Norman has the unique ability to see and communicate with ghosts. This gift isolates him from his peers, as they view him as strange and different. His ability is central to the plot, as it allows him to interact with the spirits of the dead, including the ghost of his deceased grandmother, who provides him guidance.

The main antagonist in ParaNorman is the vengeful spirit of a young girl named Agatha, who was wrongfully accused of witchcraft and executed by the townspeople. Her spirit seeks revenge on the descendants of those who wronged her, and Norman must confront her to save his town from her wrath.

Norman's family, particularly his parents and his older sister Courtney, play a significant role in highlighting Norman's struggles. His parents are often dismissive of his abilities, while Courtney is embarrassed by him. This family dynamic emphasizes Norman's feelings of isolation and the challenges he faces in being accepted for who he is.

Norman's friendship with Neil is pivotal to the story. Initially, Neil is one of the few who accepts Norman for his abilities, and their bond deepens as they face the supernatural challenges together. Neil's unwavering support helps Norman gain confidence, and their friendship becomes a source of strength as they confront the ghostly threats.

The town's history with witches is crucial to the plot, as it sets the stage for Agatha's curse. The townspeople's fear and misunderstanding of the past lead to the tragic events that unfold. Norman's journey involves uncovering this history, understanding the consequences of the townspeople's actions, and ultimately seeking to break the cycle of fear and vengeance.
