Third Mizukage

The was the leader of Kirigakure.

Background
Before becoming the Third Mizukage, he accompanied the First Mizukage to the first ever Five Kage Summit during the First Shinobi World War. There he stood behind the First watching diligently as the proceedings unfolded.

Appearance
He was a tall man with black sclera, no visible pupils, and long, black hair which was long enough to reach his back with what appears to be pearl-shaped objects forming a circular pattern in his hair. He wore the standard Kirigakure attire complete with pinstriped arm and leg-guards over which he wore a sleeveless haori with ragged ends. He also wore a poncho-like scarf around his neck. At the time of his death, he had aged considerably, with notable creases and visible frown lines around his mouth, and much lighter hair.

Abilities
Though the Third Mizukage's abilities remain mostly unknown, the fact that he was chosen as the Kage of his village, suggests that he was most likely a powerful shinobi. Even before becoming the Mizukage, his power was such that he was chosen to be the bodyguard of the First Mizukage.

Kaguya Ōtsutsuki Strikes
Subsequent to Kaguya Ōtsutsuki being sealed by Naruto Uzumaki and Sasuke Uchiha, he and the other deceased Kage were summoned from the Pure Land by Hagoromo Ōtsutsuki to aid him and the Hokage in summoning Team 7, the tailed beasts, and Madara Uchiha from Kaguya's dimension. Later, his and the other Kage's souls were returned to the Pure Land.
