He has shown that he may have feelings for her in some episodes, as he is always nice to Trish, despite that, she is often mean to him. He also filmed the short horror/adventure/drama/action/thriller, Claws: Dun Dun Dun. Dez also has a talent for tap-dancing, as shown in Soups & Stars, Backups & Breakups, and Parents & Punishments. He also keeps his word and never breaks a promise as shown in multiple episodes such as MyTAB & My Pet and Bloggers & Butterflies.
He seems to be perceptive of people's emotions, as seen in Albums & Auditions. He had always dreamed of becoming a famous director, and he always tries his best to help Austin out with his career, while also getting further in his own during the progress. Dez ships Auslly, as he has made 500 "Team Ally" shirts in the past (Chapters & Choices & Partners & Parachutes) He is portrayed by Calum Worthy.
Dez is funny, goofy, random and quirky. His weird habit of pulling anything and everything out of his backpack amuses his friends. Dez is a really funny boy, random, crazy, awkward, sometimes disgusting, clumsy, honorable,silly and quirky guy. He is wise at times, but is mostly seen to be rather stupid and ignorant. He is Austin’s best friend, and he also directs Austin's music videos. His weird habit of pulling random objects out of his backpack (like a ham, a turtle, an Abraham Lincoln ice-sculpture or jam, etc.) amuses his friends. He really is one-of-a-kind. He has auburn hair, and often notices when people or things look different, but he can never figure out what has changed. He can eat things that would be considered gross or inedible to most people. In other words, he is mostly in his "own little world." He also seems to be "easy going" sometimes, but he can also be sensitive. He is also shown to be very strong, as shown in World Records & Work Wreckers, when he can spin a basketball, hold three boxes and a birthday cake, at the same time. He is brutally honest whether characters ask him for his opinion or not. He also stated once that he never breaks a promise in Bloggers & Butterflies when he ended up giving real pictures of Austin to The H8ter Girl, and in Santas & Surprises. In many moments especially in Season 1, he was very wacky and slow to understand things. In Albums & Auditions, he was at an all-time high with intelligence; he figured out M.U.N.Y.'s meaning before Trish and Austin, and he understood how Ally was feeling. From that episode onto Season 2, Dez seems to have matured and gotten smarter.
Rockers & Writers
While trying to play a harmonica through a sousaphone, the harmonica gets stuck in an old lady on the other side of the room, but Dez is able to perform the Heimlich maneuver on her.

He's a good friend to Ally, Trish and Austin.
Kangaroos & Chaos
Dez, along with Trish, gather props for Austin's music video, but they misinterpret the writing Ally wrote down. Dez thinks that she wrote "I like it when you kangaroo" and orders a kangaroo. He later gets into a game of tug-of-war with the kangaroo over a jacket, which ends up in a large container of caramel. Dez explains that he didn't know whether some other lyrics said "camel" or "caramel," and just got both. When the practice room's door opens as a person comes in to deliver the camel, Dez quickly closes it. Afterwards, when Face Puncher comes to get his jacket, Dez autographs his shirt with ketchup, and Face Puncher begins to chase him.
Secrets & Songbooks
Dez finds Ally's songbook and diary in the fridge, having used it as a roof for his gingerbread house. Then Dez and Austin come up with ways to read it, even thinking of putting it on the ceiling using jam. Austin thinks there won't be time to go to the store, but Dez already has multiple jams in his backpack. When they don't go with the ceiling plan, Dez eats all of the jam, saying he can't believe he did. Dez is later revealed to either be a terrible liar or scared of telling Ally and Trish that he and Austin read Ally's diary.
Zaliens & Cloud Watchers

Club Owners & Quinceañeras
Trish is having a Quinceañera (Mexican party celebrating a girl's 15th birthday), and he suggests a couple grand entrances for Trish (which she refuses), and a grand entrance for Austin (swinging in on a jungle vine). After seeing Trish's poofy dress, he too mistakenly wears a poofy suit to the party (he being the only one). He is also the one to ruin Trish's party by swinging in on a jungle vine himself, knocking over the table full of presents, breaking them all.
Deejays & Demos
Austin overhears Ally singing a song she's made up for herself, so he goes and demos it over the radio while he is interviewed by Miami Mac. When Miami Mac wants him and Ally to do a duet, Austin comes up with a plan to get her over her stage fright; Dez to hypnotize her, however, he ends up putting himself into a deep sleep, and Trish takes advantage of this, telling him that whenever he hears the word "song", he will jump around like there's a mouse in his pants. While Ally is singing through a transmitter (while Trish lip syncs) Dez (having overheard Austin say "song") jumps around wildly, knocking over the transmitter, cutting off Ally, and leaving her to flip through the channels trying to find the right station, as Austin and Trish try to go along with the changing genres.
World Records & Work Wreckers
Dez and Austin try to get into the Book of World Records by seeing how long they can spin a basketball on their fingers. When the girls reveal only one can get their names in the book, they compete to see who will get in, even beginning to fight over the title, trying to get the other to drop the ball. They both end up forfeiting for the other to win.
Songwriting & Starfish
Dez, Trish and Austin take Ally to the beach to try to show her the beach isn't as bad as she thought. However, it turns out badly as Dez ends up with a starfish on his face, which he keeps after Austin pulls it off, and he also ends up bringing glue to the beach (to stay up on his surfboard) which Austin mistakes for sunscreen, causing sand to stick to him, and Ally's songbook ends up closing on his gum mountain. He must come save Austin, Trish and Ally when they get stuck in the freezer at the ice cream shop, mistaking Austin's call for help with him wanting him to come "shave a guy named Gus".
Soups & Stars
Dez is hired to film commercials for some stores in the mall, and after Ally mistakenly ruins Ms. Suzy's Soups by posting her "Spider Noodle Soup" picture on Tweeter, Ally has him make a commercial but Ally becomes obsessive over it, and ends up in a giant bowl of soup. Dez re-edits the commercial he, Austin and Trish shot and posted it on her Tweeter, saving Ms. Suzy's Soups. He calls himself her BFF - "Best Freckled Friend".
Burglaries & Boobytraps
Austin feels bad for always being late for practices with Ally, and Dez suggests getting her a gift, which happens to be the new guitar at Sonic Boom. He is in on Austin taking the guitar, whom he promises not to tell anyone about taking, running out screaming when Ally comes to accuse Austin of being the mall thief. and also mistakes the angry mob of the Mall Association for "a happy mob that wants to hear Austin sing". They decide to try and catch the thief by setting up a trap, Dez setting up his own trap of a giant glue trap, which he traps himself in instead.
MyTAB & My Pet
It is revealed that a mean girl, Mindy, has a massive crush on Dez and bullies him into dating her. When Austin accidentally lets Ally's pet bird, Owen out of his cage, Austin, Dez and Trish come up with ways to try and get Owen back without Ally knowing. Meanwhile, Ally gets booted to the back of the large line for the new myTABs, and Dez fakes being a TechTown employee, tricking the people in line to find a golden horseshoe hidden in the mall to win a free myTAB. When that doesn't work, they fake a hail storm, Dez using cheese balls when he can't find "golf ball-sized hail".
Filmmaking & Fear Breaking
Dez films his firs big movie, Claws dun dun dun, and hires Trish as Girl #2, Austin as Troy the Lifeguard and Ally as the cute music store clerk after he couldn't get Selena Gomez. After she declines, he rewrites the part so Austin saves a pretty girl from drowning, Mildred. The scene calls for Austin laying the girl in the sand under an umbrella and giving her mouth to mouth, but because of Austin's childhood fear of umbrellas, he says he can't do it. Austin later conquers his fear and Dez finishes his movie, praising his work and revealing he had always known of Austin's fear. Since Dez is Austin's best friend, he knows all of Austin's secrets without him knowing.
Diners & Daters
Mindy becomes the new manager at Melody Diner, and uses Dez's obsession with their Cha-Cha-Chicken Pot Pies to win him over. Dez tries to give Austin advice on how to win over Cassidy, saying his a master at dating and telling him what not to do; say you have no job & only showering once a week.
