From Bulbapedia, the community-driven Pokémon encyclopedia.
Palkia (Japanese: パルキア Parukia) is a Pokémon that appears in Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness and Pokémon Mystery Dungeon: Explorers of Sky. It is located in the depths of Spacial Rift, and is the semi-final boss of the game's epilogue. Palkia, like Primal Dialga, is angry at the main characters, this time for distorting space without permission, which is later revealed to be distorted by Darkrai, the Pokemon that wrecked Temporal Tower.
Although normally genderless, this Palkia is referred to as a male.
Physiology
Palkia looks dinosaur-like, similar to Dialga, though it seems to be based on a theropod, the bipedal carnivorous dinosaurs. Palkia’s body is mainly a shade of light purple, although it has stripes and markings of a darker shade and a grayish-colored arm underside 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 somewhat gauntlet-like extended formations and a purple band of coloration at the 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.
