I've seen the strip in question. Is totes canon. ^__^

I have never figured out if Ranko is an actual female version of Ranma or if she's a copy of the original Drowned Girl. On the other hand, Shampoo's cat-form has purple fur, which I do not think cats normally come in, even in anime-land.

So maybe Ozai looks like Azula.

What does Bato want to do? /curious
