Michael's Campaign was an attempted genocide of both the Wraith and Pegasus humans by Michael Kenmore, who believed that neither species was fit to survive to rule the galaxy. He created a legion of hybrid soldiers to carry out his plan, kidnapping thousands of innocents and performing horrific experiments on them. Justifying his actions as no different from what the Atlantis Expedition did to him, he spared no one, determined to exterminate all of his enemies in one fell swoop through the use of the Hoffan drug. In the end, however, he was defeated when Teyla Emmagan bested him in hand-to-hand combat atop one of the spires of Atlantis, ending his reign of terror.
