Background
Thirty years before the start of the Fourth Shinobi World War, he was killed by the Eight-Tails during one of its scuffles, being impaled by one of its horns. His death strained the friendly relationship between his son and Killer B when the latter became the new jinchūriki of the Eight-Tails.

Personality
In the anime where his personality is expounded on, he was shown to be a very brave individual who loved his village greatly rallying the rest of his team-mates to continue restraining the beast, since if they gave up, Kumogakure would be destroyed.

Appearance
He was a tall man with dark spiky hair. He wore round glasses, the standard Kumogakure flak jacket, a forehead protector, and shin guards. In all, he and his son bear great resemblance.

Abilities
He was skilled enough to have been selected by the Third Raikage as part of a special team that subdued the former jinchūriki whenever it lost control of the beast and went on a rampage. He was seen using a chain with a weight on the end as his weapon to hold down the beast. The anime expounds on his abilities, revealing that he could use Lightning Release techniques such as the Lightning Release: Wave of Inspiration technique with such skill that he was able to temporarily stop the beast's movements allowing his team-mates to move in an help subdue the beast.
