Samuel Thomas "Sam" Wilson, better known as Falcon, is a former United States Air Force para rescue airman who left active duty when his wing-man Riley died in combat, choosing instead to begin helping any of his fellow veterans who were suffering from post-traumatic stress disorder at Veterans Affairs.
Real Name: Samuel Thomas Wilson
1. Captain America: The Winter Soldier
During this time, Wilson met and soon became an ally of Captain America during the beginning of the HYDRA Uprising, assisting him in bringing down Alexander Pierce's schemes for Project Insight before then choosing to remain with Captain America for future missions.
While the Avengers brought down the remains of HYDRA, Falcon assisted Captain America in his search for Bucky Barnes in order to try and save him from the brainwashing which turned him into an assassin.
2. Avengers: Age of Ultron
Following the events of the Ultron Offensive, Falcon was recruited into becoming a member of the second incarnation of the Avengers, during which time he continued his search for Barnes and had an encounter with Ant-Man who was attempting to break into the New Avengers Facility, which had led Wilson to consider recruiting Ant-Man into the Avengers as an asset.
3. Captain America: Civil War
Falcon continued to be an active member of the Avengers, also managing to successfully stop the schemes of Crossbones, until Wilson chose to side with Captain America in violation against the newly formed Sokovia Accords. Believing in his friend and leader, Wilson then assisted him in rescuing the Winter Soldier from the government's Joint Counter Terrorist Centre as they tried to expose Helmut Zemo as the true villain.
This resulted in Falcon fighting against his former team mates when Iron Man attempted to stop them. In the aftermath of the battle, Wilson was arrested by Thaddeus Ross and taken to the Raft along with his teammates, but was soon freed by Captain America as they were forced to become vigilantes on the run.
4. Avengers: Infinity War
Wilson was soon thrown into another situation when Earth was attacked by Thanos who sought to claim the Mind Stone embedded in Vision. He joined the Avengers who defended Wakanda. However, while they killed Thanos's forces, they were completely overpowered when Thanos personally came. Wilson alongside T'Challa, Barnes and Groot were all disintegrated, along with the rest of half the life in the universe.
5. Avengers: Endgame
Eventually, that Snap was undone by the surviving Avengers, as Falcon rejoined their battles against Thanos, as they finally defeated him, at the cost of Tony Stark's life.
In the aftermath of the battle, Falcon learned that Captain America returned to the past and had lived a full life with Peggy Carter, seeing him return as an old man, and passed his shield down to Falcon.
