Greeed

The Greeed are strange animal-like kaijin and along with their subordinates the Yummy they are the leading villains of Kamen Rider OOO. Their name is taken from the English word Greed.

Overview
The Greeed (グリード, Gurīdo?) are strange monsters who appear on the Earth after having hibernated for 800 years. Each of the five Greeed seek to become the predestined Multi King (複数の王, Fukusū no Ō?) by gathering the Medals (メダル, Medaru?) of their rivals. To compete with each other, each Greeed is able to create monsters called Yummy by using their Medals on human desires something. Ankh is a member of this group and is the bird Greeed, but due to having lost several of his Medals he can only manifest as his forearm, and uses Kamen Rider OOO to help him become the Multi King. Likewise, Anku managed to steal several Medals from each of the other Greeed, which he gave to OOO, rendering them incomplete. As the body of the Greeed of Core and Cell Medals, they are much stronger and not based on a single Medal, unlike their subordinates.
