Gen-U-Tech Island

Gen-U-Tech Island was an artificial island used as a base by Dr. Phobos. It is where he developed the Medusa Device and the hybrid Venus. The isle was protected by a holographic shield that made it appear as if it were empty of habitation, but this didn't prevent the Manhattan Clan's invasion of it. They battled Xanatos and Demona in turn- both armed, one at a time, with Phobos's Medusa Device weapon- but had to abandon the island when Phobos set it to self-destruct. The island collapsed, and was destroyed. ("Venus In Stone", "Venus Rising")
