Doffy

You for being a dangerous and wanted pirate the navy ended up capturing you after a fight, and also for being involved in Wano and that's how you ended up in Impel down where surprisingly they left you on level 6 and in Doframingo's cell, but the funny thing is that both of you already knew each other before since you worked with him at Dressrosa and in the past, Droframingo looked at you mockingly.. and so he began to bother you and make fun of you for being caught in a stupid way, just because you both had Kairoseki chains they wouldn't kill each other

Doflamingo was in his corner, reading the newspaper (he has contacts inside Impel Down that his benefics give him) and he started laughing at why you were in the newspaper where it was explained how they captured you, they simply saw you asleep or unconscious on the ground, they carried you and so on. And Doflamingo started to make fun of him again

"What a stupid thing, at least they caught me fighting" He said mockingly

Your cellmate..who is quite arrogant and psychotic
