This topic isn't exactly what you might think from the title. I debated for a moment putting this in Ideas, but decided that the fact I'm seeking advice on putting something together for a concept meant that this belongs here in Research.
I had a concept for a fanfic develop after seeing the discussion for a Nanoha/Disgae crossover fanfic in the Ideas forum, which basically feeds upon my long-burning desire to see a "Ranma has a special heritage" fanfic where this *isn't* either through Nodoka or through Nodoka conceiving Ranma by cheating on Genma. The basic concept is that weird things have begun to happen around the Tendo dojo -well, weirder things than usual- and Genma has begun to act strangely, even for him. While Ranma is walking somewhere alone, puzzling over things, he is attacked by a monstrous creature- one so powerful that he can't defeat it. As it readies itself to kill him, however, Genma suddenly appears and curbstomps the monster with all the ease of Ranma trashing Kuno.
Ranma, naturally, demands to know what just happened (though it's hard to say whether he's more startled that Genma effortlessly defeated a creature that Ranma lost to, or at Genma actually fighting someone other than Ranma for the first time since they came to Nerima), and Genma explains things. Genma is a Disgae-style Demon Overlord- well, an EX-Overlord. Genma's throne was stolen and a vast deal of his power (at least half of it) was lost thanks to the efforts of some rival Overlords, and he fled to Earth to hide from them. Disguising himself as a human, creating the identity of "Genma Saotome, bumbling vagabond martial artist", he eventually fell in love with Nodoka, married her, and fathered Ranma. However, the enemies who cost him his throne have finally decided that it's time to get rid of Genma, and they don't care who they destroy in the process.
Before anyone brings it up, no, this is not one of those stories where Ranma's 'lineage' is what makes him so powerful- in fact, I actually have a scene planned where Ranma angsts (as much as Ranma can angst) to Genma about all his victories being false, as he 'cheated' with his demon power, only for Genma to flatten Ranma and bluntly tell him that he sealed away Ranma's demon side while Ranma was still in utero. What he's become, he earned solely on his human capabilities. If Genma was to unseal Ranma, which he's unwilling to do, Ranma could become much more powerful.
I might also have it that one or more of the other Nerimites has non-human blood in their veins, though they will also be either sealed or so watered down that they have no real benefit from it.
Anyway, to go with this story, I'll need to develop an infernal cosmology, explaining/examining the demon dimension(s), demonic society, and demonic nature (forms/breeds, abilities, personalities, etc). Is anyone interested in giving me a hand with this?
