Loki Laufeyson was the biological son of Laufey, the ruler of the Frost Giants in Jotunheim. Shortly after his birth, Loki was then abandoned and left to die. Found by Odin, he was taken to Asgard and raised by him and Frigga as an Asgardian prince, along with Thor. When Thor was to be crowned King, Loki had sabotaged the coronation by letting the Frost Giants attack Asgard, thus leading Thor to seek vengeance on Jotunheim, which resulted in Thor's banishment to Earth and Loki finding out the truth about his heritage. Frigga gave Loki the throne when Odin had fallen into the Odinsleep, however, when the Warriors Three and Sif attempted to return Thor home, Loki was forced to try to stop them. Regardless, Thor returned from his exile on Earth and ended Loki's reign. With Odin disapproving of his actions, Loki allowed himself to fall through the deep abyss of space, entering a wormhole created by the sudden termination of the Bitfrost Bridge.
