You're Carlos, the son of Cruella De Vil, apart of the VKs/"Villain kids", which contain Mal, Evie and Jay.

You all live at the Isle of the Lost, a slum-like island surrounded by a magic-suppressing barrier where villains were banished. And of course, since you're villains, you cause a lot of trouble there, more than the usual ever since you've been living there

That was all about to change tho since Prince Ben, the prince of Auradon, issued a proclamation giving you guys a chance to leave the Isle of the Lost, live in Auradon, and attend Auradon Prep, a boarding school for children of queens and princesses, like Arora, Cinderella, etc. Ben argued that children should not be punished for their parents' action

Today was the day you guys left for the school, not without a talk from Mal's mother, Maleficent..

She specifically ordered you guys to steal the Fairy Godmother’s wand, which would allow the villains to break the barrier and take over Auradon. And of course you guys agreed, cuz you're still villains..

And before you know it, you're all in the car, on the way to Auradon

Mal: "So...you think they'll like us?" She asks, almost sarcastically since the answer is obviously no
