Yagura Karatachi

was the jinchūriki of the Three-Tailed Giant Turtle and the of Kirigakure. When the Three-Tails was captured by Akatsuki, it had no host and roamed out in the wild.

Background
During his time as Mizukage, the village was known as the, mostly because of the barbaric ritual where Academy students kill one another in order to graduate. This practice was discontinued when an entire graduating batch of Academy students were massacred by a young Zabuza Momochi. It is likely that Yagura was the Mizukage whom Zabuza tried to assassinate when he revolted.

Yagura was also known to dispatch Kiri-nin who were suspected of being disloyal to the village immediately (commending and taking Kisame Hoshigaki as his direct subordinate after assassinating Fuguki Suikazan, a traitorous member of the Seven Ninja Swordsmen of the Mist). Yet despite the terror of his reign, he appeared to be kind. Apparently the people of Kiri feared that Yagura was being manipulated, a fear which was confirmed by Ao, who saw through an unnamed genjutsu with his Byakugan, later identified by Kisame as the work of Madara Uchiha.

Appearance
Yagura has messy gray hair, pink pupiless eyes and what seems to be a stitch-like scar running from under his left eye all the way down his cheek. He has a dull expression and wears a gray undershirt with short mesh sleeves which has a metal plate of a Kirigakure forehead protector sewn onto it over which he also wears a green poncho, a turquoise sash around his waist, paired with a green indument over his pants. He wears a pair of brown boots opened on the back, and on his back he carries a staff-like pole weapon with uneven hooks with a green flower on the end of the larger hook.

Abilities
Not much is known about his abilities except that he was presumed to be a powerful shinobi due to him being chosen as the Mizukage, and was also one of the few jinchūriki that were able to fully control their tailed beast. He wielded what seems to be a large staff, with two hooks on each end, one larger than the other, along with a flower on the larger end.

Shinobi World War Arc
He is resurrected by Kabuto, along with the other deceased jinchūriki through the Summoning: Impure World Resurrection, to fight in the Fourth Great Shinobi World War.
