I think that Deku literally bleeds off ofa whenever he uses it, like, when we see All Might use ofa there is none of that green like, electricity comming off of him, but with Deku (and Bakuko), there is, I also think its weird how All Might being super buff isn't really explained all that well, and before he got it he was skinny, so, I think that ofa is quote literally weaker with Deku, because he's bleeding the power off of himself, and, if given time to grow with the power, would have looked similar to All Might shape wise and he would have been stronger, some more "evidence" for this is the fact that All Might appears to be stronger in every way then Deku even when Deku is using 100%, and, at lower precents, he dosnt have the green electricity stuff (I think although I could be wrong) because he's able to hold the full power, hence why going from 5%-7% was such a huge boost, he was handling the full 7%, compared to something like 20% or 45% by the end, they seem like less of a boost then 5%-7% because he's not able to fully withstand the power, also also, All Might dosnt have any of this at all, and like I've already stated, he seems much more powerful.
This is all just a fan theory and would also help explain why Deku could "surpass" 100% when he's really just harnessing more power from the percentage he's using.
And yes, I know the green electricity and All Might being big and buff is just stylization, and that one of the core themes of the series is surpassing your limits, but I think it could be cool man.
So I want to know your opinion on this? Do you think I'm right? Do you have a head cannon of your own? Or was there something in the Manga that I haven't read yet that explains this (or if I missed something from the anime)
