UltraSpace is a separate dimension built around Ultra Beasts. Four biomes, an unfamiliar wild-spawn pool, and the only place where Ultra Beasts spawn in the open world. Catch rates here were reworked in May 2026 — landing an Ultra Beast or Paradox Pokémon is meant to feel earned.
Getting there
Open /warps (or talk to the Warp Master at spawn) → Special → UltraSpace. You drop within 1000 blocks of the dimension's centre. To leave, use /spawn or any warp.
The four biomes
UltraSpace has four biomes, each with its own terrain, palette, and spawn pool:
- Purple Forest —
ultraspace:purple_forest - Lava Canyon —
ultraspace:lava_canyon - Biomechanical Plains —
ultraspace:biomechanical_plains - Stormcrack Fields —
ultraspace:stormcrack_fields
Different Ultra Beasts spawn in different biomes, so it's worth visiting all four before you decide a target is unfindable.
Ultra Beasts
Ultra Beasts spawn primarily in UltraSpace. The full roster:
- Nihilego
- Buzzwole
- Pheromosa
- Xurkitree
- Celesteela
- Kartana
- Guzzlord
- Poipole
- Naganadel
- Stakataka
- Blacephalon
Beast Balls have the best catch rate on Ultra Beasts. See Ultra Beasts for the catching guide.
Tips
- Bring a strong team. The wild pool here trends high-level and hits hard.
- Stock Beast Balls before you arrive — they're not sold in UltraSpace.
- Catch rates were tightened in the May 2026 update; expect to throw more than you would for a comparable overworld legendary.
