Rare grass and Surfing encounters inherit the first native slot's level range. Supplemental fishing follows each rod's native slots. These ranges exclude Lure effects and randomizer replacements; eligibility restrictions still apply.
Data source: configured Grand Anthology Gen 1–9 species, forms and abilities. The website uses frame-cropped copies of the game's existing Pokémon sprites, which remain franchise/artist-owned assets. Some alternate forms use labeled default-form artwork when their individual sprite is unavailable. See acknowledgments for credits.
