In its later years, Overwatch was hit with a series of allegations resulting in high-profile mission failures, corruption and mismanagement, weapons proliferation, human rights abuses and more. These issues led to worldwide protests against the once beloved Overwatch yet they still fought the protect the world.

After being inspired by mankind’s ingenuity, Winston, the hyper-intelligent ape, escaped the Lunar Horizon Base and went to Earth to further his scientific pursuits. Lena Oxton, aka Tracer, was one of Overwatch’s youngest pilots and helmed the experimental, teleporting Slipstream aircraft. An accident forced Tracer to be desynchronized from time. Winston developed a chronal accelerator, which kept Tracer tethered to the present. Her chronal accelerator also allows her to control time around her with the ability to blink forward or rewind her presence in time.

Despite negative public opinion, Overwatch still remained active. Most world leaders looked down on Overwatch and didn't allow them to operate in their countries. This was true for England when Null Sector, an extremist group that fought for omnic rights, attacked London. Despite not receiving authorization to operate in the country by the Prime Minister, Jack Morrison authorized the deployment of agents in England, including Tracer. This would be her first official ground mission as an Overwatch agent. Despite sticking to their mission, a rift began to form between Reyes and Morrison.

In an effort to deal with the terrorist organization called Talon, members of Overwatch were tasked to bring them down. One of those agents was Gérard Lacroix. Because he was one of the lead agents in charge of bringing down Talon, he was the subject of numerous failed assassination attempts. To combat this, Talon kidnapped and brainwashed his wife, Amélie. The organization turned her into a sleeper agent and returned her to Gérard. Days later, she murdered him in his sleep. She disappeared back to Talon and the world presumed that Amélie Lacroix was dead. Soon, she would undergo more conditioning that altered her physically and mentally, turning her into the literally cold-blooded assassin codenamed Widowmaker.

On a mission with her team, Ana Amari was scouting for her team. They were engaged by the enemy, and Ana protected her entire team from afar, disposing of other snipers. Unfortunately for her, the final sniper ended up being someone she didn't expect, Amélie Lacroix. Ana was shocked to see Amélie on the battlefield, and the moment of hesitation cost her the mission. Amélie shot Ana, wounding her eye. Because Ana was knocked out, her entire team was wiped out and Overwatch presumed her dead. Due to her guilt, Ana hide from the world while she recovered.

With Ana gone, the fighting between Reyes and Morrison finally came to an explosive conclusion. In the middle of a United Nations investigation against Overwatch, a fight broke out at the Overwatch Swiss headquarters. The fighting triggered an explosion that destroyed the facility, and apparently took Reyes and Morrison into the inferno with it.

After the destruction of Overwatch headquarters, the presumed deaths of Reyes and Morrison and the investigation from the United Nations, the final nail in the coffin was the Petras Act. This act declared that any actions done in the name of Overwatch would be considered a crime. Overwatch agents around the world went dark.
