I have recs in the comments of one of jjhunter's posts linked above and I have apparently forgotten to rec blackkat entirely: I'm reccing the Naruto works (though Kat's clearly gotten massively into Star Wars recently) reverse, backslide, and Stormborn. The first two are what if someone time-traveled from [sometime well after I stopped paying attention to canon, and probably well AU from canon anyway]; in backslide that person is Naruto himself, landing months before smol!Naruto graduates the Academy and adopting his "cousin" at the earliest opportunity, and in reverse that person is the Kyuubi no Kitsune, landing years before smol!Naruto graduates the Academy and promptly kidnapping smol!Naruto and, over the course of the fic, every other jinchuuriki and Uzumaki in the whole damn world, thus upending everybody's politics. Stormborn is, what if Naruto was the reincarnated Uzukage, and ran away from Konoha with Gaara in tow basically the moment he figured out what that meant, in order to rebuild Uzushio and (mostly as side effects) kidnap most of the other jinchuuriki and upend everybody's politics.
