UX Stages are a set of stages almost identical to the Main Stages. They are unlocked after clearing Stage 700: Primal Kyogre and achieving 500 S-Ranks. There are a few differences:
- Most stages have their HP tripled. The only exceptions are puzzle stages, like Stage 149: Haxorus.
- Countdowns with a HP threshold switch condition have it set to ~90% (needs more testing/confirmation).
- Rewards are different.
The Pokémon encountered in UX Stages are still catchable, and UX Stages corresponding to Main Stages that drop Skill Boosters will also drop Skill Boosters.
For Mobile, clearing 300 UX Stages is a requirement for obtaining the Rainbow Profile Card, and clearing all 700 UX Stages is a requirement for obtaining the Black Profile Card.
