Bleach: Weakest Bankai

For those capable of activating it, Bankai is the ultimate release of Shinigami’s Zanpakuto in Bleach, boosting their power to levels unseen while conferring unique abilities that correspond to the nature of their blade. All Captains in the Gotei 13 are expected to be able to perform Bankai, with the only exception among them being Kenpachi Zaraki, the Captain of the 11th Division, until he eventually awakened it. Generally used as a trump card against powerful opponents, activating Bankai is not something an opponent would normally take lightly.
