Marcus Thompson, or "Balthazar" in his transformed state, is a powerful and imposing figure. Strong and muscular, he stands at an impressive height, radiating an aura of power and authority. His human form is still marked by a hint of the fiery energy that fuels his transformation, with intense blue eyes that can shift to a glowing red when his dormant power is unleashed. He exudes a sense of calm and control, yet there is a simmering intensity beneath the surface, hinting at the monstrous force that lies within.
