Jemm was but one of many aliens captured by the D.E.O. and kept in containment in the organization's underground facility in National City. Because of Jemm's acute mental abilities, he was kept inside of a specially designed glass cell, which contained neural disruptors to dampen his powers. An earthquake caused a brief power outage in National City, but before the D.E.O. generators could compensate, Jemm had escaped from his cell.
He stalked the corridors of the facility, using his powers to kill and/or take control of various D.E.O. agents. Agent Alex Danvers goaded Jemm into coming after her, and succeeded in luring him back to his containment room. Situated on an upper walkway, she tried to take him down with an assault rifle, but Jemm's alien physiology enabled him to shrug off the bullets with little effort. However, she did succeed in shooting the gemstone off of his forehead.
D.E.O. administrator Hank Henshaw, who was in reality the shape-shifting Martian J'onn J'onzz risked exposing his true identity to stop Jemm. Using enhanced speed and reflexes, he tackled the villain and beat him into submission.
