Set in the aftermath of Descendants 3, when Audrey's defeat has led to further opening of the Isle of the Lost, Season 1 introduces Kylon Pridemore, 17, who has been raised on the Isle of the Lost by his grandparents Scar and Zira after his parents Kopa and Vitani were separated from him through a magical accident when he was an infant. He is part lion-shapeshifter (able to partially transform — glowing amber eyes, claws, enhanced speed — in the Descendants universe's magic-infused human world), part human in appearance, and entirely Isle-raised: sharp-tongued, street-smart, fiercely loyal to his small group, and carrying the enormous emotional weight of having been raised by two of the Disney villain world's most dramatically intense personalities. His closest friends are Claudine Frollo, 16 (daughter of Judge Claude Frollo) and Princess Joanna, 16 (daughter of Prince John of Sherwood). When Auradon Prep's new Isle inclusion program selects Kylon's group for enrollment, his journey to find his parents Kopa and Vitani — who have been living in Auradon's Pride Lands region since being separated from him — becomes the season's emotional engine, alongside the culture shock of Auradon, new friendships with the established VK group, and the revelation that someone is trying to re-seal the Isle barrier using ancient magic.
