He and Belle are the rulers of Auradon, a modern-day kingdom inhabited by various Disney characters, and the parents of a young prince named Ben.
At the beginning of the story, his son decides to allow the children of some of the worst villains (namely Maleficent, the Evil Queen, Jafar and Cruella De Vil) to be transferred from the Isle of the Lost to Auradon. King Beast is initially furious with the idea, but Ben convinces him that the sins of the parents should not be passed on to their children as well. He is dismayed when Ben introduces Mal, the daughter of Maleficent, as his new girlfriend to his parents, and even more so when a fight erupts that results in Chad Charming being put under a temporary sleeping spell.
On Ben's Coronation Day, the Beast passes his crown to his son and thereon his throne. He witnesses the return of Maleficent and also Mal and her friends' heroic deed by defeating her, resulting them all on Auradon's good graces.
Beast is shown to be very sarcastic, to the point of playfully insulting his wife that he only married her because his only other option was a teapot.
- A shapeshifting statue of him as beast to man is in front of the school to symbolize that anyone can change their future.
