Where to get Gengar in Pokémon Scarlet

To catch yourself a spooky Gengar in Pokémon Scarlet, you gotta look for its pre-evolved form, Gastly, or its evolution, Haunter. These ghostly Pokémon hang out in the wild areas that have a spooky vibe, like graveyards or caves. Once you catch a Gastly or Haunter, level up Haunter and it'll evolve into Gengar. Remember, the evolution into Gengar happens through trading Haunter with a friend. So, find someone trustworthy, trade your Haunter, and it will evolve into Gengar upon receiving it in the trade. Happy haunting!

Honestly, getting a Gengar is a bit of a hassle. You first have to catch a Gastly or Haunter, which is cool and all, but then you gotta find someone to trade your Haunter with so it can evolve into Gengar. I did this with a friend, and the trade-and-evolve process was smooth. Just make sure you pick someone who will trade it back to you unless you want your friendship to vanish like a ghost.
