Avengers: Endgame's New Suits Debut - But Likely Not For the Quantum Realm

Avengers: Endgame

The surprise new trailer for Avengers: Endgame is packed with plenty of surprises, from a sentimental look at key character moments from the Marvel Cinematic Universe to a team-up between Rocket Raccoon and War Machine. But perhaps what was most dramatic sequence is the official debut of the heroes' mysterious "Advanced Tech" suits.

First revealed in October on toy packaging, the suits have sparked plenty of speculation, despite the assertion by Endgame co-director Joe Russo that "99 percent" of such leaks are inaccurate. Now, however, we have proof that the remaining Avengers indeed don the suits in the highly anticipated sequel. The only question is, for what purpose.

Popular theories have suggested the Advanced Tech is used to enter the Quantum Realm, featured so prominently in Ant-Man and The Wasp, or to travel through time. The answer, however, may be much simpler: If the trailer and the clues are any indication, the Avengers will venture into space.

We already know that Thanos will remain a focus of Endgame. Now that he's succeeded in his goal to achieve balance in the universe, by wiping out half of all life, he has no reason to return to Earth. The only hope the heroes have of defeating the Mad Titan and saving the universe likely will be to confront him, wherever he may be. It's probably no accident the Avengers are essentially doing their own take of The Right Stuff astronaut walk. More than likely, it's because they are preparing to leave the planet.

What's more, while we see most of the heroes in these new suits, Thor and Captain Marvel aren't shown in the sequence. That may be because the two powerhouses are busy elsewhere. However, it could also be that they don't require any special tech to survive in space. And, sure, we don't see Rocket either, but he's so short he may simply be out of frame.

That Scott Lang is also wearing one of the suits further suggests space as their destination: He's traveled into, and out of, the Quantum Realm in his Ant-Man costume, so why would he require this other tech now?

Finally, we turn to the comics. In the Infinity event, which served as partial inspiration for Avengers: Infinity War, Captain America took a team of Avengers into space to confront a threat. The heroes wore their respective costumes, only modified with an extra layer of advanced armor. While in the comics they battled an ancient alien race known as the Builders, Endgame could could easily use that as inspiration to take the Avengers into the galaxy for a final battle against Thanos.
