Another pic involving Pokemon trainer Bennet. Here, Bennet is trying out his mega bracelet and a mega stone for his male Gardevoir. When their opponent uses Tailwind, something unexpected happens.
A while ago I found someone messing around with Pokemon game models. One of those included Mega Gardevoir having the dress parts removed. In this pic Gardevoir's legs are based on how the in-game model's legs were. It might look a bit weird, but I guess there's a reason it's in the same egg group as Wobbuffet and Dusclops.
