I'm only going to write a disclaimer once, at the start of this story. The fact that it's going on a FANfiction website should give it away, but I'll say it now. I am neither JK Rowling or Stan Lee (although I kinda wish I was Stan Lee). I own none of the characters of the Marvel Cinematic Universe(s), and I don't own Harry Potter either.

-.-Chapter 1-.-

A whirling storm, all around him. Colours flashing across his eyes. The howling of the wind. The crack of thunder, and the burst of lightning. He fell to the floor with a thud, unconscious.

A second figure fell from the sky, landing in the middle of the storm on his feet. He staggered drunkenly forwards, before –

The minivan slammed into him, throwing him to the floor. Three people stepped out, an old man and two young women. One of them checked his pulse, declaring him alive. Then, when he opened his eyes and lunged forward aggressively, the other shot him with a Taser, knocking him out.

As they re-entered the minivan, something caught the old man's eye. "Over there." He pointed. "Is that ..." He squinted, looking more closely. "There's another body over there!"

One of the women drove the minivan closer, and the old man dragged the second body into the van, after declaring him to still be alive. As the man took the wheel, the women looked at the two unconscious men. One had long blonde hair and a closely-trimmed beard, and a distinguished look about him. The other had black hair, and wore glasses. One of the women brushed his hair back, to see a scar on his forehead in the shape of a lightning bolt.

-.-.-

Harry Potter was familiar with the sensation of waking up from unconsciousness in a hospital bed, having done so fairly regularly throughout his school days. He was unfamiliar, however, with the sensation of waking up with restraints around his wrists and ankles.

He groaned, and the noise alerted the doctor in the room. "Ah, you're awake." The doctor said, looking at the chart at the foot of the bed.

"Where am I?" Harry asked.

"You're in hospital. You were found last night in a storm, along with another man. You didn't have any identification on you, just a pair of glasses and clothes."

"Yes, I do rather need them. If you'd release me, I'd like to be able to see properly again." Harry was lying, he'd had his vision corrected shortly after defeating Voldemort, and the glasses were simple glass frames instead of prescription lenses. The doctor didn't know that, though.

"The glasses are clear glass, sir. Why do you need them?" Apparently, the doctor did know that.

"Sentimentality." Harry said, throwing him a charming grin. "I needed glasses throughout my childhood, and when I had laser surgery, I had them replaced with clear lenses. Everyone knew me for having glasses, and without them no-one really recognised me."

"I'm sorry sir, we'll need a few details about yourself first before we release you. Your companion didn't have any identification either, and he attacked the staff when he awoke."

Harry frowned. "My companion? Could you describe him to me?"

The doctor nodded. "He was tall, about six feet. Dark blond hair, beard. Grey eyes."

Harry shook his head. He didn't recognise the description. "I don't know him. What details did you need from me?"

"Your name didn't appear on any of our servers, so we're going to need some proof of identity."

Harry thought for a second, before answering. "My name is Daniel Merlin." It was his established codename, a fake identity he'd had set up for undercover work with the Aurors. He didn't trust what was going on here, as things had been strange since he'd been taken by that portal. He certainly didn't want his real name going on record.

The doctor nodded, and began typing at a computer. He frowned. "There is no such identity on record. Do you have a contact number?"

"0800 00 62442. That's the number of my workplace." It was the number of the Auror Department, surely Dennis or Ron would be working and answer.

The doctor walked over to the landline on the wall, and dialled in the number. He stood for a minute, before hanging up the phone and walking back to the table. "That number doesn't exist. Who are you, really?"

Harry's eyes widened in shock. If the Auror Department number – which was magically enhanced, so it could be connected from anywhere on the planet – couldn't be reached ... where was he? Harry was so distracted by his thoughts, he didn't notice the needle until it pierced his skin.

"It's just a sedative." He faintly heard the doctor say, as he slipped into unconsciousness.

-.-.-

Harry woke up, dizzy and confused. He was handcuffed to a chair, in a dark and empty room. There was one more chair, and a desk separating him from it. On the desk was a folder, labelled MERLIN.

Looking around, Harry saw a man standing by the desk. He was fairly unremarkable, average height, with short brown hair. There was an earpiece in one ear, and Harry could see the outline of a gun holstered underneath his jacket.

"What's going on?" Harry asked, knowing full well what was going on. He just wanted to see if this man – an Agent Coulson, according to his ID badge – was going to be honest.

"Two men fell from the sky three days ago. One of them has since broken out of the hospital, and then broken into a top-secret facility, before revealing himself to be the Norse god Thor. The other is sitting in front of me."

Harry smirked. "So, you think I'm what? Some sort of alien? Or a god?"

"Are you?" Coulson asked, a similar smirk on his face.

"No, I'm not. Look, something strange is going on here." Harry decided to be honest. "I don't even know where I am, but I suspect that this isn't the world I'm familiar with."

"So you are an alien? If this isn't the planet you're familiar with." Coulson asked, a crafty smile on his face.

"No." Harry replied. "I think ... I might be in an alternate universe. My real name is Harry Potter, and I'm a wizard."

Coulson laughed. "Of course you are, Mr Potter." He then gestured to the folder. "Or is it Mr Merlin? That sounds more wizardly to me."

Harry shook his head. "Daniel Merlin is one of my aliases back home, I usually use it for undercover work."

Coulson slammed a hand on the desk. "So you are a spy! Who are you working for?"

Harry swore. This was clearly going nowhere. So he focused on the folder on the desk, and it began to levitate, startling Coulson, who drew his gun, aiming it at Harry.

"What are you doing?" He demanded.

"Wandless magic, Agent Coulson." Harry answered. "And this is nothing compared to what I could do, if you continue to hold me here. I want to talk to your boss." Harry was bluffing, of course. He'd learned wandless magic after defeating Voldemort, from Aberforth Dumbledore. It was a nice parlour trick, but nothing more. Levitating light objects, like paper or fabric, was possible. Anything else, like throwing fireballs or lightning from his fingertips, was not. That sort of thing was impossible without a magical focus. Coulson didn't know that, though.

Coulson stood up, and walked out of the room.

-.-.-

It wasn't too long before Coulson returned, accompanied by a tall black man. He was bald, with a neatly-trimmed goatee. But his most distinguishing feature was the eyepatch covering his left eye.

Harry leant back in his chair. "So you're the boss, I assume?"

"I ask the questions here." The unfamiliar man responded. "What are you?"

"I'll tell you what I am if you tell me who you are." Harry responded.

The man smiled maliciously. "I'm Nick Fury, Director of S.H.I.E.L.D."

Harry frowned. As an Auror, he knew most of the secret organisations across the world. He'd never heard of SHIELD, which made his alternate universe theory seem more believable. "Nice to meet you, Nick. I'm Harry. I'd shake your hand, but ..." He gestured to the handcuffs.

"Your freedom rests on whether or not we see you as a threat, Mr Potter." Fury paced, keeping his eye fixed on Harry. Coulson was leaning against the wall next to the door, also watching Harry.

"I'm no threat to you, Mr Fury. If you'd let me go, I need to return to where I was found, and then I'll quite happily disappear." It was a fair offer.

"Coulson tells me you fancy yourself a magician. Prove it." Fury demanded.

Harry simply smirked. "Of course, Mr Fury." He focused on Coulson's tie, and tugged it forward wandlessly. Coulson stumbled after it, and Fury chuckled.

"Not bad, Potter." Fury commented. "Why are you here, and what do you want?"

Harry sighed. "Can I be uncuffed first? I've been sat like this for quite a while, and it's getting uncomfortable."

Fury nodded, and Coulson unlocked the handcuffs. Harry rubbed his wrists, before resting his hands on the desk.

"You ask interesting questions, Fury. I've been wondering about them myself." Harry could tell that Fury wasn't the sort of man to put up with bullshit, so decided to tell the truth. "My name is Harry Potter, and I'm a wizard. I suspect I'm from an alternate reality, where magic is real, and there are more wizards around than just me. I'm twenty years old, born on July the thirty-first. My job is an Auror, which is the wizarding equivalent to a policeman."

Fury nodded. "Okay. Mr Potter, I'd like to offer you a job, of sorts. SHIELD will set up an identity for you, and in return, when we call on you, you will answer."

"What job?" Harry asked, curious. "And how come you believe me?"

Fury chuckled menacingly. "When you've been around as long as I have, you can tell when someone's being honest with you." Fury placed a file in front of Harry. "Have you ever heard of the Avengers Initiative?"

-.-End Chapter 1-.-

AN: So, Harry's been thrown straight into the deep end here, with interrogations from the two most awesome guys in the Marvel movies! The events of Thor have played out just the same, as have the events of Hulk, Iron Man, Captain America and Iron Man 2. Avengers will play out differently, though, with a wizard on the team.
