The Fire Cats in the Aladdin TV series episode "In the Heat of the Fright", in which Mirage is introduced.
Aladdin, Abu, Genie and Iago are following a river, making a map of the country nearing it, when they discover a village attacked by many demonic cats of fire, which can turn into fireballs. They engage a fight against the evil felines and manage to defeat them thanks to Genie's abundant tears. (He was watching Bambi on a TV set above the village: the moment when Bambi's mother is killed.)
The fire cats then return to Morbia where their queen, Mirage, the Evil Incarnate furiously remarks that they have been defeated. Mirage takes this as a personal challenge and drags Aladdin and his friends to Morbia, where they are tracked down by the hungry fire cats. Genie resolves to defeat Mirage on his own, and he goes to her temple, but fear gets the better of him and he proves unable to do any harm to the fire cats. As mirage revels in Genie's cowardice, Aladdin confronts her, claiming that Genie is no coward, given that he was brave enough to challenge her, thus restoring Genie's confidence. Being no longer afraid of them, Genie cannot be harmed by the fire cats and he defeats them with ease. Mirage lets them go, swearing revenge and adding a name to Aladdin's long list of foes.
