An old, rotund man named Dudley, Uncle Marvel did not have any real superpowers. He found Mary Batson's good deed ledger which she kept to record her good deeds but had dropped and read it, learning her secret. Claiming to be the uncle of Mary Batson, Mary Marvel's teenage alter-ego, from California, Dudley attempted to con his way into the Marvel Family. The Marvels, possessing the wisdom of Solomon, saw through Dudley's machinations, but since he was, in their opinion, such a "lovable old fraud," they allowed Dudley to join the team as their manager, Uncle Marvel, and humored his pretense of having Marvel powers. When asked to make use of his supposed superpowers, Dudley would always complain that his "shazambago" was acting up and was interfering with his powers, though the Marvels always knew better.

A young woman, Freckles Marvel, claimed to be his niece.
