Avengers: Endgame concept art reveals an early design for the time travel suits. Five years following their devastating loss to Thanos (Josh Brolin) in Avengers: Infinity War, the surviving heroes banded together in the hopes of bringing back those who disintegrated into dust via the snap. This required them to travel back in time to collect all six Infinity Stones and create their very own Infinity Gauntlet. The trip called for new mechanics to make time travel possible, like the Quantum Suits worn by the Avengers.
Between Hank Pym’s (Michael Douglas) Quantum Realm research and Tony Stark’s (Robert Downey Jr.) wrist device that allowed them to visit certain points in the MCU’s history, the team found themselves traveling back in time. This new mission called for time travel suits that helped them survive their deep dive into the Quantum Realm. Like Iron Man’s armor, the suits are made of nano-tech, making it easier to get in and out of them. This was the first time that the Avengers got something as close to a uniform and they will forever be associated with Endgame. However, before directors Joe and Anthony Russo decided on the sleek looking, red and white costume, there was an early version of it the suits that looked very different.
Digital artist Aleksi Briclot shares a concept art he created for Endgame‘s Quantum Realm suits which is very different from what ended up on the big screen. For starters, it’s colored yellow, not red and white. It’s also much bulkier and it’s headpiece is reminiscent of an astronaut’s helmet. According to the creator, this was inspired “by elite pilot like those from Sr71, you know the Lockheed Blackbird also used by the Xmen.” Check out the images below:
At this point, it’s difficult to imagine the Avengers donning this or any kind of time travel suit other than the ones they wear in Endgame. The red and white version was a mix of Pym and Stark aesthetics, which makes sense considering they are the two major brains behind making time travel possible. When the suit design was initially revealed to the public with almost no context, fans were quick to point out that it resembled the suit Hank wore to save Janet van Dyne (Michelle Pfeiffer) from the Quantum Realm in Ant-Man & the Wasp, giving them the idea that it might be for an exploration of the alternate dimension. Marvel Studios Head of Visual Development Ryan Meinerding revealed a dark version of the suit which admittedly looked sleeker, implying that once the Russos decided on the look of the armor, they pretty much stuck to it.
Avengers: Endgame not using the aforementioned design was ultimately for the best because of a couple of reasons. Mining style inspiration from Pym’s previous suit visually established his contribution in making the time heist possible. Yellow matching superhero uniforms are also associated with the X-Men – as pointed out by the artist himself. Chances are that when the illustration was made, news of the mutants coming to the MCU was still unknown. Regardless, it’s safe to assume that Marvel Studios wanted something distinct to the Earth’s Mightiest Heroes, especially considering that they rarely get uniforms.
