Michael Kenmore, often known simply as Michael, was a Human-Wraith Hybrid who was transformed from a Wraith into a Human by the crew of the Atlantis expedition using the Iratus bug retrovirus. The name was given to him by Lt. Colonel John Sheppard, but everyone, including other Wraith and Hybrids, call him by this name. Since he was transformed into a Human on two occasions, Michael was never able to fully revert back to his initial Wraith form. Originally, his DNA (and his appearance) would fluctuate back and forth over the years between that of a Wraith and that of a Human.
