Battle Tree

The Battle Tree (Japanese: バトルツリー Battle Tree) is a facility located on Poni Island in Alola. It can be accessed through Poni Gauntlet after becoming. It is the equivalent to the Battle Maison from Generation VI, the Battle Subway from Generation V, and the Battle Towers from other previous generations. It is led by and.

Challenges
At the Battle Tree, challengers compete to see how many Trainers they can defeat in a row. Losing one battle will reset the challenger's win streak to zero. Each time a challenger defeats a Trainer, Battle Points, or BP, will be awarded. The longer the win streak, the more BP will be received.

There are three formats a challenger can choose between: Single Battle, Double Battle, or Multi Battle. The challenger needs three Pokémon for Single Battles, four for Double Battles, and for Multi Battles, two per Trainer. Lastly, challengers cannot use more than one of the same Pokémon or item. However, this does not restrict Multi Battle partners from using the same Pokémon or item across teams.

There are two courses for each format: Normal Course and Super Course. A Normal Course challenge consists of 20 battles, the last of which will be against a. Upon successfully completing a Normal Course, the Super Course for the respective format will be unlocked, in which the challenger may rebattle the same on the 50th battle. Unlike the Normal Course, the Super Course is indefinite and ends only when the challenger loses a battle.

All NPC Trainers in the Battle Tree use Pokémon from a list of 996 Pokémon and moveset combinations. Each of their Pokémon has a fixed Nature and spread for effort values. s are equal across all stats and based on the Trainer using it. The gender and Ability are randomly selected each battle. Each Trainer will use two to four Pokémon, depending on the format selected.

In Pokémon Ultra Sun and Ultra Moon, the level and special Pokémon restrictions are lifted for the Normal Courses, while the opponents' Pokémon are still fixed at Lv. 50.

Special Pokémon
The following Pokémon species and their forms are banned from challenges that ban special Pokémon. Eggs cannot be used in any battle.

Battle Points
Like in the Battle Maison, the undefined receives Battle Points (BP) at the end of every victorious match. The number of Battle Points (BP) awarded after a match varies with the length of the current win streak, as shown in the table below.

Battle Legends

Special Trainers
In Super Battles, special Trainers appear every ten battles. Like with the other Battle Tree Trainers, their teams are randomly selected from a group of Pokémon specifically preset for each of them.

Multi Battle partners
In the Multi Battle and Super Multi Battle challenges, the player can choose to partner with a friend or with the AI. Unlike the Battle Maison from previous generations, there is only one default AI partner, Rada. To increase the number of AI partners available, the player must Scout opponents after defeating them in Single or Double Battles. Scouting a Trainer costs 10, and this will add the Trainer to the list of potential AI partners. When a Trainer is scouted, the first two Pokémon of their team will be the Pokémon they use in Multi Battles, and they are sent out to battle in the same order as well. If a Trainer who has already been recruited is scouted again, then the new team will override the old one. Battle Legends cannot be scouted, but the other special Trainers can be recruited.

In only, the player can also recruit Lillie as a partner for Multi Battles by speaking to her at Professor Kukui's laboratory at  after finishing Episode RR. She uses a Fairy-based support set.





IV judge
Next to the PC, the player can find a male, who is supposed to judge the s of the player's lead Pokémon. However, unlike the judges in the previous games, he's unwilling to judge the player's Pokémon. If the player has hatched at least 21 s, the judge will update the player's PC with a feature that allows them to view the IVs of their Pokémon themselves, after which he leaves.

Exchange Service Corner
