Scissorman

"Scissorman" (シザーマン Shizāman) refers to the identities of many antagonists of the Clock Tower series. There are multiple Scissormen and even Scissorwomen in the series.

They are terrifying, and sometimes invincible and invulnerable, serial killers who pursue the main character.

According to the Japanese novelization of Clock Tower, the Scissorman was regarded as the "Son of the Great Father" in the demonic cult followed by Theodore Barrows, an ancestor of the Barrows Family. They would be born into the family every few generations for the sole purpose of sacrificing children to "The Great Father".
