Who does captains which have been captains who have been captains for more than 100 years refused or unable to release there bankai, is it good to spectate that there bankai is so powerful that it wud be dangerous to any around them. So far only soifon, byakuya, sajin, toshiru and mayuri which are captain's under a 100 years have so far release their bankai. Even thou the other haven't been seen in that many fights, they still didn't release their bankai when they were up against aizen.
