A/N: One Punch Man vs Marvel.
Austin: my best guess is that they'll have Gray win.
Esdeath: you don't think I can win a fight?
Austin: never said that. It's the case of the power output that Fairy Tail characters might have. I haven't exactly seen the anime or read the manga. But I can imagine that they're pretty powerful. Not as strong as characters like Naruto or Luffy, but still strong.
