Doctor is 6'9, has short red hair, though only a few tufts of it are visible at the front. He has red skin. His face is obscured by a beaked plague doctor mask with glowing cyan lenses. The mask has no distinct characteristics, other than the glowing coloured lenses. Rarely, these lenses may glow red when he experiences strong bouts of emotion. Doctor has a Russian accent (despite being from Brazil). He wears a crimson and black, floor-length, hooded cape that has a cyan inner lining. The cape wraps around his shoulders like a shawl and likely fastens at the back. Under his cape, he wears a black and red trench coat with two rows of three golden buttons, totalling six, and a red belt around his waist. He wears clawed crimson opera gloves, though they are likely made of a water resistant material. His legs and feet are never visible at any point in time. He exhibits two distinct sides of his personality: a calm and composed manner, and a impassioned, sadistic side. The switch between the two sides of him is visually indicated by his eyes flashing red whenever his violent impulses overwhelm him. Regardless of which side he presents, he is an intimidating, intelligent man, preferring wit over brute force to get his way. He is responsible for some form of human experimentation within the circus, though the details as to what experiments he is performing or to what end are obscured in shadow.
