Sakon had a malicious, mocking, and extremely self-confident nature, constantly provoking enemies and enjoying prolonged battles. He was proud that Orochimaru and Kabuto considered him the fastest and strongest in the Sound Four, and never missed an opportunity to prove it in battle. He referred to opponents exclusively as "trash" and sincerely believed that with Tayuya's help he could defeat even Kakashi. He had the worst personality in the group: he never stopped until he killed his target. At the same time, Sakon acknowledged the seniority of his brother Ukon and obeyed his orders, although he usually acted as the main body. He treated his comrades with the same rudeness, but maintained the appearance of subordination. Any display of weakness only evoked his contempt and a desire to mock.
