Thor (Marvel Cinematic Universe)

Thor Odinson is a character portrayed by Chris Hemsworth in the Marvel Cinematic Universe (MCU) media franchise, based on the Marvel Comics character and Norse mythological deity of the same name. He is depicted as the God of Thunder and one of the most powerful Asgardians, an ancient alien civilization with long ties to Earth whose members are considered gods by humans. Thor wields a powerful hammer called Mjolnir and is initially portrayed as the arrogant heir to the throne of Asgard whose brash behavior causes turmoil among the Nine Realms under Asgard's protection. This brings him into conflict with his treacherous adoptive brother, Loki.

Thor commits himself to the protection of Earth, and becomes a founding member of the Avengers. He eventually becomes the King of Asgard after Odin's death, but the entire realm is destroyed during the battle with his sister Hela. Thor then comes into conflict with Thanos, who slaughters half of the Asgardians and uses the Infinity Stones to erase half of the life in the universe before Thor himself kills Thanos. Thor later joins his fellow Avengers in obtaining the Stones from the past using time travel and they successfully undo Thanos' actions. When an alternate version of Thanos enters their timeline, Thor and the Avengers manage to defeat him. Thor then passes the crown of New Asgard to Valkyrie and joins the Guardians of the Galaxy for a brief time. Thor comes into conflict with Gorr the God Butcher and the Olympian god Zeus, while reconnecting with his terminally ill ex-girlfriend, the now Mjolnir-wielding Jane Foster. After Foster succumbs to her cancer to assist in Gorr's defeat, Thor adopts the latter's daughter, Love.

Thor is a central figure of the MCU, having appeared in nine films as of 2024. Thor's characterization and early films received mixed reception, however his storyline following Thor: Ragnarok (2017) was received much more favorably, with that film often being credited as revitalizing the character and his arc.

Alternate versions of Thor appear in the animated series What If...? (2021), with Hemsworth reprising the role. One version in particular, which depicts an alternate Thor raised without Loki who is recruited into the Guardians of the Multiverse by the Watcher in the battle against an alternate version of Ultron.
