The Lion Yummy (ライオンヤミー Raion Yamī) is created by Kazari throughout the desire of the king to become stronger along with Cockroach Yummy and Whale Yummy in the Kamen Rider OOO novel. Just after their creation, all of them are in their stronger forms due to the king's unlimited desire though they have been defeated by the king and a betraying Ankh.
- The Lion Yummy is the only Yummy created by Kazari whose motif corresponds with one of his Core Medals, which are used by Kamen Rider OOO to assume Latorartar Combo. Neither the Tora Yummy or Cheetah Yummy have been shown to exist in any medium.
