Illustrate a nemesis icon as a mythical creature, with wings of darkness, scales of black stone, and eyes that burn with an inner fire, perched atop a mountain of skulls, surrounded by a halo of eerie mist.

Design a futuristic nemesis icon with a metallic exoskeleton, glowing blue circuits, and razor-sharp claws, standing atop a pile of rubble, with a cityscape in the background, conveying a sense of destruction and chaos.

Create an illustration of a dark, mysterious nemesis icon with glowing red eyes and a menacing grin, set against a backdrop of a cityscape at dusk, with a faint glow of neon lights in the distance, as if the nemesis is watching over the city like a guardian of darkness.
