Falcon (Marvel Cinematic Universe)

Samuel Wilson (AKA Exo-7 Falcon) is one of the main protagonists introduced in the Marvel film Captain America: The Winter Soldier.

In Captain America: The Winter Soldier
Samuel Wilson was once a retired paratrooper for rescue missions while serving in the military, but now works in the VA in Washington, DC as a counselor for people who suffered from Post-Traumatic Stress Disorder.

One day, while jogging, Sam meets and befriends Steve Rogers. Much later, Sam provided shelter for Steve and Natasha after being attacked by SHIELD soldiers, who are actually revealed to be working for HYDRA. After deciding to accompany Steve and Natasha to stop the reviving HYDRA from nefarious plans of world takeover, they kidnap the HYDRA agent Jasper Sitwell, but was ambushed by other HYDRA soldiers and the Winter Soldier. After the ambush, Sam, Steve, and Natasha were taking into custody by HYDRA soldiers (masquerading as SHIELD soldiers) but was freed by Maria Hill (Cobie Smulders). After discussing their plans to stop HYDRA, while taking shelter in a nearby dam, Sam, Steve, and the rest of the crew goes into SHIELD HQ. After Steve reveals the truth about SHIELD being taken over by HYDRA to the whole HQ and have the 3 Helicarriers launched early, Sam invaded the Bravo Helicarrier and Steve invaded the Alpha Helicarrier to put in the chips to have the Helicarriers target and destroy each other. After successfully doing that, Sam and Steve invaded the Charlie Helicarrier, but was attacked by the Winter Soldier. After the Exo-7 Falcon Jetpack was destroyed and thrown into SHIELD HQ, while Steve takes care of the last Helicarrier, Sam tries to fight against the HYDRA soldier Brock Rumlow, but was no match for him. When the Helicarriers have opened fire against each other and one of them crashed against the SHIELD HQ building, Sam barely escaped from the destruction and was rescued by Nick Fury and Natasha in the helicopter.

After the battle, Sam visited the injured Steve in the hospital, waiting for him to recover. After Steve's recovery, while visiting Nick Fury's "grave", Sam decided to accompany with Steve to find the Winter Soldier, who is revealed to be Steve's long-lost friend Bucky Barnes, thus ending the film.
