an image of a majestic humanoid robot with demonic features, combining elements from a mecha warrior and a demon. The figure should have the mechanical armor and weaponry of a futuristic robot, with a sleek, aerodynamic design in black, and red accents. It also has large, feathered wings similar to those of an demon wing, radiating a red glow. The robot stands in a powerful and ethereal pose, surrounded by a demonic background with soft light and clouds. The scene should feel both powerful and serene, blending technology and spirituality."
