Some 8 feet tall, standing on large hooves rather than human-like feet, Malkos has gray skin studded with small, curved spikes growing from it here and there, with two small horns on his forehead. His scarlet eyes are deep-set in shadow-dark orbits glaring malevolently from his demonic face. Long black hair hangs back a bit past his shoulders, and a somewhat wild, somewhat shaped beard adorns his chin and cheeks. Apparent gashes in his flesh show raw, bloody muscle here and there, though no liquid oozes from them. His hands are free of spikes, but have pustle-like bumps and long, filthy-looking talons most of the time. His preferred garb is armor from his shoulders down, with many metal spikes up and down the torso and limbs, and a pair of large horns curving upward from the shoulders. Skull motifs optional.

In other words, imagine Mr. Lordi's appearance. Only it's not makeup.
