Matthias is a tall, slender doll with a slightly stooped figure and sickly, pale skin. The left side of his body is horribly damaged as compared to his right. His dark brown locks are styled into neat waves on the right, straggly and frayed on the left, and combed down in neat spikes to reach his neck on the back. his left eye is nothing more than an empty cross-stitch of the same color. His mouth is pulled back by two rows of stitching on his upper and lower lip
