you have to trade a haunter and it will evolve into gengar.
gengar
In snowpoint city there is a girl who wants to trade one. Trade with her or catch a ghastly and train it. Next, trade and trade back haunter and it will be a gengar!!
No it won't Haunter only evolves when you trade across to a similar game, you have to trade it to Leaf green for it to evolve. It will migrate to Pokemon platinum and will stay as a haunter. To evolve it to a Genger on platinum, you must trade it to another platinum, diamond or pearl
Haunter evolves into Gengar by trading lol
electrive because venasaur and gengar are part poison, and electrive has better moveset.
Psychic Bryce has a gengar in Pokemon platinum.
Gengar is a powerful ghost type of Pokemon. In Pokemon Platinum it is possible to capture one by going to the Old Chateau.
