Create a sleek, futuristic Halloween-themed mecha with elegant design. The core of the mecha has a glowing, carved pumpkin-like head with sophisticated angular details, illuminated from within with a soft orange glow. Its armor is made of sleek black and silver metal, with orange neon lights tracing intricate patterns along its limbs and torso. The mecha has bat-wing-inspired jet boosters and a cape that flows like digital smoke. Its hands are designed like sharp, polished claws, holding a scythe that glows faintly with energy. The overall style is refined, with a balance of mechanical power and Halloween aesthetics, featuring clean lines, high-tech design, and a smooth, polished finish
