Fire Wyrms are uncommon enemies that appear in Kid Icarus Uprising. They are underworld monsters that resemble flaming skeletal dragons. They attack by ramming into foes, and get shorter as they take damage. They are led by Hades and the various gods and commanders who serve him.
Early on in Uprising, Most Wyrms were fiery spirits, but later on, most if not all were artificially created out of many human souls. Additionally, when the robotic aliens known as Aurum invade Earth, the fire wyrm is among the creatures they attempt to create mimics of.
