In the story mode of Cars: Mater-National Championship, Judd first appears in the cutscene for the first Rustbucket Race, adoringly watching Emma as she practices at the Rustbucket Stadium. Judd also makes subsequent appearances as an opponent in the third and fourth Rustbucket Races, where he usually places fourth.
Judd also appears in the arcade mode, as an opponent that can be randomly selected in Rustbucket Races.
Judd also appears in the book World of Cars, in the story Hoodwinked. In the story, Judd, Buford, Cletus, and Mater are bullied by Bubba, who throws Mater's hood into a tree. When Mater challenged Bubba to a backwards race, which Bubba lost, Judd did the countdown for them. Judd also had a subsequent diecast release in the Story Tellers Collection, at a production sale of about 4,000.
In Cars: The Video Game, Lewis, Judd, and Buford all share the same directory as Tommy Joe, but are set up as separate paint jobs, similarly to the Piston Cup racers. However, in all later games, they are set up as different characters, all with unique voices.
Judd has the most different eye colors of any character in the Cars franchise, they are green in Cars: The Video Game, blue on his artwork and in Cars: Mater-National Championship, and are the same shade of gold as his body on his diecast.
Judd has various tire colors, they are white like Zeke's in Cars: Mater-National Championship, but are dark grey like Lewis' in Cars: The Video Game and on his diecast.
Judd is the only one of the six known cousins of Mater who does not appear in the intro of Cars: Mater-National Championship, as the take from Rustbucket Race 1's cutscene was the moment when Judd was hiding behind the cousins, thus making him not appear.
In the PlayStation 3 version of Cars: Mater-National Championship, Judd has a slightly different window net, with a portion of it having been torn off.
