Tom Hiddleston’s Loki last appeared in this summer’s box-office crushing Avengers: Endgame. Our heroes time-traveled back to 2012’s Chitauri attack on New York City to get their hands on the Time, Mind, and Space stones. In a turn of events, Loki was able to make his escape with the Space stone; creating a whole new branch timeline in the process. This new “branch timeline” Loki will be the protagonist of the new Disney+show, Loki, that is scheduled to release in the Spring of 2021.
A new production logline provided to FandomWire states that “[Loki] Follows Loki after the events in Avengers: Endgame as the trickster uses the power of the Tesseract to travel throughout human history and change historical events,” seemingly confirming other rumors of the series premise.
FandomWire also reports that Loki will end with the God of Mischief using the Tesseract to hop through the multiverse… returning to the main MCU timeline/dimension, just in time for Thor: Love & Thunder. And much like how Mjolnir made a big comeback in Avengers: Endgame via time travel, the hammer will be returning to our main timeline along with Loki at the end of the Disney+ show.
And this will reportedly set things up for Jane Foster to become Thor and wield Mjölnir in Thor: Love & Thunder.
