Avengers: Doomsday‘s first trailer brings back several Marvel Cinematic Universe characters, including Tom Hiddleston’s Loki, and it seems like the footage might confirm the biggest theory for the God of Stories’ role in the upcoming movie. Loki has gone on quite the journey in the MCU movie timeline. The character started as a villain, serving as The Avengers‘ main foe.
Years later, Loki would enter heroic territory, teaming up with his brother in Thor: Ragnarok, which signaled a major change for Hiddleston’s character. That continued with Loki being killed by Thanos at the start of Avengers: Infinity War for trying to take out the Mad Titan and protect his brother. Then, Avengers: Endgame brought in a Loki from an alternate timeline.
That version of Loki escaped with the Tesseract after the events of The Avengers, being apprehended by the Time Variance Authority (TVA). In what many view as the MCU’s best TV show, Loki, Hiddleston’s character went on a self-discovery journey filled with time travel, magic, and major reveals. Loki became the all-powerful protector of the multiverse at the end of Loki season 2.
While that looked like a fitting final chapter for the character in the franchise, Loki was confirmed as part of Avengers: Doomsday‘s cast. Now, after a long wait, Marvel has released the first Avengers: Doomsday trailer. The footage features a major surprise regarding Loki’s role, and it seems like this confirms the biggest Loki theory for the MCU movie.
Avengers: Doomsday’s Trailer Brings Back Loki & Seemingly Confirms A Major Theory
Surprisingly, Loki does not appear with the same outfit he was last seen in the MCU. At the end of Loki season 2, the character underwent a transformation to become the MCU’s God of Stories, conjuring green robes to sit at his throne and watch over the multiverse. However, Loki shows up in his signature TVA uniform in the first Avengers: Doomsday trailer, which is vastly different. This starts to pose questions, as the version of Loki that appears in the Avengers movie might be one from before Loki season 2’s ending. Sure, the back of his TVA badge has the Yggdrasil symbol.
This would hint at Loki coming from after the season 2 finale and the multiversal tree’s creation. That said, Marvel has been cleverly editing trailers to serve as misdirection for quite some time, so there is no way of knowing whether Loki is truly holding his badge as implied by the trailer. Judging by the bright curtains and the general interior of where Loki appears in the Avengers: Doomsday trailer, the former God of Mischief appears to be at the same home Steve Rogers and Peggy Carter were seen in Avengers: Endgame and that Chris Evans returned to in the first Avengers: Doomsday teaser.
Due to that, Loki’s biggest Avengers: Doomsday theory might pan out. That would be related to how many believe that Loki, having stopped branching timelines while working for the TVA, would be called upon to fix an anomaly caused by Steve’s decision to stay in the past with Peggy, which created a branched timeline. There are many alternatives to what could come out of such a meeting, but the fact that Evans’ Steve returns in Avengers: Doomsday confirms that if Loki really met him, he decided not to prune Steve, but likely helped him.
How Loki’s Reunion With Thor Is Closer After The Avengers: Doomsday Trailer
Loki meeting Steve, as the Avengers: Doomsday theory suggests and the trailer teases, is interesting in itself. That said, it becomes even better due to the final stretch of the new footage. Evans’ Steve Rogers reunites with Chris Hemsworth’s Thor at the end of the new Avengers: Doomsday trailer. With the two together, a Thor and Loki reunion would be the closest it has ever been.
After all, if Loki were to help Steve in the past, then the latter would be able to tell Thor that a version of his brother was alive and working at the TVA. This would set up the reunion that everyone wants to see in Avengers: Doomsday, and the new trailer makes that even more likely.
