Asgard commander of the Asgard
mothership Valhalla. Aegir reported the readiness of the strike force in orbit of the new home world, Orilla
, and the loss of contact with the colony on the planet. Later he informed Supreme Commander Thor
regarding the presence of a humanoid Replicator floating in space.
It is believed (but not confirmed) that Aegir perished when the Asgard race collectively ended their civilization, unable to solve the genetic degradation problem in their reproductive cloning program.
