Marvel revealed why War Machine became Iron Patriot for a little while in the MCU. The Wakanda Files shows that the President had some concerns about the branding of the “borrowed” Iron Man suit after Iron Man 2. He suggests the Department of Defense adopted a new moniker for James Rhodes’ armor. Iron Patriot made a fun entrance inIron Man 3 but quickly ended up being cast aside for the more traditional War Machine name later on. When that version of the suit showed up in Avengers: Endgame, it was a moment that threw some fans off. It made sense after some comments from the directors and screenwriters. A lot of fans believe that the armor will end up in some enemy hands down the line in the MCU but nothing has been alluded to so far.
