| WONDER GIRL II [Cassie Sandsmark]|
A friend of Wonder Woman, who 'borrowed' various Amazonian artefacts to help her when she was in trouble. This act of valour so impressed Zeus, the father of the Greek gods, that he granted her powers of her own (to the horror of her mother, Helena Sandsmark), entrusting her training to Wonder Woman and Artemis. Wonder Girl is headstrong and quick-witted and soon became a valued member of the super-hero community, spending much time with fellow young heroes in Young Justice.
When that group disbanded, she joined the new Teen Titans to learn more about being a hero, and at around this time she also discovered that Zeus was her true father. The Teen Titans became her closest friends and she grew particularly close to Superboy, forming a romantic relationship with him that was cut brutally short by his death in the 'Infinite Crisis'. In the year that followed, her path took her away from the Teen Titans, who she felt had let her down, and got her involved with some very strange people. Recently, she has begun to work with the remaining Titans once more, having been brought back together with them when pursuing the Brotherhood of Evil.
