DESCRIPTION AND HISTORY

A technologically advanced race residing outside the Milky Way galaxy. They have technology far superior to that of the Goa'uld.

The Asgard maintain a "Protected Planets' Treaty" with the Goa'uld. Protecting certain planets from Goa'uld domination, but also preventing the Asgard from interfering in natural events on these planets, which would render the treaty void.

Currently at war with the Replicators in their own galaxy, the Asgard have very few resources to enforce the Protected Planets' Treaty. A few incidents have occurred between the Goa'uld and the Asgard since Anubis' return among the System Lords, but a full-scale war between the two powers in unlikely.

Freyr
An Asgard commander, he met SG-1 when the sun of the K'tau system threatened to go nova and destroy the planet. He noted the non-interference of the Asgard as part of the Protected Planets' Treaty articles.

He saved SG-1 from the clutches of Anubis by confronting his mothership with three O'Neill-class cruisers which convinced the powerful Goa'uld to retreat.

Heimdall
A scientist, he is researching into the genetic history of the Asgard. He does this in order to find a cure for the genetic degradation due to the Asgard cloning process.

Thor
Supreme commander of the Asgard fleet. He protected the planet of Cimmeria with a device that destroyed Goa'uld symbiotes called "Thor's Hammer". He suggested to the System Lords that Earth be added to the Protected Planets' Treaty.

He was taken to Earth on his ship infested with Replicators, but was saved by SG-1 who crashed the ship in order to completely destroy the Replicators.

After being in a coma for some time due to Anubis' information extraction, he recovered thanks to information brought by SG-1 from Anubis' abandonned mothership that crashed in the Pacific Ocean. He encountered SG-1 in the stolen ship Prometheus for reasons that remain unknown for the moment.
