Marvel Fans Upset Over New ‘Avengers 5’ Leaks: Trailer Delay & Loki’s Rumored Role Spark Backlash

Marvel’s upcoming blockbuster Avengers: Doomsday is once again the center of online speculation — and this time, the latest leaks have left fans frustrated rather than excited. Over the past 24 hours, two major rumors have gone viral: one about the release date of the movie’s first trailer, and another regarding Loki’s role in the MCU’s next big ensemble film.

Trailer Rumor: No Online Release Before December 17?

A fresh leak from industry insider DanielRPK, known for accurate trailer predictions, suggests that Avengers: Doomsday’s first teaser will not drop online before December 17, 2025. Instead, the teaser is reportedly set to debut exclusively in theaters ahead of Avatar 3: Fire and Ash, which begins rollout the same day.

Earlier reports indicated Marvel would release the trailer before the end of the year, sparking huge anticipation. Fans expected a drop in early December, then December 11 — but both dates passed without any footage.

Now, if DanielRPK’s info is correct, Disney may be holding the teaser to boost Avatar 3’s opening-week attendance. Some fans are already predicting the trailer will leak from theaters anyway, as often happens with such exclusives.

Loki Leak: A Stand-In for the Beyonders?

The second rumor comes from The Cosmic Circus’ Alex Perez, who claims that Loki will stand in for the Beyonders — the godlike cosmic beings central to the 2015 Secret Wars storyline.

In the comics, Doctor Doom absorbs the Beyonders’ power to create “Battleworld,” a stitched-together planet made from multiversal fragments. The rumor suggests that instead of introducing the Beyonders, Marvel might simplify the plot by positioning Loki as the key multiversal power source Doom needs.

This aligns with the ending of Loki Season 2, where the God of Mischief becomes the multiverse’s protector, holding all timelines together.

Fans React: Confused, Annoyed, and Unimpressed

Across Reddit and X/Twitter, reactions haven’t been kind:

Some fans say the rumored trailer strategy is “pointless” and guarantees leak videos within hours.

Others are unhappy that Marvel might rewrite major comic lore to center Loki in a storyline where he never originally appeared.

Many simply feel fatigued by constant changes, delays, and rumors in the MCU’s multiverse saga.

Don’t Forget: These Are Still Just Rumors

Marvel has not confirmed any details about the trailer timeline or Loki’s role. As with all leaks, it’s best to wait for official announcements — especially with Avengers: Doomsday still a year away from release.

Release Date

Avengers: Doomsday hits theatres December 18, 2026.
