Ultra Space is a term used in the Pokémon universe, specifically in the games Pokémon Sun and Pokémon Moon. It refers to a mysterious dimension that exists outside of the regular Pokémon world. In Ultra Space, players can encounter unique Pokémon and explore different environments that are not found in the main game. In Ultra Space, players can access various areas known as Ultra Wormholes. These wormholes serve as portals that lead to different locations, each with its own challenges and rewards. The dimension is home to powerful Ultra Beasts, which are special Pokémon that have unique abilities and characteristics, making Ultra Space an exciting place for trainers to explore.
