What is an Ultra Wormhole in Pokémon GO?

Seeing Eggs above Gyms is pretty normal in Pokémon GO, but from time to time Ultra Wormholes appear in their place. These portals allow Ultra Beasts to enter the world of Pokémon GO.

Here is everything you need to know about Ultra Wormholes in Pokémon GO and the Ultra Beasts that they spawn.

An Ultra Wormhole in Pokémon GO is essentially the same as a Five-Star Egg that can appear above a Gym. But, instead of a standard Legendary Pokémon, they will always lead to an encounter with an Ultra Beast.

If you want to check if there are any Ultra Wormholes spawning nearby, you can check the Nearby menu. If you see a portal symbol, that tells you that a Wormhole is nearby.

Ultra Wormholes will only appear when there is an Ultra Beast in the current Raid Boss rotation. As of December 2024, Dusk Mane and Dawn Wings Necrozma is appearing in Raids on Saturday, December 14 from 2 p.m. until 5 p.m. local time as part of Necrozma Raid Day.

So far, Pokémon GO has ten Ultra Beasts that could spawn when you see a Wormhole nearby.

These Ultra Beasts are some of the most powerful Pokémon in the entire game. Nihilego for instance, is the best Non Mega Poison-type Pokémon in the game. Xurkitree the second best Electric-type behind only Shadow Raikou.

That means that if you do see an Ultra Wormhole on your Nearby page in Pokémon GO, it is well worth trying to tackle that raid and capture yourself a powerful Pokémon.

Capturing Ultra Beasts works the same as any other Legendary Raid. Once you defeat the Raid, you'll get a set number of Balls to throw to try and capture the Pokémon. Unless the Ultra Beast is Shiny, the catch won't be guaranteed.

Keep an eye out on your local Gyms in Pokémon GO, and head out wherever you see an Ultra Wormhole.
