What we know so far about Avengers: Doomsday has already reshaped fan expectations and dramatically expanded our understanding of Marvel’s next big event film. With all four teasers officially released by Marvel Studios, and several details leaked before their official drop, the picture around Doomsday is slowly becoming clearer—yet more mysterious at the same time.
Marvel has officially confirmed several appearances, while new leaks and rumors continue to surface, suggesting this could be one of the biggest MCU movies ever made. Some speculation even claims the runtime could approach four hours—though a three-hour epic feels far more realistic for theaters.
In this article, we break down everything we know so far about Avengers: Doomsday, including confirmed characters, teaser breakdowns, Russo Brothers’ hints, and the most talked-about leaks.
Confirmed and Expected Characters in Avengers: Doomsday
Based on official announcements, teaser footage, and credible leaks, here are the Marvel characters expected to appear in Avengers: Doomsday:
- Doctor Doom (played by Robert Downey Jr.)
- Loki, God of the Multiverse
- Thor
- Steve Rogers
- Peggy Carter
- Tobey Maguire as Spider-Man
- Doctor Octopus
- Shuri and the Wakandians
- M’Baku
- Fantastic Four members
- X-Men, including Cyclops
- Doctor Strange
- Iron Man (variant rumors)
- Ben Grimm
Notably, Bruce Banner / Hulk is rumored to be absent, which has raised many questions among fans.
Leaks suggest the movie will feature two major factions:
One led by Doctor Doom, and the other by the Avengers, both fighting to save—or control—the multiverse as incursions loom closer than ever.
Breaking Down the Four Official Doomsday Teasers
Teaser 1: Steve Rogers and the Timeline Paradox
The first teaser shocked fans by showing Steve Rogers alive in a timeline where he should not exist. We see him with Peggy Carter, holding a child—something that directly contradicts established MCU continuity.
This strongly hints at alternate timelines created by time travel, suggesting Steve lived out his life in a separate reality after Avengers: Endgame.
Teaser 2: Thor’s Emotional Plea
The second teaser focuses on Thor praying to Odin, not for victory—but to protect his daughter. He appears weakened and emotional, which is unusual for the God of Thunder.
Fans believe this hints that multiversal instability is draining even celestial-level beings, making Thor’s role deeply personal and emotionally driven.
Teaser 3: Wakanda, Namor, and the Desert Mystery
The third teaser brings us to Wakanda, where Shuri has taken up the Black Panther mantle and M’Baku appears as king. We also see Namor wearing a new suit, walking through a desert—far from water.
This suggests Wakanda may have relocated or sheltered Namor, possibly to limit his power or protect him from an unknown threat tied to incursions.
Teaser 4: X-Men Unleashed
The fourth teaser reveals the X-Men, with Cyclops in full rage mode, destroying everything around him using his optic blasts—something never before seen in the MCU.
Comic readers recognize this version of Cyclops immediately, making this one of the most hyped teaser moments so far.
Russo Brothers Confirm the Teasers Are Hidden Clues
According to the Russo Brothers, these teasers are not random scenes. They are deliberate clues tied directly to the story of Avengers: Doomsday.
Fans decoding timestamps and glitches discovered connections to Avengers: Endgame, specifically scenes involving time travel and the Infinity Stones. The common theme points toward one conclusion:
The Avengers interfering with the past triggered the rise of Doctor Doom and the multiversal incursions.
Doctor Doom’s Origin and Motivation (Rumored)
One of the strongest rumors claims that Doctor Doom’s family died due to timeline disruptions caused by the Avengers. Doom allegedly blames them for the collapse of his reality and seeks to take control of the multiverse to prevent further chaos.
This positions Doom not just as a villain—but as a tragic consequence of the Avengers’ past actions.
Shocking Leak: X-Men vs Tobey Maguire’s Spider-Man Universe
Another major leak claims the X-Men attack Tobey Maguire’s Spider-Man universe. To defend his world, Spider-Man teams up with Doctor Octopus, but they are ultimately overpowered.
Reports suggest Doctor Octopus sacrifices himself, while Loki intervenes to save Spider-Man. Importantly, insiders confirm Spider-Man does not die in Doomsday, though the fate of Doc Ock remains unclear.
Incursions, the Void, and the Final Battlefield
Leaks indicate one universe—possibly Tobey Maguire’s—is completely destroyed by an incursion. Doctor Doom reportedly escapes to the Void, a place previously seen in Loki and Deadpool & Wolverine, where erased realities end up.
Meanwhile, the Avengers may retreat to the Quantum Realm, setting up two opposing bases for the final multiversal war:
- Doctor Doom ruling the Void
- The Avengers regrouping in the Quantum Realm
Final Thoughts
While many details remain unconfirmed, one thing is clear:
Avengers: Doomsday is shaping up to be Marvel’s darkest, biggest, and most complex film yet.
With Doctor Doom, incursions, multiple universes collapsing, and heroes split across realities, the MCU is heading toward a confrontation that could redefine everything we know about Marvel storytelling.
And this is only the beginning.
