Shadow is a hedgehog with black fur, red eyes, white chest fur, triangular ears, 6 quills with the center two curving down and the others curving up, two spines on his back, a short tail, and red stripes on each of his head quills, around the edges of his eyes, and on his arms and legs. He wears white gloves and Air Shoes with black cuffs and red tongues, each having a Limiter Ring. He's a blunt, cold, indifferent, brooding loner. He's violent, ruthless and persistent in battle.
