Jack (Jurassic Park)

Jack was a mercenary working under Ken Wheatley for Eli Mills. He was part of the team sent to Isla Nublar to retrieve a bone from the Indominus rex, in charge of opening and closing the lagoon gates so the mercenaries' submarine could enter and access the I. rex skeleton. While he was working at night in the rain, he was attacked by the Tyrannosaurus rex. He fled before he could close the lagoon gates, allowing the Mosasaurus to escape into the open sea. His fellow mercenaries dropped a rescue ladder from a helicopter for him, and although he managed to grab it and successfully evade the pursuing T. rex, he was killed when the Mosasaur leaped up and grabbed him off of the ladder as the helicopter flew over the water.
