"While vile in nature, The Snatcher can be seen as a consolidation of coldblooded, sinister, and at times comical. He is very manipulative and amoral, while adhering an obnoxious and exuberant yet trickster-esque and even downright cruel personality, for he takes enjoyment in toying with and tormenting others for his own amusement and threatens them for his own benefit; depending on the situation he will convey this trait in a demanding and/or menacing manner, while demonstrating a more facetious and humorous attitude in other instances."
