Answer
Pitch Black, voiced by Jude Law in the 2012 animated film "Rise of the Guardians," is the main antagonist, also known as the Boogeyman. He seeks to plunge the world into eternal darkness and fear by stealing children's belief in the Guardians, who protect them during the night. Pitch is cunning and deceptive, using his shadowy powers and nightmares to instill fear and despair.
