Ghost Ruther is a monochrome version of Ruther with dark hair that is fluffy and silky, white eyes and black mouth. Ghost Ruther is dangerously obsessive and curious. He speaks in a broken variant of English, which replaces some letters with numbers. He and his two other ghost friends, Peach and Mikel came from a white void, consisting only them. He is able to bend his neck into impossible angles. He is usually calm and caring, but he can be violent sometimes.
