There are two lines of thought on this...
You can think Fattora and Twearkbull are just two bums whose one is a fat bozo out of shape, non-logia user and lack of feats, and the other who got clowned by God King's powerful Haki, pushing down the Admiral agenda and making readers believe Admirals~YCs. It is C3> new admirals bozos.
Or
You can think Fujitora and Greenbull are two goats whose one is an Supreme Grade blade user(potentially ACoC) plus broken Paramecia, and the other who has an Black Blade and negg diffed YC1s plus Weevil, upscaling Admiral agenda and ending the Admirals~YCs nonsense. It is C3~New admirals chads
The choice yours.
