Kibakage

The Kibakage (牙影; Literally meaning 'Fang Shadow') is the strongest shinobi of Sōsōgakure as well as the leader of said village. Like the Raikage of Kumogakure, the Kibakage must also have a partner to fight alongside with. Also to become the next Kibakage, you must defeat predecessor and his partner in a two on two match.

First Kibakage
Kinguraion Yaban became the first Kibakage after founding the village in the Land of Predators alongside his partner Suterusu.
