Haunter only evolves into Gengar through trade. If you're using a generation 4 Pokemon game you can deposit Haunter into the GTS and trade for any other Pokemon in the GTS, then take back your Haunter and it will evolve.
That is unfortunately impossible.
No, you need to trade it.
gastley evolve's at level 25 trade hunter to get gangare
im guessing u mean haunter, and u must trade it to evolve it into gengar, which sucks if u dont have anyone to trade with, or are playing a rom.
Haunter evolves when you trade him to another game, the same goes for Machoke to evolve into Machamp ect.
you can evolve scyther by making it hold a metal coat which you find after beating the elite 4.make scyther hold it and trade it but then trade it back to you to make it evolve.

No, to evolve it you have to trade it without it holding an everstone.
You cannot evolve without trading, you should just trade with lots of people until you get a gangar
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.
To get GENGAR you trade with someone and after the trade is complete haunter will evlove into gengar
To evolve haunter u have to trade it. As soon as it is traded it will evolve into Gengar.
Any level! You just have to trade it, to evolve it!
You need to trade it to another game to evolve it, it's okay if you trade it back afterwards.
