The only hero who is a legacy of himself. Fought the good fight in WWII and then was frozen. Thawed out in the present and has eclipsed his own rep from WWII which is impressive in itself. Since he's been thawed he's been a nigh constant Avenger. He is the team's heart, soul, and icon. No one represents us better.
Captain America is the steward and defender of the best ideals of man. He's goody-goody with out bugging you about it.
"And now I'm calling all citizens from all over the world, this is Captain America calling (calling)!" - The Kinks
"Captain America, is that you? Flying down the highway in your red, white, and blue!" - Styx
Cap is a skilled martial artist, acrobat, and military leader. He is considered one of, if not the greatest, Metaunit tactician (i.e. small teams of superhumans). He's an excellent motivator and skilled in creating a team that's greater than the sum of its parts.
Classic Costume, Blue pants, blue chest and shoulders, white arms, red boots and gloves and the vertical striped red and white. Wings on his head. All this and he looks cool Damit.
