Caliban

Caliban is the monstrous slave of Prospero who is resentful of working for him.

Caliban was born as the only child of the exiled witch Sycorax, and as such grew up only knowing the island that the story takes place on. Eventually his mother died and later he was discovered by Prospero after his exile from Milan. In the play itself Caliban find Trinculo and Stephano and offers to make them the lords of the island if they kill his master, Prospero. Prospero finds out about the plan and confronts the trio in the final act of the play, causing Caliban to repent his actions.
