"WOW! Can you do that Dad?!"[src]
Jimmy lived with his parents at 548 Primrose Lane, where he enjoyed watching a cop show called T.J. Lazer. Following the death of Jimmy's father at the hands of Clarence Boddicker and his gang, he and his mother moved away. Unbeknownst to them, Alex's remains were used in the construction of cyborg police officer RoboCop.
Later, while walking around his old house, RoboCop had a flashback of Jimmy watching T.J. Lazer on TV. He turned to his Dad and said, "Wow. Can you do that Dad?" RoboCop then found a picture of Alex, Ellen, and Jimmy in the kitchen, triggering a flashback to Halloween, where he set up the camera to take the picture, in which Jimmy was dressed as a devil.
Move from Primrose LaneEdit
RoboCop began stalking the Murphys after they moved away. One day while parked outside their new house, RoboCop saw his wife checking the mail as Jimmy pulled up on the lawn on his bike and walked inside with his mother, who could see the cyborg watching them. Shortly after this incident, Ellen took legal action against OCP, but believed there was a rationale for RoboCop's behavior. She was shown an unmasked RoboCop, whom she believed was Alex. However, RoboCop, having been repeatedly lectured to stop stalking the Murphys, was told he could never resume his relationship as a husband and father. When she attempted to reconnect with her husband, RoboCop simply said he was not Alex Murphy, his face covering was molded in Murphy's likeness to honor his memory. Mrs. Murphy left the meeting, depressed and confused.
