Sadako appears as a young woman whose face is hidden under her long black hair, & she wears a white dress that has water stains on it that is also frayed at the end also being 5'5 in height. Sadako can simply cause her victims to die of a heart attack by revealing her grotesquely malformed eye. Her sheer presence can alternatively drive people to commit suicide in brutal ways and cause people to drop dead on the spot, even without showing her eye.
