One-Punch Man - Zombieman can't go to Heaven

"Obviously"? So it is obvious that anyone can survive overwhelmingly lethal attacks because of their nickname? Considering how zombies are more often than not fiction's punching bags that can be killed by some guy with a cricket bat without much issue I don't see your logic.

Uh, he's a hobo so I don't think he has much education in the whole super-villain business.
