The Yummies (ヤミー Yamī) are the underlings to the Greeed serving as secondary antagonists in Kamen Rider OOO.


The Yummy are monsters created by the Greeed and serve as their subordinates when a Cell Medal is used on a human. Each Greeed has a different method of producing a Yummy relative to the birth (or maturing process in Uva's case) of the type of animal: Uva's start off as a humanoid Shiro Yummy until it molts into more powerful form, Kazari's also start off as Shiro Yummies but his are parastic to the host, Mezool's begin as a roe-like substance and generate smaller clones, Gamel's can born them directly from the Greeed with a Cell Medal but being passive himself, and the Lost Ankh's start as a giant bird's egg hatching into a Shiro Yummy before maturing, keeping the host in secured places in process. The Greeed, Giru and Dr. Kiyoto Maki on the other hand create Yummy from inanimate objects. Characteristics of a Yummy can be combined with another through two known methods, the first was developed by Kazari after absorbing Gamel and Mezool's Core Medals and by using any of their procedures, the second is when two Greeed use their methods at the same on the same object or person.

Similar to the Greeed, Yummies are composed of only Cell Medals and thus "bleed" Cell Medals when wounded or explode into a shower of them when destroyed. According the Ankh, the more desire a Yummy consumes, the stronger it becomes. In addition, the more powerful the Yummy, the more Cell Medals are produced upon its destruction while Shiro Yummy produce none at all. These Cell Medals are able to power up the Greeed, but the Kougami Foundation has created devices which run off their power. Yummies also wears a belt-like accessory on their waist with chains attached on it, plus a colored circle and metal buckles around the circle's sides. The chains on the Yummy's belt represents that Yummies are bound to human desires.

Should their host's primary desire suddenly change, the Yummy may split into two similar Yummy. The original Yummy will continue with the host's original desire while the new Yummy feeds off their new desire instead.

Their name is based off the English words Yummy, referring to how it eats objects of desire, mummy (マミー mamī'), referring to the Shiro Yummy form due their resemblance of an Egyptian Mummy, and to the Japanese word for darkness ( yami), due to them being mostly been created and driven by their human host's dark desires.

Later history

Shiro Yummy

Main article: Shiro Yummy

When one of the beings known as the Greeed approaches a human and asks what the human desires. A coin slot called a Medal Insert Slot (メダル投入スロット Medaru Tōnyū Surotto), which is also used on the Ridevendor, appears on the human, and after the Greeed inserts a mystical object called a Cell Medal (セルメダル Seru Medaru) into the slot, a mummy-like monster called a Shiro Yummy (白ヤミー Shiro Yamī) is formed from the human. Being the incarnation of its' host desire, a Shiro Yummy physically devours that person's object of desire and "digest them" into Cell Medals. Once consuming enough, a Shiro Yummy transforms into a complete Yummy, modeled after the animal on the Cell Medal.

"Roe" Yummy

An unspecified type of Yummy is the initial roe-like substance Mezool's Yummy take when she inserts her Cell Medals into the Medal Insert Slot. Like the Shiro Yummies they feed off the object of the host's desires "digesting" them into Cell Medals until they assume their complete form.

Kuzu Yummy

Main article: Kuzu Yummies

Kuzu Yummies (屑ヤミー Kuzu Yamī), or "Pseudo Yummies", are Shiro Yummy-like creatures that are not fully developed, each made from half a Cell Medal. They are weaker than Shiro Yummy although harder to destroy with physical attacks, but can be created easily by Uva for grunt work and do not require hosts.

Uva used these at a rapid rate for his final denouement.
