Ghastly is a Ghost/Poison-type Pokémon that has been a staple part of many teams since Kanto. Naturally, Pokémon Scarlet and Violet did not forget to include it. Evolving Ghastly into Haunter is easy, but if you’re wondering why it takes forever to evolve Gengar, this guide can’t help you.
Why won’t my Haunter evolve into Pokémon Scarlet and Violet?
Haunter does not evolve to Gengar upon leveling up, it evolves to trade. This means you need a second copy of the game or a trusted friend to return your evolved Gengar after trading with them. If you want to trade online, you need a Nintendo Switch Online Membership. But you can always trade locally without a subscription. That’s why some trainers like to buy both copies of the duo Pokémon titles!

Haunter and Gengar share the same movesets, the only difference being the stat boost. So if you can’t find another trainer to trade with, you can continue to level up Haunter until he finds a way to trade you.
Is there any other way to evolve Haunter without trading?
In Pokémon Legends: Arceus, there used to be an item called Linking Cord, which allowed trainers to evolve Pokémon that needed to be traded. Unfortunately, this item is not present in Pokémon Scarlet and Violet. Core titles with two games, like Sword/Shield, greatly encourage trading.
Then again, this could be because completing the Pokédex is an integral part of the Pokémon Legends: Arceus experience. And Pokemon like Gengar and Machamp can’t evolve without trading.
