[@olcharlieboi] If you wanted balance, keeping his abilities temporary would probably do the trick. I mean, initially he'd have trouble getting quirks, but in due time, he'll eventually learn how everyone else's quirk works, so copying wouldn't be that much of a problem. And I'm assuming that once he understands a quirk, he'll automatically get it? Or is there a trigger that I missed somewhere like touch or being within close proximity from another quirk user?

Just curious on how he copies mutations? Let's say Makoto's? He'd become a massive oni too?
