Team Cap may have lost the fight in Captain America: Civil War, but it is Team Iron Man who had the most tragic fate in the MCU. While the movie version of Civil War was not as big and long-lasting as the 2006 comic book arc, the clash between Captain America and Iron Man had both immediate and long-term consequences for the MCU. Eventually, the Avengers all reunited to fight Thanos – but the fact they were split at the beginning of Avengers: Infinity War is one of the reasons why Thanos managed to collect all the six Infinity Stones and perform the snap.
For being a Captain America movie, Civil War would naturally have to frame Iron Man and those who sided with him as the antagonist – at least during the first two acts of the movie. Similar to the comic book arc, the main reason for the fallout of the Avengers was the governmental project for the registration of superpowered heroes, which in the MCU was represented by the Sokovia Accords. As following MCU movies and shows did not dive into how the Sokovia Accords impacted the world, the major consequence of Civil War was how it split up the Avengers right as Thanos was heading to Earth – with team Captain America either having to turn themselves in or living as fugitives.
