Kabuto Yakushi is Orochimaru's personal medic, assistant, and general right-hand man. Kabuto was found as a young boy by a chief medical officer of the Konoha Medical Unit Squad. The officer brought Kabuto with him back to Konoha and raised him as a son. Kabuto eventually began acting as a spy for numerous countries and organizations (such as Akatsuki) before coming under the servitude of Orochimaru. Kabuto has since used his various former affiliations as a means to gather intelligence on Orochimaru's behalf.
