Cassie Sandsmark is the daughter of Dr. Helena Sandsmark, a noted archeologist who had worked with Wonder Woman before, and the Greek God Zues. She would later gather magical equipment from Greek Gods and help Wonder Woman on several occasions. Eventually Cassie asked Zues for real powers, and Zues granted her the same powers as Wonder Woman, but giving her mother the ability to take away these powers at any time. Her mother rarely uses this power, supporting the fact of her daughters heroism. She idolized the original Wonder Girl, Donna Troy, and wore a black wig in her original costume as a way to disguise her true identity. Later she changed the costume to look more like Wonder Womans and she took up the identity Wonder Girl.
