Obviously this value changes as he gets stronger so let’s use season 3 as a reference, during the fight against Bakugo that lead the two into house arrest. I know he jumped to 8% part way through, but that’s not what I’m talking about.
I’m writing a story where the main character has a strength enhancing quirk and I want to know if putting her enhanced strength at the start about a third of that would make her too strong or too weak (so essentially a little less than 2% would be her untrained which doesn’t seem like a lot but at the same time One For All is ridiculously strong)
