Entering Ultra Space
If the player finds a naturally spawned Ultra Wormhole, they will be able to mount a flying Pokémon or build up to the portal and enter it. When the player enters the portal, they will automatically be teleported to the Ultra Space Dimension.
If a player instead finds any of the Pokémon Solgaleo, Lunala, Necrozma or Palkia they can then use the external move Spawn Portal which will create a portal in the sky from where it was activated. This portal can then be accessed the same way that a natural spawned portal can be entered, however, this process can be redone after the external move cooldown has finished.
Inside Ultra Space
The Ultra Space dimension is much different than the overworld and in some ways takes a likeness to The End. It is full of floating islands of many vanilla biomes, as well as new biomes unique to the dimension. While inside the dimension, the player will find that while they can mount their Pokémon and use elytra, activating either of these will send the player soaring high into the air. Instead, the player should look to travel by foot.
The dimension itself contains a slowly changing sky, and fog, that will change colors over time. This fog can impair the users ability to see far in the Ultra Space dimension, but can be reduced if the player were to equip Safety Goggles in their helmet slot.
While exploring Ultra Space, players can expect to find many other dimension features, as well as new ones. Players can find Nether Strongholds with chests, as well as End Cities and ships high above the world. The world generation also creates new biomes, Ultra Deep Sea, Ultra Forest, and Ultra Jungle. Ultra Deep Sea is full of obsidian tendrils and spheres that cover the land and also can contain diamond and lapis blocks on them.
Finally, Hidden Ability Pokémon, along with Shiny Pokémon have twice the chance to spawn in Ultra Space.
Currently, eight Ultra Beasts only are obtainable via Ultra Space. These eight include:
Leaving Ultra Space
There are three ways to exit Ultra Space. The first method involves finding another Ultra Wormhole that has a chance to spawn while the player explore Ultra Space. The second method involves having Solgaleo or Lunala and using the external move Spawn Portal to create an exit portal. Finally, a player can leave Ultra Space by jumping into the void below. This will not kill the player and will instead teleport them back to the overworld.
Whichever way the player decides to use to exit Ultra Space, no matter how far they had explored, they will be returned to the same area that they have entered Ultra Space from.
