Captain America (1968 series) #233

On a Harlem street, Captain America is caught between the forces of gang boss Morgan and his gunmen and the fanatical National Force—one of whom is the brainwashed Sharon Carter. Cap tries for a peaceful resolution but neither side will listen to reason; Cap’s only recourse is to fight both gangs to distract them from killing each other. Soon the National Guard arrives to restore order but when the commander tries to take Cap into custody, Cap disarms him and heads off. Not far away, the captive National Force gang members kill themselves with a touch of their belts; Cap tries to learn whether Sharon was one of them but no one can tell him….

Realizing that his only lead now is Peggy Carter, Cap heads to the hospital. As he passes his apartment, he is spied by a mysterious villain hiding inside who has just concluded that Captain America is Steve Rogers. Cap arrives at the hospital to discover that Peggy has been discharged and taken away—by a Dr Steven Rogers. Confused, Cap heads to the address listed, where the villainous mastermind Dr Faustus and the insecure Grand Director are setting a trap. Cap enters the building to be greeted by a robot double of Sharon Carter firing a machine gun; he destroys it, evades a booby-trapped elevator, then confronts illusions of the Red Skull and MODOK to come face-to-face with Dr Faustus. The villain easily punches out the hero who has finally succumbed to Faustus’ mind-gas—and the Grand Director unmasks as…Steve Rogers….
