When Marvel fans ask themselves which Avenger is the most likely to die in Avengers: Endgame, most automatically think Captain America. But could fans be shocked by an early death of the Cap in Endgame? A new theory says we could say goodbye to Steve Rogers right in the beginning of the film.

The theory, floated by ComicBook.com, stems from teasers from Endgame where Captain America seems to be fighting Thanos from a raised location—perhaps at the Avengers H.Q. in New York, the Nova Corps-ruled Xandar, or even in the midst of the Battle of New York.

Captain America's death could be featured in this scene, which will likely come in the first act of the three-hour movie. This would definitely set the tone for the film, and his death would finally get the rest of the Avengers together and spur them into action against the Mad Titan Thanos.

But it won't just be the Captain's life they'll set out to avenge. It'll be all the other fallen who died from Thanos' snap in Infinity War. And since most fans are sure that the team will eventually use the Quantum Realm to time travel, maybe they'll come across a previous Captain America who will help them out.

It is an interesting theory, and one that could actually pan out (sadly), but we won't know for sure until the film premieres on April 26.
