As the culmination of a decade-plus of Marvel Cinematic Universe storytelling, Avengers: Endgame had quite a lot of characters to feature and evolve. The nature of the Endgame's costumes was debated about quite a lot in the time leading up to the film's release, as fans were eager to see what Earth's Mightiest Heroes would be wearing in the fight against Thanos (Josh Brolin). In the case of James "Rhodey" Rhodes (Don Cheadle), that nearly involved a few different suits of War Machine armor. The recently-released Marvel's Avengers: Endgame: The Art of the Movie book reveals that Rhodey was initially supposed to wear three different armors throughout the film, each of which would have had a different significance on the plot.
