Loki Odinson Laufeyson

A universe villain. Loki is one of several powerful beings from the magical realm of Asgard, who have been worshipped as gods. Odin, once the ruler of the Asgardian gods, led his subjects in a war against their enemy, the frost giants from the land of Jotunheim (one of the nine worlds of Asgard). Laufey, king of the frost giants, was slain in battle and the giants were defeated. Surveying the spoils of war, the Asgardians discovered a small Asgardian god-sized baby hidden at the giants' main fortress. The infant was Loki, whom Laufey had kept hidden due to his shame over his son's diminutive size. Odin remembered his father Bor’s dying words to adopt the son of a father killed by his hands; Odin adopted Loki into his own family, raising Loki like a son along with his biological son, Thor().
