Captain America: the First Avenger (1981)

Mcu 30 Years Earlier

Steve Rogers, a weak, sickly young man eager to fight is repeatedly rejected from the war-until a seemingly "crazy" scientist recruits him in a new experiment to turn the tides. He is transformed into the super soldier the world needs, but no one believes it. He is used as an empty face for propaganda until his comrades, including hid best and only friend, are captured by the Red Skull, a Nazi general who wants to use the Tesseract for evil. "Captain America" breaks into Red Skull's HQ with the help of Peggy Carter and Howard Stark, and Captain America saves everyone. And everyone begins to realize what Captain America can really do.
