>>113349504Touma isn't actually hard to beat, he can be beaten by hundreds of different low-level heroes or villain who don't depend on unusual powers to fight.
Conversely, Touma can beat (or, as a team effort, enable the defeat of) some of the highest powered beings in capeshit. If Touma has a hand on the Infinitely Gauntlet, despite all of its power its just a fancy glove. He can depower Thought Robot Superman into 'just a guy'. His power neutralization is bonkers high level.
You really have to consider him as less a fighter in his own right, and more of a kind of silver bullet for taking out otherwise impossible foes.
