Giratina is a OC by Bokurei

Altered
Giratina is a large gray draconic Pokémon with gold half rings circling the back of its neck. Its head has a gold crown-like object surrounding it with two large horns pointing sideways. A thick black stripe runs vertically along the front with red horizontal stripes. In its Altered Forme, it has two large black ghostly wings with red tips that can resemble claws. These wings can change shape as if it's a liquid or gas. Its six legs are thick and clawed. Though in a square

Origin
In its Origin Forme, it takes on a serpentine look, with six black ghostly streamers on its back with red spikes at the tips. Its legs are reduced to spikes, and four additional golden spikes appear near the edge of its tail. While in Origin Forme, the three gold half-rings can grip objects. The horns on its head are now facing the back, and the black vertical stripe is broken into pieces and runs all the way down its body. It can only be in its Origin Forme when in its home, the Reverse World, or when holding a Griseous Orb. Though in a square
