Rojack (real name: Jack Morris), also sometimes misspelled "Rojak", is a high-ranking officer and dangerous member of the Black Dragon crime syndicate.
Rojack is also known to be the most clever of all his fellow clan member, but also known to be very manipulative and dangerous due to his career as one of the most wanted men in both the United States of America and Hong Kong.
He sought after the Kitai, a stone object of unknown origins, which is said to be a divine relic crafted by the gods, holds the power to create portals to traverse other dimensions. For Rojack and his Black Dragon thugs, it would mean a golden opportunity to open doors to untold riches beyond their wildest dreams. Rojack then holds both Jax and Mikka hostage until the Special Forces arrives and took down Rojack and his gang, at which point he is cast into a portal opened by the Kitai leading to Outworld. Rojack ends up trapped inside it and his fate may have been unpleasant.
It is unlikely that Rojack himself survived in the perilous realm of Outworld.
