Heimdall

An Asgard scientist eager to uncover the genetic mysteries of his species' ancestors, Heimdall is willing to risk his own fate to protect a vital experiment he is pursuing. He is fully aware that because the Asgard have become unable to sexually reproduce, the species is forced to clone themselves (copies of copies of copies), effectively making them a dying race. Heimdall led a research outpost set up in the Milky Way galaxy, far from the threat of the Replicators, and was determined to discover a link between his ancestors and the present-day Asgard. Their scientists came across a capsule that had drifted between the Milky Way and Ida galaxies, containing an ancient and primitive Asgard with the ability to reproduce through meiosis. Unfortunately, the outpost was located by Anubis' envoy, Osiris, and destroyed. But SG-1 helped Heimdall escape with his ancestor's remains aboard a Tel'tak.

It is Heimdall's hope that he will be able to locate ties within the two genetic pools of past and present Asgard to release the deadlock of forced reproduction through mitosis (cloning), perhaps saving the Asgard from this sole means of reproduction and, thus, saving the entire species from certain extinction.
