It’s the most secretive film in movie history, but merchandise for Avengers Endgame was always going to tease a few titbits. One Marvel fan has posted pictures from a toy shop of characters from the movie. He’s even tweeted: “The store (where these photos were taken) was asked to put these toys back to storage.” WARNING POTENTIAL SPOILERS FOR AVENGERS ENDGAME AHEAD.
Firstly the dolls in question show surviving superheroes like Hulk, Thor, Black Widow and Rocket in identical white Avengers suits.
While these could just be for team purposes, they’re also rumoured to be Quantum Realm travelling suits.
After all, the Avengers Endgame trailer appeared to tease Ant-Man’s arrival with the Quantum Tunnel van as being the key to defeating Thanos.
Our best bet is the Avengers will time travel through past MCU films to gather the Infinity Stones before Thanos did in Avengers
