Ankh
Ankh (アンク, Anku?) is the bird-type Greeed, a dishonest wildcard who sees people for their flaws and is at odds with the other Greeed. Ankh also believes that he has the right to get whatever he wants and detests having to give something away. Eight centuries ago, Ankh conspired with the original OOO and battle the rest of the Greeed before being betrayed by OOO when all the other Greeed were defeated. He was impaled by OOO's Tora Claws, having his Core Medals stolen. When the original OOO attempted to absorb all the Medals' power, it resulted in the Greeed being sealed away, including Ankh. However, Ankh's right forearm, holding the Core Medal containing his consciousness, was severed in the process and sealed with the other Greeed while his mindless body, mummified and dormant, ended up in Europe. As a result, he lost most of his powers. When the Greeed were unsealed, Ankh was only able to manifest back into existence as his right forearm and stole some of the other Greeed's Core Medals to have them handicapped. However, he loses one of his two remaining Taka Medals when Eiji takes it by accident. Ankh originally intends to force Eiji to return his Medal, only to be saved by Eiji from the Kamakiri Yummy sent after him. In a dire need to see that both of them survive the Yummy attack, and intending to make Eiji a pawn in his scheme (as he can not create a Yummy in his condition), Ankh saves the human by lending him the OOO Driver and some of the Core Medals he has, enabling Eiji to transform into Kamen Rider OOO.
After the Yummy is destroyed, Ankh takes the body of the half-dead detective Shingo Izumi as a temporary host to move around, causing the human's hair to develop a peculiar style with a dull blonde color. Ankh can remove himself from Shingo's body on occasion, though he must reattach himself within ten minutes to keep Shingo alive. Ankh eventually finds himself compromising his original plan (having underestimated Eiji's strength of will), reluctantly cooperating with Eiji to save human lives on the condition that Eiji continues gathering Cell Medals as Kamen Rider OOO. Though Eiji plays him at times and is constantly at odds with him, Ankh still prefers working with Eiji over his fellow Greeed, as the human is honest about his motives. 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 even when completed. As a result, Ankh grows to desire the life that humans were blessed with that Greeed can never have. The most prominent example of this effect is his ability to taste food, resulting in him developing a strong liking for popsicles. Typical of birds, 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. Ankh is sometimes seen carrying an iPad or an iPhone 4 (which Shingo had bought) to gather information on the current era as well as to keep track of the ownership of the Core Medals. He also receives a gift from Hina in the form of the O Medal Holder to place his Core Medals in. Overtime, he begins to undergo a change in personality, ultimately finding himself no longer able to bring himself to harm Hina and Eiji without substantial reasons.
Even though he managed to regain some of his Core Medals, Ankh is unable to regenerate any other parts of his body. The mystery behind both that and why Ankh cannot produce Yummy is revealed when the rest of his body appears. Ankh eventually reveals to Eiji, Hina, and Date the mysteries behind OOO and the Greeed and his resulting condition from that fight. Furthermore, due to his interaction with Ankh (Lost), Ankh's hold over Shingo wavers as the man's sufficient recovery over time would eventually prevent the Greeed from using his body. Eventually, Ankh is absorbed by his other self, yet their fusion is incomplete as he attempts to defy Ankh (Lost) and passed a Taka Medal to Hina before being absorbed. After Kamen Rider OOO manages to destroy Ankh (Lost) along with a full set of Ankh's Medals, the original Ankh managed to use Ankh (Lost)'s remains to reform his body and model his human form after Shingo's possessed state. However, Ankh's weakened state is unable to maintain a complete body, so he mortally wounds Shingo again and reduced himself to his original disembodied arm to take control of the detective's body once more. Having regained his full powers as a Greeed and taking back his Taka Medal from Eiji, Ankh offers to help Maki in gaining Eiji's purple Core Medals in return for becoming the vessel for all the other Core Medals. Reviving Uva, Ankh then joins forces with the other Greeed and rallies them against Eiji. However, counting on Eiji's new-found ability to destroy Core Medals, Ankh formulates a reckless plan to have OOO eliminate the other completed Greeed so he can use their Core Medals to fully fuse Shingo's body with his mind, thus gaining true conscious life.
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. When he is forced into fighting the Eiji Greeed, Ankh transforms into his Greeed form, referred to as Ankh (Greeed) (アンク（グリード態）, Anku (Gurīdo-tai)?). However, due to the time he had with Eiji and his newfound capacity for feeling deeper emotions, Ankh is unable to kill him and turns on Maki, eventually resulting in the Taka Medal containing Ankh's consciousness being cracked (placing his "life" in jeopardy) and most of the Core Medals he had being taken by Maki. But though he knows that he would die, Ankh felt at peace about his eventual fate and peculiarly, felt satisfaction for the first time, something a Greeed is inherently incapable of feeling. In the final battle, Ankh joins Eiji in fighting Doctor Maki as his Greeed Form while Eiji fights as Putotyra Combo. When the Kyouryu Greeed manages to negate Putotyra Combo, Ankh gives Eiji his last three Core Medals to prevent him from going rampage with his purple Core powers, disappearing and allowing Eiji to assume Tajadol Combo. His spirit fights alongside Eiji against the Kyouryu Greeed as they defeat Doctor Maki and destroy all of the other Core Medals. As Eiji falls back to earth, Ankh appears to him as his disembodied arm. Thanking Eiji for him and the others enabling an artificial being like him "to live", and to die a human's death, Ankh says his farewells before disappearing into half of the broken Taka Medal that once held his consciousness, while the other half appears to Hina in a brief manifestation of his Shingo-like body. As Eiji leaves on his journeys around the world, he keeps both halves of the broken Core Medal with him with the hope to somehow revive Ankh. In the events of Mega Max, Eiji learns that he somehow found a way as Ankh arrives from the future to help him with Kamen Rider Poseidon.
The name "Ankh" comes from the Hindi word for "eye" (आँख ā̃ṅkh), as in a hawk's eye. His name was originally planned to be "Ash" (アッシュ, Asshu?) from the Japanese word assuru (圧する?, "to oppress" or "to dominate").
Ankh is both voiced and portrayed by Ryosuke Miura (三浦 涼介, Miura Ryōsuke?). Miura previously portrayed the Beetle Sazer Kane Lucano in Chousei Kantai Sazer-X, and also had a guest appearance as the Tiger Orphnoch Momose in Kamen Rider Decade.
