The Battle Frontier (Japanese: バトルフロンティア Battle Frontier) is a special post-Pokémon League area featured in Pokémon Interregional Champion. It is similar to the Battle Frontiers. Unlike the previous Battle Frontiers, this Battle Frontier is actually split in two separate locations. The Battle Arena, Battle Pike, Battle Tower, Battle Factory, Battle Dome, and the Battle Pyramid are scattered over the Kanto region, whereas the Battle Spire and Battle Hive are located on Mythic Island. The rules of the facilities on Mythic Island also differ from those of the Kanto facilities.
