10 Mind-Blowing Facts You Didn't Know About Captain America

Although fans are excited to see Sam Wilson as the new Captain America in The Falcon and the Winter Soldier, he's not the first person to replace Steve Rogers.

When Rogers was seemingly killed during WWII, William Nasland was assigned as the new Captain America to maintain his legacy. After being mortally wounded, Nasland officially passed the mantle to Jeffrey Mace.

Rogers eventually returned but gave up his superhero lifestyle when he lost faith in his country. As a result, a soldier called John Walker became the new flag-waving superhero. Rogers believed Walker was too brutal for the role and forced him to step down, reclaiming the mantle for himself. (Walker would later adopt the title US Agent, and serve as an anti-hero in further stories.)

Years later, Rogers learned that he wasn't the first person injected with the Super-Soldier Serum. An African-American called Isaiah Bradley was injected with a prototype of the Serum. Even though the procedure worked on Bradley perfectly, the government forced him into hiding, saying America wasn't ready to see an African-American representing their country.

Of course, the most famous alternative Captain America has to be his sidekick, Bucky. When Rogers infamously died in the Civil War, Bucky donned the shield to pay tribute to his mentor and continue his mission to vanquish all evil. Steve later returned, but was replaced yet again by old ally Sam Wilson, who has once again assumed the title of The Falcon with Rogers remaining as Captain America.
