Sharingan
Due to his early battles with an Uchiha, Aoitsuchi has a eye in his right eye socket. To keep it from taking up too much of his chakra, Ōnoki, his father, place a seal upon his chest which limits the chakra consumption of Aoitsuchi's Sharingan. This has two known effects on the dōjutsu. One, it causes the three tomoe to become three dots instead, making it look peculiar among other Sharingan, and two, it prevents Aoitsuchi from every awakening the Mangekyō Sharingan. Aoitsuchi can activate and deactivate his Sharingan due to the seal, something that most transplanted Sharingan are incapable of doing. This allows him to keep his secret hidden until he needs to use it. Other than these abnormalities, his Sharingan is just like any other. It allows him to see the color of chakra, copy non-kekkei genkai jutsu (a trait he claims to seldom use), and cast on those unlucky enough to make eye contact with it.
