Fujitora’s rubble feat was hundreds of times more powerful than ISDS, and that wasn’t even an attack from Fuji but just him flexing lol.
Big Mom with Napoleon is in the same tier as Fuji. Both of whom destroy Zoro.
No it is not an AP move, its just him applying gravity in large area, strongest AP Fuji has shown was raging tiger on Luffy, second strongest being one he used on Zoro so far.
If Fuji drops all the rubble as is, Zoro just has to cut a part of it.
If he launches galling Zoro just needs multiple slashes.
I don't know where the 100 times bullshit is coming from. Big Mom with Napoleon destroys Fuji. She has feats of fighting a top tier for days unlike Fujitora and since you value feats so much, Fujitora by feats neither has history nor present of fighting a top tier.
