'Thor: Ragnarok': Who is Thor's Sister In The Comics?

Thor: Ragnarok introduces Thor's until-now unmentioned sister into the Marvel Cinematic Universe. While its true that Thor does have a sister in the Marvel Comics universe, it is not the same sister who appears in Thor: Ragnarok.

Thor: Ragnarok SPOILERS follow.

In Thor: Ragnarok, Odin reveals to Thor and Loki that his firstborn child was a daughter named Hel, the deadly goddess of death. Odin has been using his power to seal Hela away from the Nine Realms because her power had grown too great and too dangerous,

There is a similar but not quite the same origin for Thor's sister in the Marvel Comics universe, Aldrif Odinsdottir, aka Angela. Like the MCU's Hela, Angela was Odin's firstborn and the heir to the throne of Asgard. However, when Asgard went to war with the realm of Heven, the queen of the Angels who inhabit the tenth realm kidnapped Aldrif in an attempt to make Odin surrender. When Odin refused, the queen apparently killed the child and Odin, in his fury, cut Heven off from the World Tree, isolating it for generations.

The queen of Heven ordered her handmaiden to dispose of Aldrif's corpse, but the handmaiden discovered that the child was still alive. The handmaiden raised the girl as an angel under the name Angela and though Angela excelled at combat and exemplified the values of the Angels, she was constantly mocked and looked down on for not possessing wings.

The events of Age of Ultron cause a ripple in spacetime that pulled Angela away from Heven. She encountered the Guardians of the Galaxy on her way to Earth and joined them for a time.

Thor and Loki later returned Heven to the World Tree, which led to a confrontation with Angela, who proved more than up to the task of battling her brother Thor in combat. Angela eventually came to terms with her brothers, but her relationship with Asgard has been tense. She was raised to hate and mistrust Asgardians, but she was cast out of Heven for being one of them.

Since then, Angela has acted as an assassin for Asgard and even taken over control of Hel from Hela. She remains one of the most dangerous characters in the Ten Realms.
