Abbacchio is a tall man of slim build. On his head is a serrated headpiece that acts as a headband. He keeps long, light hair, dividing into spikes that angle outwards or upwards at their ends, being shoulder-length in his first appearance and growing longer until halfway down his torso. He wears a long, dark, lapel-less overcoat with laces that cross his bare chest, dark bell-bottomed pants, and black shoes. The buckle of his belt bears a silver/gold insignia of the letter "A".
