to me i like his loyalty, hes no pushover, he is a badass, he is number 1 swordsman, trained under mihawk, he is also kind, he wakes people up when they needed to be woken up, and he has TONS of badass moments and has a platonic relationship with luffy. his rivalry with sanji is funny and his willpower is something else. and i like his evil grin when he battles those he deems a exciting battle. and hes kind of like a samurai himself. so yeah. he is a badass.
