The Battle Tree still stands firmly at the far end of Poni Island. And now it is the only place where most Mega Stones are available!

Quick access:
The Battle Tree

In the Battle Tree, you face a Trainer on a platform for the chance to climb to the next one, and so on until you reach the top. Not just any Trainer can get in, though, since you must beat the Pokémon League before you can access it. The place is run by two legendary Trainers, namely Red and Blue from Kanto.
You can battle in Singles, Doubles and Multi, in two modes: normal and Super. The first ends after 20 battles and your victory over one of the legendary Trainers, and it unlocks the second. In Super mode, the battle streak ends when you lose, and you face a special Trainer every 10 battles. You can also take a break at any time between two battles.
Each match won at the Battle Tree earns at least 1 BP (and more as you progress), a currency that can be spent at the Tree, at the Battle Royal Dome on Akala Island and at the various surf spots.
This place follows very specific battle rules:
- Pokémon above Lv. 50 are lowered to that level for the duration of the battles;
- you cannot gain experience or EVs;
- Bag items cannot be used;
- unknown Pokémon you encounter are not registered in the Pokédex, but the effectiveness (or lack thereof) of their moves is still shown in battle;
- Pokémon are healed at the end of each battle, and lost items (for example after being hit by Knock Off) are returned to their owners.
However, many Legendary Pokémon are banned: Mewtwo, Mew, Lugia, Ho-Oh, Celebi, Kyogre, Groudon, Rayquaza, Jirachi, Deoxys, Dialga, Palkia, Giratina, Phione, Manaphy, Darkrai, Shaymin, Arceus, Victini, Reshiram, Zekrom, Kyurem, Keldeo, Meloetta, Genesect, Xerneas, Yveltal, Zygarde, Diancie, Hoopa, Volcanion, Cosmog, Cosmovum, Solgaleo, Lunala, Necrozma, Magearna and Marshadow.
The dear old Judge is still there, too. Talk to him after hatching 20 Pokémon to unlock the “Judge” function, attached to the PC, so you can evaluate your Pokémon’s IVs yourself.

Recruiting allies
For Multi Battles (doubles), you will need a partner’s help. You can connect locally with a friend, or rely on a Trainer controlled by the game. The Pokémon Breeder from Sun and Moon is still there (see her team below), but there is something new: now that Lillie has become a Trainer, she can also be chosen as a partner, provided you have talked to her beforehand in Professor Kukui’s lab!

See the details of Lillie’s team at the Battle Tree.
Every 10 solo battles, you will face a special opponent in the form of a well-known Trainer. If you manage to beat them, you can spend 10 BP to recruit them. Special Trainers recruited this way can then be used as partners in Double Battles. The two Pokémon they use are picked from a set of possible configurations for each of them. Note that since there are several variations of the same Pokémon, moves, Abilities and held items may vary.

Item exchange counters
Like any place of its kind, the Battle Tree has somewhere to exchange your BP for various items.
The counter on the right gives access, for 64 BP each, to practically all Mega Stones (except those given by Red). Indeed, unlike in Sun and Moon, Mega Stones are no longer offered through distributions or tournaments.
The two other counters offer held items with various uses.

Red and Blue

Two other legendary Trainers are also present at the Battle Tree. Red and Blue, on vacation in Alola, are the ones who welcome you when you arrive at the Battle Tree. Neither has changed much, other than being a few years older. They bring with them their solid reputation as Kanto’s Champions, even if Blue only held the title for a while, which opened the doors of this place to them.
To top it off, Blue (who speaks for both of them) suggests you take on one or the other.
If you choose Red, you will face the following team.
