Akatsuchi

is a large shinobi of Iwagakure and a bodyguard of Ōnoki.

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

When the Raikage destroyed his table during the meeting, Akatsuchi was seen moving to attack in defense of his lord, but was soon dismissed by the Tsuchikage. 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 the Mizukage deal with him. Later, he is ensnared in Zetsu's Hoshi no Jutsu. Seeing Sasuke escape the Mizukage, 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.

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.

Trivia

 * The name, means "Red Earth", is a possible allusion to Ancient Egypt; most of Ancient Egypt was comprised of desert, which was known to the as "Dashret", which means the "Red Land" or "Red Earth", and where the word desert comes from.  Also, Akatsuchi's fellow bodyguard, his partner, Kurotsuchi's name means "Black Earth", is another possible allusion towards Ancient Egypt; the land on either side of the River Nile was known as "Kemet", which means the "Black Earth" or "Black Land", so named for the dark-colored silt that was deposited on the banks of the River Nile when the river would flood before the Aswan Dam was built.
