Thorr Odinson is a villain from the Avengers and is an evil alternate reality version of Thor Odinson as well as a member of the Tyrant Avengers.
The reality of these Avengers was destroyed during an Incursion, but they were saved from their death by the A.I.M. of the main marvel universe and brought to said reality.
They escaped from A.I.M. Island and arrived to New York, wondering where were they, and realized they were in an alternate reality from that they came from. When Thorr realized the humans near him weren't on their knees, he killed them to teach a lesson. Shortly after, the Avengers were attacked by A.I.M.'s Adaptoids in order to bring them back to A.I.M. Island. However one of the Adaptoids had a rogue behavior which caused the death of Ant-Man, forcing A.I.M. to leave the battle and teleport away. The Avengers also teleported away.
Four hours later, the body of Ant-Man was found by S.H.I.E.L.D. The Avengers from this universe were called to investigate and found these Avengers in Times Square. Both teams of Avengers engaged in combat, and the tyrant Avengers begun to lose. During the fight, Thorr lost his hammer. After Wasp attempted to surrender along with an injured Iron Monger, Hulk arrived and reignited the fight. But A.I.M. stealthily captured both teams in a temporal shielding which made them stand still, and removed the tyrant Avengers in order to bring them back to their reality.
Back at A.I.M. Island, the Scientist Supreme offered the Avengers the opportunity to be taken to a new world, as General America wanted a world with no Avengers, they were taken to another reality
