Crimson is a tall imp demon with white hair, black and white striped horns, and yellow sclera. His skin is a dark shade of red, and he stands with plantigrade legs, his twisted tail bearing white accents. The right marking around his eye is larger than the left, and a single fang protrudes. As a vicious crime boss, he commands an army of shark-demon gangsters, cultivating an aura of fear in all who know him. His history of horrific abuse toward his son Moxxie and his wife reveals a man who places greed and power above all else, capable of killing his own blood without remorse. Yet, he can present a jovial, warm facade when it suits his purposes.
