Deku is a self insert MC that appeals to the "I'm such a nerd" faggots. He has this bland sob story that's supposed to make you feel for him, about how he looks up to AM because he watched some youtube vids, and wants to be like him of course. He finds out though that he's 1 out of 5 people who don't have quirks and gets super durrpressed. But again most people in his world have either shit quirks or no quirks like him and don't get to be heroes. Which just makes Deku come off as an entitled piece of shit who makes his mom over eat because she feels responsibl just because he couldn't get over something he found out about when he was like 5.
Then through a super contrived series of events he conveniently gets handed the most powerful quirk. And now we are supposed to follow him on his journey and be impressed that he's going to make it even though he has far and away the most powerful quirk?
It's ridiculous watching the series make a big fuss about him going up against a guy who's got swords!! OH NO!! Then even when his opponents do outwit him somehow even though he's already been informed of what their quirk is, his plot armor kicks in and is saved.
So obviously he's retarded which is why I don't get why people say he's an intelligent MC just because he can come up with some basic plans that rely on how ridiculously OP his quirk is. Like I'm gonna blow a hole through a 3 story building with my punch and you do your thing Ochako while the opponent is caught up in the explosion. I'm gonna punch this lake into a whirlpool and you guys use your quirks and do what you do. You would have to be retarded to be impressed by that, I've seen
