Captain America (Avengers Assemble)

Steven Grant Rogers is a World War II veteran, superhero, and founding member and second leader of the Avengers. Born in Brooklyn, New York City, the young Rogers had suffered from numerous health problems and upon America's entry into World War II, was rejected from military service despite several attempts to enlist. Determined to serve, he ultimately volunteered for the top-secret Super Soldier program, and the frail Rogers was then enhanced to the peak of human perfection. Rogers soon joined the war effort and was given the new moniker of Captain America.
