How to Evolve Haunter

To evolve Haunter into Gengar in traditional Pokémon games, you must trade it to another player. Once the trade is complete, the evolution triggers automatically. In modern titles like Pokémon Legends: Z-A and Pokémon Legends: Arceus, you can simply use a Linking Cord item directly on Haunter without trading.

Haunter relies on two distinct mechanics depending on the generation you are playing.

• Legends Series (Z-A, Arceus): Apply a Linking Cord directly from your satchel.
• Core Series (Scarlet/Violet, Older): Trade with another player via local wireless or internet.
• Pokémon GO: Trade to a friend for 0 Candy cost, or manually spend 100 Gastly Candy.

If you plan to keep Haunter unevolved for ZU tier competitive play, equip an eviolite to boost its bulk. This allows you to safely utilize Levitate to avoid Ground-type attacks.

The upcoming Pokémon Legends: Z-A continues the quality-of-life improvements introduced in Hisui. You do not need an internet connection or another player to achieve this evolution.

1. Obtain a Linking Cord from the Merit Point exchange or specific side quests in Lumiose City.
2. Open your satchel and select the Linking Cord.
3. Apply it directly to Haunter in your party.
4. Watch the evolution sequence begin immediately.

This method is ideal for solo players. Once evolved, you gain access to a faster special attacker. However, keeping Haunter with a choicescarf or focussash for destinybond traps remains a highly effective niche strategy.

In the Paldea region, the classic trade mechanic returns. You must coordinate with a friend or use online link codes to trigger the evolution.

1. Connect to the internet via the Poké Portal.
2. Select Link Trade and input a secure code with your partner.
3. Select Haunter and confirm the trade.
4. Your partner will watch the evolution screen.
5. Trade the newly evolved Gengar back to your game.

If you lack a trusted partner, search community forums for the standard Haunter-for-Haunter trade code. Ensure you check the summary screen before confirming to avoid getting scammed.

Before trading, consider your team composition. A ZU tier Haunter paired with Lycanroc or Vikavolt can effectively run nastyplot and sludgewave without needing to evolve.

Trade evolutions frequently fail due to minor oversights. Check these common blockers if your trade did not trigger the animation.

• The Everstone Trap: If Haunter is holding an Everstone, the evolution is canceled automatically. Always check the held item slot before initiating a link trade.
• Pressing the B Button: Unlike standard level-up evolutions, trade evolutions cannot be canceled by pressing B. If it didn't evolve, the issue lies with the item or the connection.
• GTS / Wonder Trade Glitches: Server delays sometimes prevent the animation from showing immediately. Check the Pokémon's summary after the trade completes to verify its species.

If you are using a Linking Cord in Legends Z-A and the game displays "Incompatible", ensure you selected the correct Pokémon. Haunter does not require any secondary items or specific moves to evolve via the cord.

Evolving maximizes speed and special attack, but Haunter retains a highly specific edge in the ZU tier. Its Levitate ability grants a crucial Ground-type immunity that Gengar lost in Generation 7.

Equipping an eviolite patches up its fragile defenses. You can pivot safely around Ground-type attackers and set up toxicspikes or fire off a STAB shadowball.

Alternatively, a lifeorb or choicespecs Haunter hits surprisingly hard alongside partners like Dugtrio, Mesprit, or Malamar. Evolve it if you need raw speed and Gengar's expanded movepool. Keep it as Haunter if you specifically need Ground immunity and ZU tier eligibility.
