The Battle Frontier, an area that originated in Pokémon Emerald makes a triumphant return in Pokémon HeartGold & SoulSilver. Situated to the north of Route 40, the Johto Battle Frontier is identical to the recently seen Sinnoh Battle Frontier

Firstly, there are several Pokémon that will not be eligble for entry within the Battle Frontier. They are as follows;

The Battle Factory makes a welcome re-appearance from Pokémon Emerald. Like its previous counterpart, it has you battling only with Pokémon that you rent out here. You start off with a team and go through the factory, battling other people with rental Pokémon. Once you defeat them, you have the opportunity to take one of their Pokémon in exchange for one of yours, allowing you to change your team for the better.

The battles are done in sets of 7, and as you continue your streak, the Pokémon you face will become better and your opponents stronger. For this, you really have to learn your type-matchups and the Pokémon's stat strengths and weaknesses

The Battle Tower also once again makes a re-appearance. It runs essentially exactly like the previous Battle Tower in Diamond & Pearl. It has three areas for you to go in; Single Battle, Double Battle & Multi-Battle. The battles are done in sets of 7 and as you progress through your streak, the Pokémon & opponents get stronger.

The Battle Castle is a battle facility that works similar to the Battle Tower. However, this time you do not have your Pokémon healed after battle. Instead, you earn Castle Points which can be spent on a variety of things including healing and seeing your opponent's Pokémon. The battles are done in sets of 7 and as you progress through your streak, the Pokémon & opponents get stronger.

The Battle Arcade in the south-east Corner of the Battle Frontier. It is a single or multi battle so 3 on 3 or 2 on 2. Before each battle, depending on what you spin on the wheel, you will get certain prizes that will aid you in completing your streak, or that will inflict afflictions on either yourself or your opponent

The Battle Hall in the north-west corner of the Battle Frontier is unique in that, as opposed to choosing a team of Pokémon to use, you can only use one or two if you're doing Double Battles. Once in, you get to select the type of the Pokémon you wish to face. The battles are done in sets of 7 and as you progress through your streak, the Pokémon & opponents get stronger.

Like in past games, battling in the Battle Frontier and the Battle Tower earns you Battle Points. These can be saved up and then spent on various items in the various stalls placed around the Battle Frontier. There is also an extra stall that will allow you to buy scratch cards in the hope of winning up to three items
