Role in the film
Jason is only seen in the Dream Master. After pulling in her friends Joey and Kincaid in her dreams, Kristen is worried about Freddy's presence, she then leans near an open tunnel, where Jason immediately jumps out and bites Kristen's hand. The next day at school Kristen shows Joey and Kincaid her injured arm, which Kincaid rebuttals saying "My dog is like me, drag him into your crazy dreams and he gets wild".
While Kincaid is playing in his room, the door slowly opens to a shadowy figure that resembles Freddy's head, immediately in shock he gets up, the camera then pans to show that it is Jason who just entered his room. Jason then gets up to snuggle next to Kincaid, who then falls asleep, Jason then begins to whimper and Kincaid wakes up into his nightmare.
Immediately getting out of the car trunk, Kincaid spots Jason digging near the center of the dirt field when he goes to see what Jason is doing, Jason turns around and barks at him in anger. Jason then proceeds to urinate fire which soon causes Freddy's resurrection. Then Jason, in Kincaid's nightmare, soon runs away.
After Kincaid get stabbed three times, slashed and gutted with four deep wounds across his belly by Freddy, who turned back to life in his nightmare. He even grabbed his deep cuts in his stomach and shows the courage to defeat Freddy at this time, but because of the wounds in his abdomen was too fatally, Kincaid finally falls under Freddy's hand with his famous last words: "I'll see you in hell..." to Freddy. In the real world, Jason is standing on Kincaid's bedside, sniffing the deceased Kincaid and whimpering.
- It is noted that Jason is one of the only animal characters from the series, also he's one of the few that Freddy did not attack. Showing that apparently, like Jason Voorhees, Freddy has no desire to kill animals. However, in his childhood Freddy was seen killing a class hamster, though that could have been considered Freddy "experimenting" with death.
- In the remake, a dog similar to Jason makes an appearance as the pet of Kris. Possibly influenced by Jason.
