Battle Tower

The Battle Tower in Generation III is located in the Hoenn region, and is a post- Pokémon League battle facility located in Hoenn's southeastern sea, inaccessible except by boat, as it connects to no routes. Its purpose is to provide a challenge to all comers, with the best and brightest Trainers from all over flocking to it to see who is the strongest. Carrying over its functions from the Battle Tower in Pokémon Crystal into Ruby and Sapphire, the Battle Tower is expanded on in Pokémon Emerald where it becomes one of the seven facilities in the Hoenn Battle Frontier and allows for Double Battles as well as Multi Battles (with the player being able to partner up with a computer-controlled Trainer or a linked human-controlled one).
