Akatsuchi

In the anime, Akatsuchi was present during a council meeting to discuss an invitation from Konohagakure and Sunagakure to join an impromptu Chūnin Exams they would be hosting together. As Ōnoki arrogantly believed this was an attempt by the two villages to better gauge Iwagakure's strength for an upcoming fight, Akatsuchi simply suggested they just turn down the offer, to which Ōnoki firmly agreed.

Akatsuchi is a very jovial individual who always seems to have a cheerful disposition. He is also somewhat childish and laid-back, witnessed through his excitement at the prospect of flying once again, even though there was the possibility that they were going off into a battle. He was even excited when he thought Deidara survived the battle against Sasuke Uchiha, despite Deidara being a criminal and their enemy. During battles, however, he is level-headed and efficient as the Tsuchikage's bodyguard. He is also fiercely loyal to the Tsuchikage, and refused to leave his side when he heard of Sasuke's fight, just in case Ōnoki's hip went out. Deidara also attested to the fact that Akatsuchi rarely ever leaves Ōnoki's side when he fought the two.

Akatsuchi is a large and imposing man, with dark eyes and black hair that spikes out at the back from underneath his bandanna-styled forehead protector. He also has large cheeks, and a plump nose which give him an overall look of constant joviality. He wears the red Iwagakure uniform which has both its sleeves, underneath his flak jacket, and accentuates it with a yellow scarf which he wraps around his neck. In later years after the Fourth Shinobi World War, Akatsuchi grows a beard and seemingly discards his forehead protector and retains his yellow scarf. He also ties his hair in a ponytail and he has apparently trimmed down somewhat as his cheeks became less plump. He wears a brown kimono and pants.

As a jōnin, he is likely a formidable shinobi. With his credibility, he was chosen to guard not only the Third Tsuchikage, but the Fourth Tsuchikage as well, during their respective meetings at the Kage Summit.

Akatsuchi is able to use the Earth Release nature transformation. With it, he displayed the ability to mould and expel a large rock golem from his mouth, capable of tearing through a White Zetsu clone's head. The golem can also be used to shield himself and allies from an opponent's attack. He can also condense the earth near him around a target's feet to immobilise and trap them.

Akatsuchi has been noted to possess unrivalled physical strength in his village. As such, he was capable of effortlessly carrying the Tsuchikage and both of each other's luggage for an extended period of time. Despite what his size entails, he is quite fast, as seen when he rushed to the Tsuchikage's side after reacting to the Fourth Raikage's aggressive action. He also shows noticeable stealth skills, tailing multiple genin for hours without them noticing while still gathering intel on them.
