Fujitora ate the Zushi Zushi no Mi, a Paramecia-class Devil Fruit whose power allows him to create and manipulate gravitational forces, and that is always seen being channeled through his blade (being at least partially drawn whenever the power is used).
Fujitora regularly employs downforces of gravity to push opponents into the ground under immense pressure (enough to cause deep craters and suppress physically mighty foes) or merely immobilize them, as well as to precipitate the falling of large, flaming meteorites from the skies with which to cause massive devastation.
Additionally, Fujitora has shown himself able to negate gravity entirely to enact the controlled levitation of things around him (similar to the Fuwa Fuwa no Mi’s power, but without having to touch whatever he targets prior). Just like his gravity wells used in battle, the range of his gravity negation is immense, shown to work on an island-wide scale.
This is something very similar to what Kaido did in chapter 997.
Kaido ate the Uo Uo no Mi, Model: Seiryu, a Mythical Zoan-type Devil Fruit which allows him to transform into a serpentine Azure Dragon. He has mastered his Devil Fruit powers in that he can access some of his draconic abilities without needing to transform, such as generating Flame Clouds to levitate Onigashima! He was even able to do so while battling against five members of the Worst Generation alongside Big Mom.
Who between Fujitora and Kaido showed the best feat in your opinion?
