Marvel Studios gave fans at San Diego Comic-Con 2026 an exclusive look at Avengers: Doomsday, and while the footage has not been released publicly, eyewitness accounts suggest it may have fundamentally reshaped expectations for the MCU’s next crossover event.
The Hall H-exclusive sneak peek, screened on Saturday, July 25, 2026, focuses heavily on Doctor Doom (Robert Downey Jr.), his tragic past, his deep personal connection to the Fantastic Four, and his emotional confrontation with Reed Richards (Pedro Pascal). Rather than functioning as a conventional trailer, the footage builds the emotional stakes behind Marvel’s biggest villain while teasing the scale of the multiversal conflict awaiting audiences when Avengers: Doomsday arrives in theatres on December 18, 2026.
This wasn’t the only major reveal to come out of the panel, with a much wider wave of announcements shaking up what’s ahead for the MCU. To know more, read our article Marvel Just Rewrote Its Future at SDCC 2026 — Every Major MCU Announcement That Changes What’s Coming Next
Doctor Doom’s Past Finally Comes Into Focus
The exclusive footage continues directly from Doctor Doom’s mid-credits appearance in The Fantastic Four: First Steps, where he ominously appeared over Reed Richards and Sue Storm’s son, Franklin.
One of the biggest revelations is that Victor von Doom originates from the Fantastic Four’s Earth-828 rather than the primary MCU timeline, confirming that his history is deeply intertwined with Reed Richards and Sue Storm long before the events of Avengers: Doomsday.
Marvel has already given fans an official first look at the character in this exact pose, released ahead of the con. For more on that, read our post Avengers: Doomsday Official Concept Art Reveals Doctor Doom’s Epic First Look as Marvel Unites Avengers, Fantastic Four and X-Men
The footage reportedly opens with Doctor Doom sitting in full armour on a magnificent golden throne, positioned before a painting previously seen in promotional artwork as green energy pulses through the ground around him.
The emotional foundation of the preview comes from Sue Storm (Vanessa Kirby), whose narration introduces a far more tragic version of Victor than fans have previously seen.
She tells a gathering of heroes:
“Victor was always the smartest guy in the room. He used to be different. He used to be kind, used to be caring. But then everything he loved was taken from him. I knew he was lost, but I did not realize that he was broken.”
The dialogue establishes that Reed Richards, Sue Storm and Victor von Doom share a complicated personal history, making this conflict far more than another superhero-versus-villain battle.
Fan theories about the scale of that destruction have been circulating for a while, with some pointing to a specific comic arc as the likely inspiration.

Timeline: What Happens in the Hall H ‘Avengers: Doomsday’ Footage?

| Date | Saturday, July 25, 2026 |
| Footage Type | Exclusive Hall H sneak peek (not a public trailer) |
| Film | Avengers: Doomsday |
| Director | Anthony and Joe Russo |
| Release Date | December 18, 2026 |
The footage gradually escalates from emotional storytelling into large-scale destruction.
It transitions from Doom’s throne room to aerial shots of a completely devastated city, widely described as New York reduced to rubble, with some attendees noting similarities to destruction previously associated with Thor in earlier promotional material.
Standing amid the devastation, Pedro Pascal’s Reed Richards confronts Victor von Doom.
Reynolds’ surprise appearance quickly became one of the most talked-about moments of the entire panel in its own right. To see what happened, read our article Deadpool Crashed Marvel’s Avengers: Doomsday Panel at SDCC 2026—Was Ryan Reynolds Secretly Pitching Himself Into the Movie?
Reports describe Reed grabbing Doom and demanding answers with variations including:
“Victor. Did you do this?”
or
“Answer me Victor, did you do this?!”
The confrontation produces one of the preview’s defining lines.
Doctor Doom responds:
“All of you have lived stolen lives. Now you must give them back.”
Some eyewitnesses reported the second half slightly differently as:
“You refuse to give them back.”
As Doom speaks, the footage reportedly cuts between intimate family moments involving several Marvel heroes.
The montage includes:
- Steve Rogers/Captain America (Chris Evans) with a baby
- Thor (Chris Hemsworth) alongside his daughter introduced in Thor: Love and Thunder
- Ant-Man (Paul Rudd) with Cassie
- A crying Magneto
- Charles Xavier
The sequence strongly implies that Doctor Doom views the heroes’ happiness and family lives as “stolen,” reflecting the devastating losses that transformed him into Marvel’s greatest threat.
The action then intensifies dramatically.
Thor charges directly at Doom, threatening him with words reported along the lines of:
“I swear, you will beg for hell long before I grant it.”
Other attendees recalled a similar variation.
Before Thor can strike, Doctor Doom effortlessly stops the attack, with reports describing him either catching Stormbreaker or halting the assault with a single finger before launching Thor away using green magical energy.
Doom then delivers another unforgettable line:
“Hell answers to me.”
The preview concludes with Doctor Doom raising an army of Sentinels—the iconic mutant-hunting robots from Marvel’s X-Men mythology—from beneath the ground, teasing an unprecedented battle involving the Avengers, Fantastic Four, X-Men and numerous other heroes.

The Hall H presentation featured Kevin Feige, directors Anthony and Joe Russo, and an extensive cast that included Robert Downey Jr., Pedro Pascal, Vanessa Kirby, Chris Evans, Paul Rudd, Anthony Mackie, Letitia Wright, Simu Liu, and James Marsden alongside other returning X-Men actors.
One of the event’s biggest surprises came when Ryan Reynolds appeared dressed as Deadpool in a grey, denim-inspired costume variant, joking that he wanted to join the film.
The Russo brothers responded by saying that while principal photography had wrapped, they remained open to additional photography, leaving Reynolds’ involvement deliberately ambiguous.
During the panel, Pedro Pascal was asked about Reed Richards’ relationship with Doctor Doom. In response, he jokingly described them as:
“besties”
The remark drew laughter from the audience while playfully acknowledging one of Marvel Comics’ most iconic rivalries.
Robert Downey Jr. also joked about joining “the family of doom” and “the green side.”

What’s Next for Avengers: Doomsday?
Avengers: Doomsday is shaping up to be Marvel Studios’ largest crossover event to date, bringing together the Avengers, Fantastic Four, Thunderbolts, X-Men*, and numerous legacy Marvel characters.
Earlier marketing had already teased Chris Evans’ return as Captain America with a child, Thor alongside his daughter, the Fantastic Four meeting Wakanda, and the long-awaited integration of Fox-era X-Men characters into the MCU.
The Hall H footage expands those expectations by placing Doctor Doom’s tragic past and his rivalry with Reed Richards at the emotional centre of the story, elevating the conflict beyond spectacle alone.
Meanwhile, early ticket presales reportedly opened strongly, particularly for premium formats under Disney and Marvel’s Infinity Vision initiative, despite IMAX screens on the same release date being committed to Dune: Part Three.
With D23 expected to feature additional marketing and footage, Marvel fans are likely to receive an even deeper look at the film before its theatrical release on December 18, 2026.
Beyond this film, speculation is already building around where the MCU goes once this crossover concludes. To know more, read our article Marvel Phase 7 Rumors: Spider-Man 5, Black Panther 3, Shang-Chi 2 and New Avengers Reportedly Lead MCU’s Post-Secret Wars Future
