Dennis is a character in Lake Placid: The Final Chapter. He is a scientist of sorts. He helps Sheriff Giove, Reba and Ryan Loflin capture a croc in Black Lake for experimentation. He takes a bribe from Jim Bickerman and he takes Bickerman and his team inside the fence at Black Lake to get croc eggs. Everyone is split up and all but Jim and Dennis are killed. Dennis loses several fingers and is bitten several times. He is found by Giove, Loflin and Reba. They try to get him to safety but run across the Marshfield Swim Team's bus. Crocs attack and pull Dennis under the bus and devour him.
