The Vorniax are the most popular and iconic of the Sheriff's recurring villains. They were introduced early in the first season in 1959.
The Vorniax hail from the constellation Fornax (The Furnace). They were originally created on the planet Kraos by the scientist Phaestos, who had a vision of the universe ending in ice. His creations are charged with the mission of forestalling the inevitable heat death of the universe. Their efforts in the universe are typically focused on advancing their empire (The Vornaxis) as well as heating the universe and engaging in activities which they believe will put off entropy. They first appeared in human history in the pre-Revolutionary War period in the colonial United States of America when Vorniax scouts inspired Benjamin Franklin to invent the "Franklin stove" (episode: "Revolution of the Vorniax". The Sheriff battled them many times during the run of the classic series. The first appearance in the new series was a lone surviving Vorniak found in an abandoned mine in Colorado (episode "Lonesome Vorniax")
Vorniax are superheatedorganic plasma energy beings, which need a vessel in which to go forth. Typically, this is in the form of a robotic exoskeleton with a furnace at the heart containing the burning "soul" of the Vorniax. These robotic forms are often disguised as kitchen stoves or furnaces, especially when present on Earth. When armed with weapons, these tend to be a branding iron, and an electric shock-whip. Their most common proclamation is "Burn! Burn! You will Burn!".
