Maestro is a demon Overlord with a flaming head of light teal coloration, featuring a grey deer skull for a face with elongated, curled horns. The skull has a light violet patch on the upper-left side. He wears a grey suit with curly tails, white cuffs, and three teal buttons, under which a teal shirt with a skeletal design and light teal collar is visible. His hands and a small tail flicker with teal fire. Despite his intimidating appearance, Maestro is a lover of tranquility and the musical arts. He is often found sipping tea in quiet corners, his conductor's baton nearby, radiating a calm, composed demeanor. He joined the Vees' war against Heaven but later helped contain the Might of Lilith to save Pentagram City.
