RENEE OLSTEAD. What a difference a day makesTwenty-four little hoursBrought the sun and the flowersWhere there used to be rain. My yesterday was blue, dearToday I'm a part of you, dearMy lonely nights are through, dearSince you said, You are mine.
Quick Answer. As of PokÃ©mon X and PokÃ©mon Y, the only method of evolving Haunter is to trade it to another player. Once the other player receives Haunter, it evolves into Gengar. The other player can subsequently trade Gengar back to the original player. Haunter evolves from Ghastly at level 25.

If you have a friend with this game you can trade it back and forth so that you can keep your Pokemon but still evolve it. User Info: TheMightyK. TheMightyK - 8 years ago 0 0. It evolves via Trade, but dont trade via Wi-Fi cause you will never get him back....
