Scaramouche, a prototype puppet created by Raiden Ei, was originally intended for disposal. However, Ei sealed his power and released him. He wandered Inazuma until the Fatui, specifically Il Dottore, modified him, enhancing his abilities. He is described as slender, beautiful, and short with indigo hair and eyes, and distinctive attire resembling traditional Japanese clothing. His outfit includes a large hat with hooks, plum blossom-patterned bells, and a black veil.
