so.... what do you think of him?... (I find him pretty cool guy)

Ah, the day when I write my sequel shall be a glorious one with him added

One of the best antagonists in quite a while, his devil fruit ability made it almost like Luffy was fighting himself. He was strong enough to be push Luffy to his limits but also had a sense of honor, without which Luffy probably wouldn't have left Whole Cake Island alive.

He singlehandedly raised the arc from "ehhhhh" to "alright" for me. If not for him, the entirety of the arc after the collapse of the castle would've felt meaningless to me.
