Kabuto Yakushi is an antagonist of the series and was Orochimaru's former personal medic, assistant and general right-hand man. He is now a critical threat to the Allied Shinobi Forces after developing his newfound powers and then apparently allying himself with Madara Uchiha.Kabuto has black eyes with grey hair kept in a ponytail and wears circular glasses. He wore a dark purple shirt with a white undershirt and a white obi around his waist worn at an angle. He had dark purple pants and a shuriken holster on his right leg. He previously wore an Otogakure Forehead Protector and dark purple gloves with open fingers in Part I.
After attaining control over Orochimaru's remains, his appearance changed drastically. He looks much more like his former master, having the same markings around his eyes. He has slitted pupils reminiscent of Orochimaru, and his hair is slightly shorter but more unkempt. He still wears his glasses, but now has scales on his face and neck. Kabuto wears a deep purple cloak with two bright red, white and yellow markings similar to eyes on the hood. He also has a snake coming out from the back of the cloak, in a fashion similar to a tail.
