One of the series' main cast members, Jude is an easy-going teenager with a knack for extreme sports. A free spirit, Jude's over-the-top comportment and childish pranks serve as the program's comic relief.
Jude and his best friend Jonesy Garcia participate regularly in pranks and other acts of mischief, a fact that has placed them on the mall's Most Wanted list, and by "Snow Job," banned Jude from the mall entirely. Unlike Jonesey, however, Jude is prone to more eccentric behaviors. Some of these behaviors include naked skydiving, proposing that all currency be replaced with the barter system that uses food from stick-it, taking a tropical vacation in the mall fountain, and donating seventeen pints of blood just for the sake of free stickers and doughnuts (each time adopting a new persona, since he was only allowed to give blood once). He has never bathed much in his life. As a result, his friends have become used to the "faint lingering aroma" that always hangs around him.
Jude's knowledge of romantic relationships was initially very limited. In "The Five Finger Discount," he expressed an attraction toward a talking leather armchair named "Betty," and was utterly devastated when Jonesy sold the piece of furniture. The event did, however, lead to his meeting with Starr, who would be his most prominent girlfriend over the course of the series. The two shared many interests, but their love ended when Starr went goth in "Lights Out". He started to show feelings for his friend Caitlin Cooke. He subsequently formed a long-distance relationship over payphone with an Australian girl named Callie, and was involved briefly with an overly clingy girl, Rita, who he paid Jonesy to dump in his place. In addition, Jude acted as Jen Masterson's fake boyfriend during her infatuation with fellow employee Charlie Dobbs. More recently, he has dated Melinda Wilson (Rachel Wilson).
On several occasions, Jude and Jonesy have been jokingly depicted as a gay couple. In "Unhappy Anniversary," parodying the film Ghost, Jude sits closely behind Jonesy while making pottery, and they engage in their first onscreen kiss in "The Khaki Girl". Jude furthermore shows little discomfort when he cross-dresses to get in touch with his feminine side.
Jude is employed in the Galleria Shopping Mall at Underground Videos. While it remains to be seen whether or not the job will be permanent, he is also hired as a zamboni driver. He previously worked as the mall's official child babysitter, as well as the manager of Stick-It, a stand specializing in kebabs and other skewered foods, but was shut down by mall security after customers began complaining about his lack of cleanliness when preparing their meals (one found a cockroach in a kebab that he ordered). At the beginning of the series, Jude had intended to get a job at the North Shore Surf and Skate shop, but was refused due to a bad interview.
Jude once adopted a goldfish abandoned at Underground Videos. Carrying it around in a plastic bag wherever he went, he fed "Fish" soft drinks and cinnamon buns which inadvertently killed his new pet.
While speaking to people, Jude usually addresses them as "dude" or "bro" in reference to males, and "dudette" or "bra" in reference to females.
