<P> "Captain America" is the name of several fictional characters appearing in American comic books published by Marvel Comics . The first, and main, character was Steve Rogers, who was created by Joe Simon and Jack Kirby . Other characters have adopted the alias over the years and following Rogers' death his former sidekick James Buchanan Barnes (Bucky) picked up the mantle . Late 2010s storlines have his sometime crime fighting partner Sam Wilson assuming the role . </P> <P> Captain Steven Rogers, the 18th century ancestor to the World War 2 Super-Soldier serum recipient . He wore a colorful costume same as his descendant and carried a round cast iron shield as shown in Captain America: Sentinel of Liberty #6 (March 1999). But Revolutionary War Rogers acted as such before the USA existed formally as an independent country . Thus, while addressed as "Captain America", Revolutionary War Rogers is largely not considered part of the formal line . </P> <P> Steve Rogers was a scrawny Army reject who was given the Super-Soldier serum, becoming the only complete success for Project: Rebirth, and the first formal person to be termed as "Captain America" as created and controlled by the Marvel Universe USA government . </P> <P> As depicted in the 2003 limited series Truth: Red, White & Black, the World War II Super Soldier program of 1942, which used African American test subjects to re-create the formula that had been used to turn Steve Rogers into Captain America . The clandestine experimentation that empowered Isaiah held similarities with the Tuskegee Syphilis Study . Considered to be the "Black Captain America", Isaiah Bradley became an underground legend among much of the African - American community in the Marvel Universe . Isaiah is also the grandfather of Elijah Bradley (aka Patriot). </P>
