There are a handful of Ghost-type Pokémon that you can find in Pokémon Brilliant Diamond and Brilliant Pearl. Gastly, Haunter, and Gengar are among the most famous as they are Pokémon from the original Pokémon games. But if you want to evolve Haunter into Gengar, you have to meet specific requirements. In this guide, we will share how you can evolve Haunter into Gengar in Pokémon Brilliant Diamond and Brilliant Pearl.
You don't need an item or special move to evolve Haunter into Gengar. Instead, the only way to do this is to give another player your Haunter. When you trade, Haunter instantly evolves into Gengar during the trade.
You can always ask your friend to give you a Haunter, and this is another way to receive Gengar. Regardless of how you do it, the trade must take place for Haunter to evolve into Gengar. Haunter doesn't need to hold special items, so you don't have to worry about that. You want to make sure you trade Pokémon with someone you trust to make sure you get Gengar back when the trade is over. Gengar is a useful Pokémon if you want to make sure it never gets hit by Normal-type attacks.
