10 Years Later: How Captain America: Civil War Reset The Entire MCU Before Avengers: Doomsday

by

May 6, 2026, will mark the 10th anniversary of Captain America: Civil War. While it was the third Captain America film, it really felt like a third Avengers movie because it focused on the team falling apart rather than being a typical solo adventure for Captain America. But it was more than just that—inspired by the comic book event by Mark Millar, this movie dramatically changed the Avengers, ultimately leading to Thanos’s victory in Avengers: Infinity War.

Both the comic books and the Marvel Cinematic Universe (MCU) featured a government response to a disaster caused by superheroes. In the comics, the New Warriors accidentally caused a deadly explosion, while in the MCU, it was the aftermath of Ultron’s attack. Both events sparked public fear about unchecked superpowers. As a result, a system for registering and controlling these individuals was proposed. Iron Man supported government oversight (through the United Nations in the MCU), while Captain America championed individual freedom.

The events of Captain America: Civil War left Iron Man and Captain America estranged and fractured the Avengers team – and this happened at the absolute worst moment. Captain America, Black Widow, and others were branded as criminals. When Thanos attacked in Avengers: Infinity War, the Avengers were still fighting amongst themselves, preventing them from uniting and stopping Thanos from eliminating half of all life. Ultimately, all of this stemmed from the conflict in Captain America: Civil War.

Civil War Deconstructed The MCU’s Two Biggest Heroes

Captain America and Iron Man were the core of the Avengers, especially when Thor and Hulk were unavailable. They repeatedly saved the world from disaster – Iron Man by stopping a dangerous terrorist group from using a powerful virus, and Captain America by defeating a secret takeover by Hydra and exposing a massive conspiracy within the U.S. government. Together, they truly stood out as the world’s most impactful heroes.

Each hero’s personal experiences also contributed to their growing distance. Iron Man, after building Ultron and seeing the devastation it almost caused, realized the danger of unchecked power. His past trauma from the alien invasion led him to believe that even the Avengers, including himself, needed to be overseen by the United Nations.

Captain America witnessed a disturbing truth: Hydra had secretly infiltrated and attempted to control the U.S. government. He saw how they took over SHIELD, a vital security organization with roots in a Nazi group. This raised a serious question: if Hydra could control the government and an agency meant to protect people, could superheroes really be trusted under their leadership? The situation had the potential to become disastrous.

In Captain America: Civil War, both Captain America and Iron Man had the same goal: to keep the world safe. However, they disagreed on how to do it. Iron Man thought superheroes needed to be controlled to prevent accidents, while Captain America believed governments weren’t always trustworthy and could misuse heroes. This fundamental disagreement led to a conflict between them, which became known as the Civil War.

Captain America: Civil War Splintered The MCU Heroes When The World Needed Them Most

Man, after Civil War, things got seriously messy. The government was after Cap, Widow, Scarlet Witch, and Vision because they wouldn’t sign those Sokovia Accords, so they basically had to disappear. Poor Ant-Man was stuck with house arrest. Tony, or Iron Man, was trying to keep things together with the remaining heroes, but then Hulk showed up out of nowhere and dropped this huge bombshell – Thanos was on his way! It was a total game changer, and you could just feel the tension building.

Despite the efforts of powerful heroes like Iron Man and Doctor Strange, Thanos’s first strike proved too strong. Black Panther and his army fought bravely, but couldn’t hold him back. Things only began to improve when the heroes stopped fighting amongst themselves and united against the common enemy. Unfortunately, they couldn’t maintain that unity, and quickly fell back into infighting, which led to their defeat. Even the arrival of Thor and the Guardians of the Galaxy wasn’t enough to turn the tide, and Thanos ultimately won.

It’s impossible to know if the Avengers, Guardians of the Galaxy, and the people of Wakanda could have defeated Thanos if they had joined forces earlier. A unified plan and cooperation could have stopped the Black Order. Unfortunately, they didn’t work together effectively, and by the time they finally fought alongside each other, it was too late. Ultimately, Thanos won, and this was largely a result of the divisions created by the events of Captain America: Civil War.

Captain America: Civil War Still Has Ripple Effects In Today’s MCU

By the time Avengers: Endgame arrived, Iron Man and Captain America had resolved their differences. They teamed up with the remaining heroes to bring back those they’d lost and defeat a new version of Thanos who wanted to destroy everything and start over. The events of Captain America: Civil War still had lasting consequences, and the world hadn’t fully recovered.

These days, people have lost faith in heroes. The government’s Damage Control department is actively tracking them down, even going after young heroes like Kamala Khan and those just trying to live normal lives, like Wonder Man. Anyone with superpowers is either being imprisoned or constantly monitored unless they agree to work for Damage Control as a controlled operative. When the X-Men arrive, the situation will closely mirror storylines from the comics.

The Disney+ series Secret Invasion ended with widespread violence, as people began killing anyone they suspected of being an alien, even going so far as to murder the British Prime Minister. Now, the government is creating new security measures to protect itself – not from outside threats, but from its own heroes. This shift reflects how drastically the world has changed since the events of Captain America: Civil War.
