What Happened to Mjolnir in Thor Movies, And How Jane Foster Was Able To Wield It?
Jane Foster appears to have returned, rocking Thor's armor and, most importantly, his earlier-destroyed weapon, Mjolnir. How come?
The final accord of the 'Thor: Love and Thunder ' trailer was impressive, with Jane Foster, portrayed by Natalie Portman, wielding Thor's hammer Mjolnir in a very Captain America-style scene.
The hammer itself, however, looked somewhat jacked up, apparently re-assembled from little pieces. In 'Thor: Ragnarok', the God of Thunder's sister Hela effortlessly destroyed Thor's signature weapon, prompting him to craft another one, later dubbed Stormbreaker.
And here is Jane Foster now, with the long-missed Mjolnir in her hands. How could the hammer return from the… well, not dead, but shattered?
First of all, we are now well-aware of different timelines and different universes in the MCU. In 'Avengers: Endgame', when Mjolnir was wielded by both Thor and Captain America, it was taken from the past, with Thor emotionally moved upon realizing he was "still worthy".
It is unclear, however, whether there will be any time-travel in 'Thor: Love and Thunder'. Moreover, if Mjolnir was taken from the past again, it would unlikely be looking so knackered, so it seems that Jane Foster is wielding that very hammer that was destroyed by Hela.
That Mjolnir is supposed to still lay on a cliff in Norway, where Asgard's enfant terrible shattered it to pieces. Only the presence of someone worthy could restore it – either that of Thor, or of Jane Foster, with her re-assembling Mjolnir possibly finalizing her transformation into Mighty Thor.
Given that Thor vocally expressed his desire to find peace and end his superhero days, this could mean a possible new beginning in the MCU for Jane Foster, who may assume his position. However, it remains unclear whether Natalie Portman will appear in 'Thor: Love and Thunder' for a one-time big adventure, or if Marvel has any long-standing plans for her.
