Cassandra "Cassie" Sandsmark, a.k.a. Wonder Girl, is a fictional character, a DC Comics superhero. Created by John Byrne, and first appearing in Wonder Woman (vol. 2) #105 (January 1996), she is the half-human daughter of Zeus.
Cassandra Sandsmark initially appears as a supporting cast member in Wonder Woman. She later appears as part of an ensemble in Young Justice and Teen Titans. Without a series of her own, she has recently appeared in supporting roles in 52, Supergirl, and the relaunched Wonder Woman series. In September 2007, she appeared in the six-issue limited series Wonder Girl: Champion written by J. Torres and illustrated by Sanford Greene.
Cassandra is the third character to be called Wonder Girl; the second being Donna Troy, following the earlier stories of a young Wonder Woman using the name Wonder Girl. Cassandra is the daughter of Dr. Helena Sandsmark, (a noted archaeologist with whom Wonder Woman was working) and the Greek god Zeus. During a fight with a Doomsday clone and another battle with Decay, she created a costume and used magical accoutrements (the sandals of Hermes and the gauntlet of Atlas) to help Wonder Woman, much to her mother's horror. Cassandra later had the opportunity to ask Zeus for a boon, and requested real superpowers. Zeus granted her request, but gave Dr. Sandsmark the ability to deactivate them. Dr. Sandsmark, however, reluctantly accepted her daughter's wish to be a superhero and rarely if ever uses this ability.
Cassandra heavily idolized Donna Troy, the original Wonder Girl, and to that effect wore a black wig over her natural blonde hair (it also helped to conceal her identity). Donna gave Cassandra the second costume she wore as Wonder Girl, but Cassandra was afraid to wear it lest it were ruined. She has been trained by Artemis, the former "stand-in" Wonder Woman. As Wonder Girl, Cassandra joined Young Justice due to her crush on Superboy. She became close friends with Arrowette, Secret, and Empress. During her time with that group the dark god Oblivion caused Wonder Woman's Wonder Dome palace to destroy Gateway City. Artemis ordered Cassandra to help with crowd control instead of wasting time putting on her Wonder Girl disguise. Agreeing with her, Cassandra revealed her secret identity before news cameras for the first time in her superhero career. Towards the end of the Young Justice series, Cassandra became the leader of the team, after beating Robin during an election for command. Her secret identity was again publicly revealed when the second Silver Swan attacked her at her high school.
