Origin
The daughter of the Olympic god Zeus and the archeologist Helena Sandsmark, Cassie became a superhero despite her mother's objections.

"Borrowing" mystical devices not being used by Wonder Woman, she unleashed her super-human powers, and helped Amazon champion defeat a clone of the living weapon Doomsday.

Summoned to Mount Olympus by the gods, Cassie petitioned Zeus for super-powers of her own.  Impressed with his daughter's courage Zeus granted Sandsmark's wish.  Empowered, but unaware that the Olympic god was her father, Sandsmark returned to Earth assuming the role of Wonder Girl.
