This is one of the portals from Naruto's Tale that opens up in the Agent of SHIELD universe.

Not all the portals open at the same time. Each fics portal opens based on the syncing order, depending on which one I publish/update first. They also do not experience time at the same rate; some will not 'flow' the same for all of them, but they will all sync up about once a month. For some, time will stop for the ones in universes where the series has been concluded. The knowledge gained by Sakura and him going forward is stored in a living database and shared between all versions. The same goes for when one gains power/ability by merging with one universe's counterpart. So, suppose one of them gets a new power/ability through merging with said universe's counterpart. In that case, all the others will receive it via a surge of DNA-encoded energy modifying their DNA and all knowledge gained since the last 'Sync up' point when they 'Sync' up. Also, due to Sakura's life force being bound to Naruto's now infinite one, she and their children will have the same healing factor, which is about the same level as Wolverine's from Marvel Comics.

It's like Venom's hivemind, except they only share knowledge(and powers/abilities because I feel like it) that each set has obtained and anything else going forward.

I will have to say that this Naruto is a bit OOC, and I apologize for that. If you don't like it, stop reading. I am doing this as a hobby.

(Scene Break/Time Skip)


(Extremis Explosion Site)

Melinda May, Leo Fitz, and Jemma Simmons were investigating when suddenly a portal opened in the middle of the room, getting May, Fitz, and Simmons's attention. Shortly after it opened, Naruto and Sakura stepped out before the portal closed behind them. Just then, Naruto and Sakura were overcome with a wave of energy and knowledge.

May, Fitz, and Simmons's attention was immediately drawn to Naruto's horn-like protrusions, his blue and purple Rinnegans, the Rinne Sharingan on his forehead, his platinum blonde and crimson hair, the 9 truth-seeking orbs hoving behind him, as well as how freakishly tall he was, and Sakura's pink hair. May instantly went on guard getting their attention.

"Who and what are you?" May asked in a demanding tone

"There is no record of us on this Earth. My name is Naruto Uzumaki, and this is my wife, Sakura Uzumaki. We are multiversal travelers, human-alien hybrid in my case and human in my wife's case, looking for a new life." Naruto answered before he noticed Fitz's drone case with the SHIELD logo. "Ah, so you guys are SHIELD, and that both complicates things and makes things easier."

"How do you know we are SHIELD?" Fitz asked curiously

"Because I recognize that SHIELD logo on your drone case from another version of myself who is an SHIELD agent in another universe." Naruto answered

"What do you mean another universe?" May asked

"As I said, we are multiversal travelers from another universe." Naruto answered before noticing their surroundings, "The hell happened here?"

"Lab explosion." May answered, "You two will have to come with us."

Naruto and Sakura just looked at one another before shrugging their shoulders. Naruto applied a permanent genjutsu to himself, hiding his horn-like protrusions, Rinnegan, and Rinne Sharingan.


(Hours later – The Bus)

"You're telling me that a portal just opened in the room, and they stepped out before it closed? And that they claim there is no record of them on Earth?" Coulson asked, slightly skeptical, looking at Naruto and Sakura

Like May had said, they brought Naruto and Sakura back to the 'Bus' as they called it. Ward had yet to wake up from the stunt that Coulson had pulled. Considering Naruto's appearance and Sakura's pink hair, Coulson found it highly believable. But he would still have to verify that there was no record of them on Earth.

"They claim to be multiversal travelers looking for a new life." May answered

"I'll have to verify their claim about there being no record of them on Earth. For now, we'll keep an eye on them, keep them close." Coulson stated


(An hour later – The Bus – Command Center)

It turned out that Naruto was telling them the truth. There was no record of them on Earth, which was incredibly rare, meaning they weren't from 'Earth'. Which also meant they couldn't just let them go, similar to Skye. Coulson, May, Fitz, Simmons, and Skye are gathered around a holo table as Coulson places a driver's license on it, allowing it to be scanned before several pieces of information are brought up on the table.

"Michael Peterson. Factory worker, separated, with one kid." Coulson listed off as he walked around the table, "Gets injured, gets laid off, wife jumps ship. Good guy got some bad breaks. The best guess is somebody told him they could make him strong again. Make him super."

"Who has the tech to do that? And why would they want to?" May asked

"Fitz, what do we have from the security footage?" Coulson asked, "Before the blast."

Fitz tapped a few things on the table, and a fuzzy picture of two men, presumably a patient and his doctor, appeared on the big screen.

"What are we seeing?" May asked

"Two men, an angry patient, and presumably a doctor of some sort." Naruto answered, stating what was obvious before Coulson gave Fitz and Simmons a look

"The data is corrupt." Simmons stated

"Yeah, like Cold War Russia corrupt." Fitz added, "I can't sync the time code with the video."

"I can help with that." Naruto said, "If you want, that is."

"Go ahead." Coulson said before Naruto's hand was enveloped by silver nanites, shocking everyone before he placed his hand on the table

'MINATO, see if you can sync the time code with the video and sharpen the image.' Naruto ordered

"Of course, Master." MINATO said before he went to work.

They all watched in real-time as the image sharpened and became clearer. After about a minute, Naruto removed his hand from the table, and the silver nanites disappeared into his skin.

"Go ahead and try it now." Naruto ordered

"I'll be. Whatever you did it's usable now." Fitz said, "What did you do?"

"Had my AI do what he could to clean it up and make it useable." Naruto answered

"And what was that stuff that enveloped your hand?" Simmons asked

"High Tech, Bio-Metallic Matter-Absorbing Nanites. I have a symbiote made of them that lives within my body. Allows for seamless interaction between me and technology I touch." Naruto answered, leaving Fitz and Simmons gobsmacked

"That kind of tech has to be several millennia ahead of anything we have on Earth." Simmons said

"And you're AI is part of this symbiote?" Fitz asked, incredibly interested

"No, it's a separate part that lives within a special housing I made that allows for seamless integration with my body and central nervous system, allowing me to communicate with it using my thoughts." Naruto answered before he turned around and showed them the Kryptonian Neural Interface he made installed on the base of his neck, "Hooks directly into my central nervous system."

"Your species must be far more advanced than Earth." Simmons stated, causing Naruto to adopt a sheepish look

"Maybe a few millennia's more advanced than this Earth's." Naruto commented

"Why don't we play the video now." Coulson said

"Did this lab have multiple camera angles?" Naruto asked

"Yes. Why?" Fitz asked

"If you give me the data from all the cameras, I might be able to generate a 3D holographic projection of the recording." Naruto answered

"I have audio data from my shotgun mic I had pointed at the lab while I was running surveillance on the lab before the explosion went off." Skye added, "The digital files are in my van. It has too much background noise for me, but you could probably do something with it."

"Your van's here. But you were right. We couldn't decrypt the files." Coulson said

"The encryption's coupled to the GPS. Get my van back to that alley, and then I'm in business." Skye explained

"Agent May will escort you." Coulson said as May made her way out of the command center, "And on your way out, wake up Ward."


(An hour later – Lab of The Bus)

Naruto and Fitz were waiting for Skye to send them the audio file while Simmons and Sakura were going full scientist/medic mode on something Simmons had found at the explosion site with Coulson watching them. A scientist in Simmons's case and a medic in Sakura's case after they failed to get Naruto to tell them more about the alien part of his lineage and tech.

"Audio file should be coming through. It's not compressed, so it might take a minute." Skye said over the phone

"Yeah, yeah, I'm getting it." Fitz said, "So, when you get back, I'll show you my thing."

This immediately got Sakura and Naruto's attention. Simmons seemed unfazed.

"A thing. It's not…It's my hardware. My equipment! Let's hang up." Fitz said in a panic before he quickly ended the call and took out his earpiece before he noticed the look Naruto and Sakura were giving him

"I assure you I was not insinuating anything sexual." Fitz said, "And how can you seamlessly change your apperance?"

"Using a transformation technique so everyone only sees what I want them to see in public: an average freakishly tall man with blue eyes and hair with platinum blond roots and crimson tips." Naruto explained

"What's a transformation technique?" Fitz and Simmons asked

"It's a technique that uses chakra to change my appearance into what I want people to see. It's not limited to just hiding stuff. I can entirely turn myself into someone else looks wise if I want to." Naruto answered, "I put it up because we had to go into public to get back here. I kept it up because I don't want to freak people out and cause a panic."

"When you say chakra, do you mean that stuff monks talk about?" Simmons asked

"Similar terms and basic ideas of internal energy centers, but what my wife and I have is highly versatile in what it can be used for." Naruto answered, "Now, get back to what you guys were doing. Don't let me distract you."

Simmons reluctantly returned to what she was doing, drilling into what she had brought back from the explosion site.

"So the alien metal wasn't the explosive?" Coulson asked

"I assumed from the break pattern and dispersion that it was. But it's just dripping with gamma radiation and…" Simmons answered before the drill finally broke through and started dripping onto the petri dish she had set up underneath it. "And now it really is dripping. Fun."

Just then, Ward walked in and was momentarily taken aback by Naruto's appearance, "So what did that get us?"

"Skye's sending us the rest of her decrypted files on Centipede, but we have her audio now. So all that's left to do is give it all to Naruto and have him create a 3D holographic projection of the video." Fitz answered before he handed Naruto a USB drive with all the necessary data.

Naruto's hand was again enveloped by silver nanites, 'MINATO, create a 3D hologram of the explosion site from this data.'

"Of course, Master." MINATO said

After a few minutes, the nanites that enveloped Naruto's hand clumped up before a beam of light shot out into the cargo bay, turning into a hologram of the time before the explosion.

"Magnificent." Fitz commented

Ward immediately took note of the case between the two men before it started playing, "Explosive in the case?"

"Please, calm down. Just let me check your vitals." The 'doctor' pleaded

"I feel fine. I want to feel more. Where's the doctor? Where is she!?" The 'patient' demanded

"If you don't settle down, I'll have you sedated." The 'doctor' threatened

"Where is she?!" The 'patient' demanded before picking up a chair and slamming it on a table, breaking it

"Wait, did you see that on his arm?" Fitz asked, "Rewind it a few seconds."

The video began rewinding until the 'patient's' forearm was exposed, "Stop." Fitz said before Ward got closer to the hologram of the 'patient's' forearm

"What does it look like to you?" Coulson asked as Ward finally got a good look at it

"A centipede." Ward answered

"It's an intravenous filter for his blood. This goo, sir. Very similar to the serum Dr. Erskine developed in the 40's for the…" Simmons explained before Coulson turned back to the hologram

"Super-soldiers." Coulson finished getting Naruto and Sakura's attention

"I'm reading alien metal, gamma radiation, the serum. Every known source of superpower, thrown into a blender." Simmons explained

"You mean you guys have already encountered aliens on this planet?" Naruto asked

"Yeah. Several, in fact, including an army of them." Coulson answered

Naruto and Sakura just looked at one another, silently deciding on the same thing. "So then SHIELD of this universe has already seen and encountered aliens with different anatomy and appearance than humans?"

"Yes, why?" Coulson answered

"Then that means that I only need to maintain my transformation in public since you have experience with other aliens." Naruto said

"We should report this to Director Fury." Ward commented

"I will after we deal with this whole Centipede ordeal." Coulson said, "Anyways. We need to see the origin of the blast. Run it back from the last point recorded."

Naruto quickly skipped to the end of the recording before slowly rewinding it. They watched the explosion rewound until it reformed into the 'patient' the 'doctor' was speaking to with some kind of energy flowing through his veins before Coulson got closer.

"Extremis. It's new. Completely unstable." Coulson explained before turning back to Simmons

"Poor man didn't bring an explosive. And Mike has the same stuff in his system." Simmons commented

"Well, judging by his strength level, a lot more." Ward commented

"So then, any minute now, Mike is gonna explode?" Fitz asked

"He'll take out anyone within a two-block radius." Simmons answered before Coulson turned around to look at Ward

"Well, you wanted a bomb." Coulson said before walking away as the hologram disappeared and the clump of Nanites retreated back into his body


(An hour later – The Lab)

After further research on the Centipede serum, Fitz and Simmons discovered that the explosion was caused by a chemical reaction within the host's body. After bringing this to Coulson's attention, he ordered them to find a nonlethal way to deal with Mike Peterson. Fitz and Simmons ran tests and simulations to devise a non-lethal solution to stop Mike from exploding.

"The problem with Extremis is its volatility. It's supposed to regenerate tissue, but it often leads to thermal runaway and then... boom." Fitz said, looking at the big screen of the lab

"Yes, and our current stabilizing agents aren't selective enough. They either inhibit Extremis completely or not at all. We need something more... adaptive." Simmons said

"Have you considered using a biochemical regulator that mimics the adaptive properties of Kryptonian cellular structures? They have an inherent ability to regulate and balance absorbed energies." Naruto suggested

"What do you mean Kryptonian cells? That's alien to us, and we have no knowledge on them. How would we even replicate something like that?" Simmons asked, "I'm going to assume that you are suggesting that because you are knowledgeable in it."

Naruto nodded. "I can provide a framework based on their biochemistry. Kryptonian cells use a kind of biological 'feedback loop' to stabilize energy levels. We could design a synthetic pathway that emulates this process in humans."

"So, rather than trying to suppress the Extremis reaction outright, we'd be helping the body to manage it on its own?" Fitz asked

"Exactly. We'd be enhancing the body's natural resilience to the changes Extremis causes. It would be like adding a new regulatory system at the cellular level." Naruto answered

"This could minimize the risk of combustion without compromising the regenerative benefits. It's brilliant!" Simmons said

"I'll help you compile the necessary data and simulate the biochemical interactions. We need to see how it behaves in a controlled environment." Naruto said

"And if our simulations are successful, we could have a way to make Extremis viable for medical use, without the... explosive side effects." Fitz said

"Let's get started. This could be a major breakthrough. Thank you, Naruto." Simmons said

A 'Security Breach' alert appeared on the screen, getting their attention.

"Oh, no! Fitz, what is this nonsense?" Simmons asked

"This isn't me!" Fitz answered, "It's noise. Someone's hacking our secure channel."

"It's longitude and latitude." Coulson said as he walked through the lab, "Mike took Skye. She's telling us where."

"Babe, do you know enough Kryptonians and their cellular structure to help Fitz and Simmons come up with a solution?" Naruto asked, getting a nod from Sakura, "Then I'll leave you here with Fitz and Simmons to help them while I go with Coulson and Ward for backup, considering that this Centipede stuff makes humans superhumans."


(About an hour later – Outside of the train station at the coordinates given by Skye)

Naruto reapplied the transformation technique to make him look human before he, Coulson, and Ward stepped out of the SUV they had pulled up in and made their way toward Skye's van.

"Look at this place. You're gonna risk thousands of lives over some nobody?" Ward asked

"Everyone's a nobody until they are noticed and given a chance to prove themselves." Naruto countered

"I agree with Naruto. Everyone's a nobody until they are noticed and given a chance." Coulson agreed, "Fitz-Simmons and Sakura will come through."

"Mr. Peterson, good morning. We're not a threat; we're here to help. But you're in danger, and we need to take you in." Coulson announced through a megaphone

Several seconds later, Naruto felt a tingling sensation before he sprinted forward as the side door to Skye's van flew off. Thankfully, Naruto got there in time before it hit the police officers and caught it, shocking the officers, Coulson, Ward, Skye, and Mike. Shortly after, Mike grabbed Skye and his son and made a break for the door to the train station. He didn't get very far before the officers, Ward and Coulson, drew their pistols.

Naruto quickly placed the door on the ground before he put himself between the pistols and Mike, Skye, and his son. "Mike, don't make this more difficult than this has to be."

Naruto could sense Mike's fear and desperation. He understood that he didn't mean or want to harm anyone and was just looking out for himself and his son.

"Mike, I know you are scared. Let SHIELD help you before it's too late. I will make sure that nothing bad happens to you." Naruto pleaded before motioning for the officers, Ward and Coulson, to put their pistols away.

Suddenly, Naruto felt another tingling sensation before he heard a gunshot. Instantly, Naruto was on Mike, Skye, and his son, unconsciously putting himself between them and the bullet that had been fired at them. The shotgun bullets bounced right off him and into the ground before the officers, Ward and Coulson, were on high alert, bringing their pistols up, looking for the source of the gunshot.

Using this moment as an opportunity to escape, Mike grabbed his son and Skye before booking it toward the entrance once again, causing Skye to yell. Naruto turned his attention back to Skye, Mike, and his son, only to see Mike holding his son and Skye making a break for the entrance.

Skye was just within grabbing distance of him, Mike and his son being the farthest, and he wasn't about to let Mike take Skye and use her as a hostage. He quickly grabbed her and pulled her out of Mike's grasp and into his chest, protecting her from any more potential gunshots.

Mike saw this and made an attempt to grab Skye again, but he was sucked up by a swirling vortex.

"Ace, get over here!" Skye ordered, quickly extending her hand toward the little boy to grab him

Once Ace and Skye were back within Naruto's protection, they heard another gunshot. Naruto felt more shotgun pellets bounce off his body. Naruto then began moving back toward Ward and Coulson.

"Where's my daddy?" Ace asked worriedly

"He's somewhere safe." Naruto answered before they heard tires screeching as a car sped off down the road. Seeing they were no longer in danger, Naruto turned his attention back to Skye and Ace, "Are either of you hurt?"

"No, we're fine." Skye answered, her heart pounding before he started looking around for Mike, "Where did Mike go?"

"Somewhere safe. Don't worry." Naruto answered

"Babe, we finally got something to stabilize the Extremis in Mike." Sakura informed

"You're bulletproof?" Ward asked

"Yep." Naruto answered

"Where's Peterson?" Coulson asked

"Stored away in stasis." Naruto answered, "He's safe. Fitz-Simmons has a way to keep Mike from going boom now."

"How do you know that?" Coulson asked curiously

"Mental link with my wife." Naruto answered

"Then let's get back to the Bus and see what they came up with." Coulson said


(About an hour later – The Bus)

"So how exactly is this supposed to keep Mike Peterson from going boom?" Coulson asked, eyeing the green vial that was supposed to be the solution to saving Mike

"Agent Coulson, as you're aware, the primary issue with Extremis has been its instability, which can lead to catastrophic thermal reactions in subjects. Our traditional methods of addressing this have been largely suppressive, which, while effective in preventing combustion, also negate the regenerative properties that make Extremis potentially valuable for medical use." Simmons explained

"Right, the cure often kills the patient before the disease can. So, what's different now?" Coulson asked

"We've taken inspiration from an unlikely source—Kryptonian biology, as Naruto introduced us. Kryptonian cells exhibit a remarkable ability to regulate absorbed solar energy through an internal feedback mechanism that maintains balance at the cellular level." Simmons explained

"Basically, their cells can handle power surges without going haywire, which got us thinking about Extremis." Fitz added

"Exactly, Fitz. We've devised a synthetic pathway that mimics this Kryptonian cellular feedback. It's a biochemical regulator that integrates with human cells, enhancing their ability to manage the thermal energy produced by Extremis. Instead of suppressing the Extremis reaction, this regulator helps the body adapt to it." Simmons continued

"So, it's like adding a safety valve?" Coulson asked

"Precisely. This regulator acts as a safety mechanism, preventing the energy from reaching a critical point where it would cause combustion. This should retain the healing capabilities of Extremis while mitigating its most dangerous side effect." Simmons answered

"Sounds promising. Let's see if it keeps Mike from going boom." Coulson said before he turned to Naruto

"Babe, you destroyed the data used to make the solution, right?" Naruto asked,"I don't want it to be used to create super soldiers."

"Yes, although I did upload the data for the solution to the Universal Data Matrix for us in case it is needed again." Sakura answered

"Am I to assume that you are talking to your wife?" Coulson asked

"Yes." Naruto answered, "Let's go outside on the off chance this doesn't work."

Once Fitz-Simmons, Sakura, Coulson, and Skye were outside, Naruto 'unsealed' Mike, who was slightly disorientated. Seeing they were away from civilization, he had opted to release the transformation technique, allowing his Rinne Sharingan, Rinnegan, and horn-like protrusions to be seen.

"Where am I, and where is my son!?" Mike demanded. Everyone could see the Extremis in his veins start to become unstable. Naruto quickly injected the green solution into Mike, and they watched as the Extremis stabilized.

"It worked." Simmons said with a sigh of relief

"What did you just inject me with!?" Mike asked with hostility

"Your son is being escorted to your sister's residence with a team of SHIELD agents. As for what we injected you with, it's something that should prevent the Extremis inside you from blowing up." Coulson answered, "Given your enhanced strength and resilience because of the Centipede serum, SHIELD has taken an interest in you. That interest has increased since the extremis part of your centipede serum has stabilized. On behalf of SHIELD, I would like to extend an offer to join SHIELD."

As Naruto and Sakura started walking back to the Bus, Skye decided to get his attention.

"Naruto, I… Thank you. Back there, I don't know what would have happened if you hadn't been there." Skye thanked, breathing deeply, a slight tremor in her voice

Naruto stopped and turned to face her, a gentle smile softening his otherwise stoic expression, "You don't need to thank me, Skye. It's what family does—they look out for each other."

"Family…" Skye said, a bit taken aback, her voice softening

Sakura took a few steps forward, her tone warm and inviting, "Yes, family. We might not be related by blood, but that doesn't mean we can't care about each other like one."

Naruto nods, his eyes reflecting sincerity, "Exactly. Where we come from, bonds are what define us, not just blood. You're brave, Skye. And brave people are always welcome in our family."

Skye smiles, a flush of warmth spreading across her cheeks, "I've never really had that… a family, I mean. It's always been just me, moving from one place to another."

Sakura steps closer, her demeanor empathetic, "Well, you're not alone anymore. We're here, and we're not going anywhere. Isn't that right, Naruto?"

Naruto's smile broadens, nodding, "Absolutely. We've got your back, Skye. And hey, we can be quite the handful, too, so you might even end up looking out for us more often than you think."

Skye laughs, the tension easing from her shoulders, "I think I can handle that. It's nice, you know, having someone... or multiple people, watching over me."

"Just wait until you have to deal with this one when he gets stubborn." Sakura said playfully while she nudged Naruto lightly

Naruto chuckles, raising an eyebrow, "Hey, I'm not the only stubborn one around here."

Skye giggling, and feeling more relaxed, "I guess I'm joining quite the team then."

Sakura gently tugs Skye closer, "More than a team, Skye. A family. Welcome to it."

Skye looked between Naruto and Sakura, her voice steadier, "Thank you both. For saving me, and for… this. I think I'm going to like being part of your family."

Naruto grinned, "That's the spirit! And remember, no matter what happens, we stick together. That's what families do."
