Cerulean Cave in FRLG

Cerulean Cave (Japanese: ハナダのどうくつ Hanada Cave), sometimes referred to as the Unknown Dungeon (Japanese: ななしのどうくつ Nameless Cave) in Generation I, 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.

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 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 and 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 restoring the Network Machine to operational status. Another change is in the fact that more Pokémon can be found only by fishing, while wild Pokémon found just by walking around in the cave are reduced in number. In Generation I, there are also several species that make no sense to be in the cave, such as Dodrio and Pokémon that are otherwise only obtainable by stone-induced evolution; however, this has been fixed in Generation III, at the cost of some of the wild Pokémon diversity.

In Generation II, Cerulean Cave completely collapsed. However, the leftovers of Mewtwo's presence can still be found in the lake near the cave, in the form of the item Berserk Gene.

In Pokémon HeartGold and SoulSilver, Cerulean Cave has not collapsed and Mewtwo can still be found inside, although, as in previous generations, a person stands in the way until the player has proven him or herself by defeating all eight Kanto Gym Leaders.

Layout

The layout of the cave has been tweaked several times in the past, particularly in Generation I; however, the most recent layout (depicted in FireRed and LeafGreen) looks almost exactly like the design in the Japanese versions of Red and Green, but with improved graphics.

Trivia

• In Generation I, any Pokémon that can only be found in the Cerulean Cave is listed as "area unknown" in the Pokédex. This was fixed in Generation III, however. Whether this was intended or just a glitch is unknown (most likely a glitch).
• Though its design varies with each iteration, the version of it found in Pokémon FireRed and LeafGreen and Pokémon HeartGold and SoulSilver is very heavily similar to the one in the original Pokémon Red and Green, which was never released outside of Japan. The only difference is the Generation III addition of Rock Smash boulders.
