Kiba Inuzuka is one of the main supporting characters of the series. He is a Chuunin-level shinobi of Konohagakure and a member of the Inuzuka Dog-User clan, as well as a member of the Chuunin team, Team Kurenai, along with Shino Aburame and Hinata Hyuuga. Kiba is usually seen with and fights in collaboration with his partner, Akamaru.

Kiba is often short-tempered and impulsive (in stark contrast to his teammates Shino and Hinata), and can be prone to making mistakes when he becomes agitated in battle. The fact that he enjoys combat, as well as a habit of showing a joyful smile when facing a particularly strong opponent, indicates that he is willing to risk his life for a mission, and is rather bloodthirsty. He deeply cares for Akamaru, and is willing to do whatever is necessary to protect him. And, despite his rather gruff attitude, many of Kiba's actions reveal that he is very close to his older sister, Hana Inuzuka, and remains fiercely loyal to the Inuzuka clan.

Kiba's personality and jutsu style are further enhanced by his wild appearance. While clearly human, he has several physical traits more akin to animals. Like the rest of his clan, he has messy brown hair, sharp black eyes with vertical slit-like pupils, pronounced canine teeth, and nails that he can change into claws. He also has the distinct red fang markings of the Inuzuka clan on his cheeks.
