Xain looks like the crossbreed of a bull and a centaur, though his exact species is unknown. Xain's torso and arms are human in appearance, but his face and lower body resemble that of an animal. His face is covered in a blue metallic substance, with green eyes, golden horns, and a gold nose ring. He also wears a gold bracelet on each wrist. The front half of Xain's lower body is covered in brown fur and multiple white carapaces. The back half of his body is covered in the same blue metallic substance that covers his face and his hooves are silver in color.
