A BEAM OF BLUE LIGHT SHOOTS UP to the sky. Up in the air, a large portal slowly gets bigger as the galaxy above gets more evident. As it widens, swarming of chariots come down to the atmosphere.

The Chitauri.

Mini sets of missiles fly out of Tony's suit, causing mass explosions from mere contact. The first act of the invasion has now been set. The signs of each explosion representing a new challenge and obstacle the Earth has now been faced.

Civillians' eyes shoot up, the panic and adrenaline now kicking in as screams of franticness occur. Chitauri leaving destruction to roads, streets and even buildings.

Cars flipping over as civillians run away from the dangers.

Loki walks out the Stark tower's balcony. A grin appearing on his lips at the sight before him. The screams giving him a sense of satisfactory as the fire seems to literally brighten his day. 

Just then, Thor lands. Eyeing up his brother as he glares at him.

"Loki!" Thor shouts, grabbing the trickster's attention. "Turn off the Tesseract, or I'll destroy it!" Thor taunted, in a challenging tone. Although his brother merely smirks at him.

"You can't." replied Loki. He points his scepter at the favored brother. "There is no stopping it. There is only... the war!"

Thor shrugged.

"So be it."

Loki screamed at the top of his lungs as he menacingly jumps down at Thor. He attempts an attack with his scepter but the God of Thunder dodges. As Loki's feet are set on the ground, Thor swings his hammer, but blocked by Loki's staff. Another swing, this time by Loki's scepter, but Thor merely ducked down. Both weapons block each other's attack, causing a small wave of energy to disperse.

"Stark, we're on your three. headed northeast." Romanoff announced as everyone's comms went off.

"What? Did you stop for drive-through?" Tony sarcastically replied. "Swing up Park. I'm going to lay them out for you."

As he said that, a trail of chitauri follow in pursuit of the flying red soaring figure. 

--

AS THEY SEE TONY PASS BY they drop the gun of the jet, rapidly firing at the trail. The jet wobbling as Y/N tries his best to hold on.

They soar up, going up to the Stark tower. 

They look to their left to see Loki and Thor, battling out as the two as guardians fight it out. 

"Nat?"

"I see him."

They turn the jet, now facing the two gods. Loki grits his teeth as he throws Thor down, glaring at the soaring vehicle above him. He points his scepter, the blast of blue light emitting as it hits the left wing. An explosion instantly occurring as they slowly drop altitude.

The jet shakes, losing control.

"Ah! Shit!" Y/N screams out as the Jet drops. Both him and Steve hold on to the bars ontop of them as they brace.

But then, Y/N loses his grip, bumping as he floats around the dropping jet. He winces in pain as he hits a part of the jet. Possibly causing a bruise.

They find a space to land, dropping hard as the ground breaks due to impact. Broken pieces of concrete flying everywhere as now Y/N drops to his stomach, groaning.

As the jet stops, Steve pulls Y/N up.

"You alright?" He asks, receiving a nod as Y/N stretches.

"Atleast we landed.."

Nat and Clint remove their seatbelts, quickly getting up as the backdoor opens, revealing the mass destruction now in a different perspective. They make their way to the middle of the road as their thoughts are now filled with a possible outcome.

"We got to get back up there!" Steve said, pointing up to the tower just infront of them. Suddenly, a loud sound echoed. Not a growl but quite similar. Like a large boat, honking. They stop at their tracks as a shadow grows larger. 

A loud roar coming from the air, as a leviathan makes it's way down. 

"Holy shit...." Y/N mumbled as the large creature slowly descended. He turned to Nat as he stammered. "W-W-- That's what were up against?"

Nat is also at a loss for words, speechless. Her mouth open and closes in attempt to find something to say.

Y/N sighed. "I need a break after this.." He muttered to himself as he lifted his katanas out, gripping onto the handle tightly.

The creature flies above their heads as the group's eyes unconsciously follow it in awe.

"Stark, are you seeing this?" The comms went off. 

Just then, The Iron man figure soars as it follows the large leviathan. "Seeing. Still working on believing." He answered. "Wheres Banner? Has he shown up yet?"

"Banner?" Steve's eyebrows furrowed.

"Just keep me posted." He flew by the side of the leviathan as he continued to inspect. "Jarvis, find me a soft spot."

The group of four run over to a nearby taxi cab, taking cover.

"We've got civilians stilled trapped up here."

Then, a group of chitauri fire as the road below summons a trail of more explosions. Cars flipping over as people's screams increase at a higher rate.

"They're fish in a barrel down there." Steve panted out, inspecting the damage. As the words escaped his mouth, a shot was attempted but missed. 

In instinct, Y/N and Nat quickly get up, firing their guns at the source of the shot.

"We got this. It's good. Go." Nat reassured Rogers who reluctantly nodded. 

"Do you think you can hold them off?" Steve asked as Barton turned around, smirking. "Captain, It would be my genuine pleasure." Barton replied, instantly firing an arrow.

"Alright." Steve grunted out as he stood up, looking at Y/N who also gets up. "Don't get into too much trouble."

Y/N scoffed.

"How can I when you're taking all the trouble with you.."

Steve tensed as he looked over his shoulder. Y/N noticing Cap's body language, which earns a raise of an eyebrow.

Steve brushed It off as he ran, Y/N still in confusion until Nat snaps him out.

"Are you just gonna stand there, or what!?" She exclaimed, continuing to fire at more chitauri. Y/N was still in his confused state but shrugged it off as he helped out.

--

Y/N GUIDED PEOPLE AS THEY EXITED THE BUS, making sure to lead them to safety. He then was handed with a crying baby. Slowly holding him as he rocked him while the father of the baby was busy dropping down.

Y/N stared at the baby, slowly rocking him. The baby somehow was quick to give it's trust which shocked Y/N. The baby's tears were no longer escaping it's eyes as he stopped sobbing.

He was snapped out of his thoughts when the father got him out of his hands, making sure to thank Y/N.

Before Y/N assisted, he looked around to see if anyone saw it. He was surprised to see Nat who quickly looked away as their eyes landed at eachother. Continuing to round up some shots.

"Hey! Help me out with this!" Clint's voice was heard. Y/N turned his head to the direction of the voice, leading to a Clint Barton struggling to open the door.

Y/N quickly ran over there, easily opening it as more civilians run away from the disaster occurring. 

He quickly got back to the cab, helping Nat and now a Clint who joined in.

"Just like Budapest all over again!" Nat shouted over from the loud shots. Y/N and Clint raise an eyebrow at the redhead.

"You and I remember Budapest very differently." Clint and Y/N said in unison. Just then, a loud bang was heard from not too far. Y/N head snapped towards the sound. A big dance of fire swirling in the air from a building not too far. Distant screaming was heard.

"Hey, Clint." Y/N called the archer who hummed. "Give me cover, I'm gonna get them somewhere safer."

"Are you su--"

"Yes." Y/N quickly cutted off. "Yes, I'm sure."

Clint looked over at him in worry before slowly nodding. Y/N patted his back before making his way.

--

THE CIVILLIANS VOICES WERE OVERLAPPING as they were all brought to a small area, all in one room. Above them were chitauri, aiming below as the adrenaline started to rush before them.

A growl echoing through each direction they look. A chitauri placed on each place they want to move.

Just then, A chitauri suddenly shot a blast, startling people. They look up to see that the same chitauri, dropped down to the ground below. Lifeless. Another started another blast, same thing happens. Just then, a dark figure slides through the window, barely dodging another blast.

He kicks the table over, causing the tribe member to stumble which he uses advantage. He jumps up before landing a punch as he descends down.

Another Chitauri grips him from behind as he grunted from the tight grip. A tribe member infront of him, aiming his blaster. As the shot leaves out of the weapon, Y/N flips over, causing the blast to hit his fellow member. 

He flips back up and throwing his katanna right through the heart.

As he thinks his on the clear, another explosion occurs, leading him to fly out the window as he crashed down to a car. He groaned in pain as he landed on his stomach.

"Ergh!-- I really hope that was fucking worth it.." Y/N grumbled.

--

AS CLINT WAS TACKLED, the chitauri was sent flying. He looked over to see Y/N, limping over with his gun pointed.

Just then, Cap came back, helping out the three as they continued their fight on the ground. Lightning was then summoned, making the job easier as Thor landed.

"What's the story upstairs?"

As Cap and Thor talked, Y/N limp walked over to Nat who was on the ground. He placed his hand out, bending down a little bit. Nat stared at him for a bit. Her panting slowly decreasing as she accepts the hand. 

Y/N pulls her up, they looked at each other. Before Nat could walk away, she felt a tight grip on her arm.

"You alright?" Nat nodded in response. Y/N looked at her face, slowly brushing a strand of her hair. She furrowed her eyebrows in confusion as Y/N looked at her. 

Before Nat could respond, he was already with the rest.

What was that all about?

"...The cube is impenetrable." Thor continued. 

"Thor's right. We got to deal with these guys." 

Their comms went off as the voice of Stark spoke up. Nat turned to Cap as she looked around the destruction around. "How do we do this?"

"As a team."

"I have unfinished business with Loki."

Clint scoffed. "Yeah? Well, get in line." He remarked, causing Y/N to shake his head.

"Save it." Cap says. "Loki's going to keep this fight focused on us, and that's what we need. Without him, these things could run wild. We got Stark up top. He's going to need us to--"

He was interrupted when the sound of an engine revving was heard. Cap slowly turned to see, Banner. 

They all walked up to him, Y/N's eyebrows furrowing in confusion as he looked over the man. Banner slowly gets down from the vehicle, his arms out.

"So, this all seems horrible." He pointed out.

"We've seen worse." Y/N and Nat said simultaneously. Y/N's eyes narrowing behind his mask.

Steve gave Y/N a look of sympathy.

"Sorry for.... wacking you earlier.."

Y/N shook his head as he waved it off. "Nah-- We actually need a little more... wacking...?" He said in a mixture of question but was received by an elbow to the ribs by Nat. 

"Stark, we got him."

"Banner?"

"Just like you said."

"Then tell him to suit up." Tony started. "I'm bringing the party to you." Just as the words left his mouth, Tony's figure was seen soaring as a Leviathan crashes a piece of a building from the sharp turn. 

Y/N's eyes widening.

"I-I don't see how that's a party."

The Leviathan was heading forward as it was supposed to be led. Banner turned to the rest, before walking over to the large creature. Y/N's head tilting in confusion.

"Uh-- Bruce, man." Y/N called out. "Now might be a really good time for you to get angry."

Bruce turned around, smirking.

"Thats my secret, Y/N." He started. "I'm always angry."

Hulk landed his right fist on the coming Leviathan, the momentum causing it to flip over as it crashed down. "Hang on." Stark said, firing missiles out of his arm as it hit the Leviathan. In impact, the Leviathan blew into pieces as fire combusted. Causing them to take cover.

They all formed a circle. Hulk roared in challenge, Clint prepared an arrow as he aimed, Thor flipped his hammer before gripping it tightly, Nat loaded a clip on her piston, Y/N swung his sword repeatedly, Iron Man descended down as Steve slid the shield on his arm. 

Ladies and Gentlemen. The Avengers.

"Theres too many of them.." Y/N mumbled as more Leviathans and Chitauri descent. Everyone looking up as it slowly made its way through the atmosphere.

"Call it, Captain."

"Alright, listen up." Steve called out. "Until we can close that portal, our priority is containment."

Barton, I want you on that roof. Eyes on everything. Call out patterns and strays. 

Stark, you got the perimeter. Anything gets more than three blocks out, you turn it back or turn it to ash.

"Can you give me a lift?"

"Right." Tony walked up to Barton, holding gripped at his back. "Better clench up, Legolas." As he said that, they lifted up in the air.

Thor, you got to try and bottleneck that portal. Slow them down. You got the lightning. Light the bastards up.

You, Y/N and me stay here on the ground. We keep the fighting here. 

Cap turned to Hulk.

And Hulk--

Wack!

Cap and Nat turned to Y/N, raising an eyebrow. Y/N licked his lips nervously.

"I mean-- Smash!" Y/N corrected earning a grin from the Hulk. He jumped up high in the air, Immediately doing his job.

--

AS NAT WAS PINNED BY A CHITAURI, it was sent flying as Y/N kicked it away. He grabbed the small staff, firing it at an incoming tribe member. He was about to fire another until he realized it was just Cap.

He panted, placing his hand on his waist.

"Cap, no offense." Y/N pointed out. "This won't mean anything if we don't close that portal."

"Our biggest guns couldn't touch it.."

"Well, maybe its not about guns." Nat chipped in, looking up.

"If you really want to get up there, you're going to need a ride." Steve pointed out, earning a shrug from Nat. She started making her way to the opposite direction before a tight grip was felt on her arm. She looked over at Y/N, raising an eyebrow.

"What?"

Y/N sighed slowly looking at her. 

"Did I ever do something wrong to you?" Y/N suddenly let out. Nat tilting her head. Y/N nervously looked around. "Look-- uhm-- When all of this is over-- Whatever I did to you... I hope I can make it up."

Nat's eyebrows furrowed as she stared at Y/N. She slowly nodded, pulling her arm away as she turned back around.

"I-I could use a boost." She mumbled, loud enough for Steve to hear. She took one last place for Y/N, He gave a small salute. Her lips curled to a small smile.

Steve took a step back holding his shield.

"Are you sure about this?"

"Yeah." Nat hesitantly let out. "Yeah. It's gonna be fun." She then runs towards a car, jumping from it. Using it's momentum to land on Cap's shield. Cap then boosts her up, timing the jump as she takes grip on one of the chariots.

--

Y/N DODGES AN ATTACK before sweeping the member on the floor, knocking it out with a punch. Loud stomps could be heard in his ears as he swiftly turns around and blocking it's attacks.

The Chitauri attempts to swing at Y/N using it's staff. Y/N grips on it as he uses most of his strength to turn the staff around. He knocks the Chitauri member with a kick before shooting one last blast with the staff.

"Hm, alien tech is pretty cool.."

[Static]

"L/N, Civillians." Steve spoke up.

Oh right.

He was supposed to be on civilian duty.

"On it."

As he jogs his way through the road, he immediately takes cover as a group of Chitauri come in to his sights. He takes a pistol out, shooting one at a time before taking cover. As he takes out at least five, he comes out of the wall.

His eyes widening. 

Groups of Chitauri more than he expected.

His first instinct.

Stupidly enough, take each of them down.

As he sprints towards them, he knocks sweeps an incoming Chitauri. One comes at him swinging. He uses his two katanas to block it. In the corner of his eye, another incoming Chitauri. He uses the distraction of blocking as a clear path to send a roundhouse kick, knocking it down.

Once he was on his two feet, a swarm was running towards him. Another comes at him, his left hand gripping the staff as he used the other to impale them with his katana. He uses the staff to blast some Chitauri. Due to his lack of focus from behind, he was knocked down from a kick.

He landed on his stomach.

As he attempts to get up, One kicks him. Then Two..

Then Too many...

Things were starting to go downhill..

--

SOUNDS OF GROANS COULD BE HEARD from their comms as Steve takes out another. His eyebrows furrowing. 

"L/N? Is that you?" Steve places his his two fingers on the comm, but to no response. "L/N, do you copy--"

He was cut off when a shot was blasted onto his stomach. Only a flesh wound. But he winced in pain.

Things were starting to go downhill..

--

AS TONY LANDED a shot square in the chest hit him, knocking him to his feet as Chitauri do their best to corner him, aiming their weapons.

Things were starting to go downhill..

--

CLINT NOTICED A SWARM of Chitauri. As he reached for an arrow, there was none left. He used one from earlier, pressing a button that unlocks the zip line feature. He quickly jumped out the rooftop, barely dodging an explosion as he shot the arrow.  The hook attaching to the building as he used the momentum to swing inside a floor, glasses shattering open as he winced in pain.

Things were starting to go downhill..

--

ANOTHER SWARM OF CHITAURI surrounded Hulk. He roared in frustation.

They all sent rapid shots at the green giant, the blasts were too many, you couldn't even see the giant.

Things were starting to go downhill...

"Director Fury is no longer in command, override Order-7-Alpha-11."

"7-Alpha-11, Confirmed. We're ready for takeoff."

"Stark, you hear me!?" Comms went off, Fury's voice. "We have a missile headed straight to the city."

"How long?"

"Three minutes."

--

NATASHA PIERCED THE SCEPTER but quickly stopped her pushing as she sent a warning. "I can close it." She grunted out. "Can anybody copy? I can shut the portal down!"

"Do it!"

"No wait!" Tony cut off.

"Stark, these things are still coming!"

"I got a nuke coming in." Tony explained as he soared over the blue waters. "It's gonna blow in less than a minute.... And I know just where to put it.."

Everyone was intrigued as they heard the words come out of Tony's mouth. This was a good plan and all, but the risk factors were high.

Tony hovers under the missile, grabbing onto it as he used his strength to lead it.

"Stark, you know that's a one way trip.."

Tony completely ignored it.

"Save the rest for the turn, J."

"Sir." JARVIS' voice came out. "Shall I try Miss Potts?"

Tony thought about it. He really did. Underneath, he was gritting his teeth, clenching his jaw. This was a sacrifice. A sacrifice he was willing to take.

"Might as well.."

Everyone watched.

Edge of their seats.

Their breathing suddenly quickened as they watched the scene.

Thrusters came out of Tony's suit..

The momentum carrying the missile to shoot up. as it takes a sharp turn..

His figure going higher and higher until he was no longer in sights..

He was now inside the portal.

People cheering and sighing in relief..

As Tony slowly lets go of the missile, his life flashes before him. He watches at the nuke rises slowly to his destined direction. As it impacts with the Mothership, a huge blow occurring as he slowly descends.

Swarms of Chitauri now shutting down..

The Avengers look around their surroundings as one by one, they fall down. The relief shooting up to their core as they can stand there, breath.

 A Leviathan crashing down as it takes a hard hit.

Tony slowly closes his eyes as he descends back to earth. 

"Come on, Stark..."

Steve looks at Thor. A look of mutual agreement. There was no choice.

"Close it.."

Nat sighs, hesitantly pushing it the scepter through the crown. Grunting as she uses all her strength to get it in.

The beam of light now shutting away as the wormhole closes.

They wait...

They wait....

A small smile appears as the figure of Stark comes back. But panic starts to rise as he continues to go down, losing more and more altitude. Worry is a keyword.

"He is not slowing down.." Thor swings his hammer, in preparation. Before he can make a move, Hulk comes out of nowhere, tackling Tony's descending body as he glides down using a skyscraper as guide.

Relief...

Hulk touches down the ground, GENTLY placing Stark flat on his back. Thor and Cap frantically sprints over their direction, checking on him. Thor takes away a piece of his helmet, throwing it away as they look at Tony's lifeless face.

Cap places an ear to Tony's mouth.

Hardly any breathing.

He can't do CPR. The metal surrounding him blocking any more procedures.

Hopeless...

They all stare down Stark's body, guilt is definitely a term through these current events. 

Denial...

Hulk roars at the top of his lungs.

Startling, Tony.

"AH!-- huh-- What the hell..." He lets out, heavily panting as he looks up. "What just happened? Please tell me nobody kissed me."

Cap sighs in relief and in amusement.

"We won.." 

Cap then looks around the area, his eyebrows furrowing. So does Thor. 

"Where is L/N?" Thor questions as he frantically looks around. No signs. "Maybe-- er-- use your comm-- thing." He pointed as Cap nodded in agreement.

"L/N, This is Rogers. Do you copy?"

static

Cap looks at Thor, worry starting to come back. Thor shrugs, not knowing what to do.

"L/N... This is Rogers, Please ans-- Do you copy?"

"Guys..." A feminine voice called out. They all looked at the direction of where it came from. It was Nat. 

Their eyes widening at the sight.

Nat was holding on to two swords, both broken to a half. To make things worse, his mask on her other hand.

"L/N is.... missing..?" Nat questions, denial kicking in. They all looked down, clenching their jaw in realization as Nat shook her head. "No..."

Steve shook his head.

"We lost a soldier...."

"L/N is down."

FURY COLLAPSED ON HIS CHAIR as Hill quickly caught him, carefully placing him back. His lips quivering as tears start to swell up. Something he hasn't done in a while. He placed both hand on his eyes as Maria placed a hand on his back, in comfort.

"That son of a bitch really did it."

--

[A/N: Changing up the last scene]

--

THEY WERE ALL GATHERED AROUND AS A CLOSED CASKET DESCENDED. The body was not found, which made things worse. They wanted to at least se his body for one last time.

They all dressed in black attire.

Everyone came.

Stark, Rogers, Odinson, Barton, Hill, Banner, Fury and Romanoff. They have already sent Loki to Asgard few days prior. As the day came, the entire mood shifted. It was down, moody.

The setting was a bit dark, small droplets dropping down as the sky was gloomy. A perfect setting for a sad occasion. 

One by one, they sent their respects.

Stark threw in a flower.

Rogers threw in a flower.

Thor threw in a flower.

Clint threw in a flower.

Hill threw in a flower.

Banner threw in a flower.

Romanoff slowly threw in a flower.

And Fury......

Since the Director was a figure to Y/N, he was last. He slowly walked up to the descending casket. A picture and a flower on his hand. 

The picture showed a young Y/N, being held up by Fury. Smiles appearing on both of them, a fun memory. 

He threw both the flower and the picture at the same time.

His lips pursing

As time flew by, each Avengers patted Nick on the back as he knelt down at the stone Infront of him.

HERE LIES Y/N L/N

1984-2012

Matthew 11:28

'Come to me... I will give you rest."

As everyone was no longer in sight, Nick pressed two fingers at his comm. 

"Enjoy retirement, You son of a bitch.."

A chuckle came to the other side of the line.

"Thank you, Uncle Nick."

AS THE CEMETERY WAS EMPTY the sounds of grass being stomped. We look up at the figure. Heels, Black dress, Red hair. Romanoff slowly stood infront of the tomb stone, kneeling infront of it. She rubbed it slowly as her lips started to quiver. 

Guilt...

She sniffed in a tear as she spoke. "I'm sorry, you weren't able to make it up to me." She whispered, rubbing the stone. "I'm sorry, I was an asshole to you." She continued to rub it. "And I'm sorry, for not being the person-- [sigh] the person--" She trailed off. She was not able to speak. She looked down, a tear appearing on her eye..

Y/N's eyes were in a sign of awe as he observed from the distance.

(A/N:YOU THOUGHT WE WERE DONE?)

Post Credits Scene:

--

THE SOUND OF TAPPING OF A MIC echoed through a lab. 

"Hello, Ladies and Gentlemen. Welcome!"

"You all wonderful people are gathered here to witness something Revolutionary! New world order coming through its way!" The man exclaimed through his mic. Judging by tone alone, we could tell, he is a bit mad, psychotic maybe. "As threats have now breathed in our earth's air, we would like to take this opportunity to come out of the shadows.."

A pair of boots walking through the halls.

"We live in a society where people are separated, disintegrated even. People who couldn't fit in will now have a chance to release their potential!" He gripped tighter on the mic as he grinned. "Chaos. It's better to live in a world of equal chaos rather than living In a world of unequal equality. Deep down...We are all Monsters!"

A guard came unto him, whispering into his ear as he nods, waving the guard off.

"Ladies and gentlemen... he is here..."

A grin appearing.

"Project: Mirrocc is in full affect."

The doors burst open, a figure being revealed earning applause. One by one people stand up. The Number 'eight' on their uniforms as they cheered. 

The mad man grinned as he watched his creation standing..

This is a welcome to a new arc.

--

A/N: THERE GOES ACT ONE LADIES AND GENTLEMEN

Now here is a brief explanation of what will be happening. Don't be afraid to ask questions down below while at it.

So the next arc is a solo arc.

This next arc will be (AND IM HOPING) way better than act one. This is due to the fact that now I have my own creative freedom. As you are currently reading this, I am forming a plot.

Promises I can give - This will be one of the most emotionally driven arcs.

Go ahead and give some suggestions and I will see you next act!
