Hela (/ˈhɛlə/) is a fictional character appearing in American comic books published by Marvel Comics. The Asgardian goddess of death is based on the Norse goddess, Hel. The ruler of Hel and Niflheim, the character has been a frequent foe of Thor. Debuting in the Silver Age of comic books, Hela first appeared in Journey into Mystery #102 and was adapted from Norse mythology by editor/writer Stan Lee and artist/writer Jack Kirby.
Hela was born in Jotunheim, the land of the giants. She is the child of Loki (albeit a different incarnation who died during a previous Asgardian Ragnarok) and the giantess Angrboða. When she came of age, Odin appointed her as the Goddess of the Dead, giving her rulership over the dead in the realms of Hel and Niflheim.
