Captain Marvel
In the original Fawcett and DC continuity, Captain Marvel Jr.'s alter-ego was Freddy Freeman, a disabled newsboy saved by Captain Marvel from the villainous Captain Nazi. To save the dying boy's life, Captain Marvel shares his powers with Freddy. By saying the name "Captain Marvel", Freddy is transformed into Captain Marvel Jr., a blue costumed version of himself possessing powers of superhuman strength, speed, wisdom, and more. Junior derived his powers from Captain Marvel himself, while the other Marvels derived their powers from the wizard Shazam. Unlike Captain Marvel and the modern-era version of Mary Marvel, Junior remained a teenager in his transformed state.
