The designs of all the random generic trainers have changed quite a bit throughout the series, and I'm kind of curious what are some of your favorite designs in the series.
Some of my favorite designs include the BW/BW2 Ace Trainers, XY Female Swimmers, ORAS Male Breeders, and the Rangers from XY are pretty cool, and I think the ORAS Lass is designed pretty well.
What about you guys?
