Dosu Kinuta was a wary and judicious shinobi who never acted rashly, preferring to think things through first. He was distinguished by his composure and rarely gave in to emotions in battle. He treated his village and the mission entrusted to him by Orochimaru with fanatical devotion. When Kabuto spoke disparagingly of the Village Hidden in Sound, Dosu immediately attacked him. At the same time, he was polite enough to apologize to Ibiki when there was a threat of failing the exam. Despite claims that Sound shinobi are willing to sacrifice comrades, he sincerely promised to avenge Zaku. At first, he zealously followed the order to kill Sasuke Uchiha, but everything changed when he learned about the Cursed Seal. Realizing that their entire team was merely a disposable pawn to test Sasuke, he grew bitter toward Orochimaru and planned to thwart his plans. His loyalty instantly turned into cold hatred, and he decided to personally kill Sasuke to spite his former master. It was this obsession that drove him to the reckless act of attacking Gaara alone. In everyday life, he was described as courteous and reliable, although a ruthless nature was hidden beneath the bandages. He respected strong opponents but was merciless toward the weak, believing that effort alone was not enough. He regarded his sound technique as an absolute weapon that could not be opposed. His self-confidence was based on precise calculation, but in the face of overwhelming power, he proved just as helpless as his victims.
