Kitane

Kitane was once a member of the 12 Ninja Guards of Fire. He was killed ten years prior to the start of the current storyline, fighting against the members of the attempted coup d'etat. He appears to have once been friends with Asuma Sarutobi before his death.

Background
While he was still alive he was part of the 12 Guard Ninjas of Fire. When six of the members tried a coup d'etat he alongside Asuma Sarutobi, Chikiru, Nauma, Tou'u, and Seito fought against them, only to be killed by Kazuma when Kitane and the three later of the 12 Ninja Guards tried to use Limelight on him.

Fire Temple Filler Arc
During the begining of the filler arc is his, Nauma's, Tou'us, and Seito's corpses stolen by graverobers, and later revived using lightning. After beeing revived they were all four approached by Asuma who had figured out the scheme of the robers. There he tries without luck to stop the later three who seems to have become mindless puppets, while Kitane, the only one of them who still seem to think clearly, attacks Asuma, saying that he cannot go against his summoners orders.

Abilities
He along with Nauma, Tou'u, and Seito had an affinity for lightning. He used a three parted metal staff to fight with, that is also able to conduct his lightning based attacks. Kitane could send lightning through the ground to attack by striking his staff into the ground. When separating his staff into three pieces he can use his jutsu Lightning Release: Thunder Binding to form a barrier around a target. When in the four cardinal directions Kitane, Nauma, Tou'u, and Seito could use a jutsu called Limelight to destroy everything within that area to ash.
