Akatsuchi

is a large shinobi of Iwagakure and a bodyguard of Ōnoki, the Third Tsuchikage.

Five Kage Summit arc
He was setting off with Kurotsuchi to escort the Third Tsuchikage to the Five Kage meeting, called for by Ē, the Fourth Raikage. When Ōnoki hurt his hips when trying to carry his bag by himself, Akatsuchi carried him along the way.

When Ē destroyed his table during the meeting, Akatsuchi was seen moving to attack in defense of his lord, but was soon dismissed by Ōnoki. When White Zetsu appears during the summit, Akatsuchi and Kurotsuchi guard the Tsuchikage. Later, when Sasuke infiltrates the meeting room, Akatsuchi and Ōnoki decided not to engage him, moving out of the way to let Mei Terumī, the Fifth Mizukage, deal with him. Later, he is ensnared in Zetsu's Spore Technique. Seeing Sasuke escape Mei, Ōnoki suggests to two of them join the fight. Akatsuchi agrees, and uses an unnamed technique to expel a large rock golem from his mouth. This golem bites and pulls Zetsu from Akatsuchi's body.

After Madara told the story of the Ten-Tailed Beast and the Sage of the Six Paths, then declared the Fourth Great Shinobi World War, Akatsuchi left with the Tsuchikage and Kurotsuchi to unknown locations.

Abilities
Though he has not been shown very much in battle, during Zetsu's assault, Akatsuchi has displayed the ability to expel a large rock golem from his mouth. This golem has great strength, capable of biting off Spore Zetsu's head, and pulling him from Akatsuchi's body.
