The Distortion World is a location in Pokémon Platinum, and the true home of the legendary Pokémon Giratina.
The Distortion World is first accessed when the player reaches the summit of Mt. Coronet, Spear Pillar, to stop Team Galactic's plot to control Dialga and Palkia. After Cyrus enters the world, the player must follow him, and with the help of the lake trio, navigate the area.
More of the 3D capabilities of the Nintendo DS are utilized in the Distortion World than elsewhere in Sinnoh, with the strange physics of the world altered to a point where the player is able to walk on floors and Surf on water that is at right angles with the norm.
When in the Distortion World, Giratina will be in its true form, the Origin Forme. The Platinum Orb, found here, can be used to make Giratina assume this form outside of the Distortion World, where it would normally be in its Altered Forme.
During the player's first trip to the Distortion World in Platinum, Mesprit, Azelf and Uxie will guide them around, even helping them in the Strength puzzle.
The Distortion World is said to be another universe or world parallel to the Pokémon world. Two known gateways to it exist: one at the top of Mt. Coronet on Spear Pillar, and another in Turnback Cave.
It is a dark place with floor-like sections floating at many different angles. The world disobeys the normal laws of physics, allowing the player to walk and surf on walls in any direction. The only Pokémon known to inhabit the Distortion World is Giratina.
