Carlos De Vil

Carlos De Vil is a major character in Descendants. He is the son of Cruella De Vil, and is portrayed by Cameron Boyce.

Background
Carlos is jumpy and anxious, but with the skills of a true tech prodigy. He’s been working feverishly on a project that would connect the Isle of the Lost to the outside world. Although he inherited his mother's love of fashion (especially if it's in black-and-white), he didn't inherit Cruella's love of dogs ― on the contrary, Carlos is deathly afraid of dogs (though it turns out this is because his mother told him dogs were rabid vicious animals that attack little boys who don't behave).

Instilled with an ever-present fear of dogs, Carlos joins the other villain kids as they take on prep school at Auradon to capture Fairy Godmother’s magic wand and set their parents free. His tech-savviness comes in handy when he and the other villain teens get stuck in a bind.

It is suggested that Cruella raised Carlos into thinking that dogs are killers, as well as vicious, rabid pack animals. As a result, this causes Carlos to have an extreme fear of canines, practically allowing them to chase him up a tree.

But Ben (the Prince, and son to Belle and the Beast), has him look after a dog to help Carlos overcome his misconception of canines, and grows to care about Dude, the school mutt.

Descendants: Isle of the Lost
In the book, Carlos is treated badly by his mother and sleeps in her dressing room on the floor, which is filled with bear traps. He is forced to look after and clean her furs, and it is also revealed that she loves her furs more than him, and refers to her car as "her baby." He has a treehouse, and a cat named Beelzebub, and recites the periodic table to himself when he is nervous.

On the Isle of the Lost, Carlos is incredibly smart and enjoys science and creating inventions, and refers to himself as a nerd. He also has an intellectual rival named Reza in science class and Jace and Harry, the sons of Jasper and Horace, as his "minions", though they are not truly his friends since Cruella forces them to hang out together. He gets beaten up and pushed around in school, and Mal bullies him into holding her party at his house, before they became friends. Evie was also the first real friend he ever had and helps her escape his mother's dressing room when she was trapped in there as part of Mal's prank. Carlos was also the one responsible for making a hole in the dome briefly when he was testing his invention, which would cause Maleficent's staff to gain its magic back as a result. After Mal and Jay force Evie to help them retrieve it, she also convinces Carlos to reluctantly join the quest. Though the group fail when the staff is unable to retain any magic, Carlos is finally accepted by Mal and Jay, beginning the four's friendship.

Descendants
In the film Descendants, it seems that Cruella forces Carlos to help touch up her roots, fluff up her fur, and scrape the bunions from her feet. This makes Carlos consider that heading to Auradon wouldn't be so bad, but Cruella uses his fear of canines as a way to control him. While in the limo headed to Auradon, Carlos takes a liking to chocolate. When they first meet Doug, he seems to have trouble remembering the names of the Seven Dwarfs, though Carlos seems to know the names of each and reminds Doug of Sneezy. Carlos is the most tech savvy of the group, as he seems to take a liking to video games and is able to use a computer to locate the museum where the Fairy Godmother's wand is. When Jay causes the alarm to sound, Carlos hears the phone and picks it up. He manages to disable the alarm and make them think it was a system error.

The Fairy Godmother assigns Carlos and Jay to sports. While Carlos doesn't seem to do well, Ben offers to help Carlos with this. As he practices sprinting, Carlos gets chased by the campus mutt, Dude. Seeing that Dude isn't vicious, Carlos starts to take a liking to canines, and takes Dude everywhere he goes in the film. During the big game between Sherwood, Jay insists that Carlos play with him, and with his help, the team wins the game.

When Cruella sees Dude and calls him an "earmuff," Carlos defends Dude; this is most likely the first time that Carlos has stood up to his mother. He then "burns" her by telling her to "give it a rest" with talking to a toy dog head. In one plan, it is Carlos' job to get into the limo and find the remote that activates the barrier around the Isle of the Lost. At the coronation, when Mal makes a speech on choosing to be good, Carlos is cautious at first, as he is nervous of the anger of their parents. But after being assured, he chooses to be good too. He is last seen dancing with Jane and Jay during the coronation party.

Descendants: Wicked World
Carlos is set to return in the animated short series Descendants: Wicked World and will be voiced by Cameron Boyce, who also portrayed him in the live-action film.

He appears in "Careful What You Wish For", appearing in Mal's tent after Mal accidentally rubs a lamp that causes her, Evie, Audrey and Ben to be sent to the Isle of the Lost. He claims that Jay has just given him a phone, but is curious where everyone is before taking a selfie of himself.

 * He is younger than his friends.
 * Evie was his first real friend.
 * He had a sidekick cat named Beelzebub (one of Lucifer's kittens). It was a gift in his baddie bag at Evie's 6th birthday party, and shows him affection his mother doesn't. Given there's no reference in the the film, this is likely a continuity error, or the cat had simply be adopted by someone else due to Cruella.
 * He is extremely smart, as he managed to temporarily break through the barrier.

 * Cruella forced him sleep on a lumpy mattress in her dressing room, which is accessible through her fur coat closet. There's another door, which Carlos use to bypass the bear traps security system.
 * He considers Harry and Jace (sons of Horace and Jasper), his "fake" friends (henchmen).
 * He re-purposes the various things in the basement (mostly dog stuff from her failed plan) for his science experiments, despite his mother's hysterical reactions to losing momentos of her past.
 * He is treated far worse than Mal, Evie, and Jay.
 * While on the island, Carlos's mother used him as a slave, forcing him to do several things, even the humiliating act of doing her laundry because she was too lazy to do it herself.
 * Likely because of this, he will usually hum the catchy tune of Roger's infamous song about her just for the joy of seeing her go into hysterics because of how much she hates said song.
 * He attended Dragon Hall (an evil school), before Auradon Prep
 * Evie's thinks of Carlos as her little brother, saying 'it would be tolerable to have a little brother like Carlos' whilst watching him work.
 * The only colors that Carlos can be seen wearing (red, black and white) are also his mothers signature color's. Evie's first thought about what it made her think of was a bloody skunk.
 * Evie gave Carlos his first pillow.
 * In Disney Descendants Yearbook, his "secret wish" is to run a rescue shelter for abused and abandoned animals(and children), while his "not-so-secret wish" is to never see a fur coat or a bunion ever again.

 * His favorite class is "History of Woodsmen and Pirates". Stating that there are very few dogs in those subjects(and not too many parents either).
 * He likes to see D'Artagnan's sword, hat, and boots at the museum. Stating that D'Atragnan was one brave guy and that he really looks up to him.

 * In the book it states that seeing Jay happy made him feel very happy.
 * As said by Cameron Boyce in an interview, he is more "I'm evil, don't hurt me!" and unlike the others does not actually do anything remotely mean-spirited throughout the whole movie and film, except helping with the plan, and perhaps kicking the apples in the first song. despite this, he is the last to choose good, but this is because of his fear of what their parents may do.
