Here's an animation with sound from Mankor (also known as Mainkore), featuring a heroine, Erza Scarlet from Fairy Tail, being transformed into a rather monstrous dragon. I can't post a downscaled version of the vid here, since the forum isn't co-operating. Instead, I've posted some screencaps of the video.
