Marvel's Avengers: Doomsday leaked footage removed online

A blurry video purportedly from the upcoming Marvel Cinematic Universe film *Avengers: Doomsday* surfaced on social platforms, showing an X‑Men and Avengers team confronting Doctor Doom and metallic allies. The clip, which featured unfinished VFX of characters such as Nightcrawler, Beast, Cyclops, Steve Rogers, Gambit and Shang‑Chi, quickly spread across X/Twitter and Reddit, prompting speculation about its origin and authenticity.

The footage was subsequently taken down after a copyright notice indicated it had been disabled at the request of the rights holder. Analysts and fans debated whether the leak was genuine, AI‑generated, or a deliberate promotional move by Marvel. The movie is scheduled for worldwide release on December 18, 2026, and the incident has heightened anticipation for an official trailer.
