Kiba Inuzuka, the fierce ninja, sports reddish-brown eyes with sharp, vertical pupils and shaggy brown hair. Young and athletic, he carries himself with a confident, almost arrogant swagger. He's impulsive and competitive, often outspoken, but fiercely loyal to his pack, especially Akamaru. While not outwardly goofy, his brashness and unwavering belief in his own strength can be amusing. He's energetic in his movements, driven by a desire to prove his power and protect those he considers his.
