Cold Flames



It looks like fire, it crackles like fire, and it even burns like fire. However, it isn't really fire.

It looks like fire because that's what the Master of Illusion wants you to see. Despite crackling, it consumes no air, burns no fuel and creates no smoke. If it generates heat or burns victims, it's because Your Mind Makes It Real. Even if it can incinerate a chair, it rarely spreads to the rest of the room. It probably deals less damage than straight-up pyrokinesis, too, though it can likely bypass resistances to fire. And a quick Tap On the Head to the creator likely puts them all out.

Also known as Marsh Lights, Fox Fire, Ghost Lights, Will O the Wisp and Ignis Fatuus, these are illusionary flames created by the supernatural, or are themselves a supernatural being like Ghosts or fairies. Living characters like illusionists, spiritualists and even supernatural martial artists can create Cold Flames through Soul Power, Ki or illusions, or by using Elemental Powers like Ice to create literal Cold Flames.

Visually, it's going to be a Technicolor Fire that isn't red-orange-yellow, usually blue or white to help denote the unnatural nature of the flames. It usually also has other, spooooky supernatural properties. Since it doesn't need a conventional fuel source, it can float around of its own accord, acting as a guide (or to get people lost) or as a Guardian Entity. Magicians may change the "fuel source" to something like poisons and use it to "burn them away", healing patients. In combat, the caster can make the Cold Flames Friendly Fireproof and not worry about harming allies. This property has the added bonus of letting casters wreath themselves in flame to look cool.

Hellfire is an inversion; fire which is even more dangerous.

Anime and Manga

 * Saint Seiya the Lost Canvas has Ignis Fatuus as an attack for the Cancer Saint, who, appropriately enough, uses Soul Power to create "soul flames" (or something).
 * The flames around in Yomotsu Hirasaka are basically will o' wisps that use souls as fuel to sustain themselves. This attack is just the weaponized form of this.
 * In D Gray Man one akuma had the ability to shoot ice fire, which it used to trap Allen when he and Lenalee were fighting against him and 2 other akuma in an alleyway. Oddly, he said it burned hotter then normal fire despite the fact that it could clearly be seen freezing around Allen's leg like ice.
 * Certain species of Digimon utilize this for different reasons. Some, like Gabumon and its evolutions, use it as a theme for their attacks. Others, like Kyuubimon and its counterpart Youkomon have it covering their bodies, be it as part of their attacks or simply as part of their design.
 * Tomoe from Kamisama Kiss uses them, not surprising considering he is a Kitsune. In fact, he has developed a rather interesting, and rather sadistic, use for them by combining them with Baleful Polymorph. First he will transform his opponent into a game animal of some kind (a trout, an ostrich, etc...) and then use his fox-fire to cook them alive.
 * One variety of mushi featured in Mushishi feeds off human body heat by appearing to its victims as an open flame. If a person huddles close to it for warmth, it saps their heat from them until they freeze to death.
