Chapter One: A Brave New World.

"Abandon all hope, ye who enter here."

A brief warning, that was all that was written atop the gated entrance to this hellish hellhole. Those who looked upon the gates of gold were given the impression that what lay ahead was a paradisal world, its charm was irresistible and filled you with a sort of urgency that coaxed you into walking through it's doors. Yet what lay beyond couldn't have been any different, all that remained was an ever-expansive realm of fire and brimstone. One that slowly but surely twisted even the purest of men into soulless unsightly creatures bound to this dead world. There was no escape, no purpose to its existence besides to keep those who were unfortunate enough to find themselves in its company trapped for all of eternity.

Such was the fate for one Naruto Uzumaki.

Naruto had trudged the plains of this unknown world for what had felt like eons, nothing existed here besides demons and apparitions that seemingly took great pleasure in his futile efforts to escape. He had tried everything that had come to his mind, even destroyed this world a few times but was seemingly always returned back to those infernal gates over and over again like he was trapped in some sort of sick twisted game.

The events that had unfolded to bring him here were still a little bit hazy, it had all happened so fast. All he remembered was her mocking smile and then a powerful pull as he was thrust into an ever-encompassing darkness.

Naruto stumbled upon a hilltop, his gaze fell upon a large rock inscribed with the leaf insignia and he let out a terribly sad sigh. "I'm back here again huh…I wonder if you would have found your away out of here, Sasuke." Kaguya had played them all or at least was prepared to lose from the very beginning. Her final actions before she had been returned back to her prison was one marred with blood.

All-Killing-Ash-Bones.

The pinnacle of Kaguya's deadly will, the bones were capable of killing anybody with just a mere scratch. In the darkness of her void, it was impossible to detect the dozens of bone spears that she had thrown. Naruto had only survived due to simple luck, they had all missed him by a mere inch. Red spiralling eyes stared softly at the grave of his rival and friend, he could still remember the bloody sight of Sasuke dying in front of him.

Those fleeting words.

And his promise to return home and change things for the better.

Who would have thought that this would become the one time that he could not keep his promise?

"Waah Waah."

Naruto was snapped out of his stupor by the distinct sound of a child crying, he immediately found himself rushing towards the sound, hoping that it was as he had heard. To his surprise, in the middle of a clearing lay a blonde boy no older than six years old. Naruto landed gracefully behind the boy, his RinneSharingan narrowed slightly wondering if this place was playing tricks on him again.

"Hello…" Naruto said.

The young child spun around; hands stretched outwards in a fashion that looked comical but nonetheless proved to show that he was far from helpless. Naruto's truth-seeking balls instantly wrapped around his body as powerful rays of energy shot out from the heavens and zoomed towards him with impossible accuracy. They blew his shield apart; he was forced to substitute himself with a rock to get out of the blast zone that literally atmozied everything in it's way.

What is Kami's name was this boy? He had never seen a child wield that much power.

Naruto raised his hand in surrender before he could be assaulted once more, "Hey, hey…I'm not here to hurt you." He heard the boy sniffle slightly and Naruto made his way cautiously to him, "Are you okay?"

"H-home, I want to go home." He said softly. "Can you take me home, Mister…"

"Naruto…I'm Naruto." He gave the boy his outstretched hand, which he took gratefully. "What's your name?"

"Franklin. Franklin Richards." He whimpered out

"How did you get here, Franklin?" Naruto asked.

"I-I was just trying to show my dad I could control my powers." Naruto sighed, so he ended up here by accident and now he couldn't escape as well. Greaaat, how would he break it the boy that there was no escaping here.

"Come on…" Naruto relented, "It's too dangerous out here." Franklin snorted, completely affronted by the comment that there was anything more powerful than he was.

"I'm the strongest." Franklin huffed. "No one can…" Naruto immediately grabbed Franklin as the earth below them shattered, fire rose from the ground like a geyser and a deep guttural roar echoed from the depths below. Naruto and Franklin landed some clicks away from the large crater, steam and smoke obscured their vision, but they could still feel its presence.

Clap Clap

"Imagine my surprise when I sensed a reality warper in my dimension." A pale green-haired man dressed like some sort of jester with a cape; the man's face was permanently twisted in a sort of sickening smile. "And a young child, nonetheless. I couldn't possibly resist not revealing myself." He laughed maniacally, green fire danced around his body as he raised one of his bony hands. The world shifted, the entity immediately appeared in front of them, Naruto's tried to kick him, but his body just phased through. He fired a powerful a psionic blast that send Naruto spiraling away.

Franklin murmured, "Nightmares…You're not real."

"Oh, but I am very much real." The apparition cackled. "And you are going to be mine." Franklin felt his body freeze as the man's eyes glowed with power, he could feel the entity enter his mind, he tried his best to fight against the powerful telepathic attack but to no avail. Franklin's body had been consumed by the ethereal flame of the apparition like entity.

The entity in Franklin's body stretched his new body, testing it out."Not quite as study as I had hoped but it will do quite nicely." He turned towards Naruto, a mocking smile played on his lips, "And you failed once more, Uzumaki. I'm not surprised really, after all this time, you had yet to truly understand what this place is."

Naruto growled, "I don't care." His chakra exploded outwards as he took on his Sage of Six Paths Mode, "Get out of the kid or I will kill you."

Franklin sneered, "Such power, it's quite sad that you already have that infernal fox inside your stomach, otherwise you would have made a great host." He raised his hand, the Rasenshuriken heading towards him was simply willed out of my existence, Naruto had never seen anything like it, one second it was there and the next it was gone. Franklin raised his hand.

Time froze.

Franklin approached Naruto's prone form, "It's unfortunate that you must die." He conjured one of his blades and stabbed straight into Naruto's heart before he allowed to time to resume once more.

Blood pooled out of Naruto's mouth as he gasped in surprise, runes spread out from the blade and across his body. He felt his body begin to shut down, his healing factor was useless against the possessed Franklin's warping powers. He grinned bloodily as his RinneSharingan spun one last time before his body crumbled to the ground, dead.

Franklin drew his blade from Naruto's chest, he gave the Uzumaki one castaway look. Nothing could defeat him in this body, the other lords would not stand a chance against him. Soon, Nightmare would rule the underworld and then, he would go onto the rule the entire universe.

"Where are you going?" Franklin heard the softest of whisper's behind him, he spun around to see him staring at the hateful gaze of Uzumaki Naruto. He couldn't possibly react in time as Naruto's palm slammed straight into his stomach, chakra pulsed into his body and Naruto activated the Yang seal, the possessed Franklin screamed in pain.

"H-How?"

Naruto grinned foxily, "Guess you made an error allowing me to fight all your creatures all these years, I've become accustomed to dealing with ghosts like you." Nightmare screamed in anguish as Naruto's yang seal forcefully excavated him from Franklin's body. Naruto's RinneSharingan spun wildly, the apparition turned towards Franklin's unconscious body and began to fly towards it, intent on possessing him once more.

"Fuinjutsu: Uchūkusari Tessou." Naruto slammed his hand's together as he completed the technique. Nightmare felt a powerful tug as dozens of ethereal blue chains shot out from beneath Naruto's feet, he tried to cut them down but they kept multiplying, attaching themselves to his body.

Nightmare felt himself being dragged by adamantine like chains, Naruto grabbed the large scroll strapped to his back and unwound it, revealing a dense and complicated seal array.

"You will pay for this, Uzumaki! I will return." The entity screamed as he was swallowed into the seal in the scroll, Naruto had no doubt that the being would escape eventually but his primary concern was Franklin.

Franklin looked at Naruto with wonder, "Can you teach me how to do that when we get back home." Naruto shook his head in amusement at how quickly the boy had just shaken off being possessed.

The world began to shake rapidly, Franklin let out a cry as he fell to the ground once more, he knew this feeling well, it was the beginning of a dimensional shift. The realm was beginning to break apart without its ruler and soon both Franklin and Naruto found themselves blinded by a powerful white light.

Franklin closed his eyes and used all of his willpower to wish that he was back with his parents.

Doctor Strange prided himself in being the master of all that was arcane, it was after all his duty as Earth's Sorcerer Supreme to ensure that the mystical never interfered with the mundane. His power and expertise were sought all over the planet, if there was ever anything magical going on, he was the guy to call.

"What do you mean, you can't find him." Susan Storm shouted angrily, "Whatever took him was mystical in nature."

Doctor Strange sighed, "It is impossible to detect a reality warper, Susan. And your son vanished off his own accord."

Reed Richards hummed, "And what of your magical instruments, do they not give you the whereabouts of our son."

The Sorcerer Supreme sighed, "Such rituals take time, we must have patience." Susan wasn't having any of it, her son could be lost in the middle of nowhere and they weren't doing anything.

Johnny Storm gently held his sister and whispered words of encouragement, "He's going to be fine, Sue. Remember we're dealing with Franklin here." It did little to soothe her worries but Susan calmed down a little.

The Sanctum chimed, Doctor Strange felt a powerful wave of demonic magic erupt from the Orb of Agammatto. This wasn't good, it could only mean that something major had happened in one of the dimensions belonging to the Hell Lords. He rushed towards the Orb, only to find himself stunned at what he saw. "By the Mists of Hoggoth, how is such a thing possible?" He questioned. The Dream Dimension had been shattered completely, someone or something had managed to defeat Nightmare in his own world.

And they were coming straight here.

A multicoloured rift blew apart in the middle of the room, a blinding light spread throughout the room forcing them all to cover their eyes. Doctor Strange raised a barrier in time as he felt a sudden spike in energy, two figures were spat out of the rift at high velocity, he heard them groan in pain as they collided against the invisible barrier.

The light eventually died down revealing who the two intruders were, Susan Storm was the first to notice that one of them was Franklin. "Franklin!" She shouted and rushed towards her son.

Franklin opened up his eyes at the unforgettable voice of his mother, he smiled brightly, "Yes, Yes…I did it, Naruto." He exclaimed.

Susan scooped him up from Naruto's arms, smiling and hugging her son. "Oh, thank god, Franklin. You had us worried." She stared at him sternly, "Don't ever do that again."

Franklin nodded tearily. "Is Mister Naruto okay, mommy." He asked. Susan peeked over her son's shoulder to see the unconscious form of the teen, "He saved me from the monster."

Gasp

Naruto let out a strangled gasp for air, his mind spun wildly from the spiralling effect of inter-dimensional travel. "Son of a bitch…Never again. I'm never doing that again." As he came to, he found himself in the presence of four bizarrely dressed people and an orange rocklike being.

"Who are you people and where am I?" He demanded, his chakra flexed outwards in an intimidating fashion.

It was moments like this that made Doctor Strange hate his job.

Naruto frowned intensely as he sat comfortably in the presence of one sorcerer supreme and the Fantastic Four. He had apparently arrived in a different world not suprising considering that Franklin didn't at all appear as if he had come from the Elemental Nations. Dr Strange had been the first to greet him, casting a quick charm on him so that they could all understand each other. They had told him who they were, where he was and what had happened to him. Naruto had apparently been trapped in a dream dimension, Dr Strange had said that it could only be assessed through the astral plane and that it was a freak accident that his physical form had gotten trapped there. In return, he had told them everything, or at least as much as he was comfortable with revealing, he told them where he had come from, how he had been trapped in that hellhole for more than a lifetime and how Franklin and he had escaped.

"So I can't go back home?" Naruto asked.

Reed Richards said, "Travelling between different universes is very risky, especially without knowing where you are going, it's like a rolling a dice, only the amount of universes in the multiverse are infinite, so the chances of you landing in your universe is almost zero. And without exact co-ordinates, even if you did somehow reach your universe, the chances you'll just be floating around in space." Reed thought it was better to keep quiet about how even if Naruto landed back home, it was more than likely that he would end up in the distant future rather than at the time that he had left it.

Naruto buried his face in his hand and let out a tired and weary sigh, "Than it was all for nothing."

Reed nodded. "I'm sorry I can't be off more help." Susan nudged her husband and Reed quickly added, "Whilst I cannot give you what you seek, all I can give you is a place to stay until you become more accustomed to life on this world."

Johnny Storm nodded. "It's totally cool with me, anybody who saves my nephew is good in my book."

Franklin jumped up and down excitedly, "And you can show me how you did that thing with your eyes." Susan Storm looked at her son with amusement, she had never seen him so excited to learn something though she was also certainly intrigued by this new addition's powerset.

Doctor Strange sat silently, judging the boy in front of him with intense scrutiny. Barely older than 17, Naruto Uzumaki had been through enough suffering to last a hundred lifetimes. The fact that he had not gone insane from it all was a miracle in itself, Strange couldn't imagine anybody lasting in the Dream Dimension for that long without losing themselves to Nightmare's games.

A part of him feared that he was letting someone who could potentially pose a huge threat to them into their world, the boy was reluctant to give them any historical context of his land beside a brief rundown, he had come from a place called the Elemental Nations. The dimension was run-down with war and strife, it was primitive and militaristic as a posed to this world. From what little information that he had been given, it was easy to surmise that Naruto had been trained from a very young age, a weaponized child soldier that knew nothing besides to fight.

Naruto's eyes flickered towards the silent sorcerer, he knew that look well, he had seen all the time on the old man Tsuchikage's face. "I know what you're thinking," Naruto said.

"You're wondering if I am a threat to your world?" He made no indication to answer but Naruto could surmise by the Sorcerer's grimace. "I don't blame you or anything, I'd probably do the same if I was Hokage. The answer is no, I'm not a threat to you or your world. You may not believe this but I'm tired of fighting even if it's all I know."

Doctor Strange merely nodded, his magic sensed no deception from him.

Johnny Storm slapped his hands together, "Good, great. Let's get going then, I'm bored, and all of these artifacts give me the creeps." He shuddered as he stared at the skull on the desk that had green mist billowing out of its mouth.

The Fantastic Four and Franklin began to make their way out of the room. Doctor Strange said, "I will continue to research how you ended up in the Dream Dimension. Perhaps it may lead to a way you can get back home."

Naruto gave the Sorcerer a thankful nod and headed out of the room. "Oh, before I forget." He threw a scroll towards Doctor Strange, "You can start by asking the demon." Doctor Strange appeared stupefied at the prospect that an entity like Nightmare could be sealed in a flimsy piece of paper. He wondered how the world would react to the presence of a new superpower, once the young Uzumaki stepped out of the Sanctum, there would be no stopping the world from sensing his presence. That vast amount energy brimming within in the boy was akin to a vast ocean.

All around the world and beyond, they felt Naruto's power as he took his first step into this new world.

Author's Note: Hey guys, I hope wherever you are life is treating you well and you're keeping safe. This is my new story; some of you asked for a marvel crossover where Naruto travels to the Marvel Universe, well, here it is. I am going to draw inspiration from the comics, MCU and the cartoons like X-Men Evolution, Earth's Mightiest Heroes and Spectacular Spider-man. Since I'm more familiar with the X-men and Avengers more than any other group, I'll primarily focus on those story arcs.

Naruto is more powerful than his normal self, blessing of having a pair of RinneSharingan's and having an eternity to train in the Dream Dimension. But he won't be so powerful that he could curbstomp planetary level characters like Doctor Strange and Thor.

So what did you guys think? Leave a review, I really enjoy appreciate your feedback.

Thanks for reading and hopefully, I will be able to update in the coming week, though if I don't it's probably because med school has us really busy.

Note: I edited a few things that some errors that you guys PM'd me about. :) Also Franklin can understand Naruto because he is a reality warper and his power is very passive.
