Gorgon
The first Gorgon was a supervillain on the world of Angor, an otherdimensional duplicate of Earth. The Extremists wiped out Angor in a nuclear explosion, leaving only themselves and a few heroes who fled to Earth. The Extremists pursued them and it was revealed all but one of them had died and the surviving one, Dreamslayer, used androids of his comrades, including Gorgon. They were deactivated and stored in the Watchtower.
