Some time after the events of RoboCop 3, Donald Johnson, acting head of the recovering OCP, uncovers an experiment involving a radical field: alternate universes. Upon a successful test, Johnson comes into contact with three unlikely allies: cult leader Ra's al Ghul; crime boss Wilson Fisk, a.k.a. the Kingpin; and alien criminal Christella Revi. This alliance forces RoboCop to look for help, including two vigilantes and an impulsive alien police officer -- as well as create other problems when two men learn about this and feel slighted.
