You have to trade with a friend at a pokemon center. I suggest trading kadabra for hunter. They will both evolve.
if you have a medicham you can trade a girl in snowpoint city for a hunter and it'll evolve into a gengar. Or, you can trade a hauntur with another trainer and it will evolve.
You have to find your friend, you trade your Haunter with another Pokemon and when the trade is done Haunter will evolve.
Haunter doesn't evolve at a level. It evolves by trading with another trainer.
Haunter doesn't evolve into Gengar by leveling it up. You have to trade it with another player for it to evolve. A good way to do it is to level your Haunter up until it learns the moves you want it to know, then trade it to a friend and then ask your friend to trade it back. Voila!
