Giru

Giru is the dinosaur Greeed. He has aspects of a pteranodon, a triceratops, & a tyrannosaurus. Unlike the other Greeed, he was never seen & only physically appeared as ten Core Medals that were kept under lock & key by the Albert Foundation, before they were stolen by Kieran Leach. These Core Medals proved to still house some form of consciousness, however, & sought out Ethan because of his lack of desire.

Abilities
As a Greeed, Giru has the ability to create Yummies by placing a Cell Medal into a '''Medal Insert Slot. '''Instead of using humans to make Yummies, his are made using inanimate objects that represent the end of a desire, such as broken dreams. As his abilities lie in destroying desire, half of his Core Medals go to Ethan because of his lack of selfish desire. The medals, at first, forced him into a berserker state whenever he would use them to assume Kamen Rider: OOO Invincible Combo. It could have been possible that he could assume a human form, as all Greeed can, as well as travel distances by dispersing into a mass of Cell & Core Medals.
