Iwane one of the official animators sometimes draws or retweets sexualized art of pokegirls. While this is a reference to Movie 13 when Zoura transformed into Dawn, it's still essentially Dawn sticking her ass out.

I didn't know official Pokemon staff were allowed to post this stuff. Makes me wonder if they've drawn lewds of all Pokegirls but keep in privately because they'd get fired if they posted it online.
