Why do people always call Gardevoir a her when it has an equal chance of being a guy?
Because it has a dress as part of its body and looks very feminine. Ralts must be very gender confused. Ralts -> Kirlia -> Gallade is like gender whiplash.
Several civilizations have had a tradition of dressing young boys in dresses or other pieces of stereotypical female clothing for a large portion of their history, including Japan. As Medieval Europe was one of them, it kind of makes sense.
Oddly enough the only Gardevoir I have is male. --- Badge Case [Time Badge] StrifeHart is my OTP. services performed at BSC: 2 Riley's Boyfriend on the Pokemon BW2 & X boards. W1 FC: 4170 0917 6393
