How to Find and Catch Legendary Pokémon

Locating Legendaries by Biome

Legendary Pokémon in Geno Mons spawn in specific environments tied to their nature. Groudon and Kyogre appear in land and ocean biomes respectively, embodying their elemental domains. Chi-Yu hides deep within Nether lava lakes, so bring fire resistance potions and explore lava seas at lower Y-levels. Tapu Koko guards island territories, so search tropical or island biomes. Darkrai and Cresselia emerge in specific conditions—watch for them during night cycles or in darker biomes. Hoopa spawns within desert temple ruins, so explore generated structures in desert biomes.

Preparation and Capture

Bring a variety of Poké Balls, as legendaries have low catch rates. Ultra Balls and specialty balls work better than standard Poké Balls. Weaken legendaries first using status moves like paralysis or sleep—avoid fainting them. Stock healing items and revives in case your team takes heavy damage. Necrozma spawns from deep space locations, so explore caverns and high-altitude areas. Iron Valiant and Iron Thorns appear as metallic variants in their respective biomes. Save before engaging any legendary to avoid losing progress if the encounter goes poorly.
