Loki was born as a Jotunn, also known as a Frost Giant, in Jotunheim, but since his size was anything but of a giant, he was abandoned by his father, Laufey. He was found by Odin, king of Asgard, and adopted by him and his wife Frigga. Loki was transformed into an Asgardian, who resemble humans and raised along with their birth son, Thor. Loki was always jealous of Thor, the heir to the throne, but Frigga taught him how to use magic, which made him become a cunning trickster.
