Nezuko goes to the village to sell charcoal and when she returns home she finds that most of her family has been slaughtered. The only survivor is her brother Tanjiro and he's been turned into a demon. She must find a way to help him... (an AU where Tanjiro is the sibling turned into a demon from the start and Nezuko becomes a demon slayer. This will cover the Final Selection arc)
Miles is a vet and one of his clients comes in with an unusual patient for him after hitting the creature while drunk driving. The creature is a large robot cat, about the size of a cougar. He doesn't know it, but this is Ravage. A Ravage who has been separated from Soundwave and with little else to do decides he might as well stay with the human who fixed his leg.
Nezuko woke with a gasp. Her heart raced and her head pounded with each beat. She was remembering everything. It was a rush of memories jumbled together in no particular order; smells and tastes, sights and sounds, peoples and places. (Or the fic where Nezuko gets her human memories back after remembering her mother's lullaby and how I think that would affect things)
A stranger appears at the Kamado house in the middle of the night and they try to welcome him in out of the cold, but when he sees Tanjiro's hanafuda earrings he gets violent. (an AU where Tanjiro is the sibling turned into a demon from the start and Nezuko becomes a demon slayer. Tanjiro's POV that (mostly) follows along with Wasurenagusa)
Senjuro gets sick so Mitsuri takes Kyojuro's place to investigate the demon train. The crow doesn't find out in time so things go much the same, Tanjiro and the others finding Mitsuri and fighting alongside her to defeat the demon. And then Akaza comes on the scene and things deteriorate quickly when he refuses to fight her. (inspired by a tiktok, pure crack)
What ifs centered around Tanjiro becoming the demon instead of Nezuko and Nezuko becoming the demon slayer. First one: one potential result of the pillars meeting Tanjiro and how Tanjiro reacts to Sanemi stabbing him is just him bursting into tears. Urokodaki makes him think humans are his family after all, so when he realizes that one is hurting him...
Miles Lancaster, the ex-bestie of Sam? After finding a damaged Barricade everything changes for the young teen and he drags the growling 'con along for the ride. A Sparkling, Cons joining the Bots, and more! Mech/human later on. (Updated and changed version of TC)
Mikaela is the newest slayer. Miles is her watcher. They've been working together for years, but it's becoming harder to hide her secret from Sam. Bumblebee and Sam fear the worst when Mikaela keeps disappearing, wondering if she's cheating or involved with drugs, but what they find out surprises both of them.
The Heart of Gold had the Improbability Drive installed inside of her. It would, improbably, take a third parallel universe with Ford, Zaphod, and Trillian being the reason that Rose goes from her second parallel universe to her first, to her home. To the Doctor. The Heart of Gold, you see, is actually quite proud of herself for that improbable feat.
Bumblebee is a mech who played at a belief in Primus to appease his Prime. But when Sam and Mikaela get engaged the mech decides to search out Sam's old friend who just up and disappeared one day. What he finds in in the form of Miles Lancaster and his daughter will change how Bumblebee views the world for good. (Supernatural crap/people with powers. Questions. Sam & Miles are 25)
