The Avengers: Earth's Mightiest Heroes Wiki

President Franklin D. Roosevelt was the President of the United States during World War II.

He is presumed to be deceased after the war.

Black Panther revealed to his fellow Avengers that his father T'Chaka had gave a piece of vibranium as a gift to President Roosevelt as a sign of friendship between America and Wakanda, which Dr. Myron MacLain used on his experimental iron alloy that creates Captain America's shield.
