In Pokémon Sun and Pokémon Moon, Ultra Wormholes were strange pockets of space that mysteriously appeared throughout the Alola region and were shrouded in mystery. In Pokémon Ultra Sun and Pokémon Ultra Moon, these Ultra Wormholes return and players can ride on the Legendary Pokémon Solgaleo and Lunala to travel through them to reach the various worlds that lie beyond. Players can visit many different worlds via these Ultra Wormholes – including Ultra Megalopolis. The world of Ultra Megalopolis is a place that has had its light stolen by Necrozma. Within this world, a mysterious tower-like building shines with brilliant light but whatever waits at the top of this structure is currently unknown.
