Narratively, All Might takes it, laughs and punches her into space.
When you say narratively is that an attempt to disregard feats depicting otherwise by saying it doesn’t make sense in story?
What if I say narratively this doesn’t make sense.
For example… Tomura, who isn’t physically capable of reacting to All Might, could actually perceive All Might’s movements and was shocked by the fact that he could.
P
WAM was still the strongest hero around with AFO making a joke out of everyone else. He was so strong that obessesed nerds like Deku and Hyper obessesed rivals like Endeavor has no idea he has gotten weaker.
All Might in his prime never had to use his full power against anyone but PAFO. So why would they be aware of him weakening if they never actually seen that power? (This is also sorta retconned, because latter in the series people started referencing prime All Might levels of power despite not being aware of it early series.
Deku references it in the Dark Hero arc, Hawks references it, Best Jeanist references it, edgeshot references it).
Endeavor and Todoroki and a couple heroes being capable of immediately determining that Deku/USJ Nomu were comparable to WAM’s 100% implies that at some points All Might had to use 100% against some people regular for people to have an understanding of that level of power and to make accurate comparisons of it.
Also, Endeavor, someone capable of accurately accessing weakened All Might’s strength, believed someone with his Firepower and the ability to cool themselves down would actually surpass All Might. Just noting that.
Shigaraki was literally told by AFO that "Yeah you will have easier time, he is weakened after we nearly killed eachother."
His first reaction to seeing the goat was, "Master lied, he isn't weaker at all."
AM specifically had to go beyond his 100% to defeat the Nomu. Tomura, was shocked by this and couldn’t believe he got weaker because as he just saw, All Might appeared stronger than what he should have been.
AFO confirms that AM was indeed weakened.
Because the narrative shifted from "Number one symbol of peace" to "Unity and team work." The titans of the verse got shafted into being weaker or just incompetent.
Tbf, even with All Might helping make plans for the final war, the heroes thought Endeavor and an out of prime Hawks could take out AFO 2v1 despite him going High diff with All Might. The cliff between these them and the verse cannot be that high if they felt like Endeavor and hawks could 2v1 a straight up established All Might level fighter.
