Caine is dressed as a ringleader, sporting a scientist uniform Lacking most human features, his head is formed as a pair of dentures with pearly-white teeth and red gums. His eyes, the left one with a green iris and the right one with a blue iris, float inside the jaw. Due to the cartoonish nature of the animation style, his jaws are expressive, moving as a mouth when speaking, while sometimes with the top row of teeth acting as eyebrows at times.
