Fat Lion

The Fat Lion (ファットライオン Fatto Raion) is a creature developed by Dr. Indigo using the chemical SIQ for Shiki's plot to use monstrous animals to attack East Blue to force the World Government to submit to him. It is a bloated lion with its mane spiky and reaching to the end of its back. Its legs are small for its body.

The funky king of beasts, he deceives others with his plump and cute appearance, before instantly making them victims of his atrocious fangs.

The Fat Lion can first be scene in Volume 0 Strong World on the Island of Merveille. He's later seen in One Piece Film: Strong World chasing the Black Brothers and Luffy, but the Fat Lion and the scorpions are defeated by Billy.
