@GoldDiamond what happened to your boy Coby? Failed to do shit to Hancock, got captured by Blackbeard, while Hancock fucked majority of Blackbeard's crew.
I mean, Kizaru got cockblocked and said that they would need special prep
to even attempt to capture him (note how severely injuring and k.o.ing Rayleigh also counts as capture and that bounties are dead or alive, so they don't have to capture him alive).
Rayleigh is just built different.
