soul reaper
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 styles his hair into spikes with bells at the tips
Zanpakutō,
Kenpachi is the only captain of the Gotei 13 who doesn't know the name of his sword, nor can he use his bankai as a result. In addition, he never uses kidō and rarely uses flash steps. The Bleach Official Bootleg databook ranks his talent in the former as zero. However, he more than makes up for his faults in sheer power. His spiritual pressure is such that, even when wearing the energy-sealing eyepatch, Kenpachi can fight on-par with other captain-level opponents, even when they release their zanpakutō in either shikai or bankai form. Its concentration is so great that it acts like armor against weaker opponents
Prior to entering the Soul Reaper ranks, Zaraki resided in District 80, the most lawless district surrounding Soul Society. He became very proficient with swordsmanship while he was there; or at least fighting, and eventually adopting the district's name, "Zaraki", as his surname
