Bakuzan's strength
I'll be going over Bakuzan's feats and strength, i haven't fully finished OPM so there might be some things I'm missing.
Human Bakuzan
Suiryu hasn't shown what he's truly capable of at this point either so this statement is based on limited info, still it places him above someone like Sneck, seeing as Sneck is a 6th Time Entry and only places in the top 4 regularly (whereas Bakuzan has won twice in a row) and Sneck isn't ever stated as being in a similar tier of power to Bakuzan.
After Suiryu one shotted Lightning Max and knocked him out in one strike Unlike other contestants who were in shock and awe, Bakuzan was unfazed by this feat, which could imply he believes he could do the same against an A-Class hero like Max.
Bakuzan is quite brutal, having turned countless matches into blood bathes. A stretcher and doctor were at the ringside of his fight and he seemingly threatens to Saitama that he could sever limbs. he states that he could that he could Pulverize bone, blow organs apart, and chop a skull clean open.
Takes a punch from Saitama which sent him flying and with enough force that he crashed into the ground and was buried inside of it. Despite this, he was pretty much fine afterwards, only requiring a bandage over his face and showing no pain overall. whereas others hit by his punch like Zakos and Sourface are still in pain afterwards.
Suiryu thought Bakuzan could help him against the Three Crows who were giving him trouble in the current state he was in.
With all this I'd say Bakuzan is like.. high A-Class in terms of strength. Sneck is a pretty strong mid tier A-Class Hero (you'd think im lying but there are a lot of featless A-Class Heroes or just A-Class heroes with anti feats) and Bakuzan despite never going all out is stronger then him.
Monster Bakuzan
After eating too much Monster Cells that his body could handle and nearly dying, Bakuzan managed survive this and fully monsterize.
Gouketsu states that he hit the jackpot with Bakuzan and considered him Disaster Level Dragon and that he could surpass an S-Class Hero.
This is impressive for a couple of reasons.
Gyoro Gyoro states that it's possible to "reach the next stage" if you conquer death, this was tried before with many success but they all died before becoming threat level Dragon.
Bakuzan on the other hand was able to adapt to death from consuming too much monster cells and he managed to become Threat Level Dragon like Gyoro Gyoro had attempted many times before.
It's said that explosive growth can be gained if done multiple times BUT it's still said if you conquer death you can get stronger from that, never said you have to do it multiple times to get strong, just that if you want to have EXPLOSIVE growth you gotta do it multiple times.
I might be interpreting the statement wrong since I'm not exactly the smartest when it comes to powerscaling so don't quote me.
Seeing as he was conisdered Dragon Level, he should scale above the other monsterized contestants like Volten, who's electricity was dangerous enough that Suiryu had to dodge it and use an entire different person as a weapon to attack instead, implying he himself couldn't touch it. And he should scale above Monster Choze, who was a relative and comparable opponent to Suiryu, being able to keep up with him during their fight and make him put in genuine effort to hold off and deflect a blast from his horns which burnt his hands. Even after Suiryu later broke his horns he was still able to keep up with and clash with Suiryu. Moving at such speeds that Gouketsu had to use all 4 eyes to track their fight and others thought they were equally matched. Suiryu had to use his strongest attack to defeat Choze. Also, Choze made Suiryu bleed, and Suiryu outright states it was really close, as well as if Gouketsu is even stronger then Choze was then it would be tough.
Bakuzan should scale above this based on Gouketsu's assessment of his power.
While his kick didn't do damage to Saitama after it landed it managed to push Saitama back a bit. Suiryu states that Saitma wouldn't be able to take any more hits from Monster Bakuzan, despite moments prior to this, unleashing a full on assault of attacks on Saitama and relentlessly fighting full of passion. He uses his strongest attacks to continue to attack Saitama and deal consecutive strikes to him, even his strongest attack which shattered half of the arena and directly landed on Saitama. With all of this Suiryu having done and knowing that Saitama had no reaction to it he thought that Bakuzan's attacks would be too much for Saitama to handle.
Now I'm gonna be real, there's this one anti feat that a lot of people bring up, when Suiryu breaks Bakuzan's toe.. yeah idk what to say about that one. My main argument is just that Bakuza was toying with Suiryu in this moment, essentially having fun beating on a weakened Suiryu and definitely not expecting him to still have some strength even in his state to outright break his toe.
IDK maybe Bakuzan's feet are just weak or something lol. I mean it is just a toe, I'm not sure it speaks volumes about Bakuzan's trashy durability overall if Bakuzan is really THAT weak then in his human form, Saitama should've blown him to bits with that punch even while holding back (supressed saitama > 1hp suiryu/1 arm suiryu).
so yeah.. idk how to take this whole thing.
Anyways at bare minimum I'd say Bakuzan should scale above people like Early Series Puri Puri Prisoner, Tanktop Master, Early Series Base Metal Bat (assuming Metal Bat doesn't survive and gets fighting spirit) and all of Genos's upgrades before his Post Super Fight one (he harmed Elder Centipede and fried him through his entire body Bakuzan is not beating that shit)
