Summary: Doctor Who/Harry Potter crossover: The Tenth Doctor and Donna fly through a crack in the walls of the universe and land in a world where humans can perform magic. Getting mixed up in the cold war between the Death Eaters, the Ministry of Magic, and the Order of the Phoenix, all sides want the Doctor dead!
Author's Note: This story is a crossover between Doctor Who and the Harry Potter universe.
Harry Potter: This happens during the summer after the events of Harry Potter and the Goblet of Fire. Plot/events and character personalities are from the novel and not the movie, though character physical descriptions are more or less from the movie and not the novel.
Doctor Who: This is sometime in series 4, after Donna has had a few adventures with the Doctor, but before "Midnight" and "Turn Left."
Slightly non-canonical, because this story assumes that the Harry Potter books do not exist in the Doctor Who universe, which explicitly goes against the episode "The Shakespeare Code."
Donna picked herself up off the grating that served as the floor of the console room as the time rotor ground to a halt. “Blimey, that was rough! You’re getting worse at piloting this thing!” As she swept her red hair out of her face, the Doctor’s concerned look stopped her whinging tirade cold.
The Doctor was hopping around the console, twisting dials and flipping switches. “‘Sall right. Calm down there!” he soothed the TARDIS, patting the metal struts tenderly. He stopped at the monitor and peered at it, his forehead crinkled in concentration, one eyebrow arched.
Donna dusted off her maroon pantsuit as she watched the Doctor with unease. “What? What happened?”
Still staring at screen, the Doctor straightened up and ran both hands through his hair, stopping with his elbows framing his head like antlers. “Can’t be. But I can see it, too.” He was obviously still talking to the TARDIS. He backed away from the console, his mind racing, elbows still up in the air.
Donna’s yell could bring a dead elephant back to life, and it snapped the Doctor out of his train of thought. “Blimey! I never get used to that.” He smiled sunnily at her and turned back to the console.
“What’s wrong? Where are we?” She rounded the console to have a look at the screen. While she only had a basic understanding of how the screen worked, as a lot of the readout was in untranslated Gallifreyan, this time it was completely incomprehensible. She’d never seen the display in that layout, and none of it was in English.
The Doctor was again concentrating, but this time on manipulating the console readout. He typed, slowly turned some knobs, and flipped some switches while staring fixedly at the screen. Symbols flashed and mutated. “I… don’t know… We’ve left… the universe…”
“Left the what?”
“The universe, Donna. We’re somewhere else.” He fiddled with a few more controls before stepping back. “Yup. The TARDIS confirms it.” He turned to face her, an excited grin stretching from ear to ear. “You’re in a whole new universe, Donna Noble!”
“A crack in the walls of the dimension, probably. TARDIS flew right through it. As soon as we landed here, I could see it. The timestream is completely different. Disorientating, it is, having a new timestream running through your head. Like putting on specs with the wrong prescription.”
“But we can go back, right, Doctor?”
“Of course! Well, most likely. Well, when the TARDIS finds the crack again. She’ll take us right home.” Donna looked dubious. “But come on! A new universe! Don’t you want to see what’s outside that door?”
Donna looked at the wooden doors that led out. “You’ve never been here before? Could be dangerous.”
“Could be wonderful! And you’d be the first human to ever see it!” His enthusiasm was infectious, and Donna began to walk towards the door, curious but guarded, the Doctor behind her. “A realm where the sky is purple and filled with moons. A planet of sentient hatbands. A universe of tiny blue one-eyed creatures with wings.” Donna grasped door handle and pulled. “A world like you’ve never imagined before.”
“Otherwise known as London.” She stepped outside onto cool pavement and stood with her hands on her hips.
“Again?” The Doctor stuck his head out of the door and looked around, then up at the sky, the tip of his tongue pressed to the roof of his mouth. “No zeppelins this time.”
Donna turned to look at him. “You been here before?”
“Nope. Not this not-London.” She detected a hint of disappointment in his voice. “Why is it always London?” He retreated back into the police box.
Donna paused to take a look at the city again. She wasn’t familiar with the neighborhood they landed in, but she could see enough landmarks over the rooftops to recognize the city. No purple skies or flying blue critters. Just London. Stepping back into the TARDIS, she latched the door and leaned against it.
“Same old town. Sorry to disappoint. What are we doing, then?”
The Doctor was busy at the console screen once again. “Well, the TARDIS is going to take some time finding the crack. Been through it, so she can trace back, but it’ll take some time to calculate the coordinates and trajectory.” He looked up at Donna. “A couple of days, maybe more. But we’ll get back home.” He smiled reassuringly.
“And in the meantime?”
“Tourists! See the sights! It’s never the ‘same old town’ in a new universe! Oh, and shopping!” Grinning impishly, he punched one last button on the console, then strode for the door, snatching his overcoat from the support strut and slipping into it.
“Shopping!” repeated Donna, grinning. “Now that’s more like it!” She hooked her arm on his elbow, and they strode out of the blue doors together.
Donna never did get to spend much time just enjoying the places she visited with the Doctor. More often than not, they got embroiled in some life-or-death situation, then jumped back into the TARDIS in search of the next disaster. She was happy to have a nice day exploring this alternate London - and she wasn’t convinced this wasn’t her own London, as she certainly didn’t see a single difference - and the Doctor was a fine companion. She had never seen him smile so much. Taking in the sights, hitting the stores, dinner in a lively pub, and even a show. That was her definition of a fine day.
For his own part, the Doctor had a splendid day as well. Donna was his best mate, and they were wandering, without a care in the world - literally. Meeting new people, watching them as they went about their lives, marveling at the wonders that were human beings: it always exhilarated him. The unfamiliar timestream nagged at the back of his mind, but every universe flowed in its own unique way and as he got used to it, it felt less and less uncomfortable. As they wandered, he kept an eye out for differences between his home universe and this one, and there were a few. First, a newspaper established that the date was August in 1996, though culture - music, fashions, popular technology, etc. - were more in line with mid-2000s. He spotted some small differences in the buildings and streets of this London. The prime minister was a different person, neither Harriet Jones nor, thankfully, Harold Saxon, but someone he’d never heard of. Small differences, nothing that made him uneasy, and he threw himself into the task of enjoying the relaxation.
He did notice that not once did Donna even think about searching for her family and friends - or herself - in this universe. She was grounded, pragmatic, and above all, brilliant. He couldn’t help but grin with pride at the thought.
As Donna and the Doctor left the pub and headed for the show, a small, round-faced man, in a ratty, stained coat, watched them with beady eyes. Muttering to himself, he pulled a stick of wood out of his pocket and, holding it tightly in his gloved hand, turned on his heel and vanished.
