- "I am Freyr. Protector of the K'Tau world."
- ―Freyr
Freyr is a member of the advanced Asgard race and has a position on the Asgard High Council. SG-1 first encountered Freyr when Colonel Jack O'Neill met with the Asgard High Council on K'Tau regarding the damage of the K'Tau sun. (SG1: "Red Sky")
Freyr is mentioned again when SG-1 meets with the Asgard High Council about an asteroid threatening earth. Freyr and the rest of the Asgard High Council cannot intervene because the Protected Planets Treaty does not allow them to be protected against natural disasters. A frustrated Colonel O'Neill then made some inappropriate references to Freyr's mother. (SG1: "Fail Safe")
Freyr also asked SG-1 to rescue Heimdall and his research materials. Later, he commands an Asgard Fleet which confronts Anubis's motherships, saving SG-1, Heimdall, and Supreme Commander Thor. (SG1: "Revelations")
