Well, I had kind of hoped for an expression of interest before I elaborated, but I do suppose I need to give the pitch a bit more in-depth than that.
This fic takes place about 1-3 years after the events of Teen Titans: Trouble in Tokyo (and also Ranma 1/2's anime adaptation). For context, in this fic, for roughly the past year, Blackfire has been bumming around the galaxy with Ranma Saotome after the two of them were taken captive by the same intergalactic slavers and worked together to escape - he's actually been kind of a mollifying agent on Blackfire, softing the Tamaranean exile to more of an antihero. The two are lovers, but neither officially admits to being in love yet (they're both kind of damaged people) - there is an intended "backstory" type fic, but it's not pregchan relevant.
The fic starts with a confused Blackfire receiving an official summons to Tamaran, where she encounters her sister. They've been summoned by their brother, Wildfire - ignoring the TTG comics, this depiction of him is basically a selfish wastrel as well as the family weakling. He is contesting Starfire's claim to the throne (even if she did give it up to Galfore) by invoking an ANCIENT clause in the royal laws that boils down to a challenge of fertility: whichever of the three siblings can produce the most biological offspring within 1 year of that day will be crowned the Grand Ruler of Tamaran - this supersedes all other laws. Neither sister backs down and so the challenge is made.
In the privacy of her room, Blackfire vents to Ranma; this challenge is obviously rigged in her brother's favor, since males can produce offspring in far greater quantities than females. But she's adamant about joining, mostly out of spite and a competitive streak. If she has any kinky thoughts about being pregnant (or soft ones about being a mom), she keeps them to herself. Being her partner/boytoy, and hyper-competitive in his own right, Ranma agrees to help out, and even points out that Blackfire has three routes she can pursue to try and achieve victory:
1) Dose herself with alien fertility drugs, allowing her to conceive and carry way more kids in one go than would normally be possible. This is the "hyperpreg" route, obviously. Most obvious route, but also not guaranteed to work.
2) Go to Earth and see if it's possible to use Jusenkyo's Spring of Drowned Man in some fashion to equip herself with functional male genitalia; the contest is to have biological kids, it doesn't say she has to *carry* them, after all.
3) Dip in both options 1 and 2. This is the most complicated, since if Blackfire is pregnant herself, she *has* to see if it's possible to modify Jusenkyo's Spring of Drowned Man to turn her into a hermaphrodite Tamaranean instead of a male one, because otherwise, well, she'd lose the babies she herself was carrying.
As I said in the opening post, I'm struggling with which option to choose, even if it's only between options 1 and 3. Any opinions?
For the curious, Darien-Shields never completed Succession, only writing 8 piecemeal chapters that broadly set up the story, but they did post their plans for the ending. Basically, Wildfire would have lost outright, because Blackfire would turn out to have bribed/intimidated all of his concubines into getting pregnant by other men behind his back, so he fathered no offspring. Blackfire would have turned up enormously hyper-pregnant by unknown father(s), courtesy of abusing a bunch of Tamaranean fertility boosters (which would have led to some "issues" with the kids). Starfire would have been hyper-pregnant with Robin's kids, but not so much as her sister... but Starfire would still win, because, thanks to a magical mishap by Raven, Raven would also arrive equally as hyper-pregnant with her and Starfire's kids, and whilst neither Starfire nor Raven are individually as big as Blackfire, their combined kids total beats out Blackfire's.
