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 that this 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 be unable 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).
