Captain America

"I can do this all day."- Captain America, The Avengers (2012)

Captain America is a American superhero in the MCU. The original Captain America was Steve Rogers who had retired. The next Captain America is Sam Wilson. He had a partner named Bucky Barnes aka The Winter Soldier. Sam Wilson was originally called The Falcon. He is also a member of The Avengers. As Falcon continued searching for the Winter Soldier, he was then recruited into the Avengers, since their original team had been disbanded following the defeat of Ultron. During his time with the Avengers, Falcon briefly encountered Ant-Man before assisting in defeating Crossbones. In the aftermath of several battles that had killed civilians, the Avengers were then forced into following the Sokovia Accords, putting them all under the government's full control. However, as the Winter Soldier was blamed for terrorist attacks by Helmut Zemo, Falcon stood by Captain America with protecting the Winter Soldier, which had then caused the Avengers Civil War. In the wake of this clash, Falcon, and several other Avengers who were loyal to Captain America, were defeated by Iron Man, and locked into the Raft, until Captain America freed them as they became fugitives.
