Isle of the Lost: Revenge of the Forgotten Child

You know the story of King Ben, son of Beast and Belle, making a royal proclamation to give the children of the villains who were banished to the Isle of the Lost a second chance, bringing over the kids of the four most infamous villains in the land. Mal, daughter of Maleficent, Evie, daughter of the Evil Queen, Jay, son of Jafar, and Carlos, son of Cruella de Vil. The story you don't know, is the one of the forgotten son of Maleficent. Urcent, son of Maleficent and Ursula's brother Urson, was left behind on the isle, and now seeing his estranged half sister become the Queen of Auradon and have everything he never had, yet again, he wants to show Mal and the other VK's he's not so easily forgotten. And with the barrier down and his cousin Uma giving him an invitation to Auradon, he has the opportunity to do just that. But will he let his thirst for revenge make him a new villain, or will he be able to learn a new path in life like the rest of the VK's?
