Gaou (牙王, Gaō) was a member of Team Rokuyukai during the Dark Tournament. After Zeru is killed by Hiei, he and Imajin get scared and run away, leaving the rest of the matches to Rinku. However, as they flee, they run into their leader Chū who kills them for such a cowardly disgraceful act. In the manga however, Chū beheads them just before they could run.
He is voiced by Phillip Wilburn in the English version.
Gaou is a tall, muscular man who is even taller than Zeru. He wears a short sleeved green shirt with brown pants and black boots. He has a dark skin tone, as well as short black hair.
