Ultra Wormholes have been a part of the series since Pokemon Sun & Moon, serving as a portal to the mysterious realm of the Ultra Beasts.
There are already plenty of rare Pokemon in the series, but the Ultra Beasts are a different kind of beast altogether. While Legendaries and Mythicals have been around in Pokemon Go for a while now, Ultra Beasts began to appear in June 2022, with the first being Nihilego.
Since then, Pokemon Go has introduced more Ultra Beasts, including Buzzwole, Guzzlord, and Celesteela.
Ultra Beasts are just as powerful as Legendaries and could shake up the Go Battle League meta, so when you spot an Ultra Wormhole, you’ll want to know exactly how they work so you can catch one!

What are Ultra Wormholes in Pokemon Go?
Ultra Wormholes are portals that appear at Gyms in Pokemon Go and allow Ultra Beasts to travel into our world. They’re pretty much the same as Raid Eggs but will always lead to an Ultra Beast encounter.
You can find Ultra Wormholes by visiting the Nearby menu and looking out for the portal symbol. When the timer ends, whichever Ultra Beast is featured in the Raid Boss schedule will appear in its place.
In terms of their history in the franchise, Ultra Wormholes first appeared in Pokemon Sun & Moon on the Nintendo 3DS. Discovered by Professor Mohn, Ultra Wormholes allowed Ultra Beasts to travel from Ultra Space to the Alola region.
Which Ultra Beasts can appear in an Ultra Wormhole?
So far, there are eight Ultra Beasts in Pokemon Go:
- Nihilego
- Pheromosa
- Buzzwole
- Xurkitree
- Celesteela
- Kartana
- Guzzlord
- Poipole
Ultra Beasts only stick around for a limited time, so there won’t always be one to encounter.

How to catch an Ultra Beast in Pokemon Go
Once you’ve found an Ultra Wormhole and an Ultra Beast has emerged from it, it’s time to battle! Just like with Legendaries, you’ll need a strong team and multiple trainers to team up with if you want to win.
When you’ve defeated an Ultra Beast, you’ll be given a limited amount of Ultra Balls to throw. It’s never guaranteed that you’ll catch one, but you can use Excellent Curveballs and Silver Pinap Berries to help.
