Pyroraptor was cloned by Biosyn and released to live within their sanctuary, where at least one individual lived atop the frozen lake held behind the valley's dam. After Owen Grady and Kayla Watts crashed landed into the lake, they encountered the Pyroraptor as they attempted to move towards the dam. The Pyroraptor slowly moved towards the pair, but as the ice cracked further beneath their weight it used a hole within the ice to dive underwater, circling them at first and pursuing them when they ran. During the pursuit, Owen fell through a hole in the ice, but before the Pyroraptor could reach him Kayla managed to pull him out. With that the Pyroraptor burst from the hole and attempted to run down Kayla and Owen, with all three climbing onto a walkway on the dam and racing towards an elevator. Owen and Kayla managed to get into the elevator and shut it on the Pyroraptor, who clawed at the door even after being tazed by Kayla and the elevator beginning its descent.
