In 1940, patriotic young American Steve Rogers volunteers for the Super Soldier Project, run by Dr. Josef Reinstein. Rogers is injected with a prototype serum and subjected to “Vita-Rays”. The procedure is an unprecedented success and the subject quickly develops muscle mass, unusual endurance, and improvements to his reflexes that make the formerly 4-F Rogers into a true super soldier.
The Super Soldier procedure is immediately mass produced and administered to over 200,000 American soldiers by 1942, when American super soldiers capture Berlin, and Imperial Japan surrenders rather than face the humiliation of her military being brushed aside by a relative handful of “Choujin”.

In a strange turn of events, his corpse is discovered encased in an iceberg two decades later.
