Icirrus City

Main article: Pokémon Fan Club

The Unova region's Pokémon Fan Club is located in Icirrus. The Pokémon Fan Club is an organization spread throughout the Pokémon world, with at least one Club House in nearly every region. The Fan Club is basically a place for people to meet and chat about their favorite Pokémon and to show off their collections to each other. In general, the members are usually more oriented to unevolved, cute Pokémon.

If the player shows the chairman of the Fan Club a Pokémon, depending on how many levels it has gained since it was captured or hatched, he may reward the player with an Exp. Share, Cleanse Tag, or King's Rock. A member of the club will also rate the friendship of a Pokémon in the player's party.

The lone Team Rocket Grunt who stole the Machine Part from the Kanto Power Plant in Pokémon Gold, Silver, Crystal, HeartGold, and SoulSilver is revealed to live here, as he can be found in a house with his wife and son that can only be accessed during the winter. He says that while he had planned to revive Team Rocket, soon after returning home he fell in love and then married. His wife gives away a RageCandyBar, and says that RageCandyBars bring the family together, like his teammates from his old job.

In Pokémon Black 2 and White 2, the house is inhabited by a couple consisting of a former Team Magma Grunt and a former Team Aqua Grunt. A sound designer, presumably Shota Kageyama, is also found in the house, and can be engaged to change the background music to 10番道路 Route 10 (which is otherwise inaccessible in these games due to the absence of Route 10) for the duration of the player's stay in the house.

Each day, Wye (Japanese: ナンデヤ Nandeya) will invite the player to take a quiz. Every time, Aha (Japanese: ワカルデ Wakarude) will ask the player a question, and Ditoh (Japanese: セヤナ Seyana) always asks for a hint, which Wye gives. Upon answering the question correctly, Aha will give an Antidote to the player, but he will give a Parlyz Heal if the answer was incorrect. The answers are given via the easy chat system.

Inside the Pokémon Center, the Gentleman to the right of the nurse's desk is an item maniac who will buy stone-like items for a higher price than usual.

Main article: Icirrus Gym

The Icirrus Gym is the official Gym of Icirrus City. It is based on Ice-type Pokémon. The Gym Leader is Brycen. Trainers who defeat him receive the Freeze Badge.

Icirrus City is an average-sized city with a population of 34.

Icirrus City's population decreases to 26. This is mainly due to the Gym being closed.

During the post-game, each member of the Shadow Triad can be battled in Icirrus City once per season. They are all fought individually, in a Single Battle, Triple Battle, and Rotation Battle, respectively. If the player has fewer than three Pokémon remaining, or declines battle, the remaining opponents will vanish until the season changes.

Black arrived at Icirrus City at the conclusion of his training under Brycen, leaving only the Gym challenge where Brycen awaited. After winning the Gym battle, Black was then told of the advancement of the date of the Pokémon League tournament. Disgusted at the impossible task to qualify for the tournament, Black fled the Gym and the city.
