Litleo are quadruped, feline Pokémon. They are mostly dark brown in color with pale brown paws, ears, tail tip, and face. They have a short, rounded muzzle with a reddish orange nose and round ears. Their eyes are circular with black irises and white pupils and sclera. There is a reddish orange tuft of fur between their ears. Each of their paws has three toes and a dark brown paw pad. Their tail ends in a pointed, teardrop shape.
In battle, its tuft of fur radiates heat, and when up against a strong opponent, the temperature increases. When wild Litleo grow stronger, they leave the pack and begin to live alone. Litleo is a hot-blooded Pokémon that is quick to start fights. It and its evolution Pyroar are the only known Pokémon capable of learning Noble Roar.
In PAORAS02 a Litleo appears on the ticket to the Space Center, given from Ruby to Sapphire to watch the Litleonid meteor shower after their current mission.
