Currently living a double life as Captain America and an architect, Steve Rogers' origin is recounted in great detail. He grew up a hard-worker on New York's lower east side. When World War II broke out, he volunteered for the army, but was rejected due to poor health. A top-secret military project took notice of him and made him a test subject. Fortunately, the test was successful, and Steve became Captian America.
When young "Bucky" Barnes discovered his secret identity, Cap made Bucky his costumed sidekcick. They spent the war fighting on the front lines and busting spy rings, until a tragic accident...
Cap was awoken years later to become an Avenger, and he doesn't regret a single thing.
