PuToTyra Combo

Putotyra Combo is Kamen Rider OOO's purple combination using the powers of the purple Core Medals that forced themselves into Eiji's body: Ptera, Toricera, and Tyranno. Though it is the most powerful form that Kamen Rider OOO can assume, it originally turns Eiji into a mindless beast if he stays in the Combo for too long. He eventually manages to exert his will over the purple Core Medals, but he still suffers from the physical strain resulting from Combo use, and is still at risk of "letting himself go" if he does not consciously keep control. As a result of the purple Medals residing in his body, Eiji is gradually turning into a Greeed the longer the Medals are inside him. After Eiji gains two more Purple Medals, he can access this from in the usual way. He can freeze opponents with a cold wind, use the wing-like External Fins on the Ptera Head to fly, use the Wind Stingers that can extend and attack the enemy from far areas, and is armed with the Tail Divider that can deliver a powerful blow and the Legsteranail claws for powerful kicks. In addition, he is armed with the Medagabryu. Unlike other Combos, the OOO Armor becomes white and cannot mix-and-match with other Medals, due to their Medals' nature as the antithesis of desire negating the power of the other Core Medals.
