Mercenary and weapons specialist hired by the Kirbys. Upon being questioned by Billy, he claimed he knew the Kirbys “through church.” Shortly after their arrival on Sorna, Cooper was badly injured by the Spinosaurus. He tried, without success, to flag down the plane as it took off. Cooper was then killed when the Spino burst from the jungle next to him, snatching him up and eating him. Cooper was played by John Diehl.
