Harry Potter and the Mad Man with a Box

Chapter 1: The Return

"Pathetic Potter, is that really the best you have?"

Panting, Harry stared up into the coal black eyes of his Occlumency instructor: Severus Snape. The man sneered in disgust as the son of his childhood tormentor spat onto the floor. Grunting, the teen pushed himself to his feet, grimacing as his t-shirt clung horribly to his torso with sweat. Snape glowered at the boy and pointed his wand between Harry's emerald green eyes.

"Now, again."

"No."

"Legi-What did you say?" He snarled, lowering his wand arm slowly, glaring at the teen's look of defiance.

"I said, no. Sir."

"How dare you, you insolent brat!"

"Insolent! All you tell me is 'clear your mind', without actually telling me how!"

"Then you are as weak as I-"

"The only weak one here is you!"

"How dare you, you do not know what I must do in order to keep ungrateful brats like you safe-" Harry snorted, cutting the older male's tirade short.

"Like it's Dumbledore you obey, we all know who you really serve."

"You think you know everything Potter, you're just like your father: arrogantly believing that you know everything."

"For Merlin's sake, my father is DEAD! Get that through your greasy head you overgrown bat. How pathetic are you that you blame the sins of the father on the son, no wonder they picked on you, you greasy git."

"I WILL NOT BE SPOKEN TO LIKE THAT YOU BASTARD CHILD!" Snape screeched, whipping his wand in Harry's direction. Only Harry was faster.

"EXPELLIARMUS!"

A bolt of scarlet energy shot from the tip of his wand and slammed into the black-clad man, sending his wand spinning towards Harry while Snape was blasted across his office. Catching the black wand in his left hand, the last Potter stared at the crumpled form of his Potions/Occlumency professor and gulped slightly.

"Please dear Merlin, let him have hit his head." He muttered, placing the other wand on the shelf next to him and quickly making his way back to Gryffindor tower.

"Oh man, if Hermione finds out about this she's gonna kill me." He groaned as he made his way up a flight of stairs. He knew that she would find out, she was the only one who was able to squeeze the truth from him, no matter what the subject was.

"So close..."

He stopped abruptly, swinging his head around in search of another person.

"Hello?" he called "Is anyone there?" When only silence reached his ears, he shrugged and began walking again.

"The time is near, it must be opened." Jarring to a halt, he whipped his head round to stare along the corridor.

"Peeves, if it's you cut it out! If you're trying to irritate me at least attempt to make sense."

When there was no response, he nodded to himself in satisfaction and continued on his way to his dorm. However, as he made his way up past the fourth floor, what felt like a bolt of lightning flashed across his brain. Harry fell to his knees as his mind's eye was plagued with snippets of memories.

None of which were his.

Men in silver, shrieks of "EXTERMINATE", faces of people he had never met and a blue box swirled around his mind as he sunk to his knees in pain.

"You know where it is, the time has come: time for our return."

"Shut up!" He roared as he gripped the sides of his head. And just like that, the voice and the images vanished.

Panting slightly, he shakily resumed his journey back to Gryffindor tower.

'How can this get any worse?'

"Harry James Potter, what do you mean that you 'kinda' blasted one of our professors across the room!"

'Well bugger, this was what I was afraid of.'

He raised his hands in a placating manner as he stared into the irate brown eyes of his best friend.

"Mione, calm down. To be fair, he drew his wand on me first."

"That doesn't matter Harry, you attacked a BLOODY teacher! And-where are you going?"

Harry had begun to walk up the stairs of the boy's dormitory, the muggleborn witch followed after the teen, growling.

When she caught up with him, he was digging through his trunk like a man possessed.

"Harry, Harry what are you doing?"

Instead of answering, the raven-haired teen simply kept digging for a few minutes before letting out a cry of "Aha!" and straightening himself up. Clutched in his left hand, was something silver. Hermione approached her best friend in concern as he sunk unto his four-poster bed, staring at the object in silence.

"Harry? Harry are you ok?"

The last Potter turned to the bushy-haired young woman and frowned at her.

"The watch, it was calling to me." Hermione's eyes widened.

"You mean it was talking to you? Harry, you should probably give that to Professor Dumbledore to-"

"NO!" Harry yelled, startling the girl at the volume of his yell. Thank Merlin no one else was in the dorm at the moment.

"Sorry, it's just, I know this watch. And yet, I've never touched it until now."

They sat in silence for a few minutes, staring at the watch in curiosity (Harry) and wariness (Hermione). After five minutes, Harry spoke up.

"It wants me to open it, says the time is right." Hermione stared at him incredulously.

"Please tell me you're not going to do as it says. It's obviously dangerous."

Getting to his feet, Harry continued to stare at the watch for a few more seconds before looking over at the worried face of his best friend.

"I need to Mione, it feels right. Whatever is in here, I need it." Turning to look at the watch in his hand, he started as he felt a smaller hand grip his wrist. He looked over at the witch to his left and was surprised to see a tear make its way down her cheek. "Mione-"

"Harry, please." Her voice was small as more tears began to leak down her cheeks "I don't know why but, if you open that watch. I feel as though you won't be you. That watch, it's changing the way you act now and I fear" she hiccupped slightly as she released the hold she had on his arm. "I fear I'll lose my best friend."

Harry looked to his friend, 'No, my ONLY best friend.' He thought, in shock.

"Hermione, I-I had no idea you felt that way. It's just," He turned his head to stare back at the battered watch in his palm, "I have to. Listen-" he began, stopping the bushy-haired girl's interruption, "I know it seems mental but please, trust me. Trust me Hermione as I know that whatever is in this watch, it is good and it will help explain so much of what is going on. Please Mione, trust me."

The two stared at each other, the intensity of their gaze filling the room as the watch continued to emanate warmth.

"I trust you, Harry." With a small smile, the green-eyed wizard tugged the brown-eyed witch into a tight embrace, releasing her a few minutes later.

"Thank you, my Mione."

And with that, he released the latch of watch.

Instantly, he was bathed in golden-orange energy that surged out of the watch. Images of other worlds, strange creatures and a blue box filled his mind. He watched as different faces filled his mind; an old man wearing a skull cap, a younger man with a recorder, another with shaggy white hair in a yellow car, one with a long scarf, a young man with a stick of celery, a loud man with a multicoloured coat, an old man with an umbrella, a young man in Edwardian garb, an old man staring sadly at a large red button, a brooding man in leather, a skinny man in a brown suit, another young man with a fez and an old man staring at his reflection in a mirror.

Hermione watched in horror as her best friend's body began to change. He grew several inches and his body began to fill out, his hair growing longer as his glasses fell from his nose. Hand over her mouth; she stared as the fiery energy was absorbed back into her friend's skin. Stumbling slightly, he doubled over in order to catch his breath. Warily, she approached the raven haired male.

"H-Harry?" His head shot up to look her in the eyes as he straightened up.

"Lungs!" He gasped, slamming his hands into his chest "My lungs are weird!"

She stared at him as his hands roamed his own chest, a look of awe in his eyes. "New lungs, oh! Heads, shoulders, knees, toes, arms, hands and fingers!"

Each body part was briefly touched as he listed them of, when he stopped suddenly. His hands went to his hair, scrunching his eyes shut.

"Please be black, please be black." He tugged down a lock and opened his eyes.

"Yes! Not been black haired in a while. Not since my second body..."

"HARRY!" He stopped his discovery of his new form in order to look at the terrified girl staring at him. He smiled as he skipped over to her.

"Hermione! You're smaller, wait a sec, that's not right. Am I taller? Oh deeper voice too, oh that's very nice. Hermione, Hermione, Hermione, HHHHHeeeeerrrrrrrmmmiiiiiooooonnneeeeee."

"What happened to you, why are you acting so oddly?"

"Only 'oddly'? My dear, I'm insulted! I don't do odd." Staring around at his surroundings, he was confused due to disorientation only for a frown to mar his features.

"Oh! This is bad, very, very bad."

"What's bad?" asked Hermione, her eyes wide as she watched what used to be her friend pace the dormitory "Harry, your scaring me."

Glancing at the girl, 'Harry' smiled before resuming his pacing.

"What's bad is that we're in a parallel universe. I can taste it. Timelines are all wonky here, things that shouldn't be but are..."

"You're not making sense! Now, tell me what happened to my friend or I swear I will hex you to oblivion!"

"Hex-" He began, only to find himself on the business end of Hermione's vinewood wand. A manic grin blossomed across his lips.

"Oh that is brilliant, no, beyond brilliant! Its, its..." he frowned slightly before clapping his hands loudly, the grin back in full force, "Its wicked! Yeah, that's the word, wicked." Still grinning like an idiot, he tossed off his robe and untucked his shirt.

"That's better, now! Miss Granger, I'm happy to tell you that yes: I'm still Harry Potter. Just...more than just Harry. You see, that watch" he pointed to the battered fob watch that now lay on the floor between them "contained my essence, waiting for the right time to 'wake up'."

"So who are you then? If you're more than 'just Harry', who else are you?" 'Harry' grinned at her again, stuffing his hands into his trouser pockets.

"Well Hermione Granger: I'm the Doctor."

AN: And cut! Well? What do you guys think? Yes, I know that, compared to my last two uploads, this is quite a short chapter but this is my first attempt at a DW fic, even if I'm pretty comfortable with HP. I didn't want to rush in the TARDIS, monsters and general bad-assery so; I leave it up to you. I'm going to leave a poll up on whether or not this will expand from a one-shot to a multi-chap fic. I do know that I have enough material for at least three or four chapters but that will be up to you lot. If made into a multi-chap, each part being released on a Saturday along with the new episode. If not, well I still think its decent. Anyway, make sure to review, as I would love to hear your opinions. This is AuraStormMaster, signing off.
