In the AnimeIn the anime, Fire Lion appears in the episode Junk Jam. Fire Lion is Nightmare's personal trash-burning demon beast. Upon being denied by Customer Service to have their alien garbage men stop dumping garbage on Dream Land until he pays his bills, King Dedede and Escargoon hack into Nightmare Enterprises' computer and ended up summoning Fire Lion in a plot to burn the trash that has piled up and covered
Dream Land, but later fought against Kirby. When Fire Lion was downloaded, he went out of control and attacked King Dedede. He also spewed fireballs everywhere, especially at the trash. Before Fire Lion had the chance to destroy the rest of Cappy Town, Kirby was able to become Fire Kirby and battle him. When Fire Lion shot forth a large stream of fire, Kirby countered and overpowered it with his own fire. Kirby also had the chance to grab Fire Lion and fling him out to the sea. Fire Lion exploded when touching the water, destroying him.

One of those Sammer Guys is called Molten Panther, possibly a reference to the Fire Lion.
- In Kirby's Adventure, Fire Lion's artwork and in-game sprite depicts him as a seemingly normal lion with blue fur and saber teeth.
