A Pokémon Center is a type of building that provides regulatory services for Pokémon Trainers. Pokémon Centers are found in most towns and cities of the Pokémon world; every major city or town holds a Pokémon Center. Some Pokémon Centers can be found outside of towns next to large forests or caves. Pokémon Centers are built where many Trainers gather and the area becomes popular. This is to accommodate those Trainers in need and serve as a resting spot. The most common service the Pokémon Center offers is healing Pokémon free of charge.
Pokémon Centers consist of a healing station run by a Pokémon Center Nurse, a trading connection club, a battling connection club (neither of which require wired connections as of FireRed and LeafGreen), and various NPCs that vary upon location (in rural areas, no NPCs may be present). As of Generation V, salesmen from the Poké Mart and the deliveryman (in Generation V) or delivery girl (in Generation VI) appear when the Mystery Gift function is activated, due to its integration with the Pokémon Center. Mr. Medal also appears here in Black 2 and White 2 when awarding the player any Medals. The connection clubs are absent in Generation VI and are replaced with the Player Search System.
Fly brings the player to the Pokémon Center in the town or city chosen, and Teleport brings the player to the Pokémon Center they last visited (or to the Pokémon Center of the city or town they are currently in). Also, if defeated in battle, the player will appear at the Pokémon Center most recently visited (unless the player has not visited a Pokémon Center, in which case the player will appear outside his or her home).
Pokémon Centers are important buildings and are found in most towns and cities, sometimes even on routes. Pokémon Centers are essential to Trainers as they provide many facilities and host most game mechanics. NPC Trainers and their own Pokémon are often found hanging around in Pokémon Centers, offering general advice and information on the events in the town or area it is situated in.
