Here's how it works:
1. Challenge the Battle Frontier: You access the Battle Frontier after completing the main game in Platinum.
2. Choose your battles: There are seven different Battle Facilities within the Frontier, each with its own unique rules and challenges.
3. Battle the Brain: Each Facility has a Brain who is the final challenge. These Brains use powerful Pokémon and often have unique strategies, making them difficult opponents.
4. Win to advance: Defeating a Brain grants you a special prize and allows you to move on to the next Facility.
Tips for defeating Frontier Brains:
* Prepare your team: Make sure your Pokémon are properly trained and have the right moves and items for the specific challenges of each Facility.
* Use different strategies: Each Brain has a unique style, so you'll need to adapt your strategies accordingly. Some Brains might be weak to specific types, while others might have tricky team compositions or specific rules to exploit.
* Research and plan: Take the time to research the strategies of each Brain and the best Pokémon and moves to counter them.
* Utilize the "Save" feature: The Battle Frontier allows you to save before each battle, so you can try different strategies or rematch battles if you lose.
The Battle Frontier is a great way to test your skills as a trainer and challenge yourself with difficult battles. Good luck!
