The story behind her design is the Huns destroy Mulan's village, killing everyone...including her. Her ancestors send Mushu to retrieve the spirits of their fallen family. Upon collecting Mulan's spirit, she begs Mushu to restore her spirit to her body so she can defeat the Huns and avenge the death of her family. Mushu does so, but in order to bring her back to life, he must fuse his body with hers. When he does, he becomes a living tatoo on her body, his appearance altered by Mulan's rage and hatred for the Huns.
So Mulan is essentially a zombie fueled by revenge hahaha.
Your Wendy and Mulan are the only macabre/twisted fairytale princesses that I actually enjoy.
I'm usually not the kind of person to go for these things; but when I do, there's a certain flavor that I look for. You manage to hit that for most of these renditions.
That said, I've been looking at your Twisted series. Do you suppose you could add stories to the princesses you didn't give a tale to? They're very creative "twists" on the stories and make for excellent reading material. I would love to know the thought process behind all of them - like Belle and the Beast, Jasmine, Aurora, etc!
