You can ride Solgaleo or Lunala to explore Ultra Wormholes in Pokémon Ultra Sun and Ultra Moon

In Pokémon Ultra Sun and Pokémon Ultra Moon, you’ll be able to ride on the backs of the Legendary Pokémon Solgaleo and Lunala to travel through an Ultra Wormhole and reach the worlds that lie beyond. The Ultra Wormholes are strange pockets of space that have been seen in the Alola region before. In Pokémon Sun and Pokémon Moon, players saw a hint of the worlds that could lie beyond them, but most of the truth remained shrouded in mystery. In Pokémon Ultra Sun and Pokémon Ultra Moon, you can explore the various worlds that lie through these Ultra Wormholes. Within an Ultra Wormhole, there are countless warp holes that lead to different worlds. Try exploring different worlds by passing through these warp holes! You can even go to the home worlds of the mysterious Ultra Beasts!
