Ralts has two evolutions. The first is Gardevoir, who can be obtained simply through leveling Ralts up. The second can only be obtained if your Ralts is male; it requires a Dawn Stone and can be evolved at any point after Ralts has evolved into Kirlia. Gallade is also part Fighting-type, making is an interesting Pokémon.

[But anyway...]

If you say so. I didn't have an easy time training mine; perhaps you will manage it better.
