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 when traded to another Generation IV Games (These include Diamond, Pearl, HeartGold, SoulSilver, or Platinum.)
Haunter will NOT evolve into Gengar no matter what level you train it to, or if you use any sort of evolutionary stone.
For God's Sake, Haunter does NOT evolve into Gengar at Level 38 unlike other people say.
