Cerulean Cave, known as the Unknown Dungeon in Generation I, is a cave located northwest of Cerulean City in Kanto. The cave is home to 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. The cave has existed in every Generation with the exception of Generation II, when the cave was sealed off.
Cerulean Cave has had many different layouts over time, getting a change from not only one Generation to the next, but also from one game release to the next. In Pokémon FireRed and LeafGreen, the layout is true to that of the original Red and Green games, aside from the addition of Rock Smash boulders.
Another addition in FireRed/LeafGreen lies in the fact that trainers are now required to further prove themselves before entering the cave, which is done by completing the quest on Sevii Islands and bringing the Network Machine to operate.
