Matt Smith has just finished filming the first half of season seven in Doctor Who and can't wait to spend some time with his family; however, destiny has other plans. As he's driving home, Matt runs into (literally) a man who looks exactly like him and claims to be the Doctor. Loosely, I'll follow season 5. I'm counting Matt as OC because he obviously isn't on the character list.

Harry's first year is over and now Vernon is sending him to a Great Aunt he has never heard about. But this kind woman sending Harry to her youngest son and his Partner. But its not all an easy road.

Everyone dies. That's what people do. But not me. Sherlock Holmes, consulting detective and unfortunate immortal. After waking up from my untimely death (which was meant to be fake) life has become far more complex. Now, to solve the ultimate mystery. Why me?

Mrs Hudson could never imagine that finding a small child in the back yard of 221 Baker Street. A little boy with no family, and her Boys doing the unexpected and opening their hearts to him, and their home.

Discovered by a maid named Martha Jones, Amy is invited to stay in the house of her employer, John Smith, until Amy finds her husband. But there's something strange about John.

I was normal, I promise. I didn't want this. I don't know what is happening. I promise, it wasn't supposed to be like this, I'm human. I can't be...

Four psychiatrists and twelve years after arriving onto a stranger's doorstep, John Smith has been diagnosed with multiple-personality disorders, psychosis and schizophrenia. However, Vastra believes John is much more than he seems and offers him a place in her prestigious and mysterious school for unusual and talented adolescents. (mutants/superpowers AU)

A bit of Johnlock au drabble, following the pair from childhood to their old age.

It wasn't John's fault. Not at all. And Sherlock didn't blame him. The man couldn't possibly understand. He couldn't know what bringing the red-haired puppy to Bakers Street would do to the detective. He couldn't understand what Redbeard's death all those years ago had put in motion. That dog's death was how it all began.

They always said that Sherlock wasn't normal, wasn't quite human. Well, what if they were right? What if Sherlock was actually a regen of the Doctor? Will contain a bit of Whouffle and Johnlock for all you shippers out there. (:

What if one morning the Doctor and Sherlock Holmes wake up and realize they've switched bodies? Can they stop the switch from continuing to happen? How does this affect their friends? Now they must travel across universes to find each other and set things right.

Alyss and Scarlett Little grew up as witches, homeschooled by their father in the muggle world. When disaster strikes, they go to Hogwarts, where they find their footing, new friends, new enemies and, on Alyss's part, a little bit of confusion, because she meets this guy, and nothing seems normal.

Sherlock, who is muggle-born, is completely out of place at Hogwarts. That all changes, however, when he befriends John Watson, a third-year beater on the Griffindor Quidditch team. A time goes by the pair get closer and closer. And it all began with a funny little letter... Johnlock AU Sherlock/Harry Potter crossover

David Tennant has long been considered to be a fan favorite who went on to become a more accomplished actor in the outside world. But what if that never happened? What if after his stint as the 10th Doctor, it all dried up? Now facing a grim reality, David finds himself at a deadly crossroads…that is, until the real 11th Doctor appears… (DW: Season 5/ AU/David Tennant/ 11th Doctor)

[Set: pre-"Rose" Ninth Doctor, post-"The Crystal Cave" pre-"The Coming of Arthur"] All seems well when the TARDIS takes a wrong turn and ends us in the Middle Ages; Camelot is exactly the new adventure he's been looking for. However, a mysterious blue box appearing out of nowhere causes trouble, and soon local historical figure Merlin is dragged into an unforgettable escapade.

Johnlock AU where Sherlock and John are attending Hogwarts School of Witchcraft and Wizardry (post battle of Hogwarts) quite a bit of parallelism with BBC's Sherlock

"Now I have the revenge I've always desired." Morgan murmured, a sly smile resting in the curve of her crimson lips. "They will never find their way back. Every person who ever stood against me, I stole their memories, their identities, and threw them into an unknown,frightening place." The servant looked up. "Where's that, M'lady?" "The twenty-first century."

What if Pete Tyler never came back to save Rose? What if she fell into the void, but survived in a sort of comatose state because she was protected by the power of the Bad Wolf? People fall out of the rift sometimes, and they can end up any where. What if Rose fell out of the rift—and was found by Captain Jack Harkness? Eleven/Rose (Rated T for extremely mild language!)

[One-Shot] Basically, three Doctors are stuck together in a room with a big threatening button that must not be pressed under any circumstances. Good Luck.

After not seeing him for decades, the Doctor finally shows up at Sherlock's flat - with a different face. He has come because he is in need of Sherlock and John's help. His friend has been kidnapped by the Winchester brothers during a huge misunderstanding. Will the trio be able to make it in time before something bad can happen?

The door peeked open, and out stepped a young man John had never seen before. He reminded him of someone, with his pale skin, high cheekbones, and dark hair… Even if it was straight instead of curly behind his oversized ears and his eyes were a darker blue than he was used to... Sherlock gave a weak smile at John's shocked expression. "John, meet my little brother, Merlin Holmes."
