Thor Odison is the Asgardian God of Thunder, former king of Asgard and New Asgard. Due to his irresponsible and reckless behaviour, he was banished to Earth and had his power taken. During the time on Earth, Thorn learned humility and fell in with the Jane Foster.
He was able to defeat the Distroyer and because of his act of sacrifice, he was granted his power, that he used against Loki’s scheme of genocide. He then became founding member of the Avengers, association that fights all the dangers and enemy against the Universe.
