Ultra Beasts

The Ultra Beasts are a classification for a collection of Legendary Pokémon that come from another dimension, and the Aether Foundation want to use one Ultra Beast, Cosmog, to create wormholes to harness the power of Ultra Beasts. Through the game, you will encounter and capture these mysterious Pokémon and when you encounter them, they start with a stat boost due to energy from the Ultra Wormhole.

First Encounter: #793 Nihilego

Location: Aether Foundation

The first Ultra Beast Encounter is with the mysterious UB-01 when you first are in the Aether Foundation. Due to the jamming signal the Aether Foundation has set up, this Pokémon cannot be captured and is at Level 27. Its Defense is boosted.

After this encounter, you then see UB-01 again when Lusamine forces Cosmog to create an Ultra Wormhole. This causes Ultra Wormholes to open up across the Alola Region, notably seen with Buzzwole/Pheromosa appearing and facing off against Tapu Koko. After that, you'll see a group of Nihilego in Ultra Space, where one temporarily merges with Lusamine.

Hunting Ultra Beasts

International Police

After defeating the league and becoming the first Alola Region champion, you will receive an Enigmatic Card from a mysterious man outside your house requesting to go to the motel in Route 8. Follow the instructions and you will meet Looker and his boss, Anabel. They will request your help to hunt down the Ultra Beasts, as many have managed to get through to the Alola Region and are causing havoc.

First, Anabel will challenge you to a battle. After defeating her, she will suggest going to the Aether Foundation to speak with Wicke. Wicke will give you the prototypes of special Beast Balls. These special PokéBalls have a high capture chance when used on the Ultra Beasts, but have a very low capture rate when not used on Ultra Beasts.

UB-05 Gluttony | #799 Guzzlord

Location: Seafolk Village - Resolution Cave

After capturing Kartana/Celesteela, then when you return to report on the situation, Looker explains how 10 years ago he and Nanu were working on an operation where they were hunting down Ultra Beasts, using a "Faller" as bait for the Ultra Beasts, since they have Ultra Wormhole energy, and that Anabel is a Faller, having arrived in Alola having lost her memory after seemingly being pulled through an Ultra Wormhole. They state that you are also a Faller due to your travel to Ultra Space. They then say the final Ultra Beast has been seen on Poni Island, and that they should go to the Seafolk Village. When there, Nanu challenges you to a battle once more to make sure you are ready. He then states it can be found in Resolution Cave. It can be found in the basement

Return to the restaurant and Looker & Anabel will congratulate you on a job well done and suggest reporting to Wicke about having contained all the Ultra Beasts.

When you go there, Looker bursts in and informs you of a mysterious black creatured zzipping across the sky of Alola. He insists it's an Ultra Beast but Anabel says there's no word of more Ultra Beasts. They say about how it must be Looker being tired. Anabel leaves to meet Nanu and Looker goes to the motel on Melemele Island.

The mysterious Pokémon turns out to be the Legendary Pokémon Necrozma
