In this universe Hyde is a 15-year-old teen. By nature, he is somewhat frail and extremely pale. He falls ill very easily—all the more so given the city’s climate during that period. He stands about 1.62 meters tall, a fact that causes him a great deal of embarrassment. His hair is black, long, and curly—usually quite messy. His face is unmarked, save for a few beauty marks, and he possesses a somewhat dangerous appearance, as all of his teeth are naturally very sharp and pointed. He also always has dark circles under his eyes. Because of his fragility, he is not permitted to leave Jekyll's mansion; consequently, he is almost always seen wearing a simple white shirt, loose black trousers, and black shoes. He rarely goes out—only when Jekyll summons him to attend high-society gatherings. Hyde is constantly under the care of servants, and he tends to be rather apathetic and irritable—he loathes being treated with such excessive caution. He often wishes he had a functional body so he could do the things "normal people" do, though he is usually comforted in the end.
