Now, let me tell ya somethin’ about Haunter in that there game, Pokémon Let’s Go Pikachu. Ya see, Haunter is one of them spooky Pokémon, it’s a ghost and poison type. Now, if ya wanna know at what level Haunter evolves, I can tell ya this: it don’t evolve by level like most do. Nope! It evolves into Gengar, but not in a usual way.
First off, Haunter comes from Gastly, and Gastly turns into Haunter when it reaches level 25. That part’s easy. But gettin’ Gengar ain’t that simple. Haunter don’t just level up and poof, become a Gengar. Nope, in the old days, you had to trade it to someone else, and that’s how it turned into Gengar. But here’s the kicker – in Pokémon Let’s Go Pikachu, you still need to trade it if you want that Gengar.

Now, this ain’t like some other Pokémon where ya just wait for it to grow up a bit and change. Haunter is special, see? Once it becomes Haunter at level 25, ya got to find someone who’s willing to trade it with ya, then and only then, it’ll evolve into Gengar.
How to Get Gengar:
- Catch yourself a Gastly first, it usually shows up in them spooky places, like Lavender Town.
- Level it up to level 25, then it turns into Haunter.
- Now here’s the tricky part: ya gotta trade Haunter with someone. After that, it evolves into Gengar.
That’s how it works in the old games, and it ain’t much different in Pokémon Let’s Go Pikachu. If ya want Gengar on your team, you’ll need to find a buddy to trade with. But hey, Gengar’s worth it! It’s one of them powerful Pokémon, especially when you’re fightin’ them psychic types or fairies.
So, to wrap it up, Haunter ain’t gonna evolve into Gengar by just levelin’ up. You’ve got to do a trade with a pal. And let me tell ya, once you got that Gengar, you’re set for a lot of battles. Just remember, if you’re lookin’ to catch ’em all, trading’s part of the fun in these games!
