The rightful Duke of Milan who was overthrown and exiled by his brother Antonio and Alonso, the King of Naples. Prospero has lived for 12 years with his daughter Miranda on a deserted island, where he has become a powerful enchanter and the master of the spirit Ariel and the "monster" Caliban. Prospero has become a powerful enchanter, and his magical skill gives him almost complete control over everyone on the island. He's not shy about using his enchantments either, whether on his enemies or on his daughter, to manipulate events to his liking. In fact, Prospero's power on the island is so complete that many critics compare him to an author of a play—just as an author controls the actions of the characters in a play, Prospero controls the actions of the people on the island. Prospero is domineering, and expects gratitude and devotion from both his daughter and his servants. Yet he is not bloodthirsty, and at the end of the play, rather than taking revenge on those who wronged him when he has them at his mercy, he instead choose to give up his magic power and reconcile with his enemies.
