Flex's quirk is actually really OP now that I think about it. In another episode he said that not many things can hurt him, which I'm assuming is because of whatever his body is made out of. (Mario said that it was gelatin-LIKE so we don't really know what it's made of exactly) So not only can he turn into people but he's also more tanky than anyone else.
Alright I need to get this off my shoulders but in my eyes flex’s quirk is very underestimated if I am correct at the fact flex might be able to use mutant quirks flex got from others from morphing into them the only draw back I see from this is flex will need to learn how to use that morphs quirk and learn it but the up to flex’s quirk is that flex can keep that morph with that ability he whip out someone’s quirk at a time like let’s say someone has a mutant quirk which gives them a tail flex could touch them and get that tail or any other appendages the quirk might have flex will then need to learn how to use that appendage because his body will probably not be used to having something like wings or a tail. Another problem I see is that he will not be able to use that quirk in that fight but will have to learn how to use it later on. This isn’t 100% true but it’s just a thought
Hmm. Theory is while his parents or whatever wanted to have a kid. Flex's mother had a miscarriage. And them both not wanting to take chances in having that heartbreak all over again. They instead decided to make their own son. Mixing both they're DNA. And through some mistakes. They had the child be deformed.. so they had em home schooled. However. His quirk fixed all that. Him getting a new look. From a deformed child. He became a yellow figure with no face.
@Commander Bruh-Lox i have Real Mustache I mean. I still am allowed to make theories. Nothing is stopping me from doing it. I just got bored and made this theory. It still sounds probable to me. So I wrote it down here.
If he can replicate Mario’s voice. The evolution of his quirk copying people’s powers are a sure fire possibly. Although now their going to have to change his character bio to just quirks he can’t copy now.
@@infamouse9263 True, I mean we’ve seen how quirks evolve in My Hero so If flex quirk does evolve to replicate even someone’s exact height. Then he might be able to copy someone quirk if his evolves to do so.
