Giratina

Giratina is one of the types of Pokémon species. The species first appeared in the fourth generation of games, Pokémon Diamond and Pokémon Pearl. It is one of the many Legendary Pokémon introduced in Generation Four. It seems to be named after either the Guillotine or the girasol, a type of Opal. In the Nintendo DS video game Pokémon Platinum, Giratina is the mascot.

Description
Giratina is a large centipede-like Pokémon with short legs. It also has wings that it may use to use Fly. Certain characteristics of it resemple those of it's fellow Legendaries, Palkia and Dialga, including it's crown shaped footprints, it's unique eyes and its status as being named after a type of gem.

Giratina is found in Turnback Cave, a maze like cave. To catch Giratina, you must pass three pillars before passing through thirty rooms.

Giratana is a Dragon-Ghost type Pokémon, the first Legendary to be Ghost type. As a Ghost type, it learns Dark, Ghost and Electric type moves. Despite being a Dragon type, it doesn't learn any Fire, save Willl-'O-Wisp, or Ice type moves naturally. It can, however, learn the Draco Meteor move available only to Dragon types. It is the only Pokémon to learn the move Shadow Force, a move that allows the user to disappear and reappear to cause damage to the opponent.

Alternate Forms
Giratina has a secondary form that will be showcased in the Pokémon movie Giratina and the Sky Banquet: Shaymin. This form resembles a centipede more so than his regular form. As it has yet to be shown in games, it's abilities are still unknown. The Origin Form will be available in the upcoming Pokémon Platinum, which features Giratina as it's mascot.

Obtaining in Platinum
Normally in Diamond and Pearl you will find him in the Turnback Cave, but in Pokémon Platinum, Giratina is found in the Torn World after the Spear Pillar event. Cynthia will ask you if you want to go in the Portal to Torn World and you go in. In the Torn World you will find a Mesprit, Uxie, and an Azelf. When you find them using Strength nearby them you will see them fly somewhere. Follow the direction of where they fly. Be sure you get the HMs Strength and Surf which is required in order to get through the Torn World. Once you get to the bottom of Torn World you will battle Cyrus and after you are done battling him you will find the Giratina in its Origin Form which is stronger than the Another Form.
