Big Mom used an attack ten times stronger than Jinbei's on Ulti but she still managed to get up, and some people here think that WW is done?
The fight is far from being over. We still have two chapters of WW vs Jinbei.
You realize that Jinbei broke both of his arms, and a finger broke on his own attacking him, and then destroyed Who's Who floor (Breaking the room and a bunch of pillars) with one attack? This seems like a symbolic defeat already. Like Luffy destroying the place of the villain when fighting.
Not only that. Who's Who already used ALL Rokushiki skills while in Hybrid Form to Jinbei's FACE. Just tanking it. Doesn't matter if Who's Who gets up, he has been defeated on a spiritual level. His attacks can't down Jinbei, his place is fucked, and Jinbei downed him and broke his arms like it was nothing.
