One Punch Man is a different kind of Hero. So is this challenge. Different in the sense you'll not be able to achieve it. Do you want to find out what Saitama did to get his Powers? For Three years. Yeah that's it. Hard mode for three years and you become One Punch Man. No need to check in. But you can certainly try "Im just a guy who's a fapstronaut for fun"
Wow. Childhood goal achieved!! 3 YEARS NO PMO never thought I'd make it. I am my own hero now! *tears up ONE PUUUUUNNNCHHHHHHH!!!
