To the far northwest of town a large stone and concrete, almost temple-like manor dwarfs the rest of Amatree Town in its shadow. While the rest of Amatree Town is constructed of simple transient wooden buildings, the Amatree Town Gym is built to stand the ravages of the forest and time. The gym leader, Tiko, specializes in Fire-type Pokémon.
A small wooden building with a blue roof sits in the southwest corner of Amatree Town; this is Amatree's trading post, where supplies from other towns and even Pokémon are sold and traded. Having no use for the standard currency used throughout the rest of the Tandor Region, Amatree's citizens instead trade berries found growing on trees through Route 10. Considering how dangerous it is to venture through Route 10, it seems like a pretty fair trade.
There are three traders at the post during your visit: one with medicine and Poké Balls, another with rare items like evolution stones, and a third with Pokémon available for purchase.
Just west of the long path up to the gym, you'll find a wooden building with a red roof. Being so far removed from the rest of the Tandor Region, Amatree Town does not have a completely functioning Pokémon Center; without electricity, it's impossible for the town to provide PC or trading services. However, the house does have the only widescreen TV and PS3 in town. They'll be happy to heal your Pokémon for you, but here's hoping you brought the right Pokémon along to do the job.
After defeating Tiko, you will run into Theo after heading into Route 10. He finally beat Sheldon and is catching up to Amatree Town. After a battle, he will give you HM03 (Surf).
