How old is Captain America when he receives the 'Super-Soldier Serum'?
Steve Rogers is said to have been born in the 1920's. WWII started roughly in 1939 with the invasion of Poland by Germany. Rogers attempts to enlist in the US Army in 1940, however due to his frail physical state he is denied entry.
Having been observed by certain key Army officials attempting to enlist several more times after being denied, he is inducted in to Project Rebirth as its first candidate for Dr. Erskin's Super-Soldier Serum. After receiving said serum, and becoming the pinnacle of human potential he operates in the European theater of war for several years alongside Bucky Barnes and, on occasion members of the Invaders.
On his final mission during the war he and Barnes are presumed dead when the experimental bomb they are attempting to stop from destroying Washington DC explodes dumping Cap in the Arctic waters to be frozen and preserved for many years before he is found and revived by the founding members of the Avengers.
I'm trying to figure out how old he was when he received his serum treatments and became Captain America, and/or how old he was when he was frozen in the ice.
This is flatly contradicted by the film version which states that he was born on July 4th, 1918 and turned into a superhero aged 21.
Both versions agree that was frozen in 1945 (aged 25 and 27 respectively).
@Monty129 - Geddit?! He was born on July 4th, just like America!! I bet Stan Lee slapped his knee when he thought of that one.
I was going to correct you by pointing out that Joe Simon and Jack Kirby *originally* created Cap, but the cornyness of that date leads me to believe that only mr "Excelsior!" himself could have come up with that part.
@Monty129 This was in an era where he regularly punched Hitler in the face. And you think him being born on July 4th is the odd contrivance?
For what it's worth (not much probably) this change was probably made so that Steve's father could die from "Mustard gas." If he had been born in 1920, he would've been conceived in 1919, after the war was over.
@Dave - I assumed it was because 30 year old Chris Evans couldn't conceivably play a 20 year old. Making him 22 makes it a smidge more believable.
Given what they accomplished with his 90 lb weakling body, I doubt removing a few lines/adding some baby fat to his face was a big concern.
