Kabuto Yakushi is a major antagonist of the series who was first introduced as a Konohagakure genin. He was orphaned by war as a child, and was found by Nono Yakushi and raised in the Konoha Orphanage. Upon reappearing shortly before the outbreak of the Fourth Shinobi World War, it's revealed that he's learned to fully control Orochimaru's genetic material, causing him to take on many of the physical traits of his former master. He wears his hair in an unkempt bowl cut, allowing it to grow out. He wears a maroon-coloured cloak with a hood designed to resemble a serpent's head, with white, red, and yellow markings that resemble eyes; the hood can be closed like a snake's mouth to help protect his senses from the effects of genjutsu. After Orochimaru's sealing, Kabuto travelled across the world and ultimately discovered the location of the Ryuchi Cave. There, he was taught senjutsu by the White Snake Sage where he gained access to a Sage Mode. Physically, Kabuto undergoes little alteration in this form, with the only visible changes being the markings around his eyes extending onto his back and the growth of four horns on the back of his head, as well as darkened sclerae!
