Lastlight

Michael Kenmore was the name the Atlantis expedition gave to a Wraith that they tested the Iratus bug retrovirus on. His conversion from Wraith to human was successful, but Michael retained some of his memories, and realized that the rest of the expedition mistrusted him, with only Teyla Emmagan attempting to sympathize with him. Eventually, Michael learned what had happened to him, and kidnapped Teyla while returning to his hive. Teyla was rescued, but the Wraith were also aware that Atlantis was intact.

Upon telling his queen of the retrovirus, their hive allied with the Expedition on the pretense of using it to feed on other Wraith. The alliance, however, was a trap to learn the location of Earth, and acquire a means of getting there.

Mistrusted by his hive and queen, who know saw him as an abberation, Michael chose to ally with Lieutenant Colonel John Sheppard in his attempts to stop the hive ships from reaching Earth. They were successful, with Michael suggesting that they use the gas on his hive.

Still mistrusted by the Expedition, Michael was forced back onto the retrovirus, and grouped with the other transformed Wraith. He and about thirty others suspected something was wrong, and killed the squad assigned to guard Doctor Carson Beckett. Having already begun to revert, the Wraith summoned another hive. Sheppard ordered Rodney McKay to orbitally bombard the surface of the planet they were on to prevent any Wraith from leaving. Michael was presumed kill.
