Just something that I was posted on a different forum that I also decided to put here. The GEoM comes across a baby Usagi either after by thrown into the SM mangaverse or Usagi somehow being cast into the Warhammer 40k reality. Being what he is, the GEoM is more then capable of divining Usagi's true nature, cue him promptly adopting her and several decades/centuries down the line every other power outside of IoM within the two realities getting epically shafted. ...Though I got to admit I feel a slight bit of pity for Mamoru if he still ends up with Usagi given that the 'meet the family'thing is probably not going to go well for him if the any of her brothers mange to show up for it and can keep from sniping at each other Not to weigh in one way or the other but Usagi probably would work best as her 'normal' self if simply for the fact that I'm sure that GEoM would've been fairly paranoid about the baby Primarchs back when they where in his care and would have done his damn best to keep what amounts to a cosmic entity from being reborn in one of them. Which means that Primarch!Usagi wouldn't have the Ginzuishou and would a lot less powerful when it comes personal power, especially going by the manga where by the end she's become the shoujo equivalent of a proto-GEoM. Where as if he meets Usagi after she's born, the GEoM will still probably be a bit paranoid about her but will also be to see that she is neither a daemon or some other cosmic horror (at least for humanity) but something closer to himself. And the GEoM is also more likely to be more open about the truth of the Warp to her by sheer necessity. And I really can't see Usagi not spilling the beans to at least Magnus post-Nikaea in order to explain the GEoM dislike for sorcery, and Horus if just accidentally. Which in itself could have some massive consequences... ---- Please note that idea uses the manga-version of Sailor Moon and not the dubbed or anime one. The Sailor Moon manga was to use a robot analogy is basically the Gurren Lagann of magic girls. At the start of the series the only things that Usagi can do is throw her tiara at her enemies and the physical capabilities to launch herself into orbit. By the end of the first season, she's with Mamoru help capable of resurrecting the entire planet after every one dies. By the Second arc her power has jumped again to the point where she can suddenly Death Star a world. And at the end of the entire series she's powerful enough to block the combined attacks of all her Senshi after Galaxia resurrected them as her slaves, go on to fight Galaxia, get her wings ripped off, and then help resurrect the galaxy.
