A loyal subordinate willing to fight Kaidou alongside his Captain despite tough odds of victory, level headed, grasp about opponents abilities(reads em well) and think things through like proposing an Alliance. Also took on weak Smile for his Captain sake(knowing it won't do him any good), and became Orochi tool to kill random people in Wano, despite laughing uncontrollably the very same thing he always had issue with, makes him quite an interesting character.
His fighting style is also good, more so with those scythes, he appeared insane while carelessly moving in those scythe and those moves, something very Original that Oda often don't do. At the same time i was quite disappointed from him as a fighter. Now that it is confirmed he was nerfed, maybe Oda can redeem him somewhat.
