Odin is the All-Father and ruler of Asgard. He is the son of Bor, brother of Vili and Ve, husband of Frigga and the father of Thor adoptive father of Loki. Odin is the wisest and by far the most powerful of the Asgardians.
When Ragnarok has been started due to the trickery of Loki, Hulk ends up breaking Odin's law by saving Skaar. The Agents of S.M.A.S.H. must set aside their differences with Thor, Heimdall, and the Warriors Three when Malekith the Accursed and his Dark Elves threaten to destroy the Nine Realms.
Hulk follows The Leader back in time to the Viking Age where they are apprehended by a young Thor and Loki who accuse them of trying to steal the fragments of the Berserker Staff. When Odin goes into his Odinsleep, Hulk teams up with Thor and Loki to keep Leader from taking the Asgardian throne from Odin. In the present, the Agents of S.M.A.S.H. fight to stop All-Father Leader from taking over the planet with Thor and Loki in his services as well as an army of gamma-powered Frost Giants.
Odin is well built and larger than Thor himself. His right eye is covered by a green patch and he wears a full-body armor and a golden crown. He has white hair and beard. He has a booming voice.
