Cerulean Cave, sometimes referred to as the Unknown Dungeon, is a cave located in the northwest corner of Cerulean City in Kanto. The cave is home to a wide variety of high-level wild Pokémon. Only trainers who compete and win in the Pokémon League at Indigo Plateau may enter, due to the potency of the Pokémon in the cave. At the end of the cave lies Mewtwo, the only one of its species in the game. He cannot be captured unless a trainer has three high-level and fully evolved Psychic Pokémon.
