An Asgardian is an immortal inhabitants of their glorious realm Asgard ruled by Odin, The Allfather. They have different roles as gods, warriors and peasants. They loved the Allfather except for Loki, a half-Asgardian and a half-Frost Giant and a god of mischief. They faithfully protected Odin during his Odinsleep with their lives from the forces of evil every year.
When Loki took over Asgard, some Asgardians swore allegiance to him and defended him. But they were defeated by the Avengers, the Warriors Three and the Valkyries. After the defeat of Loki, they renew their allegiance to Odin again and praised the Avengers as true heroes despite their mortal lives.
