The Marvel Cinematic Universe Phase 4 is starting another Civil War with The Falcon and The Winter Soldier. Even though Steve Rogers' MCU story is done, the franchise is still continuing some of the storylines he was part of. This includes Sam Wilson and Bucky Barnes' Disney+ show dealing with Captain America's legacy and building off the unresolved nature of Captain America: Civil War. The Phase 3 film introduced the Sokovia Accords and split the Avengers apart, only for them to regroup a few years later.

Sam and Bucky are no longer fugitives when The Falcon and The Winter Soldier begins but their actions might be leading to another superhero rift. Captain America's former sidekicks teamed up again in episode 2 and quickly found themselves fighting with Steve's replacement. John Walker's Captain America and his sidekick Battlestar help Sam and Bucky at first, but it doesn't take long for Falcon and Winter Soldier to reject their help. By continuing to push Captain America and Battlestar away, The Falcon and The Winter Soldier is setting up a battle between two different types of heroes.

The end of The Falcon and The Winter Soldier episode 2 saw Walker help get Bucky out of an arrest and try once more to convince Bucky and Sam to team up with him. However, they reject his offer, with Sam noting that they are "free agents" in the superhero game who don't answer to anyone. This doesn't sit well with Walker who then threatens them to stay out of his way. The obvious friction between Sam and Bucky and Captain America and Battlestar appears to set up The Falcon and The Winter Soldier making Civil War 2 about regulated vs unregulated heroes.

Regulated heroes vs unregulated heroes can be how Phase 4 tackles the same idea of Captain America: Civil War but in a slightly new way. The Phase 3 movie focused on the difference between heroes who registered with the Sokovia Accords and those who didn't. This created a great divide in the Avengers, but there wasn't much exploration of the consequences of these decisions. With Sam and Bucky now seemingly following in Steve's footsteps to avoid oversight by anyone with their own agenda, The Falcon and The Winter Soldier can revisit this topic if its lead characters' actions are not sanctioned by the government. This could even lead to Sam and Bucky no longer being able to get help from Joaquín Torres and the Air Force.

If The Falcon and The Winter Soldier is the start of a Civil War 2 story in Phase 4, this idea could be part of other movies and Disney+ shows. Hawkeye could deal with Clint Barton and Kate Bishop having to choose how they'll operate as heroes. She-Hulk could see Jennifer Walters battle the elements of regulating heroes in court, and Armor Wars could see War Machine attempt to clean up who is using Tony Stark's technology. Of course, a Civil War 2 story will also surely affect how Sam and Bucky's stories conclude in The Falcon and The Winter Soldier. Sam might decide to become a regulated hero to take back the Captain America mantle or make the bolder move to have Cap operate on his own. All of this could even lead to a future movie, such as Captain Marvel 2, being a loose Civil War II adaptation.
