More Info below
Paramount Stars AU takes place within the Sonic Cinematic Universe. It is an Actors AU, so Sonic and Shadow are actors in Paramount Stars studios making the movies. They are both traumatised(tm) and transgender. Sonic met Shadow before the filming for Sonic 3 started and invited Shadow to join the movie. Over the two years of the movie production, Sonic and Shadow held feelings for each other before confessing on the night of the trailer release and becoming an official couple after the premier. Find out more at: @paramountstarsau
Sonic Rewritten AU takes place within the Modern Timeline, which are the games and IDW comics. It diverts from the canon after SA2, where Sonic and Shadow fell in love at first sight and was unofficially married by Dr. Eggman (they were out of options, okay?) during the Finalhazard fight. The rest of the timeline proceeds virtually unchanged, except for Sonic and Shadow being husbands (and more relationships beginning as well, because time actually passes here). However, the "canon" part of the timeline ends after the Metal Virus, and the rest of the AU largely follows the adventures of Sonic and Shadow's daughters, Hope and Light, and their friends (other fankids).

Highschool Sweethearts AU is self-explanatory. Sonic and Shadow are high school students at Emerald Academy, in Emerald Town who became boyfriends. Shadow moved to Emerald Academy from Central City Westopolis district, due to being harrassed and discriminated against because he was trans, and met Sonic on basically his first day at his new school. They got off to a rocky start but eventually became a couple by the end of Year 10 and are still dating well into their senior years - 11 and 12. This AU is largely a coping mechanism for my school life (and it is also very Australian High School themed) and will continue into an University AU. There isn't much content for it but im happy to talk about it.
Heaven and Hell AU is an AU where Sonic is a High Seraph from Heaven (heir to the throne) and Shadow was a demon, whose powers were unlocked by Black Doom during Shadow Generations (also heir to the throne - of HELL >:3). It begins when Sonic, formerly named Caelus, leaves Heaven because he felt unwelcome and bored there and found himself on Earth, during the time of the Ancients (from Frontiers). He helped them build their colonies and civilizations on the Starfall Islands and became a being of worship for them, but was ultimately forced into hiding by the Ancients as they wanted to protect him from The End. Sonic remains on the planet and survives through the rise and fall of empires and into the modern world. He earned his name after defeating Eggman for the very first time and has since taken on the title of Hero of the World and Seraph of the People. Shadow's story still stays true to the canon, but he discovers his demon lineage. Sonic and Shadow, both being divine beings, worked together to live in secret and their relationship started there. Their designs are on my blog somewhere, you'll find them lmao.
Shattered AU, like mentioned, is a Sonic Prime AU where there are different Sonic and Shadows in the Shatter Spaces. In New Yoke; Sonic is Solo and Shadow is Android. In Boscage; Sonic is Paradise and Shadow is Hawthorn. In No-Place; Sonic is Goldheart and Shadow is Darkquill. Each of the Shattered Sonic and Shadows reflect a milestone in Sonic and Shadow's relationship; New Yoke = Enemies, Boscage = Friends/Rivals and No-Place = Romantic. More info about each of the Sonic and Shadows can be viewed on THIS google doc file.
One Week AU, like mentioned, is a King Shadow x Jester Sonic AU. It is a fanfic that is currently being written, where Shadow and Sonic fall in love in One Week (hehe). You'll be able to read it on AO3 once its out!
The Litter AU, or simply, The Litter, is a timeline where Shadow and Sonic have 8 daughters. Hope and Light from the Rewritten AU was reused for this. The daughters, from oldest to youngest, are: Hope, Light, Faith, Life, Lavender, Sunflower, Iris and Hyacinth. They came in twins. Reference sheets are currently being designed and can be viewed once I post them!
Overcast AU is a Sonic and Rain-World crossover AU, with a post-apocalyptic theme. The environment, world and lore is similar to Rain World, but instead of slugcats, we have feral mobians. Shadow is from the human cities, above the clouds, and Sonic is a hedgehog surviving on the rain ravaged surface. Shadow escaped and fell to the surface, where he was rescued by Sonic and they would go on to become mates. You can read the first instalments to this AU on AO3!!
