Ōnoki

is the current, and the leader of Iwagakure. He is called.

Appearance
Ōnoki is an old man with a size of one and half times his head piece. His facial features include a triangular beard and a moustache with angular corners.

Personality
He is very proud but appears frail, with constant complaints referring to his hips and back. Kurotsuchi describes him as a "stubborn old man." Onoki also seems to have very little respect for those younger than him, verbally attacking Gaara, who is many years younger, on numerous occasions. He also seems to be quite ruthless, taking down an heavily-injured Sasuke who barely escaped the wrath of two other Kage before him, and then immediately turning his attention to Karin, whom he claims to be next after Sasuke.

Five Kage Summit arc
He was first seen preparing for travelling to the meeting of the five Kage, and received a bid from his village to return safely and, at the same time, display to the other Kage how powerful the one from Iwagakure stands out, accompanied by an incredibly large young fellow named Akatsuchi as well a young kunoichi named Kurotsuchi, the latter who even suggested that he should retire soon.

Albeit complaining about his hip, he still wanted to carry his own bag, and ranted about being the Tsuchikage, only to hurt his back when he put on his backpack. Akatsuchi had to carry him all the way to the summit.

Later, while resting, Ōnoki tells Kurotsuchi and Akatsuchi about the Land of Iron, where the meeting is to be held. Upon arrival Ōnoki presents his Kage hat that denotes his position as Tsuchikage. He was seen with a rather apprehensive look on his face as it begins.

Once the Five-Kage meeting began, he acted as the skeptic, saying that Kumogakure should deal with its own problems, and that a country whose host has been taken has no right to give orders, speaking to both the Raikage and Gaara. He then explains how Akatsuki became useful to the ninja villages, who had reached a time of peace and demilitarization, but fear of an approaching conflict would lead them to depend on mercenaries; saying that building up a force for defense would take time, that Akatsuki didn't cost much, and that they were very effective in producing positive results. After being interrupted by Raikage, he listens as Mifune offers a proposal for an alliance, but is shocked and angered when the Hokage is proposed to be the leader of such an alliance. Mifune later says that Onoki cannot be the leader of the alliance because in contrast to Gaara, he is far too old and that he has used Akatsuki far too many times so he can't be trusted. When the Raikage goes to find Sasuke he comments on how the Raikage has always been hotheaded and headstrong ever since he was a boy. He is also against trusting Danzo and considers Gaara to be too young to talk at the conference.

When Gaara, the Raikage and their bodyguards leave to stop Sasuke's advance, Ōnoki and Akatsuchi are left with Danzo and the Mizukage, alongside their respective bodyguards. As Sasuke reaches the meeting room, and the Mizukage prepares to do battle with him, Ōnoki decides that his hips are acting up too much for him to take part in the battle. He and Akatsuchi have thus taken a neutral standpoint. As the Mizukage and her last remaining bodyguard do battle with Sasuke, Ōnoki is, like every other ninja in the room, attacked by Zetsu's technique. After witnessing Sasuke escape from his battle with the Mizukage, he muses that she may need some help, so he joins the battle. Ōnoki performs Doton Kajugan no Jutsu, causing the Zetsu binding him to transform into a rock-like material, crumbling off of him. He attacks Sasuke with Jinton Genkai Hakuri no Jutsu and smashes Sasuke into the floor with a large cube. As Gaara and Raikage arrive, asking for Sasuke's location, Ōnoki states that he has smashed him to smithereens. However, seconds later Sasuke is revealed to be alive, having been saved by Uchiha Madara.

Abilities
Ōnoki's Dust Release ninjutsu allow him to pulverise his enemies to molecule-sized dust. He is also skilled with Earth Release ninjutsu and has shown the ability to levitate.
