Mystek is a fictional character in the DC Comics universe. Created by Christopher Priest and Manny Clark in the Ray (vol. 2) #12 (May 1995) and died in Justice League Task Force #32 (February 1996). Fictional character biography Very little information has been revealed about Mystek's life, prior to her first confrontation with the Ray. Seong was a young Korean woman, born in Queens, New York, who preferred to be called 'Barclay'. Her father was involved with some sort of sensitive work, and was captured (possibly by some form of government agency), leading to her fear of federal agents. At some point, she had an ally named 'Tank', who was later killed. During an undisclosed incident in Seoul, she developed intense claustrophobia. She had an enemy named 'War Locke', whom she killed in a place called 'Empire Valley'. Lastly, her costume was sculpted to resemble a male physique, in order to further hide her true identity.

Some time later, after seeing through his trickery, Mystek again pursued the Ray. She journeyed to his apartment, where she stumbled across his electron shield, a device which allowed access to the headquarters of the Justice League Task Force, of which Ray was a member. Seong was transported before the assembled JLTF, and, believing that they were a government agency abducting her for experimentation, she attacked. She blasted her way out of their headquarters and escaped. Justice League Task Force Weeks later, J'onn J'onzz, the Martian Manhunter and leader of the JLTF, entered her store while in his human guise. Seong immediately determined his true identity, and flew outside to confront him. After a brief battle, J'onn explained to her that he had perceived her prior panic and recklessness as signs that she needed assistance, and, seeing some potential within her, offered her membership to his team.
