I don't know that any of them are actually usable, but here's some uber AU -
The Vampire Chronicles! (That's just my spur-of-the-moment name for them all, but they aren't actually related.)
It all started when smidgy06 wrote Afraid of the Dark (R) and Turned (14). Both contain Vamp!Michael/Vamp!Lincoln and are slashy, especially Turned. Note: Afraid of the Dark could technically be a crossover as well, because it features Angelus from BtVS.
After reading these, two fics were spawned, one by me and the other by miss_mandy. Mine was mostly a joke after thelana mentioned wanting to see a Sucre/Sara story (she didn't mean a vampire one). It is untitled and is found only in a comment to thelana's thread. Um, I guess it's PG-13. Non-graphic violence and, oh yeah, character death. miss_mandy wrote First Drink (PG-13), which contains T-Bag/Michael/LJ. It's another slashy one. Fun stuff! :)
