The Marvel Civil War meme stems from the promotional material and dramatic confrontation in the 2016 MCU film, Captain America: Civil War. The primary template features Steve Rogers and Tony Stark standing face-to-face, symbolizing the ideological split between the Avengers. Internet users adopted this format to highlight hilarious or trivial conflicts, ranging from pineapple on pizza to console wars. By placing contrasting opinions over each hero, the meme humorously elevates everyday arguments to the scale of a superhero epic.
