Oonoki

オオノキ

Oonoki is the current Tsuchikage of Iwagakure.
In his youth, Oonoki was a student of the Second Tsuchikage, Muu, who taught him how to use Dust Release techniques. Later in life, he became Deidara's teacher. Although he often implied that Deidara's ideologies and fighting style annoyed him, he remained proud of him. At some point in the past, Oonoki fought Madara Uchiha, making him the only living Kage to do so. His knowledge of Madara's power made him wary, so he was surprised that the latter chose to carry out his designs behind the scenes through Akatsuki. Probably unaware of Madara's major role as Akatsuki's founder, he hired the former mercenary group many times for their services in the past, rationalizing this by his concern over Kumogakure's unwavering militarization. He has also apparently known and dealt with A, the Fourth Raikage, since the latter was young.
Oonoki is very proud but appears frail, with constant complaints about his hips and back. He also refuses to retire and choose a successor as Tsuchikage despite his frailty, insisting that he is still strong enough to continue ruling the village. Kurotsuchi describes him as a "stubborn old man". His pride leads him to give very little respect to those younger than him; he verbally attacked Gaara (a Kazekage many years younger) on numerous occasions, dismissing his presumed naivety in dealing with politics. Deidara also noted that Oonoki hates art, possibly because he ridiculed his Exploding Clay artwork. During the chaos Sasuke Uchiha started, Oonoki did not seem alarmed once the battle in the Summit Room began. He appeared calm enough to let Mei Terumī deal with the current situation. Upon observing the fight between the two, he seemed quite entertained, which led him to join the riot.
Oonoki seems quite ruthless, taking down a heavily injured Sasuke who had just been saved yet again after facing the wrath of three other Kage before him, on the claim that the Ninja World wants Sasuke dead, even though Oonoki himself holds no personal grudge against Sasuke. He then immediately turned his attention to a devastated Karin, claiming that she is next to die. However, he does seem considerate enough to let Madara speak for his actions, reasoning with the Raikage to listen to his reasons before making their own. According to his strategic thinking, Oonoki might be the type of person who takes risks. A similarity can be seen with Tsunade, as she has a habit of gambling and taking risks often. Remembering what Gaara said to him, he states to Akatsuchi and Kurotsuchi that he remembered what he really used to be before he became a stubborn old man, likely meaning he had a more kind and friendly heart in his youth.
Oonoki is a powerful and capable Tsuchikage. He is physically frail, however, and as such he is not suited for taijutsu fighting. He has a great deal of experience, having fought Madara Uchiha and survived, thus his knowledge is invaluable to the Allied Shinobi Forces.
Nature Transformation
Oonoki possesses the ability to use the Kekkei Tōta known as Dust Release, by combining three elements, such as Earth, Wind, and Fire. He is only the second shinobi in existence with this ability. Oonoki's dust release ninjutsu allow him to pulverize his enemies to molecule-sized dust. His techniques can be so destructive that they are reputedly capable of destroying an entire island.[4] His Earth Release ninjutsu is particularly powerful, and could turn targets into stone by a mere touch.
Flight Technique
Another one of Oonoki's trademark techniques is his ability to fly, which he is also capable of transferring to others. He can fly at very high speeds even in his old age. Size also does not seem to matter when using the technique, as he used it on the Island Turtle, carrying it in the air to Kumogakure.
