overthrow the civilized parts of Talok VIII, ultimately facing off against Shadow Lass. She was later redeemed, marrying Shadow Lass's brother.

Micro Lad (Real Name: Lalo Muldroon, Class: Bronze Age) was an Imskian nationalist who joined up with the Legion of Super-Rejects, masterminded the replacement of Shrinking Violet by Yera, and ultimately joined the Legion of Super-Villains. He's got quite a resume for a relatively weak villain.

Mist Master (Real Name: Yer Sti-Tuan, Class: Silver Age) is a member of the League of Super-Assassins who can turn into any gas. He later joins the Legion of Super-Villains.

Modulus (Class: Silver Age) is a strange being with the power of a living planet, called Modo, who chooses to use his immense powers to be a drug dealer.

Molecule Master (Class: Bronze Age) is one of those characters that was put into the story to fulfill an Adult Legion prophecy as the one who killed Reflecto. Long story short, he was an android who tried to steal the Miracle Machine and was later revealed to be a pawn of the Time Trapper.

Mordru the Merciless (Class: Silver Age) is a master of black magic with control over Zerox. One of the most powerful beings in the universe and at times the Legion's deadliest foe (competing only with the likes of Darkseid, the Time Trapper, Glorith, the Infinite Man, and almost Pulsar Stargrave), he is responsible for one of Jim Shooter's best two-parters, masterminded Earthwar, and also was responsible for some annoying stories in the early 70s. Nowadays he's often considered a Doctor Fate villain or something, but real ones know that he's a Legion foe through and through.

Mystelor (Real Name: Zera Oliet, Class: Silver Age) was a Titanian telepath and the only female member of the Taurus Gang. She was frequently hit on by Shagrek but had feelings for Quanto, and was eventually impersonated by Dream Girl. Eventually she reformed and got with Quanto. Good for her.
