Fthaggua

Fthaggua the Flame-Feeder is a fire-based vampiric Mischiever and the son of Cthugha as well as a brother of Aphoom-Zhah. He is a nihilistic fire-based conqueror and destroyer who is made of mana fire and has extensions of his will known as Fire Vampires, who all act like arms and can annihilate and consume anyone rather instantaneously. He was first documented by Donald Wandrei as the central antagonist of The Fire Vampires, where in the distant future, his comet of Ktynga approached the Earth and sent a message demanding to either sacrifice some of their finest leaders or his Fire Vampires would annihilate a mass amount of the Earth's population, having done so already, and when one of the demanded leaders is absent, more are taken with another threat of taking more than what was previously taken. But the scientist Norby manages to create a device that uses the Fire Vampires' own energy against them when he realizes they are merely an extension of his will, destroying them once and for all. But this story, told by Donald Wandrei after sensing it as his precognitive scribe reincarnation Alan Marsdale, was actually a training mission where Fthaggua was sent into the future by Yog-Sothoth so that he may get the power and experience to defeat Randolph Carter by taking out humanity at a stronger point in their history since he failed to do so long ago when he arrived in the Dreamlands crashing in the Eastern Deserts and making a crater and a surrounding wasteland of geothermal formations. But when he failed his future mission, he responded to his father and brother's scorn by consuming dozens of worlds before taking his destruction towards Yuggoth. But he almost fell into a trap set by Donald as Alan and Randolph's new apprentice Luz, but the trap was exposed when Cthugha and Aphoom sacrificed themselves and took his place in the trap, getting sent to the Hibernation Realm while Fthaggua would retaliate by consuming many in Kadath and bribes Luz by sacrificing herself for everyone's lives, but only ends up disintegrating and consuming a clone of Luz planted by Alan that had a banishment glyph drawn on her back, causing him to literally suck himself into a banishment glyph to the Hibernation Realm and sustaining a stab in the mouth with Luz's Lovecraftium sword when he taunts her. In an additional indignity, his horrible attack would be circumvented by time travel, again by Luz, but with an alien from one of the alien worlds a bad tirade would've ruined, which in a past-tense would prevent his attack. His previous Outer God form is unknown, but some have guessed that he was once a Space Councilor with more emphasis on fire, or a particularly hot-tempered Power Cosmic Powerian.
