From infancy, Albrecht Krieger was fed a so called "miracle food" secretly developed by his father Siegmund. This substance made Albrecht super strong, incredible agile and incredibly intelligent. Unfortunately, it did not make him invulnerable, for he was wounded in a fencing duel while in school at Hedelberg, gaining a livid scar across his face.

When Hitler came to power in Germany, Siegmund Krieger presented his son to him as the ultimate development of the superior arayan race. Impressed, Hitler dubbed Albrecht Krieger Captain Nazi and had him smuggled into the United States as a weapon against American Superheroes.

Indirectly responsible for the creation of Captain Marvel Jr, Captain Nazi became his arch foe, going into seclusion at the end of the Second World War to plan his own world conquest.

When he learned that Captain Marvel and the rest of the Marvel Family had been trapped in suspended animation, Nazi placed himself in suspended animation as well, in a capsule timed to open when the Marvels were free once more.
