Genetically engineered race of beings created by Michael. A cross between the iratus bug, Wraith and human, Michael took more than a year developing various phases of the race before arriving at a formula which would satisfy his needs most.
The first generation of soldiers were along the order of giant, bipedal iratus bugs. Later incarnations included a race of sightless beings which hunted by sound and emitted a gas from their necks, thus disguising themselves.
Michael attempted at least two prior generations of creations before arriving at the right balance -- beings with certain "superior" qualities of Wraith, but without the need to feed on humans. The final generation required human hosts to which Michael's hybrid DNA would mold. The Athosians were among the first inhabitants of the Pegasus Galaxy Michael used for his experimentation, including Kanaan.
Michael's hybrids serve many functions, but their primary purpose is to protect their creator. Additionally, they serve as ground troops and are trained to operate both his equipment and Wraith technology.
It is likely Michael's hybrids are programmed with the same genetic code he has gifted his other creations: an inability to turn on Michael himself.
It was Michael's plan to use Torren Emmagan, the son of Kanaan and Teyla Emmagan, to further perfect his hybrids. As both parents possessed the gift of Wraith DNA, so did the offspring. Twice Michael attempted to acquire the infant, and twice he failed.
