Carlos DeVil . 

Carlos is jumpy and anxious, but with the skills of a true tech prodigy. He has been working feverishly on a project that would connect the Isle of the Lost to the outside world.

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.

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

But Ben, the son of Belle and the Beast, has him look after Dude, the school mutt, to help Carlos overcome his misconception of canines, and grows to care about Dude. He then found his love for Dogs but unlike his mother, he does not want to harm them.

Auradon: Set between D1 and D3. Carlos spends his days trying to fit in with the Auradon kids, but spends most of his time with his friends or Dude unless Jay drags him to practices.
