A burst of inspiration made me return to this story!

That said, I did NOT like how this chapter was going. As in, at all. My version from before was boring, and I'm pretty sure that's why I stopped writing it for so long. Just different ways of expositiong how Naruto's Power Suit looks and what it can do in battle.

So I decided to just… skip what I had planned to show here. Out with the experimentation, and in with seeing Naruto using the Fusion Suit afterwards.

…yes, this does means that many of my past stories that seem abandoned may return if I ever get an idea that breaks their current Author's Block just like is happening right here and now.

That said, please don't be too harsh. I have not written for some time, this story for even longer, and as short as this one was I wrote it in bursts in five days.

IIIII

"Everything seems alright here," Naruto's voice came from Kakashi's earpiece. Nifty thing to have, those, even if a bit too fragile to use in any big-rank missions.

"Great, and how is your air?", the jonin asked mid giving a thumbs up to the workers finishing the bridge (well, honestly mostly fixing the damages his fight with Zabuza caused).

"No change, same as when I just came down here," came the… pleased reply.

"I thought you'd be bored by now."

"Are you kidding me? Even if I wasn't testing this armor thingy do you have any idea how cool it is underwater?"

"Can't say I have, no," he replied absentmindedly. While he was aware of some people with interest for just diving to see the sights, Kakashi himself never bothered. "But you better come up, it is almost lunch time and seems like there is not much more that they need you to… scan."

"Coming up!" came the reply, not long before he could see the orange underwater shape approaching land, until Naruto was confident enough to jump out from there.

It was a… curious piece of clothing. At the moment Naruto woke up, still slowly recovering from what Kakashi supposed was a suicide attack, he only had what was basically a very tight orange jumpsuit. As in, "make it green and you would think he was being trained by Gai" tight jumpsuit.

But as he recovered it was becoming closer and closer to the original form. For now, his arms and legs had some "muscle fiber" regrowing on top of the jumpsuit, and what seemed like a green bracelet in is right wrist and small spikes in his left forearm.

The most important at the moment was the near-red helmet that, apparently, was good enough to filter air from water even if worn underwater already – as Naruto had forgotten to wear it before jumping in.
And that was still the less surprising of the two features they found out about it.

"So, besides the weird symbols I still have no idea what they mean," Naruto started, activating the helmet's… "built-in" communicator so the sound came out even while wearing the helmet, just with a radio-like tinge, "but if I learned enough from old man Tazuna the Scan says everything is fine."

Kakashi nodded, trying not to show anything to the happy workers around them.

They took it all as just another ninja weirdness, so they did not know how utterly bizarre what Naruto just said was even for them.

Oh, don't take him wrong. It was a Bloodline Limit, so it was already weird.

But there is "make ice" weird like Haku, "x-ray vision" like the Hyuga's Byakugan…
And he was pretty aware how the Sharingan utterly breaks… everything, since even more than the slowdown vision and learning any technique it seems, Kakashi's eye had its Mangekyo unlocked and that let him basically break a hole in space.

But then there was Naruto's… suit, he felt to be a more proper term, since it seemed that the armor grew from it.

Oh, sure, he was an Uzumaki and Uzumakis were… legends of weirdness, really. After all, if reports were right his mother's chains had been able to hold down the Kyubi even while she was dying from… well, having it forcefully removed. And there were supposedly other Bloodline Limits of the clan even more broken. Add to them their common skill with understanding and using seals…

But that helmet had better connection to the radio system than his own, ANBU-level earpiece. And this "Scan vision", that after some time looking hard at something analyzed and recorded it, showing to Naruto in that "green glass" as much as the boy could know (plus some symbols he had no idea of) and that he could re-read later… somehow, together with some other recorded things with weird symbols and clearly something wrong and—

It made no sense! It felt like it was better tech than what they had, but when Kakashi checked with his (admittedly not so great) medical jutsu it was clearly a part of Naruto's body just like Haku had theorized (Kakashi seemed to even see nerves from the suit connected to his body).

So… he decided to do his best to not think about it. Just… help Naruto with whatever he learned about it.

Yes, ignore the insanity and just adapt to the fallout. The tested and true method of surviving living around an Uzumaki.

Speaking of around the Uzumaki, he was now surrounded by both ninja females, for the relief of a recently-recovered Sasuke (who, thanks to his family recordings, probably had a good idea of how Naruto's kekkei genkai broke everything they thought they knew too). As much as Kakashi himself would rather ignore the symbols' existence until Naruto learned more about his suit, Sakura's mind was very focused on the challenge of solving their mystery, while Haku seemed to think deciphering them would help her "shishou" (and wasn't it a riot how Naruto's face froze for a sec while his eye twitched every time she called him so).

"But this does not make sense, are you sure you drew this symbol right?" he heard the pink-haired one say, frustrated. "It does not fit the structure from the previous texts!"

"This is just from the scanner screen though, so it may not be following grammatical structures if it is just minimalized descriptions. Like a health bar that only says 'life'," replied the pink-dressed one, ignoring how weird it was to be talking about something biological as one would a videogame.

Nope. Not going there. Think about his books. Icha Icha Paradise. Icha Icha Paradise that apparently would get a visual novel added to the series soon, with great artists and voice actors. Which led people into arguments if visual novels count as books or videogames, since it would be the first Icha Icha official game if so. Speaking of videogames, Naruto's—

"Argh! I give up!" he screamed, hands in the air. "Naruto, take off the suit and make some clones, let's help the workers so we can take you to the hospital check out on it sooner!"

"Yes sensei!" the boy jumped to obey, relief clear in his voice as he removed the outer layer of said suit on his way to join him.

That was another reason calling it a suit bloodline limit felt more fitting than an armor one. While the whole thing seemed to be growing out of the inner suit, it could also be brought back and forth from it as if a separate layer. This inner layer was still as protective as Kakashi's jonin vest too, it seemed (just covering the whole body), and also seemed to regenerate from the few damage that did get through with enough rest.

And, unlike the outer layer, wearing only the inner one did not seem to get in the way of his chakra control. It was not impossible when wearing it, or at least for now, but… well, let's just say that Naruto's worsening attempts to tree-walk with the outer layer active were becoming as frustrating to the boy as the muscle fibers recovered as it was hilarious to him.

In other words, it was a bit useful right now, with its protections and those projectiles, but it really did not fit the boy.
Not at the moment, but he was sure to grow into it. Just as Kakashi alluded to Sasuke during the Bell Test Naruto may be the best in their team. He may currently not be that skilled, but he had more than proved himself apt at adapting and improvising.

"Watch out!" he heard, and looked to the side just in time to see a bunch of Narutos trying to help another to balance the cement bags before it fell backwards and dropped them on top of the civilians.

He reassessed his thoughs. Maybe, just maybe, Naruto was too unpredictable to even predict his potential…

IIIII

As Haku watched her new teacher be reprimanded by his pink-haired teammate, Sakura, for trying to show off, and then that it not being trying to show off made it even worse, she used her natural control over water to mix some cement herself with a much easier time than the civilians around her.

Some would wonder if that scene would have made her question her choices… but it was the opposite. Even as he was doing things wrong and accused of goofing around he kept a smile in his face. He had the potential to be a good fighter, in her eyes at least, but he was not just a fighter. He was…

He was kind of a dork, she guessed. Oh she could see a few glimpses of darkness and hurt inside his eyes, but despite that none of it reached his smile, his interactions with these people that enjoyed his company just as much even while grumbling about how bad he was as a builder.

And then the grandson of the bridge builder she and her Zabuza-sama were hired to kill arrived with lunch for everyone, and while she was sure they once disliked each other they both had happy smiles of mutual respect and, in the boy's eyes, clear admiration.

This is what she wanted. She already knew how to be a ninja. Now she wanted to learn how to be a person.

…and he was not bad on the eyes either, if she was being honest. Oh sure, she would definitely agree with Sakura that the other boy was more handsome overall, but Naruto's looks had a mix of delicate and ruggedness that was more to her tastes.

Especially in that formfitting bodysuit.

What could she say, she may have seen Zabuza as a father and thus family, but she never denied that their time together shifted her preferences more to his body shape.

A body shape that Naruto was clearly going to grow close to, and that suit hid zero of it. It was as if that ass was covered by nothing at all.

Nothing. At. Al—

"Hey," a rather painful pinch on her arm brough her back to reality and to the face of an annoyed Sakura. "If I can't use this time to ogle shirtless a Sasuke, then you can't use it to ogle the idiot either," she whispered angrily.

Haku sighed at that, but it was a fair point. So she used her control over the water in the cement mix to move it to the several empty buckets for the actual builders.

She did not even try to hide her amusement at how it took some seconds for the other girl to leave, and even huffing angrily to herself about being distracted by "stupid sexy Naruto".

IIIII

It was… an awkward departure for Haku.

She was not just going to a Hidden Village for the first time with Team 7 – and not even Mist but Konoha, but she was fully aware that had her and her Zabuza-sama not been defeated every one of those grateful faces would have still been under the iron grip of the greedy midget that had hired them.

Yet… they were not angry at her. They did not just forgive her, them, but they were grateful that she helped them afterwards.

So she just stood there with the team sensei, waving goodbye to the villagers while Naruto hugged and cried together with young Inari.

Still in that jumpsuit.

Apparently whenever the suit would be summoned it would be in a burst of energy that destroys every loose article of clothing. Even the loose tips of his headband were a bit battered.

That included his underwear.

And Naruto favored boxers. Loose boxers.

So now Haku would be going to a hidden village for the first time together with what she was pretty sure was her first crush, that apparently destroyed every article of clothing he was carrying trying to train not to… do just that. Meaning that he would be wearing that jumpsuit all the way, and only that jumpsuit.

She did her best to ignore both him and the angry envious glares of the pink-haired girl behind her about which boy was dressed like that. No, she was not feeling lucky at the moment.

…

Ok, maybe a little bit.

IIIII

Sarutobi Hiruzen, also known as "The Professor", was the Third Hokage.

He was supposed to be retired, but with his successor's death with no proper person to take the reigns afterwards (the second candidate being his wife, who died with him, and Hiruzen's student who did not take losing the position well) he was forced to take the position once more.

He had been forced to make many questionable decisions. Many of those he asked himself many times if he really made the right choice

The incident with the Hyuga heiress at least proved to him that hiding Naruto's true heritage had not been a mistake. Even discounting how Iwa may have gone after him for his actions of his father during the war, his mother's family the Uzumaki were considered one of the most valuable bloodlines due to how powerful their varied bloodline limits were.

He very much probably should have given the boy a different family name, but he was a sentimental of fool after all.

However, for as varied as the Uzumaki's Bloodline Limits may have been, there had been a consistency to them. Even besides their natural skill with seals and above the ordinary stamina and chakra capacity. Creating chains be them solid chakra or made out of seals, detecting chakra, detecting negative thoughts, healing someone when bitten even.

The reports Kakashi made did not fit with the pattern. At all.

A skintight jumpsuit as resistance as a jonin flak vest and self-regenerating. And when fully "healed" it could grow what seemed to be an armor, but that also had artificial muscles that improved the user's body, a helmet that let Naruto walk underwater with no issues and both connect with current communicators and analyze anything it observed for long enough. And that was its current abilities, since the report mentioned throwing explosive balls of chakra and compressing and rolling around as a sphere before Naruto was almost killed and it self-destructed, being still regrowing.

"…Kakashi,"

"Yes, Hokage-sama?"

"What the fuck."

"Agreed, Hokage-sama," said jonin nodded, ignoring the surprised look of… every genin there but Naruto, really, who had a smug smile at his cursing instead.

Well, time to kill that. "As soon as you and your team are dismissed, you will take both of the boys to the hospital for a proper checkup. Including about this… 'suit' kekkei genkai."

"Agreed, Hokage-sama," was the lazy reply. It was not a surprise, after all the both of them almost died.

Naruto's horrified face was not a surprise either, but it was extremely entertaining.

"Now, let us discuss what to do with our new friend," he then turned to Haku with what he hoped was a calming smile. "Would I be right in believing you wish to join us, but only in order to be closer to Naruto-kun?"

"Yes, Hokage-sama," the girl replied, bowing respectfully. "I wish to spend as much as you would allow near Naruto-shishou," Hiruzen smirked at the boy's groan at the title. "So I would like to request to join his team, and to be able to move together with him."

"What?"

"Naruto, Sakura," Kakashi admonished the two, but Hiruzen could feel the mirth in his voice.
Not like he could judge, he was doing his best not to start laughing.

"Unfortunately, I cannot allow a girl your age to share the apartment of an unrelated boy. Especially since I know for a fact Naruto-kun only has a small bed and no real space for a second. But I can try to set you in an apartment close to his."

The girl nodded at that. "Thank you, Hokage-sama."

Hiruzen had to resist the urge to wince, imagining such a polite girl corrupted by being around the prankster – and worse, learning from him. As if his grandson Konohamaru had not been enough…

"And about joining his team, we limit our rookie genin teams to three genin and one jonin teacher, and Team 7 is not experienced enough to change this formation. However, said jonin teacher can request help from a chunin or another jonin in their training. If you can convince Kakashi to, and is evaluated as at least a chunin – which from the report will be easy for you, you can join them for training sessions and be as an observer while they do missions. You will still need to take missions on your own, though."

Haku nodded at that, before bowing. "I deeply appreciate this, Hokage-sama."

He waved his hand, and one of his ANBU joined them. "Please guide miss Haku for an evaluation, and if approved try to accommodate her near Naruto-kun's apartment," he ordered. "Team 7, you are dismissed."

As the team left, Naruto himself losing all energy at their next destination, another ANBU approached their esteemed leader. "Hokage-sama, are you sure it is wise to let this girl live close to Uzumaki Naruto?"

"Hmm… wise you ask, Cat?" he repeated. "No, not at all."

Well, he joked to himself about how Naruto would ruin her politeness and all that, but… it was clear to him that the girl was somewhat broken. That the loss of her first mentor, that from the report she thought of as her real father in all but blood, almost made her lose all will to live and then projecting it on Naruto was her way to cope.

It was clear to him that she would be more Naruto's bodyguard than a ninja of Konoha…

"But I'm fine with that."

As much as he knew it was a wrong way to think of it, he was not kidding when he said he thought of the blond as another godson. He was a very lonely child, some of it Hiruzen's fault. Even if she distanced herself from him, she would still keep herself close. She would be there for him, to protect him, to help him.

And maybe he would help her to mend, in his own way.

After all, as much as he complained about Konohamaru's new behavior thanks to Naruto's influence he was much happier and hard-working. Even Ebisu respected him for that, even if he disapproved of the methods.

IIIII

"Are you for real, Naruto?" Sakura rolled her eyes.

Naruto just glared at her. Which… she had no idea what to think about, since before he would do anything but glare at her.
Was she relieved? Insulted?

She decided to focus on how ridiculous he was being.

"It was just drawing some blood from you with and without your crazy suit, three times. And then turn back and forth while a machine scanned you, something you did all the time while training in Wave."

"Ok Sakura-chan. First? Needles. On the skin. They hurt!"

That only got him an eyeroll.

"Seriously, and what happens if it… breaks in there or something?"

"That doesn't—"

"A cousin once told me it happened to his father, and they cat to cut his arm open to take it out," Sasuke entered the conversation. "I think he was just messing with me, but I don't want to risk finding out."

"Are you seriously taking his side on this, Sasuke-kun?" she asked, incredulous. "You went there yourself because of taking so many needles!"

"Yeah, me and Naruto," Sasuke nodded. "And what do they do? They stick more needles on us. Even if I had no problem with them before, we are still a bit traumatized."

"Yeah, respect the trauma!" Naruto agreed, and the two fistbumped.

Kakashi giggled in his book. Sakura felt her eye twitch.

"Second, since it was a complete checkup for any changes that may have been caused to his blood in both his normal, with the undersuit and the full suit, he had to give them more blood than usual," Kakashi took over for Naruto. "Even if it is still safe that was still a dizzying and uncomfortable amount of blood to lose at once, pretty sure that was close to the amount of a blood donation. Just because a blood pill helps it is still not comfortable, and he could only take one when they were done."

Sakura sighed, but if their sensei was saying so she had no choice but to agree there. He knew best how bleeding and blood pills worked, after all—

And now she had to think about people bleeding and blood pills. Lovely;

"Besides, you are forgetting that he had a female doctor," their teacher pointed out.

Sakura looked at him, confused. "Uhm… and?"

"And he did not get a chance to go home yet."

"…I don't follow."

Kakashi sighed. "Sakura, what is he wearing?"

"An orange bodysuit that somehow does not look like a monstrosity."

"Oi!"

"Very good," Kakashi nodded at her. "And besides that?"

Sakura opened her mouth.

Sakura closed her mouth.

Sakura did the amazing feat of paling and blushing at the same time.

"…why didn't we get him some new clothes in Wave again?"

"Because we were trying to learn how the suit works, and until then we would just destroy some poor person's clothes." Kakashi wisely did not mention that they could have just taken the clothes off during training. Mainly because he unwisely forgot about the possibility while there.

He is a genius ninja. He also reads porn in public. Don't expect consistency from him outside the battlefield.

"Screw you guys, I'm going to Ichiraku. You coming, bastard?"

"Hmm, why not," Sasuke shrugged.

"Wait what?" Sakura balked, running to reach them. "You are going there dressed like this?"

"I've been dressed like this for weeks, Sakura-chan," he pointed out. "You even forgot about it until now!"

"Yes, but I've been seeing you in them all these weeks. I'm desensitized! You can't just go in public like that here!"

"I've been too long without Ichiraku Ramen to go home before eating it again," he growled. "…and besides, Kakashi-sensei said one of his jonin friends, and at least one of his genin, are dressed in a green one all the time," he shrugged. "No one will really mind."

"Not the rebuttal you think it is," Kakashi said casually so only Sakura heard him, but still followed the boys.

With a loud groan of frustration… Sakura followed too. "Don't blame me if we are kicked out!"

"I won't!"

IIIII

Treatment of Uzumaki Naruto is reserved to only the top level doctors of Konoha.

He did not know that. Just as much as he did not know why, or how valuable his blood was. Even finding out about being a jinchuuriki was a recent event.

Everything involving Uzumaki Naruto's family, on both sides, was highly confidential. After all, one was a past Hokage, and the other was an Uzumaki.

Anything involving the Uzumaki was considered crazy. Not just because all three other famous ones, Mito and Tsunade Senju and his mother Kushina, were high level kunoichis, but because it was a main bloodline of a whole hidden village that was allied to Konoha until its downfall. A family that was legendary as the greatest allies one you have… and the most terrible enemies.

So it was with great surprise that, as the doctor reviewed all the data, she figured out that this incredibly impossible bloodline was coming… from the father's side.

IIIII

A small piece of awareness was pinged.

Not enough to "wake him up" as it was, but enough to draw a (figuratively) sleepy eye to it.

Could it be? Could he dare hope?

It should be impossible. She would have been too old for any human being, and even the changes that she went through would not have changed that… right?

Yet… he dared hope. As much as it should be impossible, both for him to hope and for her to fulfill them.

The message was unfocused. Not aimed at him it lost some of its power, but was still…

Intelligible was a very generous wording. It was gibberish, a wild mash of Federation and Chozo letters, making up words that did not exist in ways that did not follow any grammatical structure he had recorded. It was either a brand new dialect, or something very corrupted.

Yet, while it held no known structure it held some. While the words did not seem to exist, they were consistent.

Maybe, just maybe…

He sent a "ping" back. Just a location. Just an "I am here".

And went back to sleep.

But not fully. Not anymore.

One figurative eye was kept open.

Waiting.

Hoping.

IIIII

Fun fact, in the Metroid manga (official at least in Japan, since scenes of it are used as endings, but were removed in outside releases), on chapter 13 (Hunter) Samus' sleeve is destroyed as she summon just the canon, then after firing it and we see her in full armor her cloak is clearly destroyed.
As this is the only canon point I am aware of she is not wearing either the Zero Suit or something skintight enough it would be under it with no issues, plus how from we see her summoning the Power Suit as energy from the Zero Suit in cutscenes, I am assuming that anything not skintight enough to be under the Zero Suit would be destroyed by the energy surge.

Couple the fact Naruto uses boxers and how the idea of Naruto in a Zero Suit reminded me of the Stupid Sexy Flanders joke, and Horny Haku was born.
Plus a cameo by Horny Sakura (whose most memorable appearance for me was complaining with a nosebleed about how even if Naruto's Reverse Harem jutsu worked on her did not mean it would on Kaguya… who was right away punched in the face by Naruto with no attempt to dodge).

Anyways.

At old versions of this chapter I was having either Kakashi giving a very detailed description of the (current) full Power (Fusion) Suit and its abilities, or Naruto using said abilities in a training session. Both after the suit is fully recovered from the explosion.

This time, I decided to make the suit take longer to recover, even with Naruto's increased regeneration. And this let me show it as it regrows over the Zero Suit (it was shown to at least regenerate damages slowly over time in the Samus and Joey manga, which happens between Super and Fusion so she does not even have the life-saving Metroid CRISP from the later yet).

With this extra recovery time Naruto will be able to learn more naturally all the skills and limitations of the suit. For example, I hope I made it clear that he will have a harder time using chakra externally when using the full suit – not completely, but don't expect him to create an army of Power Suit'ed clones for example.

And I also hope I made clear that, despite it being a Bloodline Limit, the fact it was an engineered biotech one the Chozo made for Samus means it kinda breaks all the rules the people of Naruto's world know about them (and the minds of those that dwelve too deep trying to figure it out (not exclusive to them according to the Prime games though)), including having better compatibility with their tech than their actual tech. On the other hand, the generations having passed means the data that was genetically passed forward cannot be accessed. If it is even actual data, as pointed out at the end it was very corrupted so it may be gibberish even after Naruto can access it.

And I will not debate about the real-world existence or not of genetic memory, epigenetics and the like. We are talking about Chozo tech that is biologically bound to Samus – which was a plot point right at the start of Fusion, that in this story was passed forwards to Naruto. They are real here.

Currently useable suit skills:
Improved strength, improved speed, improved durability, underwater breathing, Scan Visor, communicator.
