Marvel endgame encore credits leak online ahead of release: sets up Avengers Doomsday

The re-release of Avengers: Endgame — dubbed Avengers: Endgame Encore — has added new post‑credits material that, according to multiple reports and circulating clips, directly tees up the next Marvel tentpole. The additional scenes, first sighted at early screenings and now appearing online, appear designed to bridge Endgame and the upcoming Avengers: Doomsday.

The Encore edition, which opened in select markets ahead of a wider rollout this week, was promoted as a connective piece ahead of Marvel’s next major release on December 18, 2026. Marvel reportedly inserted several minutes of previously unseen footage into the film — material viewers and studios hope will let returning and lapsed fans jump straight into the new chapter without watching every interim title.

Potential spoilers follow. The sequences described below come from social posts, forum threads and a handful of accounts on X/Twitter; early video clips of the end‑credit stingers have also circulated online. None of these items has been officially confirmed by Marvel, and reports differ on the order and exact content of the stingers.

What viewers are reporting

• Scene with Loki, Steve Rogers and Peggy Carter — Several accounts describe a short, quiet moment in an alternate timeline where Steve and Peggy are at home. A knock at the door prompts Peggy to ask whether she can help; the visitor replies that he cannot be helped but can offer help instead, revealing himself as Loki. The exchange is framed as ominous and intimate rather than action‑heavy.
• Hulk and Doctor Doom — Multiple sources describe a confrontation in which Bruce Banner is confined and attempting a new method to control his gamma side. The sequence reportedly cuts to a voice‑only appearance by Doctor Doom, who says something to the effect of “I’ve come to collect you” before a burst of green light and imagery of Latverian symbols — suggesting Doom either targets Banner or absorbs gamma power.
• Mask and metallurgy sequence — Another short stinger reportedly intercuts shots of Doom assembling his mask with the sounds of Tony Stark hammering metal while building his first Iron Man suit in 2008. The montage appears intended to link Doom’s rise to past Stark‑era origins.
• TVA alert: the multiverse is collapsing — A final scene set at the Time Variance Authority shows agents watching multiple realities collide. Characters including Mobius, O.B. and Ms. Minutes are named in postings, and monitors reportedly identify specific Earth designations (fans point to familiar and legacy universes). The sequence is described as a technical, procedural alarm rather than a full‑scale battle.

The accounts disagree about the order those stingers play and about some details. A Reddit post credited with compiling eyewitness reports lists four separate clips; an X/Twitter user who has posted earlier leaks claims the Hulk‑Doom beat is the first stinger and that Doom remains off‑screen, heard but not seen. Other viewers say the TVA material opened their screenings. Differences like these are common with early leaks from multiple territories.

Why this matters for Doomsday (and beyond)

If the reports are accurate, the new material appears intended to do two things at once: provide a quick narrative bridge for casual moviegoers, and drop seeds for the next phase of Marvel’s slate. A Doom‑Hulk pairing suggests Victor von Doom will pursue gamma‑level power, while a TVA warning about universes colliding signals a larger multiversal crisis that could feed into Avengers: Doomsday and subsequent events such as Avengers: Secret Wars.

The montage linking Doom’s mask to Tony Stark’s early workshop further implies the filmmakers are drawing thematic lines between legacy heroes and new antagonists — a storytelling move that would affect how familiar characters reappear in Phase 6.

For viewers who want the shortcut, Marvel has also publicized a recommended Disney+ watchlist of key projects that lead into the new Avengers arc; the Encore release is being pitched as an additional, theatrical catch‑up option.

How reliable are these reports?

Early eyewitness descriptions come from a mix of Reddit threads and posts on X/Twitter, with some users gathering multiple reports into a single summary. Within 48 hours of the first screenings, short clips of all four stingers reportedly began circulating online. That rapid spread makes independent verification easier but also increases the chance of altered or misattributed clips.

Until Marvel offers official scene summaries or releases the material themselves, the safest reading is that the Encore stingers are designed as connective tissue — plot hints rather than full reveals. Expect more concrete confirmation as higher‑quality footage becomes available and as the film reaches more markets.

Will you watch Endgame Encore to see how Marvel lays the groundwork for Doomsday, or wait for the official trailer and more context? Observations and first impressions are already proliferating online; they’ll likely shape fan expectations for the rest of the year.
