no you have to trade him to evolve him
Haunter evolves into Gengar by trading lol
No there isn't.
Haunter can level up and evolve. It evolves by trading with another player.
It won't evolve without trading
There is no level, in order for him to evolve you MUST trade him.
Gastly evolves at level 22 then Haunter evolves by trading it.
there is no possible way to make him evolve with out trading. you have to trade to make kadabra, haunter, and many others to evolve
no, you have to trade, everybody who tells you something different is lying
Haunter does NOT evolve by level. You evolve Haunter by trading it with a friend, and then they trade it back to you. Hope I helped :)Haunter evolves from Gastly at level 25.Haunter evolves into Gengar through trade.Haunter evolves into Gengar by trading it.
