Frontier Brain Rules
Facility: Rental Pokemon only; swap after wins; Noland uses randomly generated rental-style Pokemon, not a fixed static team.
Symbol: Knowledge Symbol. Silver challenge appears when the stored streak plus the facility offset reaches 21; in practical play this is after 20 wins/rooms/events in facilities with offset 1 and after 21 in facilities with offset 0. Gold appears at source value 42.
Level mode: Level 50 uses Lv. 50. Open Level uses the highest level in the player's selected party, with a minimum of Lv. 60, from GetFrontierEnemyMonLevel().
Noland does not have a fixed static team. FillFactoryBrainParty() repeatedly rolls three legal rental-style Pokemon from GetFactoryMonId(), rejects Unown, rejects duplicate species, rejects duplicate held items, rejects current rental duplicates, and uses the Factory IV table. The Steven-looking data inside sFrontierBrainsMons is not the party you face.
Past rental count improves the opening draft: fewer than 15 rentals gives no boosted slots, then the rank increases at 15, 22, 29, 36, and 43 rentals.

Source Notes
- Source of truth: pret/pokeemerald
wild_encounters.json, mapmap.jsonobject/background events, mapscripts.inc,trainers.h, andtrainer_parties.h. - Encounter odds are aggregated by species and method from Emerald slot rates. Most rows are marked Any time because Emerald has no normal day/night wild encounter split.
- Pokemon table sprites use locally cached Emerald front sprites from
/guides/pokemon-emerald-pokemon-sprites.json. - Frontier Brain streaks and teams come from
src/frontier_util.c; Factory rental behavior comes fromsrc/battle_factory.c; facility mon sets come fromsrc/data/battle_frontier/battle_frontier_mons.h. - Trainer art on this page uses the local Emerald trainer manifest and reused Hoenn character art where Emerald-specific artwork is not available.
