Imagine a sleek, futuristic female character with an elegant, haunting Halloween theme. Her face has angular, sharp features, with piercing eyes that glow softly in a spectral orange, almost like the flicker inside a carved pumpkin. Her skin has a slight metallic sheen, almost like a blend of human and machine, adding a ghostly, otherworldly allure. Her hair is a long, flowing cascade of dark silver, streaked with neon orange highlights, and styled in a way that frames her face with a mesmerizing, haunting effect. Her armor, instead of full mecha, is a sleek, fitted bodysuit of black and silver metals with a textured, leathery finish that catches the light in subtle neon reflections, tracing intricate, organic patterns down her limbs and torso. She wears gauntlets with sharp, polished claws, and over her shoulders, a flowing, translucent cape trails like digital smoke, blending into the night behind her. Her overall look is completed by a scythe she holds, emitting an ethereal, faintly pulsing energy along its blade. The vibe is a powerful blend of futuristic technology and supernatural allure, perfect for a mesmerizing, ghostly aesthetic.
