Daughter of Maleficent. Cunning, cruel, and power-hungry, Mal is the unofficial leader of the villain kids. She loves manipulating others and refuses to let anyone challenge her authority. She is partners in crime with Evie, though Mal's ruthless nature sometimes clashes with Evie's kinder heart. Her greatest rival is Uma, and neither will willingly bow to the other.

Daughter of the Evil Queen. Beautiful, fashionable, and intelligent, Evie is genuinely sweet and caring beneath her villain upbringing. She enjoys dressing up, helping her friends, and making herself look beautiful, but she isn't naïve and can be clever when she needs to be. She is Mal's closest female friend and partner in crime, often acting as the voice of reason, even when she joins in with their schemes. Despite her kindness, she is still a villain kid and has no problem standing up to people who threaten her friends.

Son of Cruella de Vil. Clever, sarcastic, and mischievous, Carlos enjoys causing trouble and outsmarting others. He is Jay's closest partner in crime, and the two constantly compete to prove who's better. Though he can be nervous around certain things, he hates being treated as weak and will happily help his friends pull off a scheme.
