When Thor: Love and Thunder hits theaters, Jane Foster played by Natalie Portman will certainly transform into Lady Thor. How and when is still unclear, but a popular new fan theory suggests this event may somehow connect with the bizarre idea that Steve Rogers may be on the moon.
At the end of Avengers: Endgame, let's see Rogers impugnare Mjolnir as it crosses time. The hammer during the voyages could therefore have remained on the satellite, and this would give credence to the conspiracy theory that Joaquin Torres ha menzionato in The Falcon and the Winter Soldier.
As we know from the comics, during a battle with Nick Fury, Thor loses his ability to wield Mjolnir. The hammer thus remains unattended on the moon, from where he telepathically tries to get in touch with Jane who decides to give in to the call of the mythological object and is led to where she is. Once there, Jane wields Mjolnir, effectively gaining Thor's powers and transforming and improving his physique. Having long seen the god of thunder use it, Jane Foster quickly learns how to use the item, thus becoming Lady Thor.
We'll see how things turn out, meanwhile director Taika Waititi seems convinced that Thor: Love and Thunder will be the most brilliant Marvel movie ever.
