Elder Demon
The Elder Demon is a Marvel comics supervillain and an enemy of Silver Surfer.


The Elder Demon was trapped in a crystal by an unnamed alien race and used to power their city, which was located at the heart of a comet.

Thanos and Galactus both desired the power source of the comet, never guessing that it was actually the Elder Demon. Thanos dispatched White Raven to claim it, and Galactus sent Silver Surfer for the same purpose. White Raven ended up breaking the crystal, releasing the Demon. The Demon destroyed a caretaking automaton, the last remnant of the race that had imprisoned him. He announced that he would make every living being in the universe pay for his imprisonment. The Demon easily bested the Surfer, but was destroyed when Raven impaled him with her spaceship and set it to self-destruct.
