Ideas:
1 Alternate Universe, When Ranma and Genma get to Jusenkyo the guide tells them that the training ground is closed. He takes them up a cliff to reveal why; it is a rare astrological conjunction, which triggers all the pools to flood creating a lake filling the valley. The guide explains that it will be a few days before the lake drains and a few months before the springs stabilize. Ranma however hears something from the lake, walks too close to the edge and falls in. The revelation is the true origin of Jusenkyo, it was once the lake where a dragon drowned. The dragon's power infused the lake and the springs that fed it, and when the lake dried up remnants of the dragon's shapechanging power reacted to form the curses. On that rare day of amplified mystic energy though, the original like reformed and if anyone who was sufficiently compatible fell in, they were given the form of a dragon. Enter Ranma.
Note: here's one reader's take on the story concept, Warning it's in spanish
2 Ranma gets tired of being so afraid of cats, and resorts to reading through a book on phobias. Systematic desensitization is easy enough for him to understand, so he invents a treatment based on it. First he throws together the most sedate relaxing kata he can imagine. He puts blurred pictures of cats on the Dojo walls, and performs the Kata until he can do it to full relaxation. Then he replaces the pictures with sharp cat images, then adds tape recordings of cats yowling, working his way up to where he can stay relaxed with a dozen cats loose in the Dojo with him. After a week or two he's lost his fear but has started having vivid dreams of being a cat. Then in a big fight where he wishes he could still use the Nekoken, he gets strong flashbacks of the dream, and figures out that he could voluntarily enter the Nekoken state by focusing his mind on the dreams.
3 Another supreme Ranma type alternate, this one would involve Ranma being thrown backward in time 13000 years, landing in an alchemists lab in Egypt, and dumping an incomplete preservation potion over himself. The interactions of potion and curse leave Ranma "Preserved", he doesn't age, his wounds repair themselves fast, and his physical condition never improves or deteriorates. Which means that as Ranma enters the world of the oldest martial arts, including the original Nekoken, he's forced to rely on his capacity for learning and innovation. After a fair time period the alchemists society he crash landed at figures out a way to precisely time a magic potion to put him into hibernation so he will wake right after he fell through the time warp.
4 Ranma learns about the Saotome family, and discovers that Genma is a martial artist because he had so little ability at the real traditional business of the family, theft in all it's forms. The Yama-sen-ken and Umi-sen-ken are adaptations of scrolls, which the thieves of the family have been using to record their tricks of the trade for generations. And the two special styles are adapted from the only scrolls Genma had any affinity toward. Ranma has the chance to look through the full set of scrolls, and with the Yama and Umi as inspiration he begins creating new techniques from other arts of theft. Eg: Pickpocketing would suggest several really effective "Look there goes Elvis" type techniques, some speed enhancing techniques, and maybe a way of creating air vortexes to draw things to the practitioner.
5 A horrible revelation about Genma, he's really a demon lord. In this story, twenty or thirty years ago a powerful demon lord lost big in a bid for power and ran to earth to hide. Earth however wasn't exactly welcoming, and demon hunters managed to spot him before long. So the demon lord, being a master of deception, created a near perfect human disguise named Genma Saotome. When the demon hunters tried to exorcise the demon's "victim", they actually sealed the demon inside his disguise shell just as he had planned. Of course Genma Saotome was originally designed to be a honorable compassionate and selfless individual, but when your soul's actually a demon, there's only so much a constructed personality can do. Anyway this becomes important when something manages to break the seal allowing the Demon lord his freedom. Which would lead to a truly ferocious father son confrontation.
6 Altered cliche, instead of someone showing up and claiming to be Ranma's fiancee, the new character showing up is Ukyo's fiancee. This guy had been engaged to her after Genma took off with the Yatai, and thus has a weaker claim than Ranma, however Ukyo decides to try acting like she was interested in him in hopes of getting Ranma jealous over her. Naturally she's furious when Ranma immediately starts looking for a way to help the two of them get together.
7 Darkish, In a world where the Amazons are as aggressive and proprietary as depicted in some ficts, Ranma accidentally contacts the spirit of one of the hundreds of martial artists who were killed so that the amazons could gain exclusive control over a technique they learned from him. Ranma helps this spirit craft a 'scroll of accusation' which if properly presented could call the amazons to trial for the acts of their ancestors. Of course Ranma is neither vengeful nor overly judgmental so he would probably be hesitant to use it unless the amazons kidnapped him to the village and tried to force him to marry Shampoo. And if the ghosts linked by the scroll could protect Ranma from the techniques that had been taken from them, it could conceivably make the entirety of Amazon Martial art worthless.
8 The counterpoints to Bitter End(Dark of course) A: Shampoo. Through whatever circumstances Ranma marries Shampoo, and they move to the Amazon village. Shampoo's initially happy, however she soon discovers that Ranma isn't just an expert at martial arts, he's a master at infuriating the village elders. He tries to be polite and respectful, but whenever he's asked to do anything he thinks is stupid, he tells the requester "This is dumb, what's the point?" And he refuses to accept any of the "Tradition dictates you must do this!" arguments, which infuriates the elders. Things get tenser as they start trying to pound acceptance of Amazon traditions into Ranma's head, but Ranma just sees it as a training opportunity. Essentially the fict would trace the opinion of Amazon leadership as it went from "He's annoying, but putting up with him is a small price to pay for the strong blood," to "I don't care if his children will be gods! Nothing is worth putting up with him!"
B: Ukyo. Through whatever circumstances Ranma marries Ukyo. Initially Ukyo thinks it's her dreams come true, the two of them managing a restaurant together, however Ranma spends almost all of his spare time practicing Martial arts, her attempts at getting Ranma involved in Okonomiyaki cooking are refused because he "Knows the techniques." Ultimately he either begins entering high standing martial arts tournaments (Street fighter anyone) or starts building a Dojo. Ukyo realizes that Ranma loves martial arts more than her, and begins a planing a way to force him to give it up. The fict being what it is, the plans would get more extreme until a mistake in one caused a great tragedy.
9 Ryouga is lost in the mountains, ranting about how Ranma ruined his life and how he's going to kill him in retaliation, and he's overheard by some ancient evil person (Or something like that) Looking over Ryouga and recognizing his strength, he offers him a scroll teaching a technique which should be able to kill Ranma, in exchange for a later favor of course. Naturally Ryouga accepts and immediately starts trying to master the technique. He in point of fact skips reading the part of the scroll that poetically describes what the technique does, and simply works through the training technique described. After a few weeks, he meets Ranma, they get into a fight, and Ryouga tries to end the fight using his own unperfected version of the technique. The blast seems less powerful than the ShishiHokodan, but Ranma collapses after taking one shot. Ryouga's joyous, until he realizes that Ranma's in a coma from the technique. Akane and other witnesses are not very thrilled. It's eventually revealed that A: the technique Ryouga learned was designed to instantly kill anyone it hits. B, Ryouga messed up the execution so instead of killing Ranma, it essentially knocked his astral body out of his physical body and Ranma isn't going to wake up unless his astral body can find it's way back. And C, because of the blast, Ranma's Astral body was thrown far enough away that he'll never make it back unless someone finds him and guides him back. Of course Akane is the only one with enough of an affinity toward Ranma to find him. Meanwhile on the astral planes, Ranma is wandering, trying to figure out what happened. He quickly finds himself getting into trouble with the locals, and discovering that his techniques aren't up to handling that trouble, forcing him to invent some new techniques.
And that of course ignores the fact that Ranma's body is still lying there, available for any possessing being who wants to use a Jusenkyo cursed body.
10 Ryouga learns that the members of his family are actually the victims of three curses: the curse of misdirection, which causes them to keep getting lost. The curse of passion, which makes them all hyper-emotional; and the curse of strength, which makes them so strong that a simple hug could send whoever their interested in to the hospital. The reason both of Ryouga's parents can't find their way is because the one alternative to curing the curse of strength, is to inflict the same curse on their partner, however the Hibiki curses can only be passed on all together. Ryouga then finds him in a predicament. In order to marry Akari, he has to either share the three family curses with her, risk killing her every time they act affectionately toward each other, or try to break the curses. He finds what he believes is a way to break the curses, of course breaking the curse of strength would mean that he'd suddenly drop well behind Ranma in terms of fighting ability.
Alternatively Ryouga could come across the family scroll explaining the method of sharing the family curses with someone marrying into the family, and mistaking it for a love spell, he uses it on Akane. Now she can't find her way anywhere, her emotions are all pumped three times more intense than normal, and she's become super strong. The last she's not to upset about, at least until she accidentally hurts her father or one of her sisters. So now she needs Ranma's help to get rid of the curse, she could either find a way to reverse the scroll, or find the source of the Hibiki family curse and break that.
11 Ranma learns to use the force! Not really, he just discovers a scroll explaining a technique to increase speed and reaction time. In reality, the technique enables the practitioner to see a few moments into the future, knowing what will happen before it does, which enables them to react incredibly fast. As a side effect of learning this, however they would start to occasionally see snatches of the not so immediate future. The scroll recommends that the practitioner go somewhere isolated where very little is going to happen until they start to get the hang of their foresight. Which isn't going to be possible for Ranma. So he now has to try coping with the troubles brought about as he keeps getting distracted by seeing moments of whatever future is most likely at that particular instant.
12 Ranma discovers that he's this destined being, the subject of many prophecies. Naturally he's not very accepting of this, until he notices that everything the student of prophecy tells him is accurate. Thing is the prophesies revolve around his confrontation with a group of fierce demonic beings, and he learns of the prophecy that he will face the master of them and die facing him. Now on the one hand, despite his hesitancy, he's begun to develop a healthy respect for prophecy, and he doesn't want to die. On the other hand, if he doesn't face the master, the world will be destroyed. I admit it's a steal from the last show of the Buffy the Vampire slayer first season, but I think it'd be interesting to see Ranma dealing with the fact that he's about to do something that he admits is almost certain to kill him. Also how everyone would react to this.
13 An alternate universe where Genma didn't make the Man among Men promise to Nodoka, and goes to visit her before going to the Dojo. Thus she's with them that first day. The Tendo's would probably initially spot her maternal aspect, thinking she was a lot like Kasumi. Then they would learn that: A, she took honor EXTREMELY seriously, (If she heard anyone talking about getting out of the engagement, out came the Kitana) and B, her idea of courtship emphasized voyeurism, groping, sneaking into the girls bedroom etc.
14 Lemon: Ranma accepts a challenge by a practitioner of anything goes Marital arts, and doesn't quite realize what the challenge involves till he's at the point where he has to go through with the challenge or admit defeat. Considering the subject and his experience, he looses big time. His pride won't let him not demand a rematch, and now he needs some help to train.
15 Lemon: Happosei realizes that he's starting to get weaker, and the panties aren't sustaining himself enough. So he prepares for a special rite he does periodically to restore his strength. It involves some setup with Ranma and the rest, and on performance, the rite puts Happi in a deep trance, while his Lust and Lechery radiates from him to envelope Nerima. Basically the aura will amplify the Lust of everyone, and absorb some of the energy of them acting on that lust. And of course as Happi's heir and the unknowing focus of the rite, Ranma is getting an extra dose of Lust force.
1 Washu gets so fed up with the stupidity of an earth scientist that she publicly denounces him, and winds up becoming the target of an enormous media blitz. She starts building increasingly stringent security measures, and discovers just how hard it can be to keep out Paparazzi and reporters.
2 One of Washu's old schoolmates decides to show up the "Super Genius" by figuring out the Lighthawk Wings, so they kidnap Tenchi. Ryoko has to tap her full strength to rescue him.
3 small lemon idea, TV continuity. Kiyone and Mihoshi are working to earn enough to pay all the bills etc, and Mihoshi creates problems again. Kiyone gets mad and this time she brings up one of the job adds she and Mihoshi had seen in the morning paper, either a veiled offer for work in prostitution, or as an actor in a pornographic movie. Something along those lines anyway. Later Kiyone calmed down, started looking for Mihoshi, and remembered what she had said. Ultimate after some searching she discovers that A, Mihoshi had indeed taken her seriously, and B, Mihoshi had finally found a job she enjoyed and was good at.
1 Ramia's little brother feels sorry for Misal, and modifies her transformation spell so that each time she transforms to and from Pixy Misa, she keeps a little more of Misa's vitality. Naturally both Misa and Misal start getting more than what was planed from each other.
2 The appearance of Tokimi's analog. Perhaps Earth and Juraihelm were originally the same place, however for unknown reasons they split into different worlds. In the Original world Tokimi was a queen with her two sisters Washu and Tsunami, however during the split her sisters both became part of the newly formed worlds, with their avatars constantly reincarnating themselves through different lives. Tokimi however remained in the few places between where the separation didn't happen, and she periodically appears in one or the other world to perform mysterious plots that no one else understands.
3 Based on the TV series. It turns out that Sasami's mother and father first met when she was a magical girl for the previous queen of Juraihelm. They've known about Sasami being Pretty Sammy all along, they just kept it a secret because that's ‘what their supposed to do'.
4 Rumia gets his chance to go on a date with Misal, of course Ramia decides to "help" her brother, and Sasami and RyoOhKi decide to try helping Misal. And of course a terrorist from Juraihelm manages to escape to earth.
1. A plan of Lupin and Co. gets disrupted by a flamboyant French girl who's apparently an old friend and rival of Arsine as she call him. In reality she's his sister, but they initially hold off on revealing it because of an old childhood rivalry, and they keep concealing the truth after Fujiko starts acting very jealous.
1 A few months ago someone did a short fict where Usagi learned about just what Japan did in China during WW2. It wasn't that great, but I did feel the need to find a way of intigrating Japans Bio-Warfare division into a Sailor Moon story. So here's the lineup:
The Vilians: like the 5:00 fairies in the Sailormoon SS movie, except they are born from and guardians of Nightmares. They feed on terror, and the century has provided them with a lot of food. Their main Anti-Senshi approach is to take a person, and infuse them with the essence of their nightmares, temperarily turning them into something out of their worst dreams for a time IE, Naru might turn into an energy draining monster, Usagi a parody of a super strict teacher, etc.
The leaders were humans who were responsible for incredible attrocities, then transformed by merging with the nightmares they had inspired. To make it a bit more personal, Ami's (Or another senshi's) grandfather had been a doctor who had been joined the army during WW2, and found himself asigned to unit 731. After the war he went home dedicated to practising benevolent medicine and trying to do enough good to counterbalance what he had done during the war. Then years later, the Nightmare warriors tried to recruit him by getting him to merge with all the pain filled dreams he had once helped create. To escape that, he instead turned inward and merged with all the guilt filed nightmares he had lived with since the war. So he's technically one of the enemy, but his loyalties are more with the Senshi.
1 Partially inspired by some of the debates about the chest sizes of various anime characters. Idea: Lina and Gaury are pursuing a fugitive who among other skills is a master of the magical equivalent of cosmetic surgery. He wants to distract them so he can get away, but he doesn't want to risk hurting them without knowing it would finish the job. (If their annoyed they'll give up sooner than if they want revenge.) So he hits Lina with a breast enhancement spell and runs while she's unable to keep her balance thanks to her altered weight distribution. How would Lina react to suddenly being better built than Naga? How would everyone react to her differently?
2 lemon foundation: Lina learns of a magic spring that has the power to augment her breast size. She seeks it out, ignores the warnings and endows herself. Then she discovers that the side effects include massive amplification of her Libido. Alternatively she could discover that Nagi's "Perfect Body" was the result of such a magic spring. And once again the possibility of side effects arises.
1 Coyote arrives in town. (Despite being a protector, his practical joking tendency turns out to periodically turn everyone he protects against him. When this happens he generally takes a leisurely trip around the world, and by the time he gets back the people who got so mad at him are usually praying for him to return and deal with some problem they can't understand how to handle.) His behavior causes people meeting him to initially mistake him for Ataru, so he decides to visit him and ends up masquerading as his cousin. Or he could turn out to actually be Ataru's ancestor from one of his previous world trips (An explanation for Ataru's libido).
2 Lemon idea: Sakura receives a call from a shrine that Tomobiki high had visited several weeks ago. It turns out that while the shrine discovered that one of the evil spirit containment vessels had broken at the time and they suspected the spirit might have possessed one of the students. (They only just discovered the loss because it was a fairly low powered spirit) Sakura's investigation quickly spots it inhabiting Ataru, who has no problems doing whatever Sakura asks of him. (Except not trying to grope her) What no one had planned on is the fact that the evil spirit was a minor spirit of lust and lechery, and possessing the most lecherous being in the universe proved to have complications. When Sakura tried driving the demon out, she triggered an enormous release of lust energy from Ataru, sort of like an N2 sex bomb.
1 A prequel explaning Junpei and Celcia's antagonism: Celcia tried a couple of spells before the one which split while being translated, and one of the earlier ones had the effect of zaping her and Junpei with a high octane love spell. When the spell either wore off or was dispelled, they both immediately started with the denial and the denials got more personal about why a love spell was the only possible way anyone could want the other.
Ranma and the Matrix: Thinking along the lines of a crossover rather than a fusion. An advanced AI in what was once Japan discovered a method for cultivating and utilizing Chi in the human subjects, which could have boosted their power output dramatically. Ranma and the rest were part of an experiment, their real bodies were genetically modified for enhanced production of Chi, and Jusenkyo, and the forms of Magic were actually parts of the Matrix inserted to let the computers affect the matrix reality directly. Starting with that setup, here are a few elements to move the story:
1 Neo and co learn about this project to upgrade the energy generating capacity of the human species, and they make the trip to Japan to investigate.
2 When Jusenkyo was created, an agent got caught in one of the springs. So when the poor victim fell in, Jusenkyo disrupted the usual agent takeover, and led to a melding instead.
3 Jusenkyo, and perhaps the entire matrix, are the creations of an exceptionally creative AI who's distrusted by it's peers as a "Human Lover". It's loyal to the machines, but does have a soft spot for humans. And in Nerima, it's got much more influence than the rest of the world.
4 Ranma fighting an agent, or fighting Neo for that matter. Initially Ranma wouldn't have a chance, but he's always had a real knack for learning, and if he started getting the idea behind their ability to fight, it might lead to him accidentally awakening himself from the Matrix. With luck this would be within site of Neo who could trace him back to his body so he could be picked up in time.
Possibly a slow revelation type story by doing it focused on Akane a year or two after Ranma apparently died(Actually managed to awaken himself.) She's still feeling depressed about him being gone, and she also keeps getting the momentary sensations of artificiality about the world. Then she sees Ranma and starts searching for answers.
A variant on the Ranma/Jumanji fusion posted. The background is that Akane found the game, started playing it with Nabiki, and wound up getting sucked in. At which point she woke up in her bed, not realizing that she was now within the game. The series actually takes place inside the game, with everyone being a part of it shaped by her memories. However then someone on the outside finds and joins in the game, and manages to roll the dice to release her. She isn't particularly happy about being released though, and starts playing the game in hopes of being able to be reunited with Ranma. She does manage to release Ranma from the game with a roll, however he's now constrained by the rules of the game to be her enemy. He is still in love with her though, so he keeps thinking up ways to bend the rules to protect her from the game including the attacks he can't prevent himself from making against her. IE, assuming the game is really ancient. "Sorry Akane, I can't let myself fall for any trick more than once. Pointing out fallen coins, saying there's something behind me, asking my name, wait you haven't done that yet."
"What is your name?"
"Because of what we once shared, I'll tell you. I am called Ranma and Ranko, Saotome and Tendo, to some I was Ossage no Onna, to the Romans I was the knight of Eris, to the fae..."
Akane snuck away while Ranma listed every name he had ever been called.
Farscape with Guyver(Or Tekaman): Moiya encounters the successors of the Advent from Bio Booster Armor. It turns out that after abandoning the development of the Human species as the basis of an advanced bio-weapon, they took the technology and applied it to converting captives of various races into servile warriors. In the course of the encounter Criton gets captured and when they evaluate him for his conversion potential they come to realize that he's a representative of the ancient bio-weapon species their ancestors had created and abandoned so long ago. Possibilities from here include: 1 Criton being converted into an advanced Zoanoid/Zoalord but being able to overcome the behavioral controls through evolution after the Advent left, or with Zahn's help. 2 Criton escaping captivity before he can be converted, and accidentally stumbling into the area where the Bio Booster Armor was stored. 3 Criton being converted into a Zoanoid/Zoalord, and then stumbling into the Bio Booster Armor storage.
In any event the Advent's successors are fighting a loosing battle with various groups including the peacekeepers, and once they encounter Criton they decide that even if their ancestors were too afraid to utilize the human race, their willing to take the risk. So they head toward earth, and Criton has to convince everyone to try to get there first to keep them from turning the human race into a weapon to conquer the universe.
Alternatively the encounter could be with an alien species that utilized Tekaman technology on captives to create weapons, and they discovered that humans handled the process exceptionally well.
A sort of crossover between the Hercules/Xena continuum and 3x3 eyes.
The story is set in the Hercules/Xena setting, and begins with the Sanjiyan being natives of another world, where there had been a war that was literally destroying it. These survivors were able to form a dimensional rift and escape to the Hercules/Xena earth shortly before the final destruction. And of course, Xena and Gabriel happened to be right where the rift opened. Anyway the Sanjiyan were a lot less arrogant, aggressive, etc. than in the Manga. They just wanted to live in peace, but what are the odds the gods of that world would allow that. The more malevolent deities started thinking up various games to play with the new arrivals, but then they discovered that when the Sanjiyan are pushed, they could push back. Hard. Despite efforts to bring about peace by both sides, more and more incident's occurred till one god managed to push the Sanjiyan too far, which led to a confrontation where the Sanjiyan became the first beings in history to cause a gods harmonic core to disintegrate. Things went downhill from there, more unpleasant gods kicked the bucket. Then Hephestius or another brainy god/goddess discovered that the gods killed weren't really being destroyed the way Hinds blood or any of the god killing artifacts worked; their essence was being fragmented, and the Sanjiyan as a whole were involuntarily absorbing it. If they did it with to many more gods, it would make them go crazy. This lead Hephestius to ally himself with the Sanjiyan and create the magic prison for Aries(from the Xena episode) as an alternative to killing him. Ultimately peace is attained, but now the gods scale down their interaction with the mortal world dramatically, and the Sanjiyan created their holy land and lived there while the divine essence fragments gradually turned them and their descendants into the psychos from the manga.
Tenchi and the Forgotten Realms, the Finders Stone series specifically:
It's not really a plot, just looking at Tenchi and Azure Bonds/Songs of the Saurials, Alias and Ryoko have a lot in common, and so do Finder and Washu. Any story where they met and got the chance to chat would certainly interest me.
Devil Hunter Yohko, Buffy the vampire slayer: Buffy is given the opportunity to go to Japan as an exchange student, and meets Yohko. Lucky thing too, since a group of vampires have arrived as well and Yohko has trouble handling them. (Yes Vampires are less powerful than the demon's Yohko fights, just remember that, unlike the demon's she fought they live here on earth and so have the time to plan and prepare themselves so as to make the most of their strengths. And some have guns.) The leader is the only vampire slayer to ever become a vampire, and no vampire has ever tried it again because she's as insane as she is powerful. Recently though she has had help from a lesser demon who stabilized her mind, now that she's just emotionally unstable rather then jumping from delusion to delusion. She's preparing a ritual to become dramatically stronger which requires the blood of the active Devil Hunter.
Tenchi and Silver Surfer:
Basically beginning with the assumption that the two continuums are separate, this story starts in Marvel where Galactus summons his ex-herald to him because. Basically Galactus has long been aware that his appetite has slowly grown over the millennia, and despite constant study has not been able to stop it. Now however he has acquired a clue about Washu's existence, and wants his first herald to track her down and get her help in figuring out how to overcome the problem of his growing hunger.
1 Who in Ranma corresponds best to what?
Akane- I'd say an Ahron of the Children of Gaia. Think about it. She's full of rage, but when she's not acting on that rage she's kind, she's forgiving, she's compassionate and trusting.
Ranma- Akashik Brother.
Genma- An Akashik Brother, he was initially a very promising adept, but something went wrong during his second seeking, and he never really improved afterward. When Ranma awoke at the age of five, he initiated his plan to start the long training trip. He believed that he could teach his son to attain the capacity he himself long ago lost the will and courage to reach for himself.
Ryouga- Well, there's lots of possibilities, (a good thing about White Wolf's games is the fact that there's so much you can do with a little creativity). A Brujah vampire is obvious, likewise an Ahroun get of Fenris or an Eshu or Redcap from Changeling. Having him be a golem who turned out more lifelike than planed could also be a fascinating approach.
Actually the changeling angle is pretty good from the stance of changeling emotions tending to be more intense than for humans in and of itself. Also it could offer an alternate take on Ryouga's relationship with Ranma and Akane. Ryouga might well be acting as the muse for Ranma's martial ART, with the reward of soaking up glamour from Ranma every time he uses a technique he was inspired to create by a fight with Ryouga. What's more, he could have also tried to formulate a muse relationship with Akane, only to find himself in situations where he needed Glamour so badly he wound up Ravaging her instead. Which is one of the reasons she wound up falling into the background martial arts wise. Also why she's so consistently failed at so many other skills.
The Kuno's are probably either Marauders or Silver fangs who're REALLY exhibiting the effects of inbreeding.
2 The Super Martial arts from the series are actually a sort of hedge magic; a way that sleepers can tap the potential of their avatar and perform a limited form of static magic. However one day Ranma Awakens, and suddenly he's got troubles. His skill with Martial arts would easily translate into the founding understanding of Forces, Life and possibly Time(from the Tenshin Amaguriken). Only at the basic level, however. All of his techniques require more knowledge than he has to work dynamically, and he can no longer work them statically(A failed attempt to perform the Tenshin Amaguriken triggered a paradox flaw causing him to leave afterimages as he moved. He was able to win the fight with it, but it wasn't exactly reproducible.) Fortunately his avatar appears to him in the form of his female reflection and persuades him to go on a journey to master his new ability and this first seeking ends successfully at an Akashik Brotherhood chantry.
Tenchi WOD:WtA: Tenchi's paternal grandmother shows up at the shrine, A real wild old lady in more ways than one, she and Katsuhito don't get along at all. Eventual revelations show that she's a werewolf, also that Tsunami had been subtly manipulating each generation of the royal Jurai family to create a champion with the power of the lighthawk wings, but when Yosho's daughter married Noboyuki she was still expecting it to take five to six more generations. However something unusual about Noboyuki's bloodline(Werewolf kinfolk) enabled her to complete her goal with Tenchi. He could as a result wield the lighthawk wings, but when that ability awoke within him, his Garou bloodline and ancestral Rage also began to awaken.
Sailor Moon WOD(Sort of) Instead of a direct crossover, contemplate a Mage scenario-involving Marauders who's quiet is based on the Sailor Moon animated series. Eg: A cyborg for Interion X becomes disillusioned with the Technocracy vision of the world, remembers the show Sailor Moon that she watched when she was younger and wishes the world were like that. Then her avatar appears in the form of a cat with a crescent moon, and tells her it could be while offering her a magic pen. So is born Sailor Autochthonia.
And in point of fact any crossover could simply involve a WOD character being thrown into an Anime realm by the winds of a Paradox Storm.
Pokemon WOD:MtA: Not a story plot, but a scenario concept. The origin of Pokemon began when a Void Engineer ship got into a big fight with the Zigg'raugglurr, and wound up crash landing on the Pokemon world several thousand years before the fight started. In the crash the stores of Tass ruptured and spilled into the environment. This world had much less free quintessence floating around so the influx was significant, and it had a profound effect on the native life. Many of the species were affected by the Tass, beginning the evolutionary road which created earth's Thumavores. However the limited supply of Tass coupled with the world's quintessence poor nature caused the pre-thumavore species to evolve into Pokemon instead. Pokemon were similar to Thumavores in many ways, however the limited tass supplies had produced species who used quintessence incredibly efficiently.
Now as far as the human element goes, even in this quintessence poor world there were people with exceptionally strong avatars. Some of these people discovered how to link with Pokemon, forming a symbiotic bond with them. The humans of course gained the advantage of having a Pokemon ally, the Pokemon found that their connection to Prime was enhanced by the link, which enabled them to gain strength at an much greater rate. Initially there were very few people with the capacity to form the link with Pokemon, and for them forming the link was difficult and time consuming. Until scientists invented the Pokeball, they didn't understand the link, but the ball acts like a catalyst, enabling people who's avatars are weaker than the old masters to quickly and easily link with Pokemon.
And as far as a series approach: A Void Engineer rescue team finds the ship, and the world. They quickly realize that A: the entire human population are the decendants of the ships crew, and B: Pokemon have tremendous potential value. So they decide to establish a secret presence, and invite in some of their progeniter friends. One discovers that Ash has awakened, and decides to pass along some secret training. Of course things go from quiet to loud soon. Possibly the void engineers were Baribai, perhaps a Marauder passes by, perhaps the Progeniters just decide they want to create a Gravity manipulating Pokemon.
