“Captains good to bad” requested by anon. :)
I’m not actually sure whether this requester was talking “good to bad” in terms of ability or morality. But I’m gonna go with morality. Because. So let’s consider: if the captains were arranged from most good to most evil, what might the order be?…
You have only to watch the Starrk fight to see how sadistic Kyoraku really is - and how bone-chillingly scary. Plus he has a bankai he can’t release in public. Basically, Kyoraku, like Unohana, definitely has a killer inside that he is trying to suppress at all times.
Kyoraku: But I have a pink kimono! How could I be evil?
Ukitake: Mr. Sadistic-Kimono! That’s what she should have called you!
Kyoraku: Not helping, Ukitake.
Mr Sadistic-Kimono xD
