You trade Haunter it it will become a Gengar.
I assume you mean Gengar and you get it by trading a Haunter with someone, once traded it will evolve.
It doesn't evolve. Gengar is a final evolution.
IT is a trade evolution.
You can't get a wild Gengar, you have to catch a wild Ghastly, or Huanter and evolve it. For more help visit Pokemon.Marriland.com (DISCLAIMER: I DO NOT OWN POKEMON.MARRILAND.COM OR ANY POKEMON TRADEMARKED BY NINTENDO!)
