An Ultra Wormhole is a dangerous and unstable portal that connects the Pokémon World and Ultra Space.



Rarely, an Ultra Wormhole appears as a crack in the sky, and later forms a complete wormhole. Cosmog is able to open Ultra Wormholes when subjected to extreme stress but this can be very dangerous for a Cosmog, since it can either die or not be able to move for a long period of time. Its two final evolutions, Solgaleo and Lunala, can open Ultra Wormholes much more easily than Cosmog. It is unknown if a Cosmoem is also able to form Ultra Wormholes like the rest of its evolutionary family.

Necrozma is able to open Ultra Wormholes like Solgaleo and Lunala too. Its Dusk Mane and Dawn Wings Forms are able to open and manipulate several Ultra Wormholes without any difficulty.


Fallers are people who passed thought an Ultra Wormhole, and possess the residual energy of the wormhole in their bodies, which causes Ultra Beasts to attack these people thinking they are a back passage to their worlds, sometimes people who go through the Ultra Wormhole can have a strong amnesia and just remember of the most basic information of their lives like: where they are from, what their names and things like, examples of these people are Mohn and Anabel. Currently the Fallers that still have their memories intact besides the player are: Lillie (in Sun and Moon), Lusamine, and Guzma, it is not known if the uniform that the Ultra Recon Squad uses causes some interference in the consequences of going through an Ultra Wormhole.


Sun and Moon

When the player is leaving the Dimensional Research Lab, the crack in the sky is briefly formed in the sky and then disappears.

The first time that a fully formed Ultra Wormhole appears, it is at Aether Paradise, where a Nihilego comes out of it.

Lusamine forces Nebby to open several Ultra Wormhole during the events on the second visit at Aether Paradise:

  • One of them is opened in her room where Nihilego came out from it.
  • Another appears near on Mahalo Trail, where a Buzzwole/Pheromosa appears from it.
  • Several other Ultra Wormholes appear in Alola: at Hau'oli City, at Paniola Town, at Route 9, at Maile City and in Seafolk Village, but the Ultra Beasts that emerged through these wormholes are unknown.

After Nebby evolves into Solgaleo or Lunala, it opens an Ultra Wormhole at the Altar of the Sunne/Moone and takes Lillie and the player to Ultra Space.

After beating the game, the player character can go into an Ultra Wormhole to reach the reverse world, where the night turns into day, and the Altar and the Lake of the Legendary Pokémon inverts to their counterparts, the player character can find Cosmog in this dimension.

Ultra Sun and Ultra Moon

Ultra Wormholes are accessible when the game has been beaten. They can be accessed when going through an Ultra Wormhole at the Alter of the Sunne/Moone, it also can let the player to Ultra Megalopolis and the reverse world. A few types of Ultra Wormholes while traveling through Ultra Space:

Sword and Shield: The Crown Tundra

The Legendary Clue? has a photo attached to it, showing an Ultra Wormhole above the Max Lair and Necrozma traveling through it. The Ultra Beasts that show up in Dynamax Adventures after giving the Legendary Clue? to Peony is also heavily implied to come from the Ultra Wormholes.

An Ultra Wormhole in the anime.

In A Dream Encounter, Solgaleo and Lunala appeared from two Ultra Wormholes in the Altar of the Sunne in Ash's dream.

In A Masked Warning!, an Ultra Wormhole appeared in Gladion's flashback explaining how Lillie got her fear of touching Pokémon, Faba opened an Ultra Wormhole with a machine, Nihilego appeared from the hole and attacked Young Lillie.

In Faba's Revenge, after Faba captures Nebby, he used its Ultra Aura's power to open the Ultra Wormhole again, but Ash's Pikachu destroyed the box where Nebby was trapped and the Ultra Wormhole deformed, however, the residual energy of Nebby's evolution formed the Ultra Wormhole, Nihilego came out and fought with Ash's Pikachu, Gladion's Silvally and Lusamine's Clefable, but it easily defeats them. After Lusamine sacrifices herself to protect Lillie and Gladion, Nihilego takes her away in the Ultra Wormhole.

In Revealing the Stuff of Legend!, Nebby after evolving into Solgaleo, opens an Ultra Wormhole to go where Lusamine is after Ash activate its Z-Power and with the Solganium Z and its new Z-Power Ring, Nebby enters in the Ultra Wormhole with Ash, Gladion, Lillie, Mallow, Lana, Sophocles and Kiawe in its back and reach to Ultra Deep Sea in Rescuing the Unwilling!.

In 10,000,000 Reasons to Fight!, Nebby returned to the Altar of the Sunne with Ash, his friends and Lusamine in its back though the same Ultra Wormhole opened to arrive at Ultra Deep Sea, which remained open all this time.

In The Professors' New Adventure!, an Poipole was seen traveling though an Ultra Wormhole in end of the episode.

In A Mission of Ultra Urgency!, three Ultra Wormholes appeared during the episode, one appeared in the forest near the Pokémon School where Poipole came out from it, the second appeared in Melemele Meadow during the Alola Detective Laki TV Show recordings, where a Buzzwole came out from it, the third was open by Professor Burnet to send Buzzwole back to his homeworld.
