Finn was a tall and muscular young man of Ionia descent with olive skin, teal eyes, and straight black hair that was fashioned in an undercut that fell to his right side. His skin was extensively decorated with intricate black tattoos, most notably the word "kill" written in gothic calligraphy across his chest. He also had an ostentatious, gold-colored prosthetic jaw and was almost always seen wearing a bright yellow overcoat draped over his shoulders.
