Aww, I have Kirlia but I haven't trained an Gardevoir. (I don't intend to evolve my Kirlia)
Aww come on, maybe it can even wifi battle with NDS >_>
Is yours brave? You do know what means right? That it has a 10% higher attack stat, and a 10% lower speed, neither which does Vaporeon good.
I do have a 'brave' nature pokemon though - Bronzong. Except it's genderless so I can't name it you. XD I could train a Brave Steelix too, but no way you'd wanna be a Steelix right =o
