Ultra Space Wilds

Ultra Space Wilds (Japanese: ウルトラスペースゼロ Ultra Space Zero) is the home of various Pokémon not native to Alola, accessible through warp holes in Ultra Warp Ride, located several thousand s from Alola. It only appears in.

Gameplay
Legendary Pokémon are more likely to appear the farther the player gets in Ultra Warp Ride and through either a Rarity 3/4 warp holes. The Legendary Pokémon that appears is distinguished by its cry and its silhouette before battling it. Legendary Pokémon have the chance of being Shiny Pokémon through soft reset.

Pokémon encountered through the Ultra Warp Ride (excluding Legendary Pokémon and Ultra Beasts) have a chance to be forced to be Shiny. The Shininess of these Pokémon is determined when the player arrives at the Ultra Space Wilds. The probability that a Pokémon encountered this way will be Shiny depends on the rarity of the wormhole and the distance traveled.

Note that 3-ring "blooming" wormholes will always contain Legendary Pokémon (which do not have increased odds of being Shiny), unless all Legendary Pokémon which could be encountered in that particular wormhole have already been caught.

Any, or  that evolves into , , or  while the player is in the Ultra Space Wilds will evolve into their normal forms rather than their Alolan forms.

Only one Pokémon will appear per visit. If the Pokémon in question is a Legendary Pokémon, the screen will flash white and a message will be displayed on screen upon entry into that area within Ultra Space. Legendary Pokémon found here will respawn indefinitely until caught.

In addition, all Pokémon found here have a perfect 31 in at least 3 of their individual values.
