Marvel Comics history
During the Age of Ultron storyline, Angela is revealed to have been pulled from Heaven as a result of damage to the multivariate. In a combination of rage and confusion, she charges toward the Earth from outer space, only to be intercepted by the Guardians of the Galaxy.
During the Original Sin storyline, it is revealed that she is the daughter of Odin and Frigga, making her the sister to Thor and Loki. She was "killed" as an infant during Asgard's war with the Angels of the Tenth Realm, called "Heven." This crime resulted in Odin severing the Tenth Realm from the other nine as punishment for their attack. Thor learns of his sister's existence when he was exposed to the secrets of Uatu, the Watcher's eye, by the Orb. He returns to Asgard to confront his mother about his sister's existence, and subsequently travels to the Tenth Realm with Loki to learn more about his sister. The Guardians of the Galaxy and Angela are attacked in warp space by a band of pirates, called Warpjackers. During the battle, Angela abandons the Guardians when the adult Loki telepathically tells her that the portal to Heven is open and that she can go home. As Thor battles Heven's guards, Angela appears having been guided to the doorway to Heven by Loki, and prepares to battle Thor. Angela defeats Thor, and is then told by the Queen of Angels to bring Thor to her. The now-female Loki tells Thor that being on the winning side seems just perfect. While Loki led an Angel fleet to Asgard, under the false pretense to help them destroy it, Thor escaped captivity and engaged once again Angela in combat. The fight between Thor and Angela is interrupted when Odin (who Loki freed from his self-exile) arrives where he recognized Angela as his daughter and revealed Angela's true lineage. Time ago, the Angel tasked to dispose Aldrif's body found out the baby was alive and raised her as one of the Angels under the name of Angela. Due to her services for the Angels, the Queen pardoned Angela her life, but exiled her from Heven due to her lineage. After leaving Heven, Odin tells Thor, Loki, and Angela that he still loves his children. Angela then decides to leave in order to explore the other realms.
