Bison Yummy

The Bison Yummy is a bison-themed Yummy that was created by Gamel from a Cell Medal born from Gamel's own desire to be amused of human suffering after witnessing a fight between married couple Takeshi Komori and Momoko Komori.

He has immense brute strength, pounding the ground with his fist to create a shock wave that lifts objects into the air to throw them at people. Later, after being overwhelmed by Kamen Rider OOO Latoraba, the Bison Yummy acts on his own to punish Kamen Rider OOO for temporarily blinding his master, attacking to attract the Kamen Rider's attention. However, the Bison Yummy is blinded by Kamen Rider OOO Lakiriba before being destroyed, with only a single Cell Medal remaining of him.

Later, a Bison Yummy also appeared in the Hyper Battle DVD, which was eventually destroyed by OOO in either Takagaruba's Champion Puncher or Kamen Rider OOO Takatoragaru, depending on the viewer's choices via "what-should-you-do-next" menu.

A Bison Yummy appeared in a zoo cage with a Shachi-Panda Yummy in File Gorilla: Hina and the Virtual Zoo, an installment in the Net Movie series Kamen Rider OOO Allstars: The 21 Leading Actors and Core Medals, both Yummies having previously appeared in the Hyper Battle DVD.

A Bison Yummy also appeared again in a city with a some Waste Yummy in 2068: Oma Time. He and the Waste Yummy are trying to attack Junichiro Tokiwa but the Bison Yummy and Waste Yummy are quickly destroyed by Kamen Rider Zi-O.
