User blog comment:Nobody700/How is he so strong?/@comment-27209729-20151221014625

if you remember what he said when he fought crablante: "When I was a little boy I wanted to send evil guys like you away with one punch" and if we look at how most of our guys got their powers was through pure obsession or dedication IE: Mach K9 car guy, Crablante, etc. they transformed because of their obsession of that, while Saitama's obssession is to be a hero. That's how I think he got his strength.
