Body horror, or biological horror, is a subgenre of horror fiction that intentionally showcases grotesque or a visceral experience of the human body or of another creature. These violations may manifest through aberrant sex, mutations, mutilation, zombification, gratuitous violence, disease, or unnatural movements of the body. Body horror was a description originally applied to an emerging subgenre of North American horror films, but has roots in early Gothic literature and has expanded to include other media.
