Like all other regions, Unova has a Pokémon Fan Club. In Unova, it is situated within Icirrus City in the northwest of the Unova Region. This club acts in a similar manner to the other clubs and just gives generic tips and statements by non-playable characters. However, the president of the Fan Club offers you incentives to raise your Pokémon.
When you first visit him, he will ask to see one of your Pokémon. When done, he'll jot down the Pokémon and the level it is at presently. Later, when you return, show him the Pokémon and he will make a remark and provide a gift based upon how much the Pokémon has grown
