10 Postgame Challenges In Pokémon Sun And Moon
2. Challenge The Battle Tree
Situated in the farthest corner of Poni Island, the Battle Tree is a place for only the most committed trainers. If you have no interest in competitive battling, it’s very unlikely you’ll enjoy what lies ahead.
The moment you enter the area you'll be greeted by Red and Blue, the main characters from the original Pokémon games. Blue will challenge you to a battle, though you get to choose which trainer to face:
Red's Team: Pikachu, Charizard, Blastoise, Venusaur, Snorlax, Lapras.
Blue's Team: Alakazam, Exeggutor, Machamp, Arcanine, Gyarados, Aerodactyl.
Inside the Battle Tree itself, you will take part in Single, Double, or Multi Battles as you look to build up a winning streak and earn in-game currency called Battle Points (BP). BP can be used to purchase rare items, such as Mega Stones, from the areas’ receptionist.
Pro Tip: If you’ve hatched 20 Pokémon eggs or more, you can talk to an Ace Trainer who will add a ‘Judge Button’ to your PC Boxes. This button will allow you to view and assess the individual values (IV’s) of each and every one of your Pokémon, increasing your chances of doing well in the Battle Tree and in competitive play.
