A bald guy named Saitama, who is a hero for fun and he can technically kill people, aliens or whatever he's fighting with - like the car alien- with one punch. He has a "student" named Genos and he's a cyborg, they applied for the hero association and their names are "Bald Cape" and "Demon Cyborg"

It's a very awesome, lit, funny anime so you should watch it.

A bald boi who can fucking kill anyone and anything in one punch. He's so powerful in fact, that there's never a single moment when he's at his limit or uses his full power.
Hey dude did you see One Punch Man the other day?

Hell yeah it's freaking awesome. I wonder when there will actually be an enemy strong enough for One Punch Man to actually have to try to defeat.
