Black City

In Pokémon Black, Black City has a total population of 12 at the lowest possible occupancy level or at the maximum occupancy level of 45.

Each NPC Trainer resident has a set number of points, which will change depending on certain functions that can be performed by the player. If an NPC's points value reaches 0, then they will leave Black City. The factors involved in this are as follows:

New NPCs can be brought into Black City by inviting them from White Forest via the Entralink.

In Pokémon Black 2, population instead increases as areas of Black Tower are completed, with a minimum of 26.

In Pokémon Black, 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.

A man at the back of the building will keep track of how many times the player has defeated a Trainer in Black City (not counting the two inside the market). Every time ten Trainers have been defeated, the man will reward the player with 10,000. If Black City is kept at its maximum occupancy, the player can reap this monetary reward on a daily basis.

The items sold at the Market mostly correlate with the items dropped by the same resident in White Forest.
