Michael Kenmore is the name of the Hybrid who was transformed from a Wraith into a Human by the crew of the Atlantis expedition. The name was given to him by John Sheppard, but everyone, including other Wraith and Hybrids, call him by this name. Although he was transformed into a Human on two occasions, Michael was never able to fully revert back to his initial Wraith form. His DNA (and his appearance) would fluctuate back and forth over the years between that of a Wraith and that of a Human. His initial reversion into a Wraith was nearly complete. His skin pigment was grayish pale, his voice booming, and the feeding orifices in his palms returned. However, in the time since his second transformation into a Human, Michael experimented on himself and others, and his form settled closer to that of a Human.

He retained the strength, agility and regenerative abilities of the Wraith, while eliminating the need to feed on Humans, and with it his need for the feeding organ. There is also only one of the secondary Wraith "nostrils" located on the left side of the bridge of his nose, where Wraith have one on each side, but this is a physical trait shared with his fellow Hybrids. He became a major threat to the Pegasus Galaxy, but much of his army was destroyed by the Daedalus, crippling his power and he was later killed by Teyla after he attempted to destroy Atlantis.
