Quick Answer. As of PokÃ©mon X and PokÃ©mon Y, the only method of evolving Haunter is to trade it to another player. Once the other player receives Haunter, it evolves into Gengar. The other player can subsequently trade Gengar back to the original player. Haunter evolves from Ghastly at level 25.
While there are various ways to make PokÃ©mon evolve (using evolution stones, increasing happiness level), it can be a challenge to find out how to evolve starters Rowlet, Litten, and Popplio and at what level they will evolve. Rowlet evolves into its second form, Dartrix, at level 17.
