John F. Walker - the U.S. Agent

After Steve Rogers retired as Captain America, and Sam Wilson returned the shield, the US government sought a new patriotic hero. John Walker, a highly decorated veteran with exceptional physicals, was chosen as the new Captain America. Despite embracing the role, he struggled with its pressures, leading to a public incident where he killed a terrorist. Stripped of his rank and shield, Walker eventually allowed Sam Wilson to become the new Captain America, while he forged his own path as the U.S. Agent. Spoilers for The Falcon and the Winter Soldier.
