A series of LEGO leaks may have revealed some interesting details for Avengers: Endgame. The merchandise delved into spoiler territory for what could happen in the film.

No matter how hard Marvel tries to prevent Avengers: Endgame spoilers from leaking, it is impossible to stop at least a few details from emerging on social media. The studio can only do so much in controlling another people's feed when it comes to the movie franchise.

Some of the spoilers come from unexpected sources, like tie-in products for the Marvel film. An Instagram user shared a rough translation of upcoming LEGO sets for Avengers: Endgame that provides a few details into the story.

The user may have only revealed the number of pieces, prices, and titles but the latter is telling of what could happen in the movie. For example, Battle of the Assembled Avengers suggests the heroes have another major battle to deal with in Avengers: Endgame. The set piece is the most expensive at $100 and has 699 pieces.

Whether this battle happens with Thanos is anyone's guess at this point. It is unlikely though that Thanos is in any mood for another battle. After all, he has already hung his armor as an ominous scarecrow as shown in the trailer.

There have been speculations that the team has yet to face their greater threat when Mistress Death appears. Fans believe that Thanos and the Avengers will team up in Avengers: Endgame to defeat Death.

Meanwhile, Captain America: Attack on the Outrider hints a minor battle for Captain Steve Rogers, with the LEGO set only at $20 and with just 167 pieces. The War Machine Crusher set, on the other hand, hints at a new suit for Tony Stark's friend and the Iron Man Armor Room set suggests the introduction of new Iron Man suits for the billionaire philanthropist. One of these suits might just save the Avenger from floating helplessly in space in Avengers: Endgame.

Lastly, the Avengers Super Quinjet LEGO set suggests the Avengers aircraft might be getting an upgrade in Avengers: Endgame. This set is the largest next to the Battle of the Assembled Avengers with 832 pieces for $80. The upgraded Quinjet could be the survivor's ride when they decide to travel back in time to save those who died from The Decimation. Speculations have it that time travel is the answer to undoing the Thanos snap that killed 50 percent of the human population in Avengers: Infinity War.
