AN: This is my new Avengers Story. I am going to do it several chapters in between my Doctor Who series to give my self a break, I hope you like it. I think it's going to end up being about 7 or 8 chapters and I am aiming for each chapter to be about 4500 words (hopefully).

This I going to be Clint/OC story (Look at the second chapter of my Character Profile story for more information).

If I miss anything spelling or grammar wise please let me know as its not my strong point so I will probably make many mistakes and I don't have a beta.

The Actress I picture to play my OC is Eliza Dushku.

Any outfit for my OC described are on my Tumblr and Polyvore which you can access through my profile page.

Can I just say as well I from the UK so some of my spelling might be different from what it's supposed to be for the film.

I have not seen Thor, Captain America or Iron Man 3, all the information I've put in this is from the first two Iron Man and Avengers film as well as anything I look up online.

~*8*~ is a scene break

Italics is a Thoughts and foreign languages

Disclaimer: I do not own the Avengers, or anything that is recognised. I only own my OC and her back story. I got the parts of the script I kept through subtitle on the DVD so I don't own them either.

Director Nick Fury and Agent Maria Hill, both wearing their regular SHIELD uniform and weapons, where approaching a SHIELD research facility in a black army grade helicopter. They where accompanied by Agent Alana Clancy, who was wearing a pair of grey skinny cargo jeans, a black bomber jacket, military issue boot, and was also carrying two pistols strapped to her belt and a knife strapped to her thigh.

They look down at there destination to see red lights flashing as the alarm blares and the over head speaker which can be heard announce that the evacuation protocol had been put into effect. People are running around trying to gather their equipment and direct people to where they are supposed to go.

Landing quickly they meet Agent Coulson on the edge of the landing pad and start to hurry into the facility.

"How bad is it?" Fury demands.

"That's the problem, sir. We don't know" Coulson answers simply.

~*8*~

Coulson leads them through the facility and down an elevator, getting off at the right floor and heading toward the direction of the stairs that lead down to the testing room Coulson says "Dr. Selvig read an energy surge from the Tesseract four hour ago"

"NASA didn't authorize Selvig to test phase" Fury says to Coulson as they walk, Hill walking directly behind listening in on them while Alana keeps an eye on everything else going on around them out of habit.

"He wasn't testing it, he wasn't even in the room. Spontaneous event" Coulson says.

"It just turned itself on?" Hill butts in.

"What are the energy levels now?" Fury questions ignoring Hill.

"Climbing" Coulson states "When Selvig couldn't shut it down, we ordered the evac"

"How long to get everyone out?" Fury asks wanting to know the time frame.

"Campus should be clear in the next half hour" Coulson tells him.

"Do better" Nick demand over his shoulder as they lead off to do there separate jobs, not seeing the smile Coulson and Alana share.

~*8*~

"Sir, evacuation may be futile" Hill says as they head down some stairs.

"We should tell them to go back to sleep?" Alana cuts in a very sarcastic voice.

"If we can't control the Tesseract's energy, there may not be a minimum safe distance" Hill says adamantly appearing to ignore what Alana said.

"I need you to make sure that PHASE 2 prototypes are shipped out" Fury asks ignoring her.

"Sir, is that really a priority right now?" Hill asks sounding confused.

Fury finally turn to face her stopping on the stairs "Until such time as the world ends, we will act as though it intends to spin on. Clear out the tech below. Every piece of PHASE 2 on a truck and gone" he orders.

"Yes, sir" she says grudgingly before turning to the two standing agents "You two, with me"

~*8*~

Fury enters the lab facility where the Tesseract is being held, approaching the Doctor closest to the glowing blue cube, it seems to be pulsing slightly and flares of energy spike out in arcs at random intervals.

"Talk to me, doctor" he orders as Alana stands at ease behind him.

"Director" the doctor greets him as he walks around the machine holding the Tesseract.

"Is there anything we know for certain?" Fury asks.

"The Tesseract is misbehaving" the Doctor says seriously.

"Is that supposed to be funny?" Fury asks raising his one visible eyebrow.

"No, it's not funny at all. The Tesseract is not only active, she's...misbehaving" he says gesturing to the scientist that has just been shocked whilst poking the Tesseract with a metal stick

"How soon until you pull the plug?" Fury asks getting down to business.

"She's an energy source. If we turn off the power, she turns it back on. If she reaches peak level..." Selvig says trailing off.

"We've prepared for this, doctor. Harnessing energy from space" Fury starts.

"We don't have the harness. Our calculations are far from complete. Now she's throwing off interference, radiation. Nothing harmful, low levels of gamma radiation" Selvig interrupts.

"That can be harmful. Where's Barton?" Fury asks, making Alana perk up and actually listen for the answer.

"The Hawk? Up in his nest, as usual" was Selvig's reply making Alana smile slightly.

Agent Barton otherwise known as Hawk eye, dressed in his black tactical gear, is up on the railings watching them below, until Fury calls Barton on his earpiece "Agent Barton, report"

Barton rappels down from the catwalk and walks up to Fury and Alana. They walk around the facility, watching all the scientist in a discreet manner.

"I gave you this detail so you could keep a close eye on things" Fury says in an undertone.

"Well, I see better from a distance" Barton shrugs as he walks close to Alana taking her hand without anyone seeing.

Fury sighs far too used to that answer before asking "Are you seeing anything that might set this thing off?"

"No one's come or gone. It's oven is clean. No contacts, no I.M.'s. If there was any tampering, sir, it wasn't at this end" Barton answers letting go of her hand and crossing his arms.

"At this end?" Fury asks looking curious.

"Well yeah, the cube is a doorway to the other end of space, right? Doors open from both sides" Barton answers as if it should have been obvious.

"Is everything alright, Doctor?" Alana asks making both Fury and Barton look over to Selvig, watching as he types away quickly at the keyboard and sees on the monitor the Tesseract's energy spiking even worse than before.

Before he can answer there is a crack of energy and then another before suddenly there is an even louder crack like thunder as the Tesseract starts to shake violently causing the entire facility to shake with it. The energy flares, as everyone stops and stares at it. It continues to pulse and crackle, before it glows even brighter and then it seems to pop as the energy builds up before it morphs into a beam. The beam launches forward at least 30ft to a platform before swirling around creating a dome.

The beam then swirls until it eventually forms a sort of vortex big enough for a single person to fit through. Looking through the portal the blackness of space can be seen, strewn with a billion stars, only for a moment before it seems to almost implode in on itself sending a blast of energy out wards in a wide circle knocking people back a bit from the force but leaving them unharmed.

There was a moment where everything was dead silent before loud breathing could be heard from the platform. Everyone in the room looks over towards the platform, Alana pulls out one of her guns just in case.

A figure is kneeling on the platform, smoke coming off it. He is dressed mainly in black with green and gold panelling, and his face looks pale, a stark contrast to the black hair that goes to just above his shoulders. The figure raises his head and looks up, seeing the humans around the room he smiles and chuckles. He looks directly at Fury, Alana, Barton and Selvig, before standing up, holding what appears to be some kind of sceptre in his hand.

"Sir, please put down the spear!" Fury cautions.

Loki looks at his sceptre then suddenly points it at where Fury, Alana and Barton are standing firing a blast of what looks like the same energy the Tesseract.

Barton tackles Fury, both barely getting out of the line of fire as Alana throws herself to the side coming up from a roll before aiming her gun at Loki, firing along with several other agents but the bullets seem to just bounce off him.

Loki jumps from the platform and attacks those firing at him. In the space of several seconds, Loki manges to take down several guards with his knifes and his sceptre. He turns towards Alana as she keeps firing at him until her bullets run out dodging the blasts of energy he sends her way. He manages to get close to her just as she grabs her knife and grabs her around her neck, She raise her arm to stab him but he manages to grab her wrist restraining her before he smirks and throws her into the wall knocking her out.

Barton finally manages to stand up and engage after being thrown down from the backlash of one of the energy blasts, although he is favouring his leg. Loki quickly walks towards him. Barton raises his gun, but Loki just grabs Barton's hand and twists it to the side.

"You have heart" he says before pointing the sceptre at Barton's chest over his heart. The sceptre glows blue and seems to almost absorb into Barton in waves, the energy travels up his chest up to his eyes which turn black for a second before clearing, leaving behind what looks like a blue film covering his normally green eyes. Barton puts his gun away and stands straight up facing Loki like a soldier awaiting orders.

As Loki does the same thing with a couple more of SHIELD's personnel, Fury manages to make his way to the Tesseract and places it back inside a lead lined, bullet proof brief case before turning to leave the lab.

"Please don't. I still need that" Loki says in an almost polite tone.

Fury turns slightly towards him still keeping his back turned "This doesn't have to get any messier" he says looking around for an escape.

"Of course it does" Loki scoffs "I've come too far for anything else. I am Loki of Asgard, and I am burdened with glorious purpose" he introduces

"Loki? Brother of Thor?" Selvig looks up in recognition where he just managed to stand up leaning heavily on a near by table.

"We have no quarrel with your people" Fury interrupts seeing the look Loki shoot Selvig and not wanting anyone else to get hurt or killed.

"An ant has no quarrel with a boot" Loki answers focused again.

"You planning to step on us?" Nick says disbelievingly.

"I come with glad tidings, of a world made free" Loki says smiling a little crazily.

"Free from what?" Fury demands annoyed.

"Freedom" Loki says not noticing Fury's raised eyebrow "Freedom is life's great lie. Once you accept that, in your heart" Loki points the sceptre at Selvig and his eyes glaze over like the rest "You will know peace"

Fury releases an inaudible sigh "Yeah, you say peace, I kind of think you mean the other thing" not looking back as he feels the static charge building in the wide open space behind him.

Barton walks over and warns "Sir, Director Fury is stalling. This place is about to blow. Drop a hundred feet of rock on us. He means to bury us"

"Like The Pharaohs of Odin" Fury smirks not noticing the groan from where Alana lay as she starts to come around.

"He's right. The portal is collapsing in on itself. You got maybe two minutes before this goes critical" Selvig says as he check the reading coming up on the computer.

"Well, then..." Loki trails off looking at Barton who doesn't even hesitate and shoots Fury right in the chest knocking him backwards as the bullet hits is vest.

Loki leading them away gestures to Barton who grabs the case containing the Tesseract as they all leave the lab together, not noticing behind them Alana getting up and silently moving to Fury's side to make sure he's OK. Fury's nods at her before gesturing for her to follow them.

~*8*~

Alana follows them silently picking up a couple of guns along the way, as they head down to the sub level parking lot.

Seeing Hill, Barton says "Need these vehicles" gesturing to a car and a humvee.

Hill looks at him suspiciously "Who's that?" nodding her head to Loki.

"He didn't tell me" Barton replies as they all get into the cars Loki sitting in the open back of the humvee. Hill walks away still looking unsure just before they hear Fury speaking through the walkie talkie "Hill, do you copy?!" Fury grunts as the walkie crackles "Barton is turned"

Hill while not knowing exactly what is happening looks quickly over her shoulder before ducking and rolling behind cover as Barton fires his gun at her. Using the door as coverage Alana starts to fire on the cars along with Hill but Barton just gets into the drivers seat of the car and drives off.

Alana heads for another humvee shout for Hill to get in, before quickly driving after them. Hill quickly start firing her gun as they chase through the tunnel leading off the base.

Several SHIELD trucks pull up to them and start firing as they hear Fury through the talkies. Loki, who is standing on top of the bed of the truck, uses his sceptre and fires another energy blast flipping over SHIELD trucks. Alana quickly swerves down a side tunnel to avoid the collision before speeding up. They join the main Tunnel just in front of Barton and Alana spins the car before they both start firing on them shooting through the wind shield to try and get a better shot.

Barton's presses his foot down and speeds up which causes Alana Jeep to wobble and spin off back behind Barton. She loses control for a second before regaining it and giving chase again. The tunnel starts to fall down around them causing them to have to focus on dodging that then stopping Barton and Loki.

With one final blast wave of the Tesseract's energy the tunnel starts to cave in, the large chunks of rock start falling knocking into the side of Alana's Jeep and causing her to spin slightly before even more rocks fall down in front of them and cut them off nearly trapping them in, there is a gap at the entry way to the tunnel just big enough for a small person to fit through and both agents run to get out just as the rest of the tunnel caves in. They can only watch on as Barton's truck drives of into the desert landscape.

~*8*~

Fury's helicopter flies over Barton's truck and Loki looks up. From the chopper's door, as it slides open and Fury stands there holding a gun and shooting at Barton. Loki looks at Fury and fires his sceptre at the chopper. Just before the chopper crashes Fury jumps out just missing the car and lands on the desert floor.

Fury shakes himself off then starts to fire at the Loki again but they are out of range. Over the talkies Coulson is trying to get through to him "Director? Director Fury, do you copy?"

"The Tesseract is with the hostile force. I have men down. Hill?" He asks waiting for a reply.

"A lot of men still under, don't know how many survivors. Me and Clancy are nearing your location sir" Hill answers as she and Alana pick up the pace to get to him quicker.

As they approach Fury immediately starts to give out orders to Hill "Sound the general call. I want every living soul not working rescue looking for that briefcase"

"Coulson, you pick up Clancy and get back to base. This is a Level 7. As of right now, we are at war" he says into the talkie.

Coulson replies "Will do" he pauses before speaking again "What do we do?" Fury doesn't answer for a moment he just stands there thinking. He gets a look of determination on his face before he nods to himself "I'll tell you when we get there" he says softly looking over at the remains of the research facility.

~*8*~

On the outskirts of Russia near a rail road, there was the sounds of fighting coming from inside the construction building. Agent Natasha Romanov was tied to a chair being beaten by one of the Russian thugs surrounding her. The thug back hands her one more time before the leader of the group walks forward saying in Russian "This is not how I wanted the evening to go"

"I know how you wanted this evening to go. Believe me, this is better" replies Natasha also in Russian.

"Tell me, who are you working for, Lermentov, yes?" the man called Luchkov questions "Does he think we have to go through him to move our cargo" he drawled as one of the thugs rock her backwards in her chair, balancing her off the edge of an open floor.

"I thought General Soholob was in charge of the export business" Natasha questions in a fearful voice.

"Soholob? A bag man, a front. Your outdated information betrays you. The famous Black Widow and she turns out to be simply another pretty face" drawls Luchkov.

"You really think I'm pretty?" Natasha says coyly.

"Tell Lermentov we don't need him to move the tanks. Tell him he is out. Well..." Luchkov says as he slowly walks over to a table filled with a variety of different, he lets his hand wander over them before stopping and picking up a pair of pliers "...you may have to write it down."

One of the thugs grab Natasha's jaw digging hi thumb into the joint forcing her mouth wide open.

Suddenly, one of the thugs cell phone rings. Looking confused, he answers.

"Ya?" He answers before looking towards Luchkov "It's for her" he says handing him the phone.

"You listen carefully..." Luchkov says angrily only to be interrupted.

Alana's on the phone "You're at 1 – 14 Silensky Plaza, 3rd Floor. We have an F-22 exactly 8 miles out. Put the woman on the phone or I will blow up the block before you can make it to the lobby"

Luchkov looks slightly worried before he places the cell phone against Natasha's ear where she traps it between her ear and shoulder.

"We need you to come in, Nat" Alana says sounding tired.

"Are you kidding? I'm working!" Natasha says sounding thoroughly confused.

"This takes precedence" Alana says.

"I'm in the middle of an interrogation and this moron is giving me everything" Natasha states.

Luchkov say "I don't give everything" before falling silent when Natasha sends him a look.

"Look, you can't pull me out of this right now" she says determined to finish her mission.

"Nat. Clints's been compromised"

Natasha pauses for a second letting that information sink in before deciding "Let me put you on hold" She nods to Luchkov.

As Luchkov comes to take the phone off her, Natasha kicks him in the groin then as he jolts forward she head buts him knocking him to the ground. She stands up as much as she can whilst still tied to the chair kicking the thug that comes straight at her, using the chair as a weapon she hits the second thug before rolling with it and taking out the third by running him backwards before jamming the chair leg down on his feet and slamming her head backwards breaking his nose. Using the chair as leverage she spins tripping up another thug before using him as a springboard and flipping up over him and smashing the chair down on the back of the first thug. The last thug tries to grab her from behind but she twist his arm and hits him hard in the ribs with the piece of the chair still tied to her arms before kicking off him into a floor flip jumping up, running at the last thug standing, running up him wrapping her thighs around his head and flipping him knocking him out against the floor. She then walks over to Luchkov as he is trying to get up wraps a chain tightly around his ankle before throwing him down into the open floor, suspending him in mid air.

Natasha goes over and picks up the phone "Where's Barton now?" she says to Alana who through it all had been waiting patiently.

"We don't know" she answers with a sigh.

"But he's alive" Natasha says optimistically.

"We think so. Coulson will brief you on everything when you get back. But first, we need you to talk to the big guy" Alana assures.

"Doesn't Coulson know that Stark trusts me about as far as he can throw me" Natasha says smugly.

"Yes, that's why I've got Stark. You get the big guy" Alana says mock-cheerfully.

"Bozhe moi" Natasha cursed as she walks out the building hanging up the phone.

Bruce Banner follows a little girl into a shack on the far edges of the city Calcutta in India. Once inside the shack the little girl run straight to the back and escapes out the back window.

"Should have got paid up front, Banner" Banner says sardonically to himself.

Natasha then appears from behind the curtains. Banner turns around, quietly to face her.

"You know, for a man who's supposed to be avoiding stress, you picked a hell of a place to settle" she says.

"Avoiding stress isn't the secret" Banner replies still on edge.

"Then, what is it? Yoga?" Natasha replies trying to lighten the mood.

"You brought me to the edge of the city, smart. I uh... assume the whole place is surrounded?" Banner says gesturing around the room.

"Just you and me" Natasha says as convincingly as she can.

"And your actress buddy, is she a spy too? Do they start that young?" Banners says in disbelief.

"I did" Natasha shrugs

"Who are you?" Banner questions

"Natasha Romanoff" Natasha answers politely

"Are you here to kill me, Miss Romanoff? Because that's not gonna work out for everyone" Banner says sadly.

"No. No. Of course not. I'm here on behalf of SHIELD" Natasha says shaking her head.

"SHIELD" Banner says surprised "How did they find me?"

"We never lost you, doctor. We've kept our distance, even helped keep some other interested parties off your scent" Natasha explains.

"Why?" Banner questions not trusting her at all.

"Nick Fury seems to trust you. But now I need you to come in" Natasha says simply

"What if I said no?" Bruce questions although he expects he knows the answer.

"I'll persuade you" Natasha says simply.

"And what if the... other guy says no?" Banner asks looking around slightly nervous.

"You've been more than a year without an incident. I don't think you wanna break that streak" Natasha says shaking her head.

"Well, I don't every time get what I want" Banner states warningly.

Natasha decides to change tactics "Doctor, we're facing a potential global catastrophe" she says sitting down at the small table pulling out her phone.

"Well, those I actively try to avoid" he says knowing what she is trying to do.

"This is the Tesseract" she says sliding her phone over to Banner watching as he picks it up and takes a look "It has the potential energy to wipe out the planet"

"What does Fury want me to do? Swallow it?" Banner asks confused.

"Well, he wants you to find it. It's been taken. It omits a gamma signature that's too weak for us to trace. There's no one that knows gamma radiation like you do. If there was, that's where I'd be" Natasha says leaning back in her chair.

"So Fury isn't after the monster?" Banner asks still not believing her.

"Not that he's told me" she shrugs

"And he tells you everything?" he asks.

"Talk to Fury, he needs you on this" she says simply.

"He needs me in a cage?" demands Banner.

"No one's gonna put you in a..." Natasha start but was interrupted by Banner slamming his hands down on the table" STOP LYING TO ME!" he shouts getting an instant reaction of her reaching under the table for the pistol she placed there and aiming it at Banner.

Banner stands straight up, smiling almost smugly "I'm sorry, that was mean. I just wanted to see what you'd do. Why don't we do this the easy way, where you don't use that, and the other guy doesn't make a mess? Okay? Natasha..." Bruce says soothingly.

Natasha lovers her gun slightly reaching up for her ear piece and speaking into it "Stand down. We're good here"

Banner looks at Natasha with a raised eye brow before his mouth twists into a smirk "Just you and me?"

Nick Fury walks into an old fashioned boxing gym to meet Captain America AKA. Steve Rogers, he walks into the main room to see Rogers with his hands wrapped punching a bag clearly lost in his memories, he keeps punching the bag until he lands one solid hit and knocks the bag right off the chain, splitting it open and spilling sand everywhere. Steve opens his eyes then goes to pick up another bag to hook up when he hears someone behind him, tensing slightly before relaxing remembering he is not in the war any more and looks over to see Director Fury

Fury walks in and says "Trouble sleeping?

"I slept for seventy years, sir. I think I've had my fill" Steve comments off handedly.

"Then you should be out, celebrating, seeing the world" Fury says as Steve stops punching the bag and walks over to the bench, unravelling the tape off his hands.

He sits down on the bench saying "I went under, the world was at war, I wake up, they say we won. They didn't say what we lost"

"We've made some mistakes along the way. Some very recently" Fury admits.

"You here with a mission, sir?" Steve asks looking up.

"I am" Fury confirms.

"Trying to get me back in the world?" Steve says.

"Trying to save it" Fury corrects.

Fury hands Steve a file on Tesseract, along with an other folder.

"Hydra's secret weapon" Steve asks shocked

"Howard Stark fished that out of the ocean when he was looking for you. He thought what we think, the Tesseract could be the key to unlimited sustainable energy. That's something the world sorely needs" Fury explains.

"Who took it from you?" Steve asks going straight into soldier mode.

"He's called Loki. He's not from around here. There's a lot we'll have to bring you up to speed on if you're in. The world has gotten even stranger than you already know"

"At this point, I doubt anything would surprise me" Steve comments.

"Ten bucks says you're wrong. There's a debriefing package waiting for you back at your apartment" Nick says as Steve turns and picks up a punching bag before walking out of the gym.

"Is there anything you can tell us about the Tesseract that we ought to know now?" Nick asks as Steve passes him.

"You should have left it in the ocean" Steve says as he leaves the room.

AN: Hope you like it, please tell me what you think,

I'll have the next part up as soon as possible, Sarah x :)
