The Devon Corporation is a business that was first introduced in Pokémon Sapphire and Ruby. They are the main target of Team Magma or Team Aqua at the beginning of the game. The player is challenged with the task of delivering the Devon Goods over to a representative, and in reward, the representative gives the player a Great Ball. He later gives you Devon Corporation's new ball, the Premier Ball. The President of Devon Corporation also talks to the player, and even tasks him/her with giving a letter to Steven. He gives you a PokéNav in favour. At first, the Devon building can only be accessed as much as the first floor, but after the player helps Devon Corporation out a few times, he/she is allowed to venture all around the building, and all staff become instantly friendly with him/her.
