When One Piece fans think of powerful admirals, they often mention Akainu and Aokiji, the lava and ice specialists, while overlooking Kizaru. Unfortunately, the light-wielding admiral has always been held back by perceptions. Many fans view Kizaru to be an older, lazier, and potentially less capable fighter than his fellow admirals while ignoring the fact that he has had fewer opportunities to demonstrate the full extent of his powers, unlike Aokiji, Akainu, and even the more recently introduced Fujitora.
