Ōnoki

Ōnoki was a very short, old man with a triangular beard and a moustache that had angular corners, a big red nose and thick eyebrows. The top of his head was completely bald, although, he had long white hair on the lower-half of his head which is styled in a traditional chonmage hair cut, the back of which was tied with a yellow ribbon into a topknot. Ōnoki wore a split apart green coat divided into four sections with yellow trimmings, and a red collar (which in the anime was seen to be worn by other high-ranking members of Iwagakure). Underneath he wore the traditional Iwagakure outfit consistent of a light green version of Iwagakure's flak jacket and mesh armour. He however had both his sleeves of his shirt, but kept the single lapel on his right side. Along with this, he wore sandals. During the tenure of the First Tsuchikage, as an adolescent, Ōnoki had brown hair along with dark brown and thick eyebrows. He also wore a dark brown T-shirt and beige pants with black shinobi sandals. When he was a young adult, Ōnoki wore an outfit with armour plating on it and his forehead protector on his head like a bandanna. Some time after retiring as Tsuchikage, Ōnoki's hairline receded even further, with his advanced age showing in the form of liver spots and more wrinkles. His eyes had also become heavy-lidded and he had grown a longer moustache and beard.

When he was an adolescent, Ōnoki was tasked with cleaning his village's Stone Monument. As he did so, his grandfather, the First Tsuchikage, came and spoke with him. Ōnoki, who believed that the First was just a cheap old man to have such a simple thing as the symbol of the village, was then told that the stone represented the unmovable will of the shinobi of the village. The First then told Ōnoki that he too possessed that strong will, but would lose it if he didn't face adversities with determination. As a young man, Ōnoki was a student to the Second Tsuchikage, Mū who passed down to him the secrets of Dust Release techniques. At some point, Ōnoki fought with Madara Uchiha, and was the only living Kage to do so before Madara's death. On one occasion, Madara approached them and declared that despite the alliance between their villages Konoha was to remain the dominant one and anything that Konohagakure requested, Iwagakure was to obey. His knowledge of Madara's power made him wary of him, and was thus surprised that the masked man could really be him. He had also encountered the Second Mizukage, his mentor's rival, and was constantly picked on by the latter. Eventually, Ōnoki succeeded Mū for the title of Tsuchikage. During his reign, in the anime, he endured the hardships of the Third Shinobi World War, watching many of his people die in battle. Eventually, Konohagakure offered a peace treaty from the Third Hokage himself. While the Iwa council was against the treaty, Ōnoki strongly considered accepting it to stop the bloodshed. At some point, he became acquainted with Deidara, becoming familiar with his ideologies and fighting style. As Tsuchikage, he hired Akatsuki many times for their services in the past, which he rationalised by his concern over Kumogakure's unwavering militarisation. He has also apparently known and dealt with the Fourth Raikage since he was young. Later in the anime, Ōnoki received an invitation from Konohagakure and Sunagakure to join an impromptu Chūnin Exams they would be hosting together. Arrogantly thinking this was an attempt by the two villages to better gauge Iwagakure's strength for an upcoming fight, Ōnoki quickly turned down the offer, merely replying to the hosts that his village was too busy.
