In a move that’s sending shockwaves through the superhero cosmos, Marvel Studios has announced the theatrical re-release of Avengers: Endgame on September 25, 2026, just months before the highly anticipated Avengers: Doomsday hits screens on December 18. This isn’t your standard nostalgia play; the re-release will feature a brand-new post-credit scene that directly teases Doomsday, serving as Marvel’s clever bridge between the Infinity Saga’s epic finale and the Multiverse Saga’s cataclysmic climax. Fans are already buzzing about how this unexpected addition will reshape perceptions of Tony Stark’s legacy, potentially linking his sacrificial snap to the rise of Robert Downey Jr.’s Victor von Doom. As the MCU grapples with post-Endgame fatigue, this strategic revival aims to reignite the spark, reminding audiences why Endgame remains a cultural juggernaut and setting the stage for what could be the franchise’s most ambitious crossover yet.

Avengers: Endgame, directed by Anthony and Joe Russo, exploded onto screens on April 26, 2019, as the culmination of 22 interconnected films and a decade of Marvel magic. Picking up five years after Thanos’ universe-halving Snap in Avengers: Infinity War, the film reunited the scattered Avengers—Tony Stark (Robert Downey Jr.), Steve Rogers (Chris Evans), Natasha Romanoff (Scarlett Johansson), Bruce Banner (Mark Ruffalo), Thor (Chris Hemsworth), Clint Barton (Jeremy Renner), and newcomers like Carol Danvers (Brie Larson) and Scott Lang (Paul Rudd)—in a desperate gambit to undo the devastation. The plot’s ingenious time heist saw the team splinter across timelines: a 2012 New York battle for the Space and Mind Stones, a 2013 Asgard heist for the Reality Stone, and a 2014 Morag/Vormir mission for the Power and Soul Stones, culminating in Natasha’s heartbreaking sacrifice on Vormir. Back in the present, Hulk’s reverse Snap restored the dusted, only for 2014 Thanos to invade, leading to the earth-shaking Battle of Earth. Tony’s ultimate sacrifice—wielding the Infinity Stones to dust Thanos and his army—sealed the Infinity Saga, but at the cost of his life, leaving fans in tears and theaters in awe.

The film’s legacy is monumental. Grossing $2.799 billion worldwide ($858 million domestic, $1.941 billion international), it shattered records: biggest global opening ($1.2 billion), fastest to $1 billion (five days), and highest-grossing film until Avatar‘s 2021 re-release dethroned it. It earned a 94% Rotten Tomatoes score, with praise for its emotional depth, fan-service callbacks, and visual spectacle. Nominated for Best Visual Effects at the Oscars, it won an Annie Award and multiple Critics’ Choice nods. Critically, it was hailed as a satisfying capstone, though some faulted its time-travel mechanics. Culturally, it birthed memes (“On your left,” “Avengers… assemble”), sparked thinkpieces on heroism and loss, and solidified the MCU as Hollywood’s dominant force. Re-released in June 2019 with bonus content (including a deleted Katherine Langford scene as an older Morgan Stark), it added $37 million domestic. Now, this 2026 return—timed between Spider-Man: Brand New Day (July 31) and Doomsday—aims to eclipse Avatar once more, potentially pushing past $3 billion with IMAX premiums and global fervor.

What makes this re-release revolutionary is the new post-credit scene, rumored to directly setup Avengers: Doomsday. Sources like MCU Source and Daniel RPK claim it ties Tony’s snap to Doom’s emergence, perhaps showing a multiversal ripple where Stark’s actions birth incursions—colliding realities that Doom exploits. Fan theories abound: one posits the hammering at Endgame‘s end (Tony forging his family life) mirrors Doom crafting his mask, symbolizing twisted parallels. Another speculates Steve Rogers’ past-life choice with Peggy Carter triggers Doom’s family tragedy in Latveria, fueling his conquest. The Russos, returning to direct Doomsday after helming Civil War, Infinity War, and Endgame, have teased “the greatest pre-game is the Endgame,” hinting at narrative continuity. This scene could retcon or expand Endgame‘s epilogue, showing Doom observing the Avengers’ victory from afar, setting his multiversal takeover.

Avengers: Doomsday, originally Avengers: The Kang Dynasty until Jonathan Majors’ exit, pivots to Doctor Doom (Downey Jr.) as the big bad. Downey’s shocking Comic-Con 2024 reveal—unmasking amid Doom doubles—ignited frenzy, blending his Iron Man charisma with Doom’s tyrannical genius. Plot rumors suggest Doom, from a ravaged Earth-828, conquers via incursions, absorbing powers and realities. The film unites the Avengers (Anthony Mackie as Captain America, Chris Hemsworth as Thor, Sebastian Stan as Winter Soldier, Paul Rudd as Ant-Man), Wakandans (Letitia Wright as Shuri, Winston Duke as M’Baku), Fantastic Four (Pedro Pascal as Reed Richards, Vanessa Kirby as Sue Storm, Joseph Quinn as Johnny Storm, Ebon Moss-Bachrach as Ben Grimm), New Avengers from Thunderbolts* (Florence Pugh as Yelena, Wyatt Russell as U.S. Agent), and X-Men (Patrick Stewart as Xavier, Ian McKellen as Magneto). Villains include Namor (Tenoch Huerta) and perhaps Kang variants. Directed by the Russos from a Michael Waldron/Stephen McFeely script, filming wrapped September 2025 in the UK and Bahrain, with a $300 million budget eyeing IMAX spectacles.

Marvel’s re-release strategy echoes Disney’s Avatar playbook—reissues boosted Cameron’s epic past Endgame in 2021. Endgame previously returned in 2019 with added footage, earning $37 million. This time, the Doomsday tease could lure casuals and superfans, potentially adding $100-200 million globally. Reddit threads speculate double features with Infinity War, while X buzzes with #EndgameReRelease theories: “Doom watching Tony’s snap, mirroring his own loss?” one user posted. Box-office analysts predict it challenges Avatar‘s throne again, especially if Doomsday‘s trailer attaches like Avatar: Fire and Ash‘s rumored teaser.

The MCU’s post-Endgame era—Phases 4-5—faced “superhero fatigue” critiques, with Eternals and Quantumania underperforming amid narrative sprawl. Doomsday aims to refocus: a direct Endgame sequel vibe, ignoring some Multiverse detours per rumors. Downey’s Doom isn’t a Stark variant but exploits the resemblance, manipulating Avengers’ grief. Plot whispers include Doom’s Latverian origin, incursion wars, and a Battleworld setup for Secret Wars (December 17, 2027). Cameos abound: Tom Hiddleston as Loki, Simu Liu as Shang-Chi, and perhaps Tom Holland’s Spider-Man sidelined per leaks.

This re-release isn’t mere fan service; it’s Marvel’s reset button. By linking Endgame to Doomsday, it honors the Infinity Saga while propelling the Multiverse forward. As fans dust off their arc reactors, theaters brace for another snap—proving the Avengers’ legacy endures, one re-release at a time.
