The Elementals of Doom are embodiment of the four elements: Air, Water, Fire and Earth. They are summoned through the power of the ancient Tailsmans of Power. The origins of the Tailsmans of Power and the Elementals are unknown. They were first seen in the modern age when the ancient alchemist stole the Tailsmans from various museums around the world and used the Elementals to try and destroy his long time foes the Fantastic Four. Each member was forced to fight an Elemental that countered their powers perfectly. It wasn't until the Fantastic Four's leader Mister Fantastic suggested they swap foes were the Elementals seemingly destroyed. With the aid of Doctor Strange, Diablo was apprehended and the Tailsmans confiscated.
