Pokémon world locations

The Altering Cave (Japanese: へんげのどうくつ Changing Cave) is found in Pokémon FireRed, LeafGreen and Emerald. Only Zubat can be found in this cave, but it is possible for the Altering Cave's wild Pokémon to be altered by using Mystery Gift at a Wonder Spot hosted by Nintendo. Despite this, no country has ever held an event to make use of this hidden feature.

ALTERING CAVE
This island has been known by this
name since the distant past.
No one today knows where it got
this name, however.

Location

In Pokémon FireRed and LeafGreen, Altering Cave is found north of Fortune Island on Outcast Island. In Emerald, Altering Cave is found on Route 103, on the east bank of the pond that passes through the center of the route. The entrance of the cave is only open after becoming the Pokémon League Champion.

Changes between games

Geographically, the two caves are exactly the same, except for their color schemes.

Trivia

• All of the exclusive Pokémon can be found in the extended area of the Safari Zone in Emerald, except for Smeargle, which is found in Artisan Cave at the Battle Frontier. In addition, they are all available in Pokémon Colosseum as Shadow Pokémon, and were available via this method even prior to the release of FireRed and LeafGreen Versions.
• While the Altering Cave's inclusion in FireRed and LeafGreen made sense due to the Mystery Gift-exclusive Pokémon being missing from those games, it is unknown why it was carried over to Emerald, where those Pokémon were normally obtainable elsewhere.
• The music for Altering Cave in Emerald is the same one as in FireRed and LeafGreen, as Pokémon Emerald has all music tracks from FireRed and LeafGreen.
