Background
John Rainbird is an assassin for the Department of Scientific Intelligence in Longmont, Virginia.
During the events of Firestarter (1984) played by George C. Scott
Captain Hollister asks how Rainbird's trip to Venice went and Dr. Joseph Wanless walks into the room. Dr. Wanless tells Hollister he wants Andrew McGee and Charlie McGee killed due to the threat they pose. He explains how Lot 6 works and worries how strong her powers will be when Charlie hits puberty. Hollister suggests doing more experiments and Dr. Wanless threatens to expose The Shop. Later, during the night, Rainbird assassinates Dr. Wanless. Hollister tells Rainbird Andrew and Charlie were spotted in Tennesee. Rainbird then tells Hollister he wants to personally kill Charlie. As a Mailman is driving, he is hailed by Rainbird and Bates. The Mailman gets out to help Rainbird, who then strangles the Mailman to death and steals the mail. Rainbird tracks down Andrew and Charlie and uses a tranquilizer rifle to shoot them with tranquilizer darts, rendering them unconscious. Andrew and Charlie are brought to The Shop and Rainbird goes into Charlie's room posing as a janitor and tries to make friends with her. He eventually fools Charlie into being his friend by appealing to her sense of empathy when the power goes out due to a storm and he tells her he is afraid of the dark from his experience from being a POW in Vietnam. Rainbird takes Charlie riding after giving her a horse named Necromancer. Dr. Pynchot wants to do more tests on Charlie, but Hollister and Rainbird think they have tested her enough. Charlie tells Rainbird that she and Andrew are escaping. Agent Hunt walks in and tells Charlie he will be taking her to the stables. Rainbird goes to the stables and hides in the loft with a revolver. Hunt brings Charlie to the stables and then Charlie orders Hunt to leave. Rainbird calls to Charlie, but before he can grab her, Andrew and Hollister walk into the barn and Charlie runs to Andrew and they hug. Charlie tells Andrew that Rainbird is there and Andrew tells her the truth about Rainbird. Andrew tells Hollister to kill Rainbird and Rainbird shoots Hollister in the head. Andrew uses his powers to make Rainbird jump and Rainbird shoots Andrew in the neck. Rainbird shoots at Charlie and she melts the bullet and makes him combust.
