The negelected and least viable competitive pesudo-legendary introduced in Kalos doesn't get a Mega Evolution despite being introduced in the same generation with high stats but not good distributed.

Mega Goodra X remains pure Dragon, Dragon's Maw ability, +50 Attack and Speed, -40 Special Attack in exchange of +40 Defense.

While Mega Goodra Y is Dragon/Water, Shed Skin, -50 Attack and -50 Speed, +100 Defense, +50 Special Attack and +50 Special Attack.

Pokedex Entry for Mega Galvantula:

"Mega Galvantula carries a battery-shaped weapon on its back just by eating electricity that are more common around urban cities that ended up casuing a power cut."

The the fact Galvantula is based on hairy spiders and making electric webs inspired by electric fences which explains why Galvantula has the type combination of Bug/Electric. The Mega Evolution now includes a weapon shaped like a battery that allows it fire electric bursts onto the targets. Galventula is a great Pokemon with good stats, types, abilities and strong moves perfect for casual play.

Galvantula's two strongest stats are its Speed and Special Attack so adding 45 and 55 to Speed and Special Attack respectivly when going through Mega Evolution, Mega Galvantula has base 153 Speed and base 152 Special Attack, its ability its Sheer Force since both Thunderbolt and Bug Buzz that match Galvantula's typing and make use of its Special Attack can hit harder with Sheer Force revoming those secondary effects, also its coverage more: Energy Ball hits harder.

This is a fan-made Mega Evolution for an offical Pokemon, Pokemon is owned by Ninendo and Game Freak, fanart is owned by me.

Hydreigon is one of the Powerhouse Pokemon that lacks a Mega Evolution, there are three others of the same category that don't have Mega Evolution either. So I'm giving it Dragonize as an ability that turns Normal-type moves into Dragon-type moves with 20% increase boost, 30 points add to its Attack, 10 to Special Attack, 20 points added to Defense, Special Defense and Speed.

Pokedex Entry for Mega Beeheeyem:

"The result of Mega Evolution has caused Beheeyem to control it's victims brain and memories with now 5 different coloured fingers (purple, green, red, yellow and blue). Its psychic powers have been expanded to make certain Pokemon disappear. When it covers the area with a terrain of psychic, opponents fear they might have their memories edited."

I'm doing Mega Beheeyem is because I'd like to make Mega Evolution to ensure every Pokemon from each generation gets at least one type represented by a Mega Evolution, since there are no offical Mega Evolutions introduced in Generation 5 that are Psychic type which is the whole purpose why I'm making them so all generations that have at least one Pokemon of all types get a Mega Evolution like making Mega Jynx because no Gen 1 Pokemon Ice-type can Mega Evolution at the moment.

I've given Mega Beheeyem the ability "Psychic Surge" which goes in line with the lore of modifying the opponent's memory, beside I want to give Mega Pokemon different abilities that see little to no distribution. Mega Beheeyem gets 40 points increase to Defense, allowing it to take more physical hits, +40 points to Special Attack that hits opponents with a super powerful Expanding Force as it learnt the move from Isle of Armor. The final 20 points will be added to its Special Defense equal to its Defense.

Pokedex Entry for Mega Beheeyem:

Mega Evolution unlocks Beheeyem’s full extraterrestrial intellect. Its brain operates like a supercomputer, processing countless thoughts at once. The psychic field it generates is so intense that even machines begin to malfunction in its presence.

Beheeyem’s biggest flaws in its vanilla form boil down to three things: terrible Speed, only average bulk, and being completely outclassed by other slow Psychic‑types. These issues are consistently highlighted across competitive analyses, and they explain why Beheeyem rarely succeeds outside of niche Trick Room teams.

Used saved memory beheeyem Identify flaws of vanilla version

Beheeyem’s biggest flaws in its vanilla form boil down to three things: terrible Speed, only average bulk, and being completely outclassed by other slow Psychic‑types. These issues are consistently highlighted across competitive analyses, and they explain why Beheeyem rarely succeeds outside of niche Trick Room teams.

🧠 Core Flaws of Vanilla Beheeyem (Grounded in Sources)

1. Terrible Speed (Base 40)

Beheeyem is slow even by Trick Room standards.

• It often takes a hit before moving, even when trying to set Trick Room.
• Under Trick Room, several common Pokémon are still slower, meaning Beheeyem gets outsped even in its own preferred environment.

This makes its signature strategy unreliable.

2. Only Average Bulk (75/75/95)

Its defenses are not high enough to compensate for its Speed.

• It struggles to survive strong neutral hits.
• Weaknesses to U‑turn, Knock Off, Dark, Ghost, and Bug moves make it easy prey for common attackers.

This limits its ability to set up Trick Room or Nasty Plot safely.

3. Poor Defensive Typing (Pure Psychic)

Pure Psychic offers:

• Few useful resistances (only Fighting and Psychic)
• Many common weaknesses (Dark, Ghost, Bug)

This typing is especially bad in metagames filled with Dark‑type priority like Sucker Punch.

4. Outclassed in Every Role

Beheeyem competes with multiple slow Psychic‑types who simply do its job better:

• Reuniclus — far bulkier, better abilities
• Musharna — much bulkier, more reliable setup
• Slowbro / Slowking — superior typing, bulk, and utility

Even as a Trick Room sweeper, it loses to:

• Wishiwashi (better bulk + power)
• Alolan Exeggutor (better coverage + Trick Room access)

Beheeyem rarely has a reason to be chosen over these.

5. Struggles to Set Up

Even though it has:

• Trick Room
• Nasty Plot
• Recover

…it often cannot find safe turns to use them due to its bulk and typing.

6. Psychic STAB Is Easy to Wall

Psychic is a mediocre offensive type in tiers filled with:

• Dark‑types
• Steel‑types
• Bulky Ghost‑types

This forces Beheeyem to rely heavily on coverage.

7. Competition for Analytic

Analytic is strong, but Beheeyem’s Speed means it often gets KO’d before it can take advantage of the boost.

📉 Summary: Why Vanilla Beheeyem Fails

• Too slow to function outside Trick Room
• Not slow enough to dominate inside Trick Room
• Too frail to set up
• Too many weaknesses
• Too much competition from better Psychic‑types
• Psychic typing is a liability
• Coverage and utility aren’t enough to save it

Beheeyem is a classic case of a Pokémon with great Special Attack but no reliable way to use it.

If you want, I can now:

• Identify its design philosophy flaws
• Brainstorm buffs (stats, moves, abilities)
• Create custom abilities specifically for Beheeyem
• Design a Mega Evolution or regional form
• Compare buff ideas to existing abilities to ensure balance

Which direction do you want to take Beheeyem next?

Optional Mega Evolution, +40 Defense, +40 Special Attack, +20 Special Defense, same type, psychic surge

Mega Beheeyem with +40 Def, +40 SpA, +20 SpD, Psychic typing, and Psychic Surge is a massive power spike — but surprisingly, it’s still balanced if designed carefully.
Here’s the full breakdown, tailored to your competitive‑analysis style and your interest in buffing flawed Pokémon.

⭐ Mega Beheeyem — Final Statline

Base stats (vanilla):

• HP 75
• Atk 75
• Def 75
• SpA 125
• SpD 95
• Spe 40

Mega stats (+40 Def, +40 SpA, +20 SpD):

• HP 75
• Atk 75
• Def 115
• SpA 165
• SpD 115
• Spe 40

BST: 585 (up from 485)

This is a huge improvement, but not absurd — still below many Megas.

🔮 Ability: Psychic Surge

This is the real game‑changer.

What Psychic Surge fixes:

• Beheeyem’s biggest flaw: getting revenge‑killed by priority Terrain blocks Sucker Punch, Shadow Sneak, First Impression, etc.
• It gives Beheeyem immediate offensive pressure without needing setup.
• Terrain‑boosted Psychic turns its 165 SpA into nuclear levels.

What Psychic Surge doesn’t fix:

• Speed (still 40)
• Being forced into Trick Room or bulky offense
• Dark‑type matchups
• U‑turn weakness

So it’s powerful, but not unstoppable.

📊 Damage Benchmarks (Terrain + 165 SpA)

These numbers show how hard Mega Beheeyem hits:

• Terrain‑boosted Psychic OHKOs most neutral targets
• 2HKOs even bulky Steels with coverage
• Dark‑types still wall it, forcing coverage reliance

It becomes a top‑tier wallbreaker, but not a sweeper.

🧠 Role Shift: What Mega Beheeyem Becomes

1. Terrain Wallbreaker

Comparable to:

• Tapu Lele (but slower, bulkier, and weaker coverage)
• Mega Alakazam (but slower and bulkier)

It becomes a slow Lele with better bulk and worse Speed.

2. Trick Room Abuser

Under Trick Room:

• Outspeeds everything
• Terrain‑boosted Psychic becomes absurd
• Bulk lets it set Trick Room itself if needed

This is its strongest mode.

3. Bulky Psychic Pivot

115/115 bulk is respectable.
It can run:

• Recover
• Calm Mind
• Trick Room
• Nasty Plot
• Analytic‑style punishing hits (via low Speed)

Terrain gives it the immediate pressure it always lacked.

⚖️ Balance Check — Is This Broken?

Surprisingly, no.

Why it’s not broken:

• Speed is still awful
• Dark‑types still shut it down
• U‑turn still chunks it
• Terrain lasts only 5 turns
• Psychic is easy to resist
• No priority of its own
• No defensive typing improvement
• No new coverage added

It becomes strong, but not oppressive.

Comparable Megas:

• Mega Camerupt (slow Trick Room nuke)
• Mega Slowbro (bulky Psychic tank)
• Mega Alakazam (fast Psychic nuke)
• Tapu Lele (terrain Psychic nuke)

Mega Beheeyem sits somewhere between Camerupt and Lele.

🧩 Summary: What Your Mega Fixes

• Bulk → finally survives neutral hits
• Power → 165 SpA + terrain is monstrous
• Priority weakness → terrain blocks it
• Setup reliability → bulk lets it use Trick Room or Calm Mind
• Outclassing issue → now has a unique niche (slow terrain wallbreaker)

What it still struggles with:

• Speed
• Dark‑types
• U‑turn
• Steel‑types without coverage
• Terrain dependency

This is a clean, elegant buff that respects Beheeyem’s identity.

Core takeaway: Mega Samurott becomes a brutal warlord‑tier attacker with Supreme Overlord, massive stat boosts, and lore that reframes it as the final evolution of Unovan samurai tradition—an emperor of the battlefield whose horn and armor are living relics of ancient wars.

Pokédex Entry — Mega Samurott
When Samurott Mega Evolves, the spirit of every warrior who once trained alongside its ancestors awakens within its armor. Its crimson horn is said to contain the memories of countless battles, guiding its strikes with supernatural precision. Mega Samurott commands the battlefield like a supreme warlord, empowering its allies and striking fear into its foes. The more fallen comrades it fights for, the stronger its resolve becomes.

Legends claim that Mega Samurott once led entire armies of Water‑type Pokémon, carving its name into Unovan history as the “Tide Emperor.” Its roar can be heard across oceans, and its presence alone can turn the tide of war.

Changing Mega Samurott to Water/Fighting doesn’t just make sense—it perfectly aligns with its samurai identity. This typing elevates its lore, its battlefield role, and its thematic connection to Supreme Overlord. Now it becomes a true warlord of the sea, a martial emperor whose blade and discipline define the tide of battle.

+40 Attack and Speed and +20 Special Attack,

I'm gonna do Unova Mega Evolutions starting with Beartic, categorised as the Tundra Pokemon after evolving Cubchoo at level 33, it's a pure Ice-type with three ability options: Snow Cloak, Slush Rush and Swift Swim. It's a Pokemon based on a polar bear though with a cartoon-like twist like ice spikes formed from the lower jaw. I've made a Mega Evolution with a massive makeover, first extra layers of fur are now formed from its shoulders with a blueish tint and its arms to make it look like it gained muscles, next four more ice spikes have been generated from its lower jaw, and finally four-pack torso appear in a blue gray colour which resulting in its endless swimming.

Pokedex Entry for Mega Beartic:

"It's known that Beatic is given a new nickname after Mega Evolution, it's been called the Winter Atrocity known for its predatory hunting skills during the northern lands that it's a feared enemy for that uses it's frosty claws and breezing breath to destroy its prey.

Mega Beartic keeps one of its three ability options from the base form, Slush Rush as Mega Swampert has Swift Swim so a Mega Pokemon with an ability that doubles its Speed with a different weather. Slush Rush doubles the user's Speed during snow as Swift Swim is for rain. Mega Beartic gets Water as a secondary typing that gives it STAB (Same-type Attack Bonua) on Aqua Jet and Liquidation to deal more damage against Fire-types that resist Ice-type moves and Rock types because Ice is weak to Rock type moves. Mega Beartic gets +40 point increase to Speed to enable to outrun enemies during snow, +20 to its remaining stats that matter being Attack, Defense and Speed. The extra Attack means Mega Beartic will deal more damage, the extra defenses to ensure Beartic has good endurance despite its type combination resisting two types and weak to four.

Finally I've covered 10 Pokemon from Generation 4 to make new Mega Evolution designs and the final Gen 4 is the last member of the Sinnoh starter trio, Infernape which means all Sinnoh starters are finally cleared so I can easily move on to Generation 5, taking place at the Unova region where this introduced the most amount of Pokemon of any generation by far with 156 introduced.

Pokedex Entry for Mega Infernape:

"The result of Mega Evolution has rewarded Infernape to improvise a new fighting stance called Monkey Fu which is made of pyrokinetic martial arts Infernape practises both physically and mentally."

Infernape still has good stats to be a mixed attacker making it very unpredictable compared to more min-maxed Pokemon so it retains the archetype in its Mega Form, Blaziken and Emboar both access Mega Evolutions and share the same type combination Fire/Fighting both hit hard on the Physical side. Infernape gets +35 boost to both Attack and Speed and +30 to Speed, Mega Infernape is given the ability No Guard allowing guaranteed Focus Blast and Fire Blast hits and it doesn't mind being hit with Hydro Pump and Hurricane because Infernape is meant to hit hard and fast and wished we had better mixed attackers in general.

Mega Empoleon makes it debut as part of my Mega Evolution fanart project which is Mega Evolutions for Pokemon that don't have one at the moment, so Mega Empoleon is the 39th entry of the project. Empoleon was introduced in Generation 4 who's Water/Steel which makes it the only starter with a unique type combination.

I thought about making Mega Empoleon more regal as it based on an emperor penguin and design taking inspiration of Poseidon due to trident shaped aesthetics as shown on the crown-like beak. I've had to add a cape based on the patterns from the underbelly and added shoulder pads to make it feel like an emperor.

Empoleon's type combo will be carried over in its Mega Evolution still being Water/Steel however I'll make it an special attacking tank with stats being focused on mixed defenses and Special firepower at the cost of low speed unless it's need for Trick Room builds. Next Mega Empoleon gets access to Lighting Rod which turns one of its weaknesses into an immunity leaving it only two weaknesses Fighting and Ground. As Ferrothorn and Toxapex, defensive Pokemon work best if they have a type with as much resistances, access to Defensive abilities like with Regenerator or Iron Barbs or Intimidate and access to recovery moves. Empoleon sadly lacks recovery moves so giving it Life Dew is better than nothing because it least it's helpful more in doubles.

Mega Empoleon Stats:

HP: 84

Attack: 86

Defense: 148 (Goes nicely with Steel)

Special Attack: 146 (Gives Lighting Rod a purpose)

Special Defense: 136

Speed: 30 (Worth it if you're defensive)

Pokedex Entry:

"Mega Empoleon have wings that become shields that not only conduct electricity to protecting its allies as it takes the role of the Emperor not also guides its allies in victory, though time-pacing and concentrated calculations.

Despite being starters, not all of them from every region are lucky enough to get Mega Evolutions as Typhlosion was the first listed in the National Dex to lack a Mega Evolution so Torterra is the first Grass starter that lacks a Mega Evolution so I'm making sure every starter doesn't get left out when designing fan-made Mega(s). Torterra is a Grass/Ground with three regular weaknesses to Bug, Flying and Fire and a 4 times weakness to Ice and only resists both Rock and Ground and grants an immunity to Electric. I'm making Mega Torterra a all-around defensive with physical firepower backed up with Shell Smash and strong attacks. Mega Torterra gets +35 increase to Attack, Defense and Special Defense while -35 from its Special Attack and +30 to its Speed to allow easy Shell Smash sweeping.

Mega Torterra's Ability will be Solid Rock which is perfect for a Pokemon with good defensive stats and access to recovery like for example Synthesis. Solid Rock decreases super effective damage by 25% which Torterra is able to take some hits before setting up with Shell Smash and all Mega Torterra can dish out damage with Wood Hammer or Headlong Rush/Earthquake.

Pokedex Entry:

"The result of Mega Evolution will result in Torterra being mistaken for a living jungle with emerald crystal shards glowing a green light after consumed with photosynthesis."

I want to introduce you to Mega Leafeon, another Gen 4 Eeveelution that's worthy of a Mega because Eevee is very popular as it appears in many merchandises alongide series mascot Pikachu becoming the secondary mascot of the franchise. Now that Mega Leafeon is finished, there's one Eeveelution left that demands a Mega Evolution and you know what I'm taking about. I've decided to make Mega Leafeon a Grass/Ghost because if you think about it, the Moss Rock and Old Chateau are both located at Eterna Forest, the Moss Rock is if you're familiar with is a requirement for Eevee to evolved into Leafeon and nowadays it can also be obtained via using a Leaf Stone.

Pokedex Entry:

"Leafeon experiences some haunting memories causing it to Mega Evolve consumed by spirits that control its will close Ghost Pokemon are able to take control of the Moss Rock."

*Phantomise

A made up variation of Pixilate that converts Normal-type moves into Ghost-type moves with 20% boost and Leafeon has access to Normal-type moves that take advantage of this ability.

Mega Leafeon gets +30 in its Attack, +35 in both Special Defence and Speed. This makes Leafeon a physical sweeper with an ability turns all Normal-type moves into Ghost-type moves so it'd be dope for Ghost-type Double-Edge or Body Slam, wish Ghost had better physical moves.

Pokedex Entry:

"After interaction with the Ice Rock, Mega Glaceon discovers that there are rock glaciers attached to its body and its paws have been crystalised yet still emitting fresh snow energy."

Mega Glaceon is up next with Leafeon and Slyveon still left to cover so I've want to make it Ice/Rock because the officially Pokemon like Aurorus and Hisuian Avalugg have this type combination but unable to achieve greatness as their stats are built to be defensive and types are made to be offensive. Ice/Rock can hit Grass, Ground, Dragon, Flying, Bug and Fire for supereffective damage however this type combination is weak to Grass, Water, Ground, Rock, Steel and Fighting. It's preferable to have this weaknesses as long as the Pokemon is built as offensive speedster. I'm making Mega Glaceon how Rock/Ice can be made into a Pokemon if given the right, stats, moves and abilities and this is what worries me, I want each Pokemon to perform greatly in both playthrough and competitive.

That's why my take on Mega Glaceon is gonna be Ice/Rock with those points being added to Special Attack and Speed from 130 and 65 to 160 and 135 respectively, Mega Glaceon will be the first special Sand Setter that'll get Rock-type Weather Ball which 100% accuracy and 100 Power which is needed for Special Rock-types sweepers. It gets Sand Stream as it makes it easier for allies and itself to take advantage of the sandstorm.
