Leaked Avengers Endgame Footage Plays Directly Into Loki Disguise Conspiracy

Marvel Studios’ Avengers: Endgame is set for a surprise theatrical re-release on September 25, and new footage from that cut has already leaked online in poor-quality clips filmed at a live preview screening. The additions were originally announced by the Russo brothers earlier this year as a bridge to this December’s Avengers: Doomsday, but the footage that has surfaced so far appears to lean directly into a long-circulating fan theory that Captain America is actually Loki in disguise.

According to the leaked material, the scene begins where Steve Rogers returns to the past to reunite with Peggy Carter, but the cut now continues past their kiss. The pair are distracted by a sound, Cap hides, and Peggy opens the front door to find Loki walking in. The crowd at the screening can be heard cheering, before Rogers steps out and the two exchange forlorn glances before the film cuts to the credits. That is only a fraction of what is reportedly new, however, and the full extent of the additions remains unclear.

A Sneak Peek From the Big Screen

The footage reached the internet via a Reddit post, though it has already been taken down. What remains visible is limited, but the details reported elsewhere paint a much larger picture. GamesRadar noted that the film’s earlier release in Korea includes scenes involving Loki and his Time Variance Authority companions investigating an overlap between Earth-10005 — the classic X-Men universe set to resurface in Doomsday — and a new location, Earth-1127. Notably, there is no mention of the Fantastic Four’s Earth-828, which is surprising given that is where Doom appears to be based.

Miss Minutes reportedly appears to instruct audiences to stay put, before the footage apparently shows Loki, Morbius and Ouroboros becoming involved, with missiles fired and thousands of incursions occurring simultaneously as the multiverse begins to collapse. None of that is visible in the leaked clip, which suggests the new material is spread unevenly across different showings.

The Loki Disguise Theory Gains Traction

What makes this leak particularly intriguing is how it feeds a theory that has been circulating since the Doomsday trailer first appeared. We know Captain America is in Doomsday, as he features prominently in the trailer, and most fans assume it is the real Steve Rogers because he is seen wielding Mjölnir — a hammer previously established as only worthy to be held by Thor or Rogers.

But Loki’s appearance in the past directly plays into the idea that the man holding the hammer may not be Rogers at all. Historically, the trickster god was never deemed worthy of Mjölnir despite being Thor’s brother and a deity in his own right. That changed, however, following his redemption arc across the two seasons of the Loki Disney+ series, in which he ultimately sacrificed himself to hold the timelines together. His transformation has left many convinced that he is now more than worthy enough to wield the hammer — and this new footage seems to be leaning right into that possibility.

Looking Ahead

The mystery will likely be resolved soon, with Doomsday scheduled to open in theaters on December 18. Until then, fans may well revisit Endgame in cinemas for the sake of a couple of minutes of new footage, even as the uneven length of different screenings continues to fuel confusion about exactly what will be added. The full scope of the re-release remains to be seen, but for now the leaked clip has done one thing well: it has turned a two-minute scene into one of the MCU’s most talked-about conspiracies.

For those who want to re-watch before the truth is revealed, the safest bet is to hold off — the leak is only going to make the disguise theory harder to dismiss.

Editor’s note

Whether this is genuine new footage or a clever piece of fan editing remains to be confirmed, but the combination of a theatrical re-release, a multiverse collapse, and a Loki reveal has never been more compelling. As Doomsday approaches, the question is no longer whether Loki is in the film — it is whether he is really the man holding the hammer.
