Ryosuke Miura

Ankh is the bird Greeed, an anti-hero throughout the series. Unlike his fellow Greeed, he is an ally to the protagonist Kamen Rider OOO, mainly because of his inability to assume his full form and his lack of trust towards the other Greeed. However, when he regains his physical form, Ankh becomes OOO's enemy. It has been revealed that his Core Medals are: Taka (Hawk), Kujaku (Peacock), and Condol (Condor).


Ankh is a dishonest wildcard. As a Greeed he has little regard for humans, seeing them for their flaws, with Eiji being one of the few exceptions. Ankh also believes that he has the right to get whatever he wants and detests having to give something away if there's no benefit for him. He is also at odds with the other Greeed, both because of the history he had with them, as well as stealing their Core Medals. He focuses only on obtaining enough Cell Medals to regain his body and to become Multi King. He has however been shown to repay debts to people, giving Eiji the means to become OOO, though this mainly because he wanted to use Eiji as a tool in his quest. Though Eiji plays him at times, Ankh prefers working with Eiji over with his fellow Greed as the human is honest about his motives. He had since underwent a personality change, where he can no longer bring himself to harm Eiji or Hina without substantial reasons.

Ankh 2

Ankh's real form

He serves Eiji as his companion and his Medal Manager, supplying him with Core Medals stolen from other Greed. Since possessing a human body, Ankh has been able to experience real emotions and the full effect of the five senses, something a Greeed is normally not capable of unless it possesses all nine of its Core Medals. The most prominent example of this effect is his ability to taste food, resulting in him developing a strong liking for popsicles to the extent of taking them without second thought such as taking them from a cart and making Eiji pay and scaring off children. Ankh also shows a preference for high places, frequently shown on trees, resting somewhere high in his quarters shared with Eiji, and jumping out of the window instead of going out through the door. Ankh avoids eating poultry due to his connection to birds.

He is also commonly seen carrying an iPad or an iPhone 4 for gathering information and keeping track of the Core Medals. He is however not above betraying Eiji for his own benefit, whether it be regaining one of his Core Medals or joining the other Greeed to get new power while betraying the Greeed in a well formulated plan. Ankh's faith in this plan is so strong, he is willing to give the other Greeed all their Core Medals back unconditionally, a result of being spoiled by his experiences with human senses, which in turn fueled his growing disgust with his fellow Greeed.
