Kabuto Yakushi (薬師カブト, Yakushi Kabuto) is the comical side antagonist of the series. He is the assistant, personal medical-nin as well as the right-hand man of Orochimaru.
Kabuto has silver hair tied in a ponytail and black eyes with big round glasses. He wears purple shirt, white under shirt and purple pants with white cloth wrapped around his waist. He wears no forehead protector.
Kabuto acts a bit like Orochimaru's caretaker and usually has to pick up the pieces of Orochimaru's failed schemes. He also tends to do the punchline and usually jokes that Orochimaru has a low IQ.
- In episode 26, Neji comments on Kabuto appearing, calling him a traitor and wanting to attack the Konohagakure again. This was a reference to the original series, as Kabuto first appeared as average Konoha genin, but was actually a spy sent from Orochimaru to help destroy Konohagakure.
