The Fate of Mjolnir in Avengers: Endgame and Beyond

In Avengers: Endgame, Captain America (Steve Rogers) wields Mjolnir, Thor’s enchanted hammer, during the climactic battle against Thanos. After the battle, Steve returns to the past to return the Infinity Stones to their original timelines. During this process, Mjolnir is also given back to Thor.

When Steve Rogers returns to the present as an old man, having lived a full life with Peggy Carter, it is implied that Mjolnir remains with Thor. The film does not explicitly show the fate of Mjolnir but emphasizes the passing of the torch, with Steve proving himself worthy to wield the hammer and solidifying his legacy as a hero.

Timeline of Mjolnir’s Journey

Mjolnir was returned to the point in the timeline when Thor (played by Christian Bale) stole it from his younger self. If Steve did his job correctly, which we can trust he did, younger Thor never noticed it was missing and continued to use it throughout the remaining events of Thor: The Dark World, the events of Avengers: Age of Ultron, and onwards until its destruction in Thor: Ragnarok.

Steve returned Mjolnir along with the Reality Stone/Aether to 2013 Asgard, where it belonged. He knew that if Mjolnir were to go missing during the Dark World episodes, Thor would be in peril. Therefore, Steve took the hammer to ensure it was correctly placed in its original timeline.

Mjolnir was also involved in the interdimensional journey with the Infinity Stones. Steve brought Mjolnir from 2013 to 2023 so that he could return it to its correct time along with the other stones. This action was crucial to prevent potential chaos and ensure that essential artifacts were in their rightful place.

Thor’s Adventures and Mjolnir’s Fate

2023 brought Thor into the dark world time period, where he and Rockett went to get the Aether/reality stone. Steve left Mjolnir with Thor, so what happened after Thor entered the Dark World? That’s right, we have Thor: Ragnarok. What happened to Mjolnir in that movie… yeah, those events still played out.

In Thor: Ragnarok, Mjolnir was used extensively, both by Thor and the antagonists Hela and Loki. It was during these events that the hammer faced significant challenges and was briefly destroyed. However, it was not destroyed but rather shattered as part of Hela’s plan, which proved crucial to the story's narrative.

Despite the destruction, Mjolnir ultimately returned to Thor, reflecting the enduring nature of the legendary weapon and its connection to its rightful owner. Thor, as the new god of thunder, continued to wield Mjolnir, drawing strength from it and in turn using its power to protect Midgard.

The fate of Mjolnir is a testament to its significance in the Marvel Cinematic Universe, a symbol of leadership, power, and the unbreakable bond between Thor and his mighty hammer. Its journey through time and its role in major events underscore its importance in the overarching narrative of the Avengers' story.
