The Ultralocke challenge is a popular Pokémon challenge that involves catching and battling Pokémon in a specific region with certain restrictions. Pokémon Ultra Sun and Moon are the games used for this challenge.
| Rule | Enforced Mechanic | | :--- | :--- | | | Fainted Pokémon are automatically moved to a "Graveyard" PC box. You cannot withdraw them. | | First Encounter | On a new route, the first Pokémon you see is the only one you can catch. If it flees or KO's itself, you get no mon for that route. | | Nicknames | The game forces a nickname screen that you cannot cancel. | | Level Caps | EXP gain stops at the next boss's level. For example: Hala’s Crabrawler is Lv. 15 → your team locks at Lv. 15. | | Dupes Clause | You may re-encounter if your first Pokémon is one you already own (including evolutions). | | Shiny Clause | (Optional in the mod menu) Shinies are exempt from the one-catch rule. | Pokemon Ultra Sun And Moon Ultralocke Download
