Pokémon Centers (also called PokéCenter) are buildings that fully heal Pokémon. They are located in most towns across the Pokémon world. They are ran by Nurse Joy and helped out by Chansey. They allow access to PCs for storage of Items and Pokémon. As the games progress, the player get access to more including trading and battling others Pokémon. They are a general meeting place. When the player's Pokémon uses Fly or Teleport, it will be to the Pokémon Center if going to a city or town. There are some in odd locations like the one in the woods outside of Union Cave in Pokémon HeartGold and SoulSilver where the player talks to the Fisherman in who will give him/her an Old Rod.If you're Pokémon has the Pokerus status,Nurse Joy will tell you about it.
