Cassandra "Cassie" Sandsmark, also known as Wonder Girl, is a superheroine appearing in DC Comics. She was created by John Byrne and first appeared in Wonder Woman (vol. 2) #105 (January 1996). The second Wonder Girl, Cassie is a sidekick of the superheroine Wonder Woman and has been featured as a member of the Teen Titans.^[1]

When Cassie was introduced, she was the daughter of an archaeologist, Dr. Helena Sandsmark, a friend of Wonder Woman's. To help Wonder Woman during an adventure, she borrowed magical artifacts which bestowed upon Cassie superpowers, with which she fought crime as Wonder Girl. Later, Zeus, king of the Greek gods, grants her real powers. Later revelations showed that Cassie was in fact a demigoddess and the daughter of Zeus and Dr. Sandsmark.^[2] In 2011, when DC relaunched Wonder Woman and revealed she was Zeus's daughter, the publisher retroactively changed Cassie's backstory to establish she was actually Zeus's granddaughter, making her Wonder Woman's niece.^[3]
