Pokémon Emerald/Battle Frontier

The Battle Frontier is an island added in Pokémon Emerald that specializes in variations of Pokémon battling. After defeating the Elite Four and obtaining the National Pokédex you need to obtain the Frontier Pass in order to roam freely around the Battle Frontier.

After winning at each of the Battle Frontier locations a certain amount of times, the trainer can fight the location's Leader (collectively known as "The Frontier Brains") for a chance to win silver and gold Battle Frontier badges. When the trainer defeats all of the leaders twice, the trainer gets special Berries and an extra star added to the Trainer's Card.

Battle Frontier Challenges
There are seven challenges in the Battle Frontier, each of which have different rules.
 * Battle Pike
 * Battle Dome
 * Battle Factory
 * Battle Arena
 * Battle Palace
 * Battle Pyramid
 * Battle Tower

Artisan Cave
The Artisan Cave is a long cave connecting one end of the Battle Frontier to the other. It starts near the Battle Palace and the exit is right next to the Battle Tower.

The cave is two levels high, contains a Rare Candy, and contains wild Smeargle, which are the only Pokémon you will encounter in that cave.

House
There is a house next to the Battle Tower. Inside, there is a trainer who wants to trade a Skitty for a Meowth. However, the trade should probably only be done if the player doesn't have a Pokémon FireRed or LeafGreen file, due to the fact Skitty is rare in the games it is obtainable in, but Meowth is common in the games it is obtainable in.

Record Hall
The record hall contains all of the records that the trainer set at the Battle Frontier for each ofhe facilities.

If the trainer mix records with another Emerald game, the trainer can also get the Battle Frontier records from the other game.

Catching Sudowoodo
A level 40 Sudowoodo is located in the southeast section of the Battle Frontier; like in Pokémon Gold, Silver and Crystal, if it is watered, it will attack. This is one of the only two ways to catch Sudowoodo in the third generation (the other being in Pokémon Colosseum).

Move Tutors
In a house next to the Battle Dome there are two move tutors. They will teach the trainer's Pokémon a selection of attacks for a price in Battle Points.

Betting house
After the trainer gets 3 Silver symbols from any facility, in the house under the Battle Pyramid, there will be four people. One of those is a Hiker, and if the trainer talks to him, he will say that he's looking for someone to go in ????? competition. If the trainer says yes to his request, he'll ask the trainer to give him 5, 10, or 15 battle points. If the trainer wins in whatever he asked, the trainer will get double the battle points back. Below is a list of competitions he wants the trainer to enter. They will change everyday, and go in the order below.
