This is an idea that has been in my head baging to be let out, since I have other thing I am working on I thought I would post it here in hopes that someone would write it. It's a Ranma / Sailor Moon cross in case you can't guess from the name.
One day while 'training' with Happosai Genma gets badly hurt and ends up in the Hospital. There he meets and falls in love with a young intern named Uma* Mizuno and they get married and have two kids Ranma and Ami. Now for the training trip there are two ways it could go:
1. Genma could say that he is taking the kids for a short training trip and disappears. It takes Uma a year to find them after she does Genma convinces her to come with them.
2. Happosai is mad at Genma for 'being disrespectable to his master' ei not helping him steal pantys any more and attacks his family and they are forced to leave.
Anyway they go to Jusenkyo Ranma and Genma both get the same curses as in cannon and Ami gets a otter curse. They stay with the Amazons for a while and while there Herb sees Ami and decides he is in love with her. After a few months they head back to Japan to see the Tendos and Ami meets a certain black cat.
*I don't know Ami mother's first name but I saw this name in a fanfic.
