Giratina

Giratina (ギラティナ), is a Pokémon species in Nintendo and Game Freak's Pokémon franchise. Created by Ken Sugimori, Giratina first appeared in the video games Pokémon Diamond and Pearl, but gained prominence in the sister game, Pokémon Platinum, which it was made the mascot of. It later appeared in various merchandise, spinoff titles and animated and printed adaptations of the franchise. Giratina is featured prominently in the film Giratina and the Sky Warrior, and later appears in the film Arceus and the Jewel of Life.

Known as the Renegade Pokémon, Giratina is one of a trio of legendary Pokémon, alongside Dialga and Palkia, that represents Pokémon Platinum and appears on its cover art. While Dialga and Palkia represent time and space, Girantina represents antimatter. In Platinum, it was given a unique design called the Origin Forme, which depicts it as a floating creature that writers have described as being similar to a snake or larva. Since it appeared in the Pokémon series, Giratina has received generally positive reception. It has been featured in several forms of merchandise, including figurines, plush toys, and the Pokémon Trading Card Game.
