This is a Naruto & Percy Jackson Crossover Fanfiction only.
After a thousand years, and many adventures, they had children, married loving and caring wives, and they eventually grew old, but unlike everyone else, thanks to or since Haguromo had given both Sasuke and Naruto his chakra and skills he had as the sage of the six paths, their bodies changed and even obtained a perfected version of the Otsutsuki Doujutsu.
To Naruto it was amazing, to Sasuke it was annoying since Haguromo pretty much told them as the reincarnation of his sons, but he still considered them his sons, and after seeing their memories, he came to realize what really had happened and what drove the two brothers apart. He admitted that he made a mistake in putting the benefit of the world ahead of what his own sons deserved or needed and doing what he did was his way to apologize to both of them.
Naruto was quick to forgive him, but Sasuke feeling angry and frustrated his only remark was a little too little and too late. This caused Naruto to hit Sasuke in the back of the head and push him to bow to the man who still wanted to treat them as his sons, which made Orochimaru honestly begin to laugh and upon living with them he soon came to realize that the most precious thing in life was to have a place that he could consider family, living with a loving family made a place an actual home.
"You two say that you are friends and used to be academy rivals and all that, but to me and Orochimaru it is quite clear you both argue and fight each other like you are brothers. Now wash your hands and you two help me set the table, or the food we prepared is going to get cold."
As both Naruto and Sasuke did as their father told them, the only strange thing was that there was a woman there helping them but she oddly seemed like a female version of Orochimaru, as they set the last cup on the table Orochimaru simply said that their home needed a woman's touch, so he made a clone of himself and used the technique Naruto used to make that clone into a woman, "Throughout my life, I spent jumping from one body to another so many times and spent so many years as a woman, it really is not that weird to me, you should be the least one to complain Naruto, you invented the Sexy Jutsu Technique in the first place. Now come on Sasuke-kun, go with my clone and help her carry that pot from the kitchen, you aren't going to let her carry something that heavy by herself or are you?"
It took them thousands of years but in the end, they had little to do, they had watched as all the people they ever loved grow old and died, and training was just a way for the two friends to spend some time being able to do something, anything to keep them from going insane until they found something they never once realized still existed.
The ruins of the village were hidden in the eddy, or as Naruto once knew it the original village of his clan. The village had literally nothing worthwhile in it, even the bodies of the dead were not buried since they never found a graveyard, they did, however, find a strange monument in remembrance of the village until Naruto walked into the village where the village leader would have lived, and that is when he started to notice that the walls had a lot of lines and letters written on them.
Most people would have called it a heartless example of vandalism, Orochimaru called it a bunch of punks doing disrespectful shit for giggles, but Naruto knew better, and as he began to write down all the lines and letters on a single sheet of paper, he realized that it was a letter, a distinct letter to any surviving Uzumaki, the letter gave them distinct instructions of how to create a seal that when activated would have allowed most of the village to escape the destruction of their village, but even Naruto called it nuts because the place where they would end up is an alternative universe, a different version of their own universe.
Orochimaru having nothing better to do, in fact, did as the letter described and using his own knowledge about seals worked long hours with the two friends till after a solid month they actually managed to finish making the seal, "Well on one side we got little to lose, we are getting up in years, and everyone that we ever cared about is long gone, so might as well take the plunge and see this as our last adventure into the unknown, as both you and I are pretty damn old, so come on Sasuke, let's go. Orochimaru having used a white Zetsu, is still pretty much going to be young forever, but we are not so lucky."
Orochimaru however did tell the two of them that he did in fact offer them a chance to go through the same thing that he used for himself, but they both refused his offer, if he remains young forever and they are old, they only got themselves to blame. The one problem was trying to find what sort of chakra they needed to activate the seal until Sasuke mentioned that maybe used Nature Chakra since more than likely the person who left the instructions had been a sage. When asked why he thought of that he mentioned that it was in places where he would have to literally stand on walls, so that gave Sasuke the idea that it was more than likely a person who knew Toad Sage Arts.
Naruto being a kind and caring friend simply called bullshit on the idea and said that Sasuke only is saying that because he was an Uzumaki and a person who is a Toad Sumoner who mastered the sage arts on Mount Myoboku. To which Orochimaru that the slugs and Snakes also had sages so that doesn't prove a damn thing. Tsunade and much to his eternal chagrin Jiraiya were sages. Seeing that this was getting them nowhere and fast, they all decided to harness as much Nature Chakra as they could and pumped it into the seal they had placed on the floor of the building they had been staying in since they arrived at the ruins of the village.
When the seal activated it felt like this was a giant version of an explosive tag seal that someone drew for shit and giggles all over the walls, because the first they felt was a massive explosion of energy and then they found themselves exactly the same place where they had been, except there was no seal on the floor and the place looked exactly as broken when they first found it. Sasuke could only attribute this to two things, either the seal sent them back in time to a time after the village was destroyed or the seal trapped them all forever in a place sealed in time set after the destruction of the village.
As the three of them left the ruins they began to go to a place they all knew fairly well to get an orientation of the land, it was a particularly famous place that both Naruto and Sasuke knew from their previous life, they fought there several times, it was called the Valley of the End, and it was a place where apparently two massive statues of their previous lives were constructed to commemorate the event that happened there. This would also give them an idea of when in time they were since if the statues were present it means they were definitely in what they consider the past, since the last time they fought their battle ended up destroying both of the statues.
They quickly made it through the land of wave and found themselves getting closer to the place by following the rivers that feed and go through the valley, it wasn't hard for them to get a feel of the place even if a few things were making Sasuke worry since he could somehow feel that not everything is as he remembers, it was a subtle feeling almost like a sensation that sent a vibration through his skin, his tailed beast was quite vocal about her dislike of the taste and smell of the area, something didn't feel right to her and it made her think they were not in the same reality she was aware of, being ten tails it was something that allowed her to be in touch with every aspect of reality, but something in the place they were was making her feel like something was crawling on her scales.
As they finally reached the place Sasuke could remember the first time they fought in this place and not the time in their previous lives. He was honestly trying to leave Konoha to get help from Orochimaru who apparently promised to help him get stronger to avenge his clan, which after everything that happened and what he later learned he now considers one of the events of his life that he will never be able to live down, it was truly a stupid and insane notion that embarrasses him from the stupidity even in the present, not that he would ever admit it.
"Honestly Naruto being back in this valley is not making me remember that many great decisions of mine, I am still shocked that Itachi, the person who I thought killed our parents, saved me from being possessed and turned into a sock puppet of Orochimaru, no offense, but having that cursed seal might give me power but having a piece of your soul inside it ready to possess me at any moment, sucked."
Orochimaru looked at Sasuke and he began to nod his head, "In my defense before I learned of the white Zetsu army, I honestly had no other means of escaping the threat of death, it might be a crappy thing, but when you think of it that to me it was a matter of survival, what choice did I have? But you have to admit that the power that the cursed seal as you could use higher levels of it was amazing, I am still trying to perfect that actually, without the body stealing aspect since I don't need to do that anymore. But if I have to be honest with you, I found that you and Naruto here are not what I call entirely human, I did an analysis on your blood and it was you guys have something other than human mixed in your DNA, that is what I can tell from the tests."
He began to laugh as he said this, "Honestly Naruto, Sasuke, once when I was looking for Tsunade to try and fix my arms, I ended up pretending to be a woman and talking with Jiraiya of all people, and when he was drunk he told me something really nuts, that Hiruzen actually told me that Naruto is the actual son of Poseidon, and you Sasuke is the son of Zeus. Greek Gods, crazy I know."
Naruto was quiet as he walked toward the place where they fought, "When I became Hokage, I learned the truth, apparently the Greek King and Queen of the gods, decided to live as humans and turn off their godly powers to supposedly repair their marriages, Poseidon and his wife did the same damn thing, Zeus and Hera took the names of Fugaku and Mikoto, and Poseidon and Amphitrite took the names of Minato and Kushina. So we are technically Demigods."
As Naruto said this he looked down and saw something that was shocking as they saw the badly beaten bodies of their young selves, and he immediately began to try and help the younger version of himself Sasuke did the same thing as he did and helped the younger version of himself barely keeping them alive since they simply had no medical supplies to actually do much more.
They had to get them healthy enough so these two could make a decision about whether or not they would agree to the next part since it would affect their very lives. As the two woke up they were both shocked and scared to see that they were essentially looking at what they would look like if they had grown a lot older than they currently were, the older Naruto's hair was long and white and had a beard that reached past his waist, the older Sasuke had short white hair and a goatee instead of a beard.
They both looked like they had seen hell since their faces had deep scars and wrinkles on them, the only one that strangely enough was freaking them both the hell out was Orochimaru who looked like he was a young adult, no older than one of their academy teachers and had this creepy smile on his face. The younger Naruto was the one that sounded the most freaked out by this and it was no surprise that he was the first to react.
"Ok, we are both grateful that you guys healed us, but what the hell is going on dattebayo, this fucking makes no sense, there is a guy that sort of looks like I do, but is old as shit, and then an older, creepier version of teme here, so what the fuck is going ON HERE!"
Sasuke couldn't help but laugh as he heard the younger version of Naruto react like that, it seems this Naruto is a lot more immature than what he was used to, and using such foul language was unbecoming of a Hokage if he ever saw it. "Look, we just got here from another dimension, using something an old Uzukage left in the ruins of his village, and we found you both beaten and nearly dead, you two aren't completely healed, at most you are conscious, but we need to do something drastic if we want to save your lives. A lot of your organs are either ruined or completely destroyed, we will need to replace them with ours which means we will have to fuse our bodies with yours."
Sasuke looked at Naruto with a scowl frustrated from trying to deal with the fact that the idiot just tried to explain the stuff some would consider fiction as actual medicine. "We know of a seal and technique that will allow us to merge our bodies to make a new complete body, the only thing is, it has never been done on a person before, so we don't know if we would end up with one of us keeping their mind and the other is gone, you end up with our mind, or our mind and soul merge into a new person. We felt that we needed to get you healthy enough so that you decide whether or not you want this done since it will affect your lives."
Sasuke looked at the younger version of himself and was clearly thinking about this rather deeply, as expected, Naruto on the other hand looked at the older version of himself and simply said what is there to think about, either they do it and find out, or they don't and they die, the younger Sasuke simply had only one question to ask, what was in it for their older selves, what would they gain that makes this risk worthwhile.
Sasuke looked at his younger self and began to nod his head, "Clear and the point what is in it for us you ask? we regain our youth, we get a chance to live again and to grow stronger, and probably get to be back with people we both consider to be precious to us. We are old, and by the time we managed to master and gain our strength, we grew older and wiser, but we also had to see everyone we loved or cared about grow old and die. That is why we are willing to risk this, to risk the danger of getting eaten by our minds, and completely disappearing, or us living with the guilt of having done that to you, or we could both literally be dying and becoming completely new people, either way, it is a gamble but the prize is worth the risk."
The younger Naruto hearing that they wanted to grow stronger to be with and clearly protect those they consider precious was all in for it, the younger Sasuke knew better and had a feeling that this was said clearly to get the approval of Naruto, so he had to ask who did his older self consider precious to him? "My wife Sakura, my daughter Sarada, and a young woman who sort of became my mistress by the name of Karin. When I was younger I would never consider marrying Sakura, let's face it, she focused so much on her looks and fashion it was sickening, Kunoichi uses their sex appeal and looks as a true weapon but if they are not skilled or strong enough to use that weapon it is useless, Sakura became much stronger training under the Hokage, and thus truly made me fall in love with her strength, skill, dedication and yes beauty, we had a daughter whom we both love dearly."
"In my dimension, I made the mistake of being consumed by the desire for revenge against those that killed most of my clan, in the end, there were only two of my clan left, and one was the very same brother whom I saw butcher our parents and believed killed most of our clan, I later learned how wrong I was, and learned how I had been manipulated by that backstabbing uncle of ours, Zetsu. As for the Naruto I grew up with he ended up getting married to a nice girl from the Hyuga Clan, Hinata is scary when she is angry, sweet as cotton candy when happy, and clearly Naruto is the guy everyone envies because Hinata also became one of the most beautiful women in the entire village. He had two kids, Boruto who was as impulsive and hyperactive as he was, and Himawari, who was as sweet and as strong as her mother."
Sasuke cleared his mind and looked at the younger version of Naruto before he continued, "I became what my father had been the head of the military police of our village, but Naruto here, achieved his dream and became the Nanadaime Hokage, sadly enough this means his work also caused him to neglect his children quite a bit, so both Boruto and Himawari sort of ended up becoming unofficial members of team Uchiha, and I was sort of their Jounin Instructor as they grew up. It didn't help that my daughter would develop a crush on Boruto and eventually, they would get married. Much to the chagrin of both me and Himawari."
Naruto immediately looked at Sasuke and began to glare at him, "I will have you know I never neglected my wife or children, you know as well as I do, I mastered the use of the shadow clones and unlike any other Hokage in my time, I used my shadow clones to attend meetings, and do all the required paperwork so I could spend time with my family, so stop lying to them. You are still upset that I locked you up in the bathroom and tried to embarrass you when we were students in the academy."
To which Sasuke that in fact, the only embarrassment he ever suffered in the academy is having been the cousin of a person that was routinely called the ultimate wingman, the younger Naruto asked what did he mean by that, "Naruto here locked me up in the bathroom, that is true, but he also transformed to look like me and flirt with Sakura, so in an essence is thanks to that flirting I eventually married my wife, and we had our beautiful daughter, in fact, he did that to most of his classmates and friends and doing so hooked them up together and led to many happy marriages, and they wouldn't have happened without the help of Naruto, the ultimate wingman.
"For instance once while doing a mission with Hinata's team, he snuck into the nearby woods and saw this beautiful young woman doing some training while she looked like she was dancing in the air, almost entirely naked. And this dobe here never once realized that the girl he saw was in fact Hinata practicing her Gentle Fist Kata. You think I am lying merge with him and you will find out if I am."
This made both the younger versions of the friends want to merge with them just to find out if anything they were told is true for various reasons. The younger version of Naruto however was not going to do that without dropping a bombshell of his own, "Well hate to break it to you but the one that Sakura fell in love with is none other than yours truly, in fact, Sasuke here is dating her twin sister named Blossom."
Sasuke called that absolute garbage since the Haruno family only had one daughter and that was Sakura, her father and mother never actually made it that high in the ranks so they dedicated most of their married life to being merchants or escorting merchants. "I wouldn't be so quick to dismiss the possibility Sasuke it seems that the dimension we are in is vastly different from the one we came from, for all we know every ninja has a twin sister or sibling." Orochimaru was the first to scream that shouldn't be real, and that if the sage of the six paths was merciful he would spare him from such horror.
Both friends wondered why did he react like that about this, to which they saw Orochimaru breakdown into hysterical tears, "Having to go to the academy and grow up with Jiraiya was the fucking worse time of my life, having to grow up and attend the academy with two of them, would make my life a fucking living hell, and to expose a twin of mine to that would be inhumane if that sibling was a girl, or do I need to remind you about how your stupid godfather does his research or do I gaki!"
That is when the younger version of Sasuke asked what does he mean by research? to which his older counterpart simply sighed in absolute disappointment and said that Jiraiya wrote the much-hated and often-read book series called Icha Icha, and his research involves whorehouses, peeping at women and doing all sorts of dishonorable and disgusting things. Tsunade when she became Hokage the first mission she ever gave was the absolute destruction of every single copy of the Icha Icha series within Konoha, granted neither Naruto nor Sasuke ever could figure out how in the world Kakashi kept his collection safe, or why nobody ever found Hiruzen's hidden stash.
"It really is not that hard to find it is in a storage seal that Hiruzen has inside his desk drawer, honestly he could take out any book he wanted to read as much of it as he wants and just stick it back in, and people would not even know he was reading that while doing his paperwork." Sasuke had to remember to tell Tsunade about it if she is the current Hokage when they get back to Konoha.
"It actually doesn't matter one damn bit, you know that Jiraiya ended up getting married to Tsunade Senju, hell her sister ended up getting married to Orochimaru, I am honestly shocked that he doesn't know this, does that mean two Orochimaru are going around and one of them is the brother-in-law of Tsunade Senju?"
There was no need to talk any more than they already did, Sasuke just wanted to get this thing over and done with as quickly as possible, and Naruto wanted to check the memories of his younger self to see how much was different in the dimension they now found themselves in. Orochimaru finished the seal while they were talking and thanks to the use of some Nature Chakra and some blood he used to create the cursed seals, both versions of Naruto and Sasuke began to merge together as their flesh melted and turned into a sort of clay and the four of them slowly and quite painfully became two once again.
The two friends immediately looked at themselves seeing that their clothes were nothing more than ripped rags by the end of it until Naruto looked at himself and then he looked at himself and with he screamed in frustration as he realized something, "You have got to be fucking kidding me, we no longer have the arms Tsunade made for us, we are back each having to use our non-dominant arms. Great, you lost your left arm, and I lost my right, again."
Orochimaru looked at them and began to do some analysis techniques, as he finally understood what was going on he smiled, "Well according to this, the DNA in both your arms have merged with your bodies, and that would explain why both of you have Rinnegan in both your eyes.
