Hela is a fictional character, the Asgardian goddess of death in the Marvel Comics universe, based loosely on the Norse myths of the goddess Hel. The ruler of Hel and Niffleheim, the character has been a frequent foe of Thor. Hela first appeared in Journey into Mystery #102 and was adapted from Norse Myths by Stan Lee and Jack Kirby.
Hela was born in Jotunheim, the land of the giants. According to legend she was the child of the trickster Loki and the giantess Angrboda. When she came of age, Odin appointed her as the Goddess of Death, giving her rulership over the dead in the realms of Hel and Niffleheim.
Hela often tried to expand her power to the dead who dwell in Valhalla as well. These attempts often brought Hela into conflict with Odin or his son Thor. She once appeared to Thor while he was on the verge of death after battling the Wrecker who knocked a building onto him while he was depowered. However, she failed to tempt Thor into entering Valhalla, despite an image of one that dwelled in Valhalla.
Later, she stole a portion of the sleeping Odin's soul while he was on the Sea of Eternal Night due to Loki, thus creating the powerful entity Infinity. Hela then unleashed Infinity upon the universe. Infinity even took control of Odin. Hela slew Thor, who was restored to life by the sacrifice of her servant, the Silent One. Hela was then slain by Odin to save Thor, but then returned to life by Odin after being convinced by Thor to restore the natural balance of life and death. Hela slew Thor, but restored him to life after Sif offered to die in his place.
