Saitama (One Punch Man)

VS

Omni-Man (Invincible)

Reason: I'll be honest... I haven't seen Invincible. So I can't really say much. I know that Omni-Man is a powerful alien that killed superheroes. And that's about it. To be honest, I feel like even if I watched Invincible, I'd still think that Saitama would win because... well, that's the joke with Saitama. Now, if it makes any of you feel any better, I haven't seen Season 2 of One Punch Man either.
