Details regarding three new LEGO Avengers: Doomsday sets that are planned for release in the near future have been leaked online. Avengers: Doomsday is set to be released in December 2026, and LEGO's plans for the upcoming blockbuster are starting to become a little clearer thanks to this latest leak.

Marvel has been a significant IP for LEGO over the years, with tons of superheroes to draw inspiration from for an enormous number of sets. There have been some awesome Marvel LEGO sets based on the MCU, paying homage to some of the franchise's most iconic moments in brick form. And with Avengers: Doomsday just five months away, it's going to be another huge period for LEGO Marvel.

Leaked LEGO Avengers: Doomsday Sets Reveal Movie Set Pieces

Coming via Unibricks on the LEGONewsAndRumors subreddit, the first details about upcoming Avengers: Doomsday LEGO sets have been revealed. The first set is the Avengers Quinjet, which has already had previous sets in the past. The upcoming version will feature 433 pieces in total and is priced at $59.99, with minifigures of Doctor Doom, Sam Wilson's Captain America, The Thing, and Cyclops. However, no release window has been given for this LEGO Marvel set. Next is the Sentinel Battle, which comes in at $99.99 and 846 pieces. The post gives this a release window of October 2026, two months before the movie drops, with minifigures of Doctor Doom, Thor, Mystique, Mr. Fantastic, Magneto, and Nightcrawler. It is also set to feature a brick-built Sentinel, a damaged Sentinel head, and a sign for the X-Mansion.

Finally, the biggest set revealed in this leak is the New Avengers Tower, which has 954 pieces in total as well as a $109.99 price tag. Minifigures for this one include Doctor Doom, a "flame on" version of the Human Torch, Sentry, Red Guardian, Bucky, and Yelena. Like the Avengers Quinjet, there is no release window given for the New Avengers Tower LEGO set, but it's likely to arrive before the film's December 2026 release window.

Test your knowledge.

These leaks align with earlier LEGO Marvel leaks from the start of 2026, which revealed the prices of the 76347, 76348, and 76352 sets but not their contents. That report also outlined plans for additional sets for the rest of the year, suggesting there could be more to come from LEGO Avengers: Doomsday. However, it's worth remembering that LEGO has not yet officially revealed these sets, so these leaks should be treated as rumors until the company confirms otherwise.
