I got the idea of Ranma being the son of Typhon and Nodoka. That is the real reason why Ranma's mother agreed to Genma taking Ranma on the training trip. To keep him safe from both monsters and Gods. It could explain the rivalrly between Ryoga with Ryoga being the son of a God. Don't know where in the series timeline of the Percy Jackson bookds it would be for Ranma and the Nerima Wrecking crew to meet the Camp Halfblood heroes. It would be funny to have Kasumi being the favorite daughter of Ares. So what do you guys think? Plausible?
