Spoiler warning: This article discusses reportedly leaked footage from Avengers: Endgame Encore.

Avengers: Endgame Encore hits U.S. theaters Friday, September 25, but its new post-credit scenes have already leaked online - and they reportedly lay out major groundwork for December's Avengers: Doomsday.

The footage reportedly surfaced after early 4DX screenings in Busan, South Korea, and has circulated on Reddit and X despite Marvel Studios issuing repeated copyright strikes. Multiple outlets, including 9to5Marvel, say they've since viewed the clips directly.

According to the leaks, the re-release adds three new scenes. The first extends the film's original ending between Steve Rogers and Peggy Carter: after their reunion, a knock at the door reveals Loki standing outside. The second follows Bruce Banner, now grey-haired and isolated in an underground military bunker following the events of Spider-Man: Brand New Day. Banner insists no one can get in or out - until Doctor Doom's voice interrupts, reportedly telling him, "Mr. Banner, I'm here to collect you."

The third scene shifts to the Time Variance Authority, where Mobius and O.B. monitor a growing crisis: incursions between Earth-10005 (the Fox X-Men universe) and Earth-1127, an unseen reality, with O.B. reportedly warning that "the multiverse is collapsing."

None of the footage has been officially confirmed by Marvel Studios, and early viewer accounts differ slightly on details. Still, the scenes line up with what directors Anthony and Joe Russo have teased about Doomsday reshaping everything fans thought they knew from the original 2019 film - making Endgame Encore essential pre-viewing before Doomsday arrives December 18.
