Thor Odinson (Earth-1546)

Thor is the son of Odin and the Asgardian God of Thunder. He was sent to earth to learn some humility, which he did. He helped found the Avengers until Doom started taking over. With the Avengers gone, Thor went up against Doom alone but lost. He decided it wasn't the best time to fight so he went to Asgard and now he is with new allies.

Fall of the Avengers
Thor was a member of the Avengers when Doom rallied criminals for a ten day battle against the heroes. During this, Thor saved Hawkeye by shoving Taskmaster through a wall. Thor helped Hawkeye to flee from the battle before returning to attempt to fight Doctor Doom alone. He was badly beaten, but escaped to his home.

Fall of the Nine Realms
Thor returned to Asgard, only to find the world mostly destroyed by both Surtur and Hela. Gathering the remaining forces, including Odin and Heimdall, they fled to find a new home. At some point, the Elves and Dwarves joined this search after the Curtain of Hope and founded New Asgard.
