“From Steve to Bucky”- All Avenger Teams appearing in Doomsday – The Fandom Journal
All Avenger Teams Appearing in Avengers: Doomsday (2026)
As the Marvel Cinematic Universe charges toward Avengers: Doomsday (2026), fans are preparing for one of the most explosive events in superhero history. With multiple generations of heroes, two leadership factions, and the return of Robert Downey Jr. as a Doom variant, the stakes couldn’t be higher. This event is set to unite (and possibly sacrifice) several teams in the multiversal fight to stop the collapse of all realities.
Here’s a full breakdown of every Avengers team expected to appear in Doomsday, their leaders, legacies, and what they’ll bring to the MCU’s next major phase.

1. From Steve Rogers to Bucky Barnes
The legacy of the Avengers began with Steve Rogers, who led the team with unwavering integrity from Captain America: The First Avenger (2011) through Avengers: Endgame (2019). Whether battling alien invasions or resisting government overreach in Civil War, Steve was the moral center of the Avengers. His friendship with Bucky Barnes shaped much of the emotional core of the franchise — culminating in Steve’s retirement and Bucky’s attempt to find peace.
Now, Bucky is no longer hiding. In Thunderbolts, he takes command of a team of reformed anti-heroes, stepping up as a battle-hardened leader trying to atone for his dark past as the Winter Soldier. His rise from assassin to Avenger is one of the MCU’s most powerful redemption arcs — and it’s far from over.
2. Young Avengers: A Team That Might Not Rise
Marvel’s post-Endgame direction included setting up the Young Avengers, with characters like America Chavez, Kate Bishop, Kamala Khan (Ms. Marvel), and others scattered across Disney+ shows and Phase 4 movies. These younger heroes were meant to represent a new era.
However, with recent Marvel projects underperforming both critically and commercially, it appears that the Young Avengers project has quietly been put on hold. While America Chavez and Ms. Marvel (ifkyk) may still appear in Doomsday, don’t expect a full-fledged Young Avengers team to form. Marvel seems to be refocusing on legacy heroes and multiversal threats.
3. The Thunderbolts accidently The New Avengers
With Thunderbolts delivering a surprising hit — $173.0 million in five days — Marvel is now positioning them as the official New Avengers. Led by Bucky Barnes, and featuring Yelena Belova, U.S. Agent, Red Guardian, Ghost, and Taskmaster, this team represents a grittier, morally grey side of superheroism.
— The real excitement? The rumored showdown between Sentry and Doctor Doom. With Sentry’s god-like power and unstable mind, fans are eager to see what happens when he goes up against RDJ’s confirmed Doom variant. It’s a battle that could shake the multiverse — or tear it apart (If marvel goes hard, not really expecting though).
However, many believe the Thunderbolts might be used as sacrificial pawns, much like the X-Men variants in Doctor Strange in the Multiverse of Madness. Their tragic fate could be the emotional fuel that propels the remaining Avengers forward into Secret Wars.

4. Sam Wilson’s Avengers: The Official Legacy Team
While Bucky leads the Thunderbolts, Sam Wilson, the new Captain America, is quietly assembling his own Avengers squad — a traditional team rooted in legacy and heroism. The Thunderbolts post-credit scene teases that Sam is in favor of forming a new team, likely consisting of:
Spider-Man
Doctor Strange
Hulk
Captain Marvel
Shang-Chi
Wanda ( Expected )
Thor ( Expected )
M’Baku
Ant Man
Gambit ( Expected )
Sue Strom ( Expected )
Thing ( Expected )
This is the team that will face off against the multiversal threat alongside Bucky’s squad. The MCU is clearly setting up two Avengers factions, each tackling different angles of the war against Doctor Doom or probably Civil War 2.
The Russo Brothers were also confirmed to direct post credit of Thunderbolts as the directors for Avengers: Doomsday, bringing the signature scope and emotional weight they delivered in Infinity War and Endgame but this time with F4.
This year’s San Diego Comic-Con (July 24–27, 2025) is now expected to announce the next phase of films and team lineups, building toward Secret Wars in 2027.
5. Fantastic Four & X-Men: Incursions and Multiversal Collisions
The Fantastic Four are finally entering the MCU this year in The Fantastic Four: First Steps (July 25, 2025), with Reed Richards playing a crucial role in understanding and stopping the incursions — the collapse of one universe into another, a concept introduced in Doctor Strange 2. These multiversal collisions will be a key plot device in Doomsday and eventually Secret Wars.
Reed Richards and Spider-Man are expected to have the most screen time after RDJ, helping unite fractured multiverse factions to fight Doom. Meanwhile, X-Men variants are also expected to appear — likely in limited or sacrificial roles — showcasing the destruction caused by incursions and heightening the stakes of multiversal warfare.

7. Conclusion: The Avengers Legacy Lives On — In New Forms
From Steve Rogers’ shield to Bucky Barnes’ burden, and Sam Wilson’s rise as a leader, the Avengers are evolving. Avengers: Doomsday is more than a sequel — it’s a transformation. With new teams, multiversal threats, legacy characters returning, and the confirmed return of RDJ as a villain, the MCU is gearing up for its most ambitious and emotionally charged chapter yet after post endgame failures Kevin is taking charge again First with Daredevil and Now Doomsday.
Whether you’re rooting for Bucky’s Thunderbolts, Sam’s new Avengers, or Reed’s multiversal rescue squad, one thing is certain:
