Palkia is a light-purple, theropod-like Pokémon with stripes and markings of a darker shade and gray underarms and waist. It has round purple-striped plates on its shoulder area, where two pink pearls lie encrusted with a gray rim encircling them and fins in their back. Palkia's arms have extended formations resembling gauntlets and a purple band around each wrist. Palkia has a long neck, a pointed white crest on the top of its head that extends to its wings, two strong horn-like tusks on the sides of its jaw, and a powerful tail. It has faint cracks along its legs and tail.
Palkia has the ability to warp space, though it was said to create alternate realities as well. Palkia can use the power of space to travel to either faraway places or other dimensions. The space it controls can become more stable with its own breath. Palkia lives in a spatial dimension, making its behavior nearly impossible to study. However, Palkia has been seen in violent conflicts with its counterpart Dialga. It is known to be very protective of its home as well. It has also been referred to as a deity in Sinnoh myths.
Main Pokémon games
Palkia is only obtainable in Pearl, in the same way that Dialga is only obtainable in Diamond. It is summoned by the defeated leader of Team Galactic, Cyrus, who hopes to have it create a new universe for him, at the Spear Pillar on top of Mt. Coronet. It is stopped by Uxie, Mesprit, and Azelf, which nullify its power, and the player now challenges it. Its special item is the Lustrous Orb which amplifies Palkia's Water- and Dragon-type attacks when held by it. In Platinum, it can be faced after getting the Lustrous Orb.
Palkia appeared in The Rise of Darkrai, where it fought with Dialga and Darkrai in a battle that nearly destroyed Alamos Town. It reappeared in a flashback in Giratina and the Sky Warrior. In Arceus and the Jewel of Life, Palkia was shown for the first time with both the other members of its trio. It joined forces with Dialga and Giratina to fight against Arceus. Palkia also appeared in Hoopa and the Clash of Ages.
Origin and inspiration
Palkia, along with Dialga, may be based on the Shinto legend of Izanami and Izanagi, who is said to have created one island with a spear, erected a pillar on it, and from there created the islands of Japan. Appearance-wise, Palkia is likely based after a European dragon combined with a pearl. Its appearance may also be derived from the Plateosaurus or other bipedal dinosaurs such as the Oviraptor. Its Water type is possibly inspired by its association with pearls, or the large space that oceans are known to span. Metaphorically, it could be a reference to the ever-changing forms of physical matter in the universe, with energy and matter flowing between states and changing forms. It could also refer to the Ancient Greek astronomy depicting Earth submerged in water.
