What protagonist is most powerful in relation to their enemies? In other words, who has the biggest power gap between them and the bad guys?

-Racob has spoken

Well for a lot of his enemies Batman....of course he has people like Bane, League of Assassins, Prometheus, etc, but then you have Penguin, Riddler, Two-Face, ect.

Agent Texas.

Ezio Auditore da Firenze.

GRAND MASTER LUKE SKYWALKER

The only correct answer is Saitama the OnePunch-Man. That's literally the entire premise of that manga.

Wally. He has some legit villains in Zolomon and Thawne but for the most part they need to dumb him down tremendously for the majority of them to be a threat.
