In fanfics, the catgirl could be a catalyst for character development. Her presence could force the other characters to confront their own prejudices or fears. For instance, if some characters are initially afraid of her because she's a catgirl with magic, they could learn to overcome that fear and accept her as a friend. Also, she could introduce new elements to the Ranma 1/2 world. Maybe her magic brings in a new type of martial art or a different way of looking at things.
The magical catgirl can also be a key part of the story's plot. She could be the target of a villain who wants to steal her magic. This would then set off a chain of events where Ranma and his friends have to protect her. Or she could be on a quest to find a way to control her magic better, and Ranma and the others join her on this journey, leading to all sorts of interesting adventures and interactions along the way.
One idea could be to focus on the comical situations the catgirl character gets into in the Ranma 1/2 universe. For example, she could be constantly mistaken for a regular cat and end up in all sorts of wacky adventures around the Tendo Dojo. Another idea is to explore her magical abilities in a more family - friendly way, like using her magic to help out the other characters in the story when they're in a bind. Maybe she uses her magic to cook a huge meal for everyone when the regular cook is out sick.
Another aspect of the reader's role could be as an explorer. The Ranma 1/2 world is full of strange and wonderful things, and Saffron is a part of that world. The reader, through the fanfiction, could explore this world with Saffron, learning about his powers, his past, and the secrets of the Ranma 1/2 universe along the way.

One interesting Ranma 1/2 crossover fanfic could be a crossover with 'Inuyasha'. In such a fic, Ranma's martial arts skills might be pitted against Inuyasha's swordsmanship. Maybe Ranma gets transported to the feudal era where he has to deal with demons just like Inuyasha. Another could be a crossover with 'Sailor Moon'. Picture Ranma and the Sailor Scouts teaming up to fight a common enemy. The contrast between Ranma's chaotic gender - changing and the Sailor Scouts' more traditional heroic personas would make for an interesting read.
