The Black City market is only present if the player has a number of four Trainers or more in Black City. Items sold here vary according to the current residents of Black City. Bargain Pass Powers will not affect the prices of items sold here. Black City is a sprawling metropolis with many large buildings and skyscrapers. At low level occupancy, there are fewer buildings, which are smaller in size. When using the Entralink feature to visit another player's White Forest, the player can invite people that have left to come to Black City to increase occupancy; this can enable new items to be purchased and new varying Trainers to battle.
