Demonic Lord of Darkness with Horns and Wings

The design depicts a powerful demon with a dark, terrifying aura. His body is covered in sharp, looming armor and claws. The horns on his head are massive and curved, and his wings stretch out in readiness for flight. The focal point of the design is a red, luminous line running across his torso, emphasizing demonic energy and evil. His eyes glow an ominous red, and his facial expression is full of rage and aggression. The details of the tattoo are incredibly detailed, from the intricately sculpted muscles to the textures on his skin and wings.
