This is a list composed of all of the main antagonists that appear in the Laika Universe.

Aggie Prenderghast Edit

Agatha "Aggie" Prenderghast is the main antagonist of Laika's 2nd full-length animated film ParaNorman. She is Norman Babcock's distant relative and closest friend. She is not really evil or cruel, but she does seek revenge on the town of Blithe Hollow, and the seven Puritans led by Judge Hopkins, who wrongfully sentenced her to death for the alleged crime of witchcraft.

She was voiced by Jodelle Ferland.

Agatha Prenderghast was an 11-year-old girl who lived with her mother in Blithe Hollow, Massachusetts. Similar to her distant relative Norman Babcock, Agatha had the ability to speak to the dead. Her abilities however caused fear among the superstitious townsfolk, who began to believe she was practising witchcraft. It was reasonable that during the old times, Blithe Hollow fear the strange, non-understandable, and difference of other beings, including at this age, the supernatural. A fact which made the Blithe Hollow citizens, except Aggie's mother, believed that how she can speak to the dead was due to a deal with the Devil she has made to gain powers. Eventually, Agatha was brought on trial and testified against six witnesses. The town judge, Hopkins, found Agatha guilty and sentenced her to execution. During the trial as what Aggie herself shows Norman as well as disturbing visions that Norman had in the middle of a rehearsal of his school play, it was implied that Agatha is also usually said to be playing in the woods, alone physically. Before she was hanged, Agatha threatened vengeance upon her accusers. It is unknown if her mother knew of her daughter being held in court, and what more unknown if her mother knew of Agatha's death, since she is buried in an unmarked grave under an old tree, where Aggie states, during her resolution as the tree where her mother used to tell her happy stories when she was alive.

After her execution, Agatha's ghost cursed her accusers to rise from the grave as the living dead so as to experience the same prejudice they had put her through. After death, her accusers felt remorse over their actions. Aggie's story was told over the generations, except with Aggie represented as an evil witch rather then an innocent victim. Eventually, the story became a tradition for the town.
