Pokemon Let’s Go Gengar – How to Get Gengar

In order to get a Pokemon Let’s Go Gengar, players will need to catch a Haunter first. After this, they’ll need to trade it—preferably with a friend so that they can trade it straight back, or at least swap their Haunter for yours. This is because Haunter only evolves when it’s traded, which has always been the case in Pokemon. Other Gen 1 trade evolutions include Machoke into Machamp, Graveler into Golem, and Kadabra into Alakazam. Therefore, this guide works for all of these Pokemon, even though it only uses Gengar as an example. Here’s a guide on how to get Gengar in Pokemon Let’s Go Pikachu and Eevee.

Pokemon Let’s Go Gengar – How to Get Gengar

As mentioned about, in order to get Gengar in Pokemon Let’s Go, you need to get Haunter or Gastly first. If you get the latter, you’ll need to evolve it into Haunter before you can get Gengar. Gastly evolves into Haunter at level 25, so this shouldn’t be too difficult to do.

However, in order to get Gastly or Haunter, you need to know where to catch them first.

Pokemon Let’s Go Gengar – How to Get Haunter

Gastly and Haunter can be found shortly after you get your third Gym badge. After getting the Secret Technique “Chop Down” from the Captain of the S.S. Anne and taking on Lt. Surge in Vermilion City, the player will meet Misty outside of Surge’s Gym. Here, she’ll take you to Diglett’s Cave, which you can then go through (It was previously impossible to go the whole way back to Pewter City),

On the other end of Diglett’s Cave, you’ll bump into one of Oak’s aides, who will give you the Secret Technique “Light Up.” Your rival will show up soon afterwards and teleport you to the east of Cerulean City. Continue east from here and you’ll reach Rock Tunnel, which would be pitch dark if not for “Light Up.”

Lavender Town is on the other end of the Rock Tunnel. This town is home to the infamous Pokemon Tower, which is a seven-story building that serves as the home to Gastly and Haunter, as well as some Zubats, Golbats, and Cubones. Most of the Gastly will already be in the mid 20s, so catch any of them and you’ll have a Haunter in no time. It’s best to try to chain a few together, as the more you catch in a row, the higher your Gastly combo will be. At around 10, you;ll start to encounter “Amazing Stats” Gastlys, which will grow up to be much stronger Gengars. Although you can catch Haunter, it’s best to catch a Gastly and evolve it, as the stats will be higher this way.

Pokemon Let’s Go Gengar – How to Trade in Pokemon Let’s Go

In order to trade Pokemon in Pokemon Let’s Go, you’ll need to adhere to the following instructions:

  • Open the menu by pressing X.
  • Go to communicate, which is the second option from the right.
  • Click “play with other players” and then select one of the two options based on whether or not the player is far away.
  • Click “link trade.”
  • If you’re in contact with the other player, decide on a code using the Pokemon symbols there. For example, if you both choose “Bulbasaur, Pidgey, Jigglypuff” as your three-Pokemon code within a few seconds of each other, you’ll be paired.
  • Select your Haunter and click “offer Pokemon” and then “confirm trade.”

While you can trade with random people by selecting a random Pokemon code, it is unlikely they’ll give you your Haunter (now Gengar) back, so unless they offer a Haunter of their own in exchange for yours, try your best to arrange trading with a friend. Again, this trading option works in order to evolve Kadabra into Alakazam, Graveler into Golem, and Machoke into Machamp, too.

So, there you have it—a complete guide on how to get Gengar in Pokemon Let’s Go, starting with how to get a Gastly or a Haunter and then detailing the way in which you can instigate a trade. If you’re looking for people who want to trade, there are plenty over on Reddit, but be careful, as they might not be as reliable as they think. Again, the safest way to ensure you get your Gengar back is to trade with a friend.
