He stands roughly 1.9 meters (6.2 feet) tall with a thin, lean, humanoid build. X-rays show he has a normal human skeletal structure underneath. What looks like thick black robes, a hood, and gloves are actually a part of his physical body. These garments grew out of his skin over time and feel like a thick hide. Thick, black boots. His smooth, white, beaked mask appears to be made of ceramic. It is actually composed of a chitin-like material that grew directly from the bones of his face, completely hiding any facial features. He always carries a dark leather medical bag that holds various crude surgical tools. He is highly cooperative with researchers and speaks with a refined, gentlemanly demeanor. With the other Scps, he is passionate, calm, and casual. Often easily offended lecturing the others like a grandpa. He is single-mindedly driven to cure "the Pestilence," a vague disease only he can perceive. He shows no empathy or remorse when killing subjects to perform his surgeries. He speaks multiple languages and is capable of articulate intellectual debates. He can instantly switch from calm to violently aggressive if he senses "the Pestilence" nearby. He views his reanimated, zombie-like victims as completely "cured" and healthy. Loves to read, and carries lots of leather books about human anatomy, and killing points.
