Ranma, a canon gender bend! He's a boy that was cursed when he fell into an एनचांटेड pond during martial arts training, so he turns into a girl whenever he's doused with cold water, and back into boy when doused with hot water! :)
Please click the link, I can't post pictures on my iPad.
I couldn't find a pic of just Mio gender bendered, well I did but it wasn't very good to me, but here's Mio and Ritsu being gender bendered. I don't think there is an actual male version ऐनीमे but it looks damn real in this pic.
