Ultra Crater (Japanese: ウルトラバレーUltra Valley) is the home of Celesteela, accessible commonly through Rarity 3 warp holes and rarely through Rarity 2 warp holes in Ultra Warp Ride, located more than several thousand light-years from Alola. It only appears in Pokémon Ultra Moon.
The Ultra Crater is a large expansive world with several craters filled with a green substance. The land has what looks to be metal pipes growing as roots throughout the rock, most likely from the many Celesteela that have planted themselves there. A few red monoliths stick out of the ground as several geysers are also present shooting out steam. Several Celesteela are frequently present in the ground as the world is frequented by earthquakes due to Celesteela launching themselves out of the ground and into the sky. Large mountainous terrain is pictured in the background. The sky is actively yellow due to the geothermal activity from the geysers and the Celesteela.
Special encounters
Pokémon Ultra Moon
Celesteela can be encountered and caught here. One Celesteela will spawn per visit. Celesteela will appear as ??? and will not be registered as seen in the Pokédex until caught.
Celesteela absorb energy from the ground in this world, as hinted by their depiction in this world and their Ultra Sun Pokédex entry. They also glow and launch themselves into the sky, subsequently causing earthquakes, as shown in the first encounter with Celesteela in this world.
