Post your transgender transformation ideas for shows that usually don't have transgender
D.N.Angel
D.N.Angel Magical Girl, The return of the Dark Mousy doesn't go as expected, when it turns out Daisuke Niwa grandmother was a Demon Hunter and the two genetic traits got mixed up.
On the day Daisuke was supposed to turn into the Dark Mousy for the first time, he had been carrying a ring his grandmother had given him and told to give it to the girl he was gonna marry. After being rejected by Risa Harada he slips the ring on his finger without really noticing. Later that day, the heart-broken Daisuke undergoes a strange mutation that not only changes him into another person, but also into a magical girl!
His mother Emiko is surprised, as she had actually been expecting his son to change, but to end looking as a boy. Thankfully, after talking with his grandmother, he is able to change back by removing the ring and cleaning his mind of all thoughts. If his body tries to change without the ring he just feels great pain without changing, and as he happens to NEED to change everytime he has romantic feelings for his crush or whenever he thinks too long about her, and he happens to be an hormonal teen, he has to resign himself to carry the ring around.
It seems now Daisuke Niwa has to deal with both being the genetic reincarnation of a famous thief, and fighting Demons as a magical girl so the world doesn't get destroyed. Also there is another personality in his head called Dark, that continually protests the fact he can only take over when Daisuke turns into a girl, and that he is a thief, not a demon hunter and than that damn demon hunter outfit shows too much skin!
Status: Just posting the idea to see if someone will do it, I haven't read that manga much. Personally I think Dark reactions about being a girl would make it hilarious.
Bleach
Strawberry a genderbender bleach fanfic. Ichigo had a great sense of dread, of impeding doom, something just wasn't right about him since Orihime had healed him, after trying to get his Shinigami powers back he not only becomes a Shinigami again, but also female. Will he lose his powers to change back into a guy? Or will Ichigo stay female and go to Rescue Rukia?
Status: First chapter done and can be found here

Slayers
Not a real cure Zelgadiss Graywords has been looking for a cute to become a human for years. When he hears about a spell that turns horrible fish monsters into humans he decides to try it onto himself. Only it turns out those monsters only take human form because they are an all female race and they need to breed with human men to survive. So poor Zel ends being human, but not the way he wanted. But hey the spell isn’t permanent right? What do you mean she can only change back after having sex?
Status: Again, another idea posted so people can use it. Not a very original idea and similar things have done before but I figured I would contribute my grain of salt.
