Jeff is a truck driver who first appeared in Inside Man.
Jeff has brown hair combed back, brown eyes and a white T-shirt. In Ultimate Alien, he wears a blue shirt and cyan jeans.
In Inside Man, he picks up Tyler when he sees him walking through the desert. He instantly realizes that the man is mad as he does not know anything about himself and has to look at his wallet to learn what his name is. Finally, because of Tyler's weird behavior, he stops the car and kicks Tyler out.
