452 Avengers Endgame : Thor

As they were en route to Earth, their ship was attacked by Thanos and the Black Order, who took the the Tesseract and murdered his brother, before leaving Thor for dead. He was rescued by the Guardians of the Galaxy and had teamed up with Rocket Raccoon and Groot to travel to Nidavellir. With the help of Eitri, Thor crafted Stormbreaker and aided the nation of Wakanda and the Avengers in confronting Thanos and his forces. However, Thor squandered his chance to kill Thanos with his new weapon and Thanos activated the completed Infinity Gauntlet and erased half the universe's population from existence. After the Avengers were joined by Captain Marvel, the team traveled to the Garden, where Thor and the Avengers ambushed Thanos, discovering that the Titan destroyed the Stones, ensuring that a reversal of his actions was now impossible. Enraged, Thor beheaded Thanos using Stormbreaker and left the planet.
