One-Punch Man

[KrayZ33]

Saitama didn't punch Crablante at all. he ripped his eye out. He even took a beating and was injured and bleeding. Saitama 3 years later doesn't bleed and doesn't use anyhing but punches - that's because he was normal before, who had to use anything at his disposal and was very well killable, and now - after training - he's not.

Saitama was like Mumen Rider, unless you want to give him some super powers, even though he clearly doesn't have any, you are wrong. There is no indication that implies that it is somehow impossible to beat Crablante without dormant super powers.

If we are being super technical about this, neither resistance nor strength was enough to rip apart the tie he used to rip its eye out.
