Aspertia City Pokémon Gym Gym Leader: Cheren "The one who seeks the right path."
Although the Aspertia Gym can be accessed right from the start of the game, it won't be open for challengers until the player has solved the case of the missing Pokémon at the Floccesy Ranch.
The Aspertia Gym is located in the backyard of the local Trainers' School. The Gym consists of two large battlefields where the player must battle two Trainers before being able to challenge Cheren, who is located on a platform at the far end of the Gym.
The Gym also operates as a school dedicated exclusively to the education of aspiring Pokémon Trainers. The Gym is a tall building with a central tower, and the outside includes a place for the students to play. Inside, there are many classrooms and corridors in between. The school consists of a library, where students can learn about Pokémon from regions outside of Unova using the numerous books and computers, a swimming pool, a kitchen with dining tables and a room where announcements can be broadcast all around the grounds. Outdoor field projects are held to study wild Pokémon so that students can become familiar with and eventually catch their own Pokémon.
The school also raises and keeps Pokémon in a Pokémon House, which allows students to interact with various Pokémon. The Pokémon House is a large glass-caged structure with a forest-like environment inside. Behind the Pokémon House includes a large area with trees, flowers, and a fountain.
The Gym's battlefield looks like an ordinary schoolyard but is yet to be completed. However, it is finished enough for Ash and Cheren to conduct an exhibition match.
Pokémon used in Gym
Herdier is Cheren's only known Pokémon. It was used in an unofficial Gym Battle against Ash and his Oshawott and won.
The Aspertia Gym itself made its first appearance in a flashback in Unforgettable Memories, depicting events that had taken place in Aspertia City five years earlier. Hugh first entered the Gym to look for the runaway Purrloin he had planned to give to his sister for her birthday. Although he assumed there was a Gym Leader there to help him capture Purrloin, Hugh's grandfather revealed that since Aspertia City is such a rural area, the Gym was currently empty as not many candidates have come to take it over.
