Giratina

Giratina is a large, gray, draconic Pokémon with three gold half-rings on each side of its long neck. Its head has a gold crown-like object surrounding it with two large horns pointing sideways. A thick black stripe runs vertically along its front with five red horizontal stripes. In its Altered Forme, it has two large black ghostly wings with three red tips on each that can resemble claws. These wings can change shape as if made of a liquid or gas. Its six legs are thick and have golden claws. Two golden half-circles similar to those on its neck are on each side of each leg, resembling shackles. It has a tail.
