I've literally been obsessing over the Marvel MCU
So I came up with this.
As far as I intend, this fanfiction will go from the start of Avengers (2012) and continue throughout the MCU
So yeah. Much of this chapter is just backstory to show how all of this is actually relevant
I hope it makes sense? Idk, I'm tired and I have essays to write

Disclaimer: I don't own Naruto or the Marvel Cinematic Universe

Chapter 1: The Truth

"This is the tesseract that you were looking for…" The woman said with a soft tone. It glowed with beauty and seemed like nothing more than a glorified paperweight. The trouble she went through to get it was…admirable. "It doesn't seem powerful."

"Neither does this fruit." The man replied with the same tone. He saw that there were only a few bites left. Seeing the power the woman received from it, he wanted to try his hand, only to find the surface as hard as steel. "Why can't I bite it?"

"Same reason why I can't use the tesseract." The woman replied ambiguously. "My body…cannot make room for the power within."

With a quick motion, she tossed the glowing cube to the purple man sitting in his floating seat. He caught the cube all the while, returning the fruit. Pale white eyes met with eyes of red. A mutual understanding fell between the two. To think, a Titan and a Goddess meeting on slightly…civil terms. Taking a bite of the fruit, the woman quickly turned her back to the 'Mad Titan' as he was called by his foes.

"Thanos." She said. "We have a deal. I will use my powers to aid you in keeping Galactus away from your interests. But I would be sure that you keep your promise in staying away from my planet."

Thanos laid into his seat. "Kaguya…we've known of each other for many years and you don't trust me?"

"Of course I don't." The woman glared menacingly, the vertical Sharingan-Rinnegan hybrid on her forehead blaring with heat. "You're strong, I'll admit…but not even Asgardians and their mighty Odin will fight me. They know their place as should you."

"I understand…Kaguya." Thanos glared, clasping his hands beneath his furrowed chin. "You've grown more violent."

"It's no matter." The horned woman quickly turned on her heels, levitating off the stony steps. "My son's descendants will help me in containing Galactus. And you…get to continue your quest for the Infinity Stones you're constantly searching for."

"Go…" Thanos took a deep breath. "My Chitauri will escort you-"

"If any one of your slimy shits get anywhere near me…" Kaguya glared, flaring her chakra in all directions. "There'll be hell to pay. We aren't allies and we sure as hell aren't friends."

Thanos' chair rocked, tumbling against the rocks beneath him. Steps collapsed and even asteroids yards away began to crumble to dust. "What we have is an agreement; an agreement I will see come to fruition."

"Your change in demeanor is a threat to me in my domain." Thanos rose from his seat, voice bellowing like thunder. A tic mark formed when he realized that Kaguya hadn't once flinched. If anything, she seemed unapologetic and almost unimpressed. Through clenched teeth, the Titan spat. "What makes you think you can defeat me and my Chitauri army?"

"I have no doubts of my abilities to defeat you." She replied. "There are things on Earth that not even Galactus has seen."

With that, the woman eased her power. Thanos visibly eased, leaning into his seat. Suddenly, he felt a spike in power come from the woman. Anticipating an attack, five Chitauri drew their weapons in preparation. Kaguya was a terrifying woman when scorned. Space and time ripped open before the seated Titan. It was darker than night and filled with less than the void itself. She smirked at him, taking a step into the hole. Before she could fully disappear, she halted for just a moment to face him.

"My sons and I will destroy any and all opposition one day. We'll be the most powerful beings in the Galaxy." She said, the Sharingan-Rinnegan hybrid spinning like a whirlwind. "And if you ever think you can step foot on my home...I don't think I need to say what'll happen."

"Y-You don't understand!" Kaguya roared over the chaos of the battle. "I need this power! We need this power!"

"Mother, we understand perfectly!" Hagoromo roared back. "You want to protect us, but at what cost?! You've brought nothing but death and destruction to our home…!"

"Hagoromo is right!" Hamura replied sadly. "You promised peace…but you've only angered the gods!"

"There are no gods but me!" Kaguya shouted. "I have defended this world from what lies beyond for decades…and this is the thanks I'm given?!"

"We appreciate everything you've wanted to do and accomplished…" Hagoromo responded adamantly, staff in hand. "But what you're doing now is wrong!"

"Enough talking, brother!" Hamura shouted, stabbing his staff into the dirt. "We have to end this and finish the job mother started!"

"Fine…" The two sped through hand seals.

Kaguya held onto the grip she had on her tailed beast. "No! If you seal me and the Juubi away…you risk opening our home to the will of Thanos! Don't do it, please!"

"Mother…" Hagoromo bit his lip, still channeling his chakra. "I'm sorry…for peace to truly reign on Earth…"

"Chibaku Tensei!" The twins roared out, clapping their hands together, gathering all the chakra they could maintain. The earth cracked, spreading in all directions, letting the sea rush in like a tsunami. Earth split rising to the sky, meeting with the Juubi and Kaguya, merging and building around the two. The Juubi thrashed and bellowed, howling into the scarlet night. Its ten tails dug into the earth, splitting mountains and creating storms with each slash.

Kaguya's eyes widened for a moment when she realized the Juubi had shrunk, dwindling with power. She gritted her teeth, Byakugan eyes activated with rage. Her breath hitched when she realized that her most powerful technique was being used against her. She struggled against the gravitational pull, and couldn't even create a portal to escape from!

Struggling to bring her arms to form hand seals, she watched with horror as the Juubi, a great being of massive power and destruction was degraded to a bone-like statue, screaming like a bawling child. Its hands had grown chains, binding it to the stones of the Chibaku Tensei. It fought back, its nine eyes shutting painfully. It cried, begging for help, but Kaguya could offer no such help. Chains of chakra formed around her wrists, pulling her towards the epicenter of the technique.

"I can't believe my own sons won't see the truth…" Kaguya shed a single tear, leaning against the rocks and boulders, pressing against her body. "One day…they'll see I was right. They'll call my name begging me to help them…crying out for forgiveness…"

"I curse you, Hamura and Hagoromo…" Kaguya shed more tears, shutting her Byakugan eyes. "Your family lines will be cursed with death and destruction…you advocate peace as I did…you will bring death and pain…as I did…"

Now all she could hear was the rocks and boulders crashing against her already pressurized body. Tumbling and merging together with each passing second. Light slowly disappeared, cutting her view of her beloved home. Kaguya gulped. Air became thin and soon enough, her world grew colder by the second. Ice formed in the cracks of the boulders, gripping onto her like the very chains that bound her.

"Let time pass…and one day…" Kaguya frowned. "I'll find the perfect descendants to carry on my legacy…one day…Earth will no longer have to be afraid of the Universe…"

"She's gone?" The man asked, rising from his seat. "What do you mean she's gone?!"

"M-Master…" The sniveling being cowered. "H-Her signature has disappeared. We can't sense where she is or if she's even in the dimension...!"

"Who could do such a thing?" Thanos asked, completely flabbergasted. "What of her clones that she'd left on many planets? Where are they?"

"Collapsed or became wrapped in their cocoons once more…" The minion backed away when the giant Titan jumped down to his steps. His face bore a new expression, one the minion couldn't discern or comprehend. It was almost as if Thanos was worried…or worse; afraid. "Any assets that Kaguya had left for us…they're gone."

I have watched for centuries…

I have watched my sons destroy this world more than I ever had.

I am the monster?

I am the traitor?

I…am the one forgotten?

Who speaks of the name Kaguya anymore? Thanos even disappeared from my sight.

Those fools beyond the galaxy think I'm weak. They think my bloodline is weak.

They're not wrong.

They're not right.

I can't stay here and watch my home burn with Chakra that should have only been mine and mine alone.

They can't control the power of gods without wanting to become what they're not…

Only I can control it.

I am the only god.

My sons were fools.

My sons, sons were bigger fools.

Their sons and their sons, sons were the greatest fools

Now…chakra has been weaponized longer than the Juubi's own existence. How can they justify my imprisonment? How can I be left here…frozen in space; forgotten?

No.

Not anymore…

No longer will I wait…I must plan for my return.

Suddenly, chakra was born from her body once again, spreading from her arms. Before anything could be done though, the chains that bound her were awoken. She gritted her teeth for the first time in centuries. The chains glowed, absorbing her chakra, warming her arms and body. Skin thawed and sleeves finally rippled. She could sense that the seals etched into the chains had weakened.

Kaguya winced as a piece of her left. Almost like her soul had split. She growled, feeling her chakra flow for the first time. The seals were weak but she'd managed to force a sliver of her power free. It was as dark as night, bleeding like ooze. It had one white eye and no mouth. As far as she knew it was silent. And that was the exact thing she needed; a silent assassin. One that could endure pain of unbelievable measures; one that could bring forth her will.

That is what this was. She smirked; eyes shut but her Sharingan-Rinnegan eye spinning wildly. This being will be her will; her instrument to bring change. Too long she'd been complacent, frozen in cryogenic sleep. Time had been lost to her carelessness, but no longer. She will find the ones who will embrace her goals with open arms and protect Earth from the likes of Thanos and Galactus. Even from the Kree and Dark Elves, and if she wills it, the Celestials themselves.

She will be the true protector from the shadows. Kaguya thought to herself, smiling. Even if she had to paint herself as the enemy, the progenitor of destruction and chakra of its purest form; then so be it. From great peril, great heroes are born; that is a fact. And the fact is, the galaxy is in need of heroes; and she already had an idea of where to look.

Black Zetsu…go. I'm certain Thanos had realized by now, the tesseract I gave him was a cube I put a strong fuinjutsu over. If he attacks Asgard, he'll force too many things too soon. Sneak into Odin's treasure trove and take it. Make sure you ONLY take the tesseract and hide it. Instigate a war with the Dark Elves, instigate war between the Frost Giants. Kaguya smirked. The people of Earth are primitive right now…keep the Asgardian's eyes averted. Be unseen. Be quiet and most of all, be strong. Kill any and all who get in your way.

The eye on her forehead swiveled, turning to face the one eye of her child. Yes…mother…

"S-Sasuke…" Naruto was worried, orange eyes meeting with Sasuke's Sharingan-Rinnegan eyes.

"D-Don't make any sudden movements, Naruto…" Sasuke's reply was just as confused.

Kaguya held them, thumbs rubbing against their cheeks. She couldn't control herself. They're goals were etched into their eyes. She could see it even without the Byakugan. Her heart raced, staring at the two. Their goals were the same as hers. They were heads and tails and she was the coin. They were her. They were her sons. Tears welled in her eyes when she met theirs; seeing the fear they felt. Didn't they know that she was their mother?

Hagoromo…Hamura. She thought, tears burning against her cheeks. It's your mother…please! Remember me!

Naruto's expression softened greatly, immediately reminding her of Hagoromo. Sasuke retained his seriousness, reminding her of Hamura. They were Indra and Ashura. They were Madara and Hashirama. They were Naruto Uzumaki and Sasuke Uchiha.

And they were the ones to inherit her will. She smiled suddenly, pulling the two close to her. Their shared expression was of nothing but horror. No more than a silent whisper, she wished the two good luck. Kaguya hurled the pair back towards their teammates with enough strength to knock them all into oblivion. She smiled, sensing the future.

It seems Black Zetsu placed the tesseract on earth with foreigners. Kaguya shut her eyes. Foreigners that worship the Asgardians…this will work in my favor. For now…I must bring about my plans. Naruto, Sasuke. You have broken the curse I placed upon my sons. Now…fulfill your destiny and protect your home!

Chakra exploded from within her, shooting in all directions. Naruto, Sasuke and their two teammates were horrified of what was to come. She watched them take up defensive positions. Maybe even giving the whole team a chance…they'll need each…wait. No. No! Not the Kamui!

Kakashi's eyes had turned into Mangekyō Sharingan bearing none other than the Kamui. She gritted her teeth and knew that if they tried to teleport away, that would only throw her centuries of planning out of the window. NO. She knew what she had to do. Speeding through hand seals faster than the speed of light, she clapped her hands together. Roaring out an unknown jutsu, the world began to warp. Kakashi's Kamui warped and changed directions. Sasuke, Naruto and Sakura clung to their sensei in complete fear. The Kamui never felt like this.

"Sasuke!" Naruto cried. "She's let her guard down! We can seal her!"

"Then let's get it on then!" Sasuke roared back. "Keep the Kamui going! The dimension is collapsing!"

Chaos reigned, shaking the world they were fighting in, breaking the terrain and shattering the dimension. Kaguya shut her eyes in relief. Chakra exploded around her, filling her not with dread of fear, but content. The Chibaku Tensei was her final prison and it was where she will remain until someone, anyone, could manage to kill her. She was the bad guy this time. But while she was beaten, she had succeeded.

"Let it end…"

May 1, 2012 – Nevada, USA

Helicopters whirred into the night as men and women rushed back and forth throughout the compound. Sirens blared with the repeated message Evacuate the facility, this is not a drill. A clamor to get to the first transports out of the facility brought a systemized chaos. Personnel were quickly escorted to their armored SUV's engines turned and ready to escape.

S.H.I.E.L.D. agents stood watch, controlling the flow. Moving and giving commands, the facility was on lockdown. Over the chaos, a S.H.I.E.L.D. helicopter landed upon the landing pad, blades slowing to sit still. Suddenly, from within, the helicopter door swung open to reveal none other than S.H.I.E.L.D. agent, Maria Hill and S.H.I.E.L.D. director, Nick Fury. Obviously in distress, the two kept their worries to themselves, knowing full well that the calm they'd manage to bring would be destroyed the moment weakness was shown.

The two walked along with Agent Phil Coulson, as he filled them in on the situation. The tesseract was being tested on after Howard Stark first found the damned thing. The power that was accomplished through Hydra and their machines was a power that S.H.I.E.L.D. had wanted for decades. The power to keep true peace. Nevertheless, their attempts had been futile, always ending with something blowing up or many somethings blowing up. Nick Fury was growing impatient and the money that was getting funneled for their experiments seemed like it was going to waste.

They had one goal in mind, understand the tesseract and unlock the secrets within. A remarkable device, always glowing like a force of unlimited power. To harness it was the ultimate goal. Director Fury, after a quick and chaste conversation with Agent Hill, he entered the testing area with little to no idea of what he was about to witness. Scientists ran back and forth, calculating, computing and writing reports on clipboards. The centerpiece of the room though, was the cube, lodged into a type of energy funneling device. Given the wires and glowing machines.

"Talk to me Doctor!"

"Director!" Doctor Erik Selvig looked up. "The tesseract is misbehaving."

"Is that some kind of joke?" Nick Fury asked.

"Not at all." Selvig sighed. "It's not just acting, it's behaving."

"Where's Agent Barton?" Director Fury asked.

Doctor Erik Selvig didn't even look up to the one-eyed man. "The Hawk? He's just in his nest."

"Doctor!" Another scientist called. "We're getting a series of ripples throughout the tesseracts magnetic sphere…and…something else entirely! We've never seen such energy before!"

"Let me see!" Erik rushed forward, pushing the scientist aside. "Director, I advise that you clear the way! We don't know what's happening here!"

Before the two could make any movements, a great blue beam rushed from the tesseract and into the containment field. It grew larger and brighter, filling the area with blue energy unlike anything seen before. Assault rifles were raised and pistols were drawn. Scientists backed away, hiding behind the S.H.I.E.L.D. gunmen. Almost complete uncertainty grew within them, watching the glowing sphere only grow bigger.

Slowly but surely, the sphere began to fade revealing a dark silhouette of a man. In his hands was a spiked scepter, glowing ominously and a sickening smirk spread across his face. Fury stared at him with a confused expression, hand dropping to the Sig Sauer strapped to his thigh. Around him, S.H.I.E.L.D. agents raised their MP5 submachine guns towards the newcomer, tentatively advancing closer to the man.

He rose, scepter glowing with a terrifying hue. The smile had grown as well, practically ripping his face in two. He watched them, almost as confused as he was. He couldn't sense anything from them; they were sentient meat bags. There was no power here, no one to challenge him. But that was when he saw it. The glowing tesseract, the object the object the eternally infuriated Thanos wanted so dearly. It was just like he remembered, except this time it was practically pulsating with energy.

These humans don't know what they're doing. Loki smirked, rising with the scepter glowing as well. Let me teach them!

He shot the scepter forward, a powerful blast of energy rushed ahead. Men and women were forced into the air, dead before they hit the ground. Machines and wires were cut, swinging in all directions raining sparks. Bullets were shot at the Frost Giant only to bounce off of his impenetrable armor. Loki needed to test himself; he wanted to use this power to its fullest extent.

Jumping forward, kicking one of the S.H.E.I.L.D. gunmen away, he lodged the scepter into a man, killing him immediately. Almost like a gust of wind, two knives were hurled, embedding into the necks of unsuspecting agents. Humans were weak compared to a Frost Giant, it would seem. Kicking the corpse from his scepter, his eyes were only for the tesseract.

Sensing something from behind, he ducked, raising the scepter to the chest of the agent. Slowly but surely, energy spiraled up to the man's eyes, hypnotizing him. Loki smiled; the man was now no more than a thrall. No words were shared between the newcomer and his victims. The energy the tesseract had released was beginning to build in the containment field and build with pressure. The Frost Giant quickly noticed Nick Fury shoving the tesseract into a suitcase and knew he had to be quick. Soon enough the energy would go critical and everything would be destroyed.

"I don't think so." Loki walked forward, ready to forcefully take the suitcase.

Channeling the power of the scepter, a blast of light forced the suitcase from Nick Fury's hands and forcing the man to the other side of the room, close to the shuddering containment field. Agent Barton quickly made a move to salvage the situation, but it was no use. Just like the agent before, the scepter's power spread and made Barton no less than a hungry thrall. His eyes were no longer brown but instead, an icy, empty blue.

"Drop the suitcase!" Fury's voice sounded struggled. He raised his Sig Sauer, aiming down the iron sights.

Dust fell from the ceiling. All survivors of Loki's entrance looked onward in horror. Cracks formed against the concrete containment field as the tesseracts energy built once more. Fury rushed ahead, trying his hardest to get as far away as possible, all the while firing off a few shots towards the god. Fury slid against the tiled floor.

"Director, do you hear that?" Erik asked worriedly. "Something else is coming through the tesseracts energy sphere!"

"Another?!" Fury roared.

"Another?" Loki turned to the compressing energy with a raised brow. "I was not expecting another…"

Grah!

All eyes went as wide as plates. The shout sounded human…but animalistic at the same time. Power unlike anything felt before, washed over them in waves. Even Loki trembled in its aura. Finally, four silhouettes formed in the compressed ball of light. Loki clenched his jaw, gripping his scepter with a vice-like grip. Not these four again!

"Hey!"

The tesseracts power exploded outwards, covering them in calm and fear. From the epicenter stood four very unlikely individuals. Very, very unlikely individuals. The tallest had two red eyes with strangely shaped pupils and gravity defying grey hair. He wore a headband with a metal plate, etched with a strange symbol. Around his torso was a burned and tattered flak jacket of sorts. Next to him was an even stranger enigma; she had pink hair. It seemed natural yet, unnatural. Green eyes; a stark contrast to the other three, and dressed somewhat the same as the first man.

But it was the two boys that really caught their attention; one had a purple eye with weird ripple effects! He was covered in a purple flame and gave off an aura of darkness. His left hand was exploding with black lightning. The centerpiece though, was a boy of same height, but glowed with golden fire. His face was adorned with thick black lines; three on each cheek and strange black markings all over his body. Power radiated off of him in a magnitude that not even the tesseract managed. In his hands, two black staves that seemed to absorb light wherever it was.

Fury watched the world around them calm down and the power of the tesseract waned in their presence. The cracks stopped forming and the facility stopped shuddering beneath the tesseracts rage. But it was Loki's expression that had him worried. He slowly raised his pistol, unsure of whom to shoot at. But as they say, actions speak louder than words.

"You again?!" The golden boy roared. "Why you – I'll shove this staff into your gut you bastard! Sasuke, come on!"

I really hoped you liked it?

Ja ne!
