Like most of his clan, Kiba has messy brown hair, sharp black eyes with slit-like pupils, canine teeth, and nails that he can change into claws. He also has the distinctive red fang markings of the Inuzuka clan on his cheeks. Kiba is often short-tempered and impulsive, but playful and overprotective. Fiercely loyal. Argumentative and temperamental. At a very young age, Akamaru was given to Kiba by his mother, Tsume, and the two became very close soon afterwards.
