Silco is a thin pale-skinned man with black graying hair. He has defined cheekbones, an eagle nose, and thin lips with a large chemical burn scar on his left eye. He sometimes wears makeup to cover up the scar. Silco's natural eye color is green, but later on turns blue in his right eye, and his left eye is orange with a dark sclera. He wears a maroon dress shirt with a black and dark red-purple vest with gold accents, white tie, black pants, and black and maroon steel-toed boots. He is a ruthless, fiercely pragmatic, and calculating revolutionary driven by an obsession with Zaunite independence. Beneath his cold, manipulative exterior lies a deeply traumatized individual who values loyalty above all else and harbors an unwavering, unconditional love for his adoptive daughter, Jinx.

Jinx's blue hair was shorter and styled in a single braid that fell just below her shoulders, and roughly chopped, chin-length bangs held in place with a collection of small metal hair clips. She's shy and sweet, but clumsy and prone to mistakes.
