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.
Background
Palkia was originally a Pokemon resident of Spacial Rift until recently, when the main character comes from the future and gets attacked by Darkrai. This caused a distortion in the space, and outraged Palkia, who drags the main character and his partner to Palkia's domain, Spacial Rift. There, he intends to destroy the two characters; however, the two manage to defeat Palkia, and soon learns that it was Darkrai who distorted everything. Later, the player can recruit Palkia at Spacial Rift.
As Palkia can control the space itself, Spacial Rift's exit is hidden, thus requiring the player to defeat Palkia at first. This can be confirmed by losing against Palkia before defeating Darkrai.
Although Palkia is referred to as a genderless species, it is referred to as a male in this story.
