Captain America Civil War 4-Pane, also called Captain America vs Iron Man, is a stack of four vertical screenshots pulled from the 2012 Marvel film The Avengers, where Steve Rogers and Tony Stark trade jabs across a lab table2. Cap voices a position in the top pane, Iron Man snaps back below, and the two glare at each other in the closing frames, giving the format a natural setup and payoff rhythm.

Editors treat the panels as an exploitable, swapping the original dialogue for whatever petty argument they want to stage between two hardened camps, from console wars to shipping debates1. The joke works because the acting already reads as two people who will not budge, so any low-stakes disagreement dropped into the captions instantly looks like it deserves a superhero showdown2.

Creators typically keep the four vertical panels intact and rewrite only the dialogue captions. Cap gets an earnest or mild opinion in the top pane, Iron Man fires back with the opposing take, and the bottom two panels stay wordless so the actors' scowls carry the payoff. Common topics include console loyalties, ship preferences, and franchise fandom feuds.
