There are no direct small city+ dura feats, the most we have in that front is the All Might storm and Bakugo, who also performed a far higher feat than that literally a minute beforehand. All the High Ends are coming off of scaling to USJ Nomu, so they are not exactly “limited” by feats. Also, cool, you realize that this High End is indeed as strong as Hood physically.
You’re the one making a wild assumption. You have no evidence whatsoever that this Nomu has an unknown quirk that just managed to perfectly allow it to survive this attack. And even if it did, it doesn’t matter, because it was already wounded severely when it hopped into it.
Lets go over this Nomu, shall we?
It does not have any form of shock absorption (we see Star punch it with her stand.)
It does not have any form of heat resistance (it is burned by the lasers similarly to Shigaraki)
It does not reflect damage (passively or actively)
It does not have any visible indicators to increasing its durability such as higher muscle fibers, shields, bubbles, forcefields, sinking into itself, hardening its skin or anything.
There are ZERO abilities in the ENTIRE VERSE that this Nomu displays TO EVEN HINT that it has a durability enhancing quirk. There are no statements on it being different. It was not brought to take attacks to our knowledge, only to help Shigaraki fly, as he clearly does not have Air Walk. It’s only noticeable qualities are that it flies and has regeneration, similar to Hood.
So, Damage, you tell me. What is the most absurd option?
Accepting this Nomu is impacting our scaling through a direct feat from the manga? The best feat so far? An extreme downplay upon its abilities to the bare minimum? Realizing that the verses absolute top tiers are stronger than we thought? That we have a concrete, Manga feat for a top tier after 300+ chapters?
Or assuming it has a special, super secret quirk that has never been hinted at or existed nor resembles any other defensive quirk in the entire series? That it’s a special Nomu that never used this durability enhancing Quirk until right now to survive missiles when it was going to die right after anyway? That this special quirk exists for it and it alone, with no name or explanation given? That Horikoshi intentionally omitted this Nomu’s quirk info just for it to survive so he can put trust in his fans to extrapolate that “oh of course this Nomu is just different from all the other ones, it has a durability quirk, good ol’ Hori!”
Tell me, Damage.
