Ankh (アンク, Anku) is the deuteragonist of Kamen Rider OOO. He is a Greeed and supporter to Eiji Hino who possessed Shingo Izumi (泉 信吾, Izumi Shingo) in his crusade against the four other Greeed. After defeating his splintered counterpart and regaining his body, a final confrontation with the Eiji Greeed and Kiyoto Maki led to his primary Core Medal being split in half, but his consciousness otherwise remained intact. He was resurrected ten years later and possessed Eiji to become the current Kamen Rider OOO (仮面ライダーOOOオーズ, Kamen Raidā Ōzu) himself.
