Zaraki Kenpachi

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 jacket from the previous 11th Division captain, whom he defeated and killed in a duel in order to become captain. He styles his hair into 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 eye patch on his right eye lined with a strange creature 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, as 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, apparently gained well before his time in Soul Society (and even before finding Yachiru).

Despite his initial introduction as a lethal foe, Kenpachi later begins to play the role of the comical anti-hero in Bleach: though still self-centered and violent, his actions tend to be for the best and his relationship with his division and others is always portrayed comically. This comical 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).

Kenpachi lives for battle (evidenced by his method of attaining his rank) and enjoys a good fight more than anything. He even weakens himself in an effort to make any fight last longer. He also claims that injury and death are nothing but the price one pays for a good fight. Despite his group being the most bloodthirsty of the Gotei 13, they have their own code of ethics, different from the set rules of Soul Society, fitting with Kenpachi's portrayal as a free spirit. On various occasions, he is seen putting fun before work. Despite his violent tendencies Kenpachi 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 Tousen and Nnoitra.
