the Dominators were inspired to invade Earth when a time travelling Booster Gold inadvertently led them to believe that fifty-two planets were planning an attack on the Dominion. They managed to seize control of Earth's technology, and sent genetically modified warriors (created using gene grafts from the former members of Terror Firma) through a stargate. The Legion, with the help of the Wanderers, managed to defeat this armada. The Dominators still had thousands of super-powered troops at their disposal, and would eventually regroup. Under the orders of Cosmic Boy, Mon-El detonated a bomb that seemingly destroyed them. In fact, it imprisoned their entire planet in the Phantom Zone.
