History:

Originally nothing was known of the life of the girl know only as Secret before she became a ward of the D.E.O. (Department of Extranormal Operations). Here she was kept in an air tight room, so that the D.E.O. could observe her as her meta-human powers grew. As she grew older and more confident in her powers she discovered that she could leave her room in her gas form.  Leaving her cell at night she could travel the facility undetected, and she soon found out that there were dozens of other "subjects" like her, that, the D.E.O., were performing cruel, and torturous test on.   When the doctors discovered what she knew the decision was reached that she be terminated. Secret managed to escape the compound, and hide from her captors in a neighboring town. It didn't take long before the D.E.O., discovered her whereabouts, and set out to evacuate the town. This brought the attention of Robin, Superboy, and Impulse who decided to investigate. When the boys managed to capture Secret, she pleaded with them to let her go. Suspicious of the D.E.O.'s motives the boys decided to free her, and help in faking her death. Secret now roams the world enjoying her freedom, while the boys keep her existence, a secret.
    Teaming up with Wonder Girl and Arrowette, Secret and the girls joined the Young Justice team.  Battling villains such as a ghostly form of Desperro, Bedlam, and Young Justice's greatest threat Harm.  Recently more of the origins of Secret have been exposed.  After the villain known as Harm, returned from the dead he again threatened the team of Young Justice through Secret.  Reveling that Harm was her brother and that Secret's fear of water and electricity stem from her death.  As she was taking a bath and listening to the radio, Harm in his younger years needed a sacrifice and to do so, threw "Suzie's" radio into the bathtub electrocuting her, but also activating her meta gene.   Suzie was last seen in battle with Harm in the mountains saving her Young Justice teammates.
