An awesome fan poster exploring what a Secret Invasion movie for the Marvel Cinematic Universe would look like turns Iron Man (Robert Downey Jr.) into a Skrull. Marvel Comics' Secret Invasion storyline is one of the most well-known the company has churned out in recent memory, and fans have been interested in a potential film adaptation for years. The limited run explored the idea that Skrulls, shapeshifting aliens, had secretly infiltrated Earth by posing as various influential figures. Those figures included several Marvel heroes, which led to a general feeling of paranoia as fans didn't know who was a Skrull and who was themselves.

Last year's Captain Marvel introduced Skrulls to the MCU, though the film twisted the script around and made the Skrulls victims of the Kree's cruelty. The Skrulls weren't the villains, and Captain Marvel herself (Brie Larson) ended the film by helping them find a new home in the far reaches of space. The Skrulls' leader, Talos (Ben Mendelsohn), later resurfaced in the post-credits scene of Spider-Man: Far From Home, when it was revealed he had been posing as Nick Fury (Samuel L. Jackson) for the entire film. This more than anything else seemed like a set-up for a Secret Invasion-esque storyline, as did the mention of Kree sleeper cells from earlier in the movie.

Marvel hasn't officially announced any intention to develop Secret Invasion for the big screen (or small screen via Disney+, for that matter), but that hasn't stopped fans from crafting their own ideas. Reddit user spideyvegas shared a poster for Avengers: The Secret Invasion that unites all the heroes expected to appear in Marvel's Phase 4 and beyond, from Captain Marvel to Black Panther (Chadwick Boseman). The really appealing hook of the poster, however, is Iron Man's presence. Iron Man tragically died in Avengers: Endgame, but this poster shows how a version of him could return to the MCU: As a Skrull. See it for yourself below:

Downey's time came in the MCU to an end with Endgame, but some still hold out hope that he could reappear further down the line. For example, rumors have been swirling for months that he could make a cameo in Black Widow, though nothing has been confirmed. Downey himself wasn't willing to completely write off a future return to the MCU, though if it ever happened, it would likely be a long time from now.

Now that the Infinity Saga has come to a close, Marvel is likely looking for its next big event. While The Avengers 5 is still far away, it's assumed that the movies of Phase 4 will plant the seeds for whatever is to come, similar to how Phase 1 set up the future arrival of Thanos (Josh Brolin) and the Infinity Stones. It would make sense for the MCU to adapt Secret Invasion now that they've brought Skrulls into the universe, but there's no guarantee that they will, or that Iron Man will somehow find his way to the center of the story.
