Saitma vs Gojo

Gojo is one of a scarce amount of anime characters that could beat saitama. And quickly, at that. Because of Gojo's infinity, he's untouchable, which is a problem for one "punch" man. While something like a table flip might have a chance at damaging Gojo since he can't phase through objects and debris, he may use his insane speed to get behind Saitama. Plus, Gojo could end the fight in seconds by using red, domain expansion or hollow purple. TLDR: Gojo is untouchable and could kill Saitama in a single move.

A quick summary of OPM vs Goku

This battle isn't anywhere near close. I've heard people say that "Goku has the powers of a god!". So did cosmic Garou, and he got single handedly (literally) defeated by Saitama, while still holding Tareo's promise. Let's say that Goku, for some unexplained reason, killed Genos. Goku is gone, vaporized. OPM has never gone full power to defeat an opponent, whereas Goku frequently has to. OPM killed Boros easily, a being with great power, and yet saitama two shotted him, despite one of the shots not even hitting directly. TLDR; Saitama's whole gimmick is he doesn't have limits. Goku wouldn't pose much of a challenge. ------------------ Edit 1: Replying to @Ghoul~~Chan Saitama i don't think would count as a gag character. sure, he's funny and all, but he's complex in the fact that he has a dilemma over being unable to be given happiness from a hard fight. He's more than a gag in my opinion.
