Kenpachi has a wild and aggressive appearance, fitting with his personality. He wears his captain's jacket without sleeves, and with a more ragged look to it. He acquired his Haori from the previous 11th Division captain, whom he defeated and killed in a duel in order to become captain. He styles his hair into liberty spikes with bells at the tips, which, Tite Kubo has remarked, makes his hair one of the most difficult to draw in the series. He also wears a special eyepatch on his right eye lined with a strange creatures mouths; the eyepatch was created by the 12th Division. It absorbs the bulk of his power. Both of these are meant to give enemies an advantage, similar to his habit of fighting one-handed, since in an unhandicapped state he would defeat them so quickly that he would not be able to enjoy himself sufficiently to delve into a state of bloodlust, that being what he treasures most. He has a huge scar on the left side of his face, which was given to him as a child from his first ever battle with Retsu Unohana.Despite his initial introduction as a lethal foe, Zaraki later begins to play the role of the antihero in Bleach: though still self-centered and violent, his actions tend to be for the best and his relationship with his division and others. This shift is primarily centered around his appearances in the Bleach anime and omake stories, with the exception of the occasional diatribe between himself and Yachiru. He is depicted as having a very poor sense of direction, and is often depicted in omake stories asking his lieutenant Yachiru for directions to a particular place (who then randomly points in a direction even though she herself has a terrible sense of direction as well).Kenpachi lives for battle (evidenced by his method of attaining his rank) and enjoys a good fight more than anything. He restrains himself in battle in order to prolong and savor the fight. Kenpachi believes that injury and death are nothing more than the price one pays for a good fight. Despite his squad's reputation as the most bloodthirsty of the Gotei 13, they have their own code of ethics, different from the set rules of Soul Society, fitting with Zaraki's portrayal as a free spirit. On various occasions, Kenpachi is seen putting fun before work. Despite his violent tendencies, Zaraki will usually give up on a fight if his opponent is too injured to fight back, claiming that the fight is no longer fun. However, he will unhesitatingly kill his opponent if they refuse to end their fight on his terms as seen during his battles with Tōsen and Nnoitora.
