Rennie Wickham is a character in Friday the 13th Part VIII: Jason Takes Manhattan, played by Jensen Daggett, and Amber Pawlick as a child. When she was young, Rennie was pushed into Crystal Lake by her uncle, in an attempt to make her swim, and nearly dies when a young Jason Voorhees attempts to drag her underwater. During the events of the film, Rennie is traveling to New York on the cruise ship Lazarus when Jason climbs on to it when it passes through Crystal Lake. As Jason begins killing everyone aboard, Rennie, her dog and a handful of others manage to flee from him and reach Manhattan after Jason sinks the ship. Tracking Rennie and her boyfriend Sean Robertson down after killing the other survivors from the ship, Jason chases them through New York and into the city sewer system. It is there that Rennie and Sean defeat Jason, flinging toxic waste at his face and climbing back to the surface as the sewer floods, sweeping Jason, who seemingly regresses back to a child, although this could be Rennie's perception. Safe from Jason, Rennie and Sean reunite with Rennie's pet dog Toby in the middle of Times Square.
In Freddy vs. Jason vs. Ash: The Nightmare Warriors, the non-canon, comic miniseries Rennie appears under the care of Doctor Maggie Burroughs and Doctor Neil Gordon, being one of the first recruited to their group of those who have survived both Jason Voorhees and Freddy Krueger. Rennie's power is described by Maggie as "empathy", powerful enough to alter her perception (explaining the visions she had of Jason throughout Jason Takes Manhattan). After Jason attacks the group when it first assembles Rennie and the others head to the capitol building in search of Director Gordon Russell, who Maggie claims is her father and the head of "Project Black Book". Along with Neil and the director Rennie is killed by Maggie, revealed to be Freddy's daughter Kathryn, after she reunites with her father.
