A role-play my friend and I are doing. It's my birthday "party favor," I guess. Enjoy! Remember, I will be holding a fanfic birthday party for myself and havarti2 and whoever wants to come is invited!

During the battle of Hogwarts, Alexandria became desperate to help Harry Potter and the Wizarding World. She went to the only person she knew could help...The Doctor. [11th doctor/Harry Potter/OC Crossover!]

The Doctor has gotten himself into a bit of a mess, and now he's a kid again. Shortly after de-aging however, a mysterious owl brings him a letter. He's been accepted to Hogwarts! But why? The answers lie behind the mysterious walls of Hogwarts, follow the Doctor as he unravels the mysteries of the school, and tries to fix the mess he landed in. Adopted from Bibliomaniac.

There is a woman who sits on a bench in London, knitting. She has always been there, even before there was a London. She is the Doctor's one confidant, though he knows not her name. She is so much more than meets the eye. She is Elizabeth Granger, Hermione's twin, thought to be dead, but simply hidden. This is her story. Love, loss, friendship, magic, and family. Maybe some danger.

When the TARDIS goes astray, the Doctor ends up at Hogwarts among Harry Potter, Albus Dumbledore, and many Hogwarts staff and students, past and present. How did they get there and how will they leave? The Doctor and Hogwarts.

What if Hermione was also visited by a certain Doctor throughout her childhood? How will their relationship progress as she grows up? Harry Potter/Doctor Who crossover.

Drabble. Strange middle grounds. Written for the Prompt Relay Challenge.

The Doctor encounters the hidden world of magic for the first time when the TARDIS lands in Hogsmeade. Both the Dumbledores are welcoming, but the Ministry makes life difficult. So the Doctor decides to get a wand of his own and the adventure really begins.

Draco Malfoy jumps off a bridge, hoping for death but getting something very different. Harry Potter languishes in a loveless marriage and colorless world, until quite abruptly he does not. From the dark places of the universe, there is a song that echoes everywhere and nowhere. It sings of power and it sings of hunger. It will devour all things before the end. Multiple crossovers.

Hermione Granger is returning to Hogwarts for her seventh and final year. And with returning, she promises herself that she will stay out of trouble; no more meddling. But all of that changes when a sassy red-head and a loud, energetic man become teachers at Hermione's beloved school. Will the witch ever have a safe year at Hogwarts School of Witchcraft and Wizardry?

Misadventures with the students at Hogwarts as the Doctor's daughter joins them as a fellow student.

Features Doctor Harry! story will be a short chapter format but more chapters per week like 2-3 chapters. So enjoy! " I might be a boy Harry thought but these memories of my Grandfather hes long dead turned into a human using the chameleon arch. But I have his memories now and the universe still needs a doctor.. its not done with him yet"

Against all odds, Voldemort discovers the existence of Time Lords and decides that he wants their secrets for himself. How far will he go, and will the Doctor be able to stop him? And, more importantly, what effect will this have on the wizarding world?

He won the war but lost his world...then he met a boy with the same problem.

A boggart and a Doctor Who fan do not mix well...

A Crossover that comes from the deepest parts of my mind. Crossover: Doctor Who & Harry Potter, I hope you enjoy and as always I do not own anything. Warning: Evil Dumbledore, Weasley Bashing, Good Voldemort and Abusive Dursleys (Unfortunately)

A tale in which a new Dark Lord comes to Hogwarts. Stomaggedon Dark Lord of All goes to Hogwarts.

A destiny that has yet to be fulfiled has come into play. A traveler and the lost girl always finding each other, one give hope another gives love. Can these two finally be free of there loneliness or will they foever walk the universe alone. [ 9th, 10th, 11th doctor/fem/harry]

My first legit attempt at a fanfic. Hope to be a great crossover of Harry Potter and Doctor Who. I wrote this because i felt there were not enough, so enjoy and please review. Rated M for possible death, violence, ect. (used more as a buffer zone for me really intended to be more of a "T", just wanted to be safe), not intending lemons or anything like that.

Hermione is wandering London, not sure what to do with herself, when she hears a strange wheezing noise. She follows the sound and meets the Doctor, who is looking for Clara Oswald, an impossible girl who's died twice. Hermione agrees to help him look for her as long as he gets her back before her exams, forming an unlikely friendship with another Hogwarts student along the way.

Harry's Boggart goes a little differently.

During a Quidditch match against Gryffindor, Cedric Diggory is struck by lightning. Waking up, he finds himself in the ship of a young woman, a ship that's bigger on the inside. His life will never be normal again. Crossover story with many other franchises. Prequel to "An Impossible Change."

The Doctor introduces Harry to the TARDIS and keeps a promise to a friend. Second in the Adventures of the Littlest Time Lord series!

The Doctor never thought he would feel that horrible, gut-clenching fear and fury again, but that's what comes with loving someone. Even with the potential for horrible pain, he wouldn't have traded Rose for the world. Despite the danger involved in loving him back, neither would Rose.

After Journey's End, 10.5 sent Rose back to the full blood when Pete's World faced destruction. She picked up four children from an alter-verse along the way...and fell short of her target. While younger Rose spends a week with her mum after Father's Day, her first Doctor has his hands full with elder Rose and her new friends.
