LEGO Marvel Fall 2026 Rumours: Doctor Doom Bust and Avengers Tower Could Be Coming

Rumours are beginning to swirl around the LEGO Marvel lineup for Fall 2026, and if the leaks prove accurate, Marvel fans could be heading into one of the most exciting seasons for superhero sets in years. According to reports circulating in the LEGO community and highlighted by the Brick Reporter YouTube channel, two major Marvel-themed releases are currently being discussed: a Doctor Doom bust arriving in September and a playable Avengers Tower set launching shortly afterwards.

While nothing is officially confirmed yet, the details being shared are already generating huge excitement among collectors and builders alike.

Doctor Doom Bust Rumoured to Join LEGO’s Growing Marvel Display Range

The first rumoured LEGO® Marvel set that has fans buzzing is the Doctor Doom Bust, said to contain 379 pieces and release in September 2026. If accurate, the set would join LEGO’s growing range of Marvel display busts such as Iron Spider-Man and Iron Man models that focus on character-focused shelf displays. The piece count is notably similar to previous bust sets, which suggests LEGO could be continuing a consistent display format across the theme.

Doctor Doom Returns to LEGO After More Than a Decade

Even more exciting is the rumour that the set could include a Doctor Doom minifigure, potentially the first new version of the iconic Marvel villain in over a decade.

Doctor Doom is one of Marvel’s most recognisable villains, and his distinctive armour, hood and mask would translate incredibly well into LEGO form. A detailed bust with metallic elements and dark green highlights could easily become one of the standout display pieces of the year. If LEGO introduces a new hood mould or updated printing for the minifigure, collectors could see this set quickly become a must-have. For fans of Marvel villains, it might even rival some of the most striking LEGO character displays released in recent years.

New Avengers Tower Playset Could Bring Marvel Action Back to LEGO Cities

Hot on its heels is another rumoured set that leans more toward play and storytelling: a new Avengers Tower playset, reportedly containing 954 pieces and priced around $110. Compared to the massive collector-scale Avengers Tower sets released previously, this rumoured version appears to be much more accessible and play-focused.

In fact, the piece count places it firmly in the category of LEGO’s mid-sized modular-style playsets, similar in spirit to the Daily Bugle battle sets or other Marvel location builds.

Marvel Fans Speculate on Minifigure Line-Up and Play Potential

What could make this set especially exciting is the potential minifigure lineup. LEGO has often used Avengers Tower sets as an opportunity to include a wide range of heroes and villains, and with the Marvel universe constantly expanding, speculation is already running wild.

Fans are hoping to see characters like Iron Man, Captain America, Thor, and maybe even some unexpected inclusions such as Doctor Doom himself if LEGO is tying the wave into upcoming Marvel storylines.

Could LEGO Be Building Toward an Avengers vs Doctor Doom Storyline?

Some rumours suggest that these sets could align with the wider Marvel narrative leading into the upcoming Avengers: Doomsday storyline, which would make the timing particularly interesting. A Doctor Doom display set arriving first, followed by a playable Avengers Tower, would create a thematic build-up to the larger conflict.

For collectors and Marvel fans, it would feel like LEGO is telling a story across the lineup rather than simply releasing isolated sets.

Speculation Builds Around a Possible LEGO Helicarrier Release

And the excitement might not stop there. Many LEGO insiders believe that this fall Marvel wave could culminate in a much larger collector release. There is growing speculation around a new Helicarrier set, potentially arriving later in the year during the Black Friday shopping period.

Historically, LEGO has used the late November window to launch large flagship sets aimed at adult builders, and a new Helicarrier would certainly fit that strategy. Previous versions of the Helicarrier have ranged from play-scale models to massive collector builds with thousands of pieces.

If this rumour proves true, LEGO Marvel fans could be looking at a stacked release window: a striking villain display bust, a fun and accessible Avengers Tower playset, and possibly a massive Helicarrier finale to close out the year.

Final Thoughts: Fall 2026 Could Be Huge for LEGO Marvel Fans

Of course, until LEGO officially confirms these sets, all of this remains speculation. But if the leaks are even close to accurate, Fall 2026 could be one of the most exciting seasons for LEGO Marvel in years.

For collectors, investors and Marvel fans alike, it might be time to start clearing some shelf space — because the Avengers appear to be assembling once again in brick form.
