Fire Vipers are an evil species of snake-like monster that are the ideal minions of dark Portal Masters in the Skylanders series. They made their first appearance in the game, Skylanders: SWAP Force. They are enormous snakes that have the ability to fly and breathe fire. Their notable weakness are the large main Evilizer Crystals that grow from their heads and within their bodies.
Kaos' Mom used a swarm of Fire Vipers to attack the Ancient Elementals atop the Cloudbreak Volcano, but they were defeated the SWAP Force Skylanders.
