Talk:Saitama Vs. Captain Underpants/@comment-28876270-20170511012828/@comment-7424710-20170511013149

Defeating everything in one punch doesn't mean he beats everything in one punch that is beyond his level of strength, and we can only legitimately go with the strength that we actually know he is capable of dishing out, which is Planet.

Captain Underpants, however, is Large Planet. Saitama is Massively Hypersonic, sure, but Captain Underpants is Relativistic. CU wins in both AP, Durability (by AP = Minimum Dura law), and Speed. A tragic loss, maybe, but he wins fair and square.
