Yes. Always. Good lord. I never understand why people can turn this into a big serious discussion. Yes, One Punch Man would beat Thanos. He would beat Luke Skywalker, Superman, every single character from Dragon Ball Z, and every ninja from Naruto. He would beat Thor and Wolverine and the Hulk in a tag team match.
Because he plays by different rules. One Punch Man is a PARODY character. His skill set is defined by comedy, not power levels or physical strength. One Punch Man not Superman facing off against an ever-more powerful lineup of villains. He’s the Roadrunner against Wil E. Coyote’s ever more convoluted plans. Deadpool is the only other super hero type character who comes close to living in the same realm of parody, but frankly, Deadpool repeatedly getting the crap beat out of him would be funnier than Deadpool winning, so One Punch Man would win that fight too, even if he can’t actually kill Deadpool in one punch. Because parody.
If I see another Youtube video recommended to me like “Could One Punch Man beat-” really, truly, I do not care.
I saw somebody also make this point once in another great post, I’m paraphrasing from what I remember; how strong is Saitama? However strong he needs to be in order for it to be funny.
the only “could one punch man beat” I’m interested in roger rabbit
saitama vs arale would be a fair fight since they are both on the same power level of “only strong as they need to be to win”
