History[]
A resistance group acquired a device, attempting to transport it somewhere, but the hideout was attacked by Dark Arrow. It was stolen with the Nazis proclaiming that their rule would last forever. The gateway was powered up to let the Earth-X villains go to Earth-1, with the large Wellenreiter timeship going through the breach as well. It was destroyed on the orders of General Winn Schott, originally intended by the Red Tornado.
