Create a Halloween-themed dragon character with a sleek and futuristic design. This character should embody classic dragon traits, featuring shimmering, metal-like scales resembling steel or chrome, large mechanical wings with an aerodynamic shape, and sharp horns and claws made of metallic material glowing with blue or green LED lights.
