Fist of the Madman

Rumor has it that if you talk trash about Class 1-A, Tsuyu breaks into your room and beats you to death with a pipe.

Hands:

No, not that one, this one:

Yeah, yeah, we all know about the scars, in fact, you can see them in the dream sequence...

Which then leads to-

Clearly, the brother, as I’ll call him, somehow interacts directly with Deku, which as stated in the chapter, goes against All Might’s knowledge

I have to assume that at this point in the story, All Might wouldn’t be keeping this kind of secret from Deku, which leads to the question of why didn’t he know, but that’s a whole different topic...At any rate, what the brother does here causes an explosion of some kind in the real world

So, what the heck, yeah?

It would seem as though whatever happened in the OfA dream repaired the scars on his hand. I would wager that the damage to the ligaments in his arm has been reduced as well. Along with this quote, leads me to question-

Call me crazy, but a pure strength quirk doesn’t strike me as suitable for someone so atrophied, stockpiling or not. This is at odds with All Might’s previous knowledge again. Does transference of power necessarily mean strength? Did other things get passed down without notice?
