William Burnside
William Burnside idolized Capt. America during his growing year and even went on studying his adventures. While conducting research in Germany in 1950, Burnside came across records of Captain America and the formula for Super Soldier Serum. Burnside refused to hand over the formula to US government unless they made him the new Captain America.
Burnside also underwent plastic surgery just to look like Captain America. Gradually the Super Serum formula started to decay affecting Burnside mentally. He was eventually arrested and later came to be known as the Grand Director.
Roscoe Simons
Steve Rogers gave up his title as captain America during the reign of President Richard Nixon and was named Nomad. He was under the illusion that the president was running a secret terrorist organization.
Steve passed on his shield to Roscoe Simons, who was trained by Falcon. Concerned with Simons safety Falcon persuaded him to give up the title. His end came violently as Simons was killed by Red Skull. Simon’s death inspired Steve to regain his title.
