Superdemon is the primary superhero in the magic reality Earth 13.
History
Etrigan, rocketed to an Earth of eternal twilight from the doomed planet Kamelot, fights evil in Merlin's name alongside the League of Shadows as the Superdemon.[1]
His world was invaded by a mysterious group of vampires from an alternate world who captured him and his league, but the mortal form of Etrigan managed to release him and easily destroyed the vampiric invaders and released his comrades. His fellow leaguers realized that they were facing a Vampre invasion, but now they were ready, waiting for them.
Thus when the vampires finally crossed to their home, the entire League of Shadows charged against the Super-Vampires, with Etrigan facing off the Vampire Ultraman.[2]
Etrigan was one of the supermen of the multiverse that were targeted by Prophecy, who wanted to capture them to steal their powers, but Etrigan was warned by Justice Incarnate, and after a fight, he went out to the spaceship with them, where they came up with a plan to free the other supermen.[3] Alongside other Supermen, he defeated Prophecy before returning to his own world.[4]
