Where to Find Mewtwo in FireRed LeafGreen: Nintendo Switch

If you’re playing the Nintendo Switch version of Pokémon FireRed & LeafGreen and wondering how to get Mewtwo, the good news is that Mewtwo is obtainable in normal gameplay — but only after you beat the main story. You cannot catch Mewtwo early. It is strictly a post-game Legendary in FireRed and LeafGreen.

Mewtwo is located in Cerulean Cave, which only unlocks after specific requirements are met.

Cerulean Cave is a high-level dungeon filled with powerful wild Pokémon (often in the 50s and 60s). Bring plenty of Ultra Balls, healing items, and ideally a Pokémon with Sleep or Paralysis.

At the deepest level of Cerulean Cave, you’ll encounter Mewtwo at Level 70.

Save your game before initiating the battle. Mewtwo does not respawn if defeated, and there is only one available per save file.
