MCU Phase 4: Natalie Portman's Jane Foster may wield the old Mjolnir or forge a new one in 'Thor: Love and Thunder'
The Mjolnir from 'Avengers: Endgame' was from 2013, which after the battle looks to have been safely replaced by Cap after the battle with Thanos.
'Thor: Love and Thunder' will introduce us to formidable foes, new allies, a new Thor, and hopefully, a jacked Chris Hemsworth as the God of Thunder that we know and love. In Natalie Portman's Jane Foster, we're all set to see the first female Thor in the MCU and as far as we know Thors are particular about their weapons. Speaking of which, Hemsworth's Thor needn't be worried. He's got the Stormbreaker and he's still worthy of wielding Mjolnir, his trusty hammer. However, there are questions about how Foster got the hammer.
Last we saw, Steve Rogers aka Captain America (Chris Evans) wielded the hammer and handed Thanos (Josh Brolin) a walloping in 'Avengers: Endgame'. As much as an unforgettable scene that was, it also proved Rogers was worthy of lifting Mjolnir and the man did more than just lift. The hammer and the shield were used in tandem to peg Thanos on the backfoot. All the while, Thor was busy lighting up the rest of mad Titan's army.
You can relive the Cap lifting Mjolnir scene here:
The final few minutes of the movie sees Cap take Mjolnir with him when he goes back in time to return the Infinity Stones to their original timelines. This explains how Foster got her hands on Mjolnir unless Marvel decides to hand her a different weapon. If we were to break down Mjolnir's presence in 'Love and Thunder' in detail, we have to trace its timeline all the way back to 'Thor: Ragnarok'. The indestructible hammer, or at least that's what it looked like, was blown to smithereens by Hela, the Goddess of Death. The Mjolnir from 'Avengers: Endgame' was from 2013, which after the battle looks to have been safely replaced by Cap after the battle with Thanos.
Now, this is the working theory of how Foster gets to wield her hammer. Should the MCU decide to forge a new hammer just for the new Queen of Asgard, then that's a different story altogether. That essentially gives us the possibility of Mjolnir's rebirth— a more stronger, powerful version than its predecessor. The latest comics reveal the truth behind the hammer. Mjolnir contained Tempest, or better known as 'The Mother of Storms'— a cosmic force which Thor wielded through Mjolnir. After the old one gets destroyed, Thor proves himself worthy again and Tempest collects the fragments and slivers of the shattered weapon to forge a much powerful Mjolnir. This could probably happen in 'Thor: Love and Thunder'. If this is the case, it also means Thor, or at least the person chosen will be the most powerful God of Thunder in the MCU.
It still remains to be seen if we see Foster wielding the old Mjolnir or a newly forged one. 'Thor: Love and Thunder' hits cinemas on November 5, 2021.
