One of Kamen Rider OOO's final combos, accessed via the Ptera, Tricera, and Tyranno Core Medals.
It is easily one of the most powerful Combos in OOO's arsenal, but it will slowly turn him into a mindless beast if he stays in the Combo for too long until recently when Kamen Rider OOO managed to gain control of the Purple Cores (if barely), 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 undergoing a process known as "Greeedification", gradually turning him into a Greeed the longer the Medals are inside him. PuToTyra has a power that is capable of destroying or damaging Core Medals. After Eiji gains two more Purple Medals, he can access this form in the usual way or can transform straight into Putotyra while in Greeed form.
Unlike the other combos, Putotyra causes most of the OOO armor to become white and cannot form a Random Combo with the other Core Medals, as the purple Medals are made in nature as the antithesis of desire, negating the power of the other Core Medals. The O Scanner announces this Combo by the call "PuToTyrannosaurus" instead of "PuToTyra".
Putotyra's flight speed is faster than TaJaDor, has greater jumping height, and its punching and kicking powers are stronger than the other Combos, making the "Invincible Combo" nickname a well-deserved one.
OOO can now use the wings on the Ptera Head, called External Fins, to fly, as well as to freeze the opponent with a blast of icy air; the horns on the Tricera Shoulders, called the Wind Stinger, which can stretch into various lengths according to Eiji's command; and the Tyranno Legs' thigh armor can combine to form a tail, called the Tail Divider, that can give off a devastating blow.
Also, like Tajador, this Combo has its own weapon, an axe called the Medagabryu that also doubles as a bazooka, enabling OOO to unleash the full potential of the Purple Core Medals. The Medagabryu can draw out the full potential of the Cell Medals, by inserting a number of Cell Medals into the "mouth". Doing so in any Combo other than Putotyra will make it announce a Combo and a jingle remix, except for the TaJaDor Combo. When Cell Medals are inserted in the Medagabryu when in the Putotyra Combo, OOO can perform a Putotyranno Hissatsu depending on the weapon's mode. When in Axe Mode, OOO can perform the Ground of Rage or the Strain Doom when in Bazooka Mode.
His Scanning Charge is the Blasting Freezer, where OOO uses his Tricera Shoulders' Wind Stingers to stab his opponents in the shoulders to hold them in place, while he uses his Ptera Head's External Fins to freeze them immediately after, and the Tyranno Leg's Tail Divider to finish them off by smashing them into frozen shards.
