Marvel surprised the crowd at its D23 panel Friday night with new footage from Avengers: Doomsday, offering fans an exclusive look at the upcoming film.

In the clip, Sue Storm of the Fantastic Four tells the assembled Avengers that Victor Von Doom (Robert Downey Jr.) wasn't always the villain they're facing now, hinting that the character's turn followed the loss of everything he held dear, presumably including his wife and child. The footage cuts between close-ups of the ensemble cast as the moment lands.

The footage arrived just as Marvel unveiled the cast of its X-Men reboot, and the ensemble glimpsed in the Doomsday clip includes several of the franchise's Fox-era mutants, including Cyclops, Professor X, and Magneto.

The footage also delivers a jolt of action, showing RDJ's Doom shrug off a direct hit from Thor before summoning what appears to be a full army of Sentinels — the towering, mutant-hunting robots known for their flight capabilities and energy-blast attacks. Bad news for the good guys.

Avengers: Doomsday is set to hit theaters Dec. 18, 2026.
