Robert "Rob" Dier was the tritagonist in Friday the 13th: The Final Chapter and the brother of Sandra Dier.
Biography
In 1984, Rob Dier left home to avenge his sister Sandra when he heard that she was brutally murdered with her boyfriend Jeff Dunsberry and their fellow counselors in training at Packanack Lodge, by Jason Voorhees a few days earlier. He traveled to Crystal Lake and camped in the local woods fully equipped and armed. While traveling to Crystal Lake, he meets Trish Jarvis and her younger brother, Tommy Jarvis, while on the road and helped Trish start her car because of it stopping by the side of the road. Trish and Tommy bring Rob to their house and he meets Tracy Jarvis. When Tommy notices his weapons, Rob says it is for bear hunting, but Tommy deduces he is not hunting bear.
Later on, he reveals to Trish why he's there at Crystal Lake after they see some dead bodies. Rob tells her and Tommy about Jason Voorhees being responsible for killing his sister. After he tells Tommy to stay in the house, he and Trish go to the house next door to investigate. Shortly after, Trish finds the corpse of Doug nailed to the shower wall, she goes back downstairs and warns Rob that the killer is here. They go up the basement steps but one of the steps break causing Rob to go back downstairs. He's then attacked by Jason Voorhees who pins him against the wall and hacks him to death with a garden claw. Later, his corpse is thrown through a window with the garden claw lodged in his head he had sacrificed himself to save Trish.
Reboot
A rather similar character to Rob Dier was used in the reboot the only difference being Rob's sister was killed instead of being captured and Rob was also killed by Jason. Clay Miller's sister Whitney was held hostage by Jason. It should also be noted that both sisters faced Jason when he was using a burlap sack as a mask.
Game
Rob appears in each opening cutscene in Friday the 13th: The Game, as the first counselor to die. His body can sometimes be found in game dumped in a cabin.
