There doesn't seem to be a thread dedicated to discussion and speculation about Quirks, their origin, how they work etc. So i thought I'd start one. Yes I'm aware (or I'm pretty sure) it was stated in the manga that quirks are mysterious and unexplained and nobody knows anything about them and where they came from and blah blah, but Jesus Christ i get so frustrated with some of the bullshit quirks that get introduced in this series. That little statement about quirks being mysterious gives the author such a free pass to asspull anything he wants. I know i shouldn't be looking for any consistent internal logic with quirks, but i can't help myself. As i read the manga, i keep finding myself accepting that quirks are genetic mutations similar to mutants in the X-men (would make sense given that the whole series is an homage to American comics) due to the abundance of easy to understand quirks like Tsuyu's, Kaminari, Momo, Tetsutetsu,Todoroki, Bakugou etc. But then every 20 chapters I'm hit with some mystical HxH/FT/Naruto ( i can't get over the extreme similarity to HxH with the constant mention of "conditions" or "drawbacks" with every quirk. I mean can't a guy just be born with a badass quirk? Seriously.) type quirk like OFA, that Black hole teacher, Eri, some guy with his elbows, hands and shoulders all floating and detached from one another, and then you have crap like villains scientifically implanting these quirks into like 1000s of people to create Nomus. This sounds like a rant but i really just want to start a discussion on what they really are and how they work.
