Son of the Sea and the Whirling Tides

Prologue: The Deities meet

Two men met on a craggy outcrop of land facing the sea, the waves rose and broke against the rocks of the cliff face with less a roar and more a muted hiss as if the very waters themselves were trying to be silent.

With dark hair and piercing green eyes clad in a pair of grey fishing shorts and a light green and light blue Hawaiian shirt with island prints upon it. He carried himself with the air of a deep sea fisher man, a long-time mariner, and naval man pacing up and down along the cliff bottom in clear distress.

While his companion with rustic blond hair and startling multi-coloured ripple pattern eyes clad in a black cloak over a set of lime green robes and carrying an elegant cane, a white and green striped bowl shaped hat completed his appearance as he sat on a rock under the cliff face unperturbed.

Poseidon Greek God of the Sea and a high ranking member of the Olympian council famed like many of his kin and his brothers in particular for his affairs with mortals resulting in demi-god children of two worlds had fallen of the wagon again so to speak. He'd met and fallen in love with a woman who so resembled the sea he loved so much. Breaking the oath he and his Brothers had sworn fifty years ago to never again have to powerful Demi-gods changing the course of history.

Kami the Creator, God of all Ninja and one of the many gods of the Ninja Continent who only ever fell in love with a mortal woman once (practically a virgin by Olympian standards) an Uzumaki siring the first and only demi-kami who revolutionised the way of the Ninja due to his eyes of god (the eyes of Kami he inherited) the descendants of his son would go on to affect and change the Elemental Lands for good and for bad for generations.

Kami glances down at the crib beside him fashioned out of coral and stylised with carvings of starfish and dolphins inset with glowing crystal shards of green, blue, purple, red, yellow and orange. Inside carefully wrapped in a Dark blue blanket the tiny form of a new born baby slept lulled to sleep by the ebb and flow of the vary tides themselves. Half God Half Mortal but more than that possessing the bloodline of the Uzumaki direct descendants of Kami and born with an active Dojutsu the Kami no Gan more commonly referred to as Rinnegan! Not that having freaky if cool eyes would be much of a consolation considering his mother died in childbirth.

It wasn't like there wasn't president for this kind of thing gods in general had a long history of falling in love with mortals deemed of limits or under the protection of other Gods and had caused many of man-kinds bloodiest wars; yet never before had a mortal child of god been born that combined the powers of two different deities from two different pantheons.

They could both tell that the boy would grow up to be powerful perhaps more powerful than any demi-God who had gone before; Heracles, Theseus and Perseus, he could surpass them all he could even become greater thanKyūseishu the Rikudo Sennin and son of Kami. And he was already considered to powerful just by been fathered by one of the main three. If his family found out he had the powers of a foreign God…

"If my fellow Olympians learn of his existence they will demand his death" Poseidon declares morosely stopping his pacing to reach out to his son stopping short of touching him.

"I would never allow that" Kami declares succinctly "I may have only fell in love with the one mortal woman in my life-time but I've always held a soft spot for the Uzumaki clan" he observes the sleeping babe knowing full well that behind it's closed eye-lids a pair of whirlpools hid ready to ensnare anyone who locks eyes with his tiny sea Green iris's.

"Even if our links are tenuous at best I won't abandon my Great Great Great Great Great Great Great…Great…Great Great Grandson" he finishes eventually "after all blood is thicker than wat…oh sorry I didn't think that through"

Poseidon can't help but let out a chuckle at the antics of his father in law? He had to be the most eccentric God the Lord of the Seas had ever met he'd spent significant time hanging out with Apollo and Hermes at the same time before.

"I have already broken the oath that was erected to prevent the great prophecy from been fulfilled…I cannot risk raising him if he is discovered it could begin a new war of the gods" Poseidon states sadly. Omitting the fat that his wife Amphitrie who while hardly as bad as Hera been the Goddess of Marriage still frowned upon his…indiscretions, and immortal son Triton tended to view his mortal Children as insults to their status as Lady and Prince of the seas.

Kami scowls resting his head on his cane "I hate Prophecies...predetermined fate...Destiny" he clicks his fingers absently "that reminds me must remember to kill of the Great Toad Sage, damn decrepid ancient old croaker causes my descendants nothing but trouble with his imbisilic ramblings"

Poseidon couldn't even begin to comprehend his companions vendetta about an apparantly elderly amphibian with the gift of future sight but could at least understand his feeling on the matter having felt like strangling each of the Three Fates himself not that it would have had any affect Damned immortal crones.

Kami sighs despondently "Well I can't raise him directly myself I had to get my son to enact the changes I wanted to improve the Elemental Lands because I couldn't directly interfere…but that's not to say I'm powerless" he smirks "Yami and Shinigami both know when to look the other way so to speak, Lady Rakki owes me a favour for dealing with the fallout of her obsession with the kyuubi brat…and I am due a few 'acts of god' to even out my yearly quota"

Poseidon smiles warmly running his hand down his son's face gently and stroking his little hand. "you can find him a family, someone who'll give him the love, care and affection Shiina would have wanted him to have?" he asks hopefully picking up his son into his arms.

Kami smiles weakly "I can't promise he'll lead a safe life, while monsters from your world rarely venture here, my Ninja can see, fight and slay them" the statement delivered with the typical 'my Mortals are better than yours' attitude adopted by all foreign gods. "but if he stays here he must become a Ninja, a Shinobi, the life of a Ninja is hard and dangerous but quite rewarding…I think I have the perfect mother figure in mind for the boy she's lost so much already and needs something to anchor herself to the world…pun not intended but appropriate under the circumstances"

"She will be there for him when he needs her? She will never abandon him or forget her duty to saty by his side and protect him?" Poseidon half asks/half demands holding his son defensively in his arms.

Kami nods his head slowly "so I swear on the silver sands of Hueco Mundo she will never abandon her adopted son, I will not betray you…if you do not betray me"

Poseidon reluctantly lets go of his son handing him to Kami "I swear on the River Styx if she harms him no body of natural water will be safe for her to enter ever again, I will not betray you as long as you do not betray me and my son" he glances down at his first Mortal child in decades a tear trickling down his cheek "good bye Perseus" he whispers "never forget I love you for now and forever" his form wavers and turns to water vapour dispersing back into the sea as it's Lord returns to his undersea palace and his duties.

The baby Perseus opens his sea green rippled eyes and begins to cry as the crashing waves and spray of the sea seems to grow louder as though this whole time the gods conversed the world was put on mute that has finally slipped. He begins to cry as though sensing his fathers loss.

Kami sweat drops as he makes awkward shushing motions. And they wonder why Gods never raise their mortal children he thinks with the same tired bitterness of every single father in the world at least Immortal children are either born of age or have immortality conferred upon them when they've outgrown the nappy changing and crying stage.

He raised his cane and opened a hole in reality to travel to their destination through.

Yes young Perseus Uzumaki you could be the best thing that could happen to the girl right now, raising a kids got to be a step up from joining Root Anbu or death come to that.

AN:

This is a Percy Jackson/Naruto crossover and while I like the stories where Naruto's a demi-god I don't think realistically it's likely that the gods slip of to have affairs and interfere in the ninja world (it has it's own gods who wouldn't take kindly to loosing their child of prophecy) I'm also inspired by the lack of powerful Percy fics. Naruto doesn't really need powering up anymore (he's got the Kyuubi and yet I've never seen a PJ/N crossover where he uses his inner demon).

Timeline: Perseus is the same age as in the book series and was born 2 years after the Kyuubi attack making him 2 years younger then Naruto and the rookie 9.

Perseus won't suddenly show up start kicking ass and taking names and get all the girls (including filler arc babes) Naruto will still get to be a mortal (or demonic if you count him as a demon host) hero of the Elemental Lands (Wave country, Snow/Spring country, Vegtable Country...ect) Speaking of the elemental lands (or Ninja Continent as they're referred to by Greeks) there not a separate world from Earth but exist in the same world but separated by a divine Genjutsu so it's similar to the sea of monsters. The Ninja Gods prevent any of their subjects from leaving and/or interfearing with the greeks and other Deities and the Greek gods and Gods of other lands prevent their subjects from doing the same. An Invasion by foreign Demi-gods or even mortals would be considered an act of war! And the various Deities have for many centuries long since strived for peace (following the unfortunate and so called holy wars of the crusades in the 11th, 12th and 13th centuries.

Rather than one Sally Jackson Poseidon instead fell in love with an Uzumaki woman (OC who died in childbirth.) Famed for Fuinjustu and swords mastery: who's to say Percy gets his skill with a sword from his dad? Poseidon wields a Trident afterall! this occurs on an island near the edge of Kami's kingdom.

As stated above Gods have a history of chasing hot babes who are of limits even so this is the first time (in this world) a greek demi-God is born with powers from another type of deity other than Greek alongside their Greek God powers. this naturally makes Perseus more powerful than any previous Demi-god but still no match for a full God unless their handicapped like when Percy fights ares and several titans in the book series, had they gone all out or released their 'true' form they'd have squashed him like a bug, (sad but true.) Of course this will make him a significant threat in the eyes of the gods (more so than he was percieved to be as percy Jackson) Ironic though it is that the gods had forwarned knowledge that Luke would join Kronus and try to bring about their destruction and did nothing while Percy may or may not be destined to either save or destroyOlympus and yet tried repeatedly to kill or neutralyse him...get your priorities soughted out!

Nagata/Pein has also got the Rinnegon which he awoke his during his childhood (possibly with help from Tobi) while Perseus on the other hand was born with active Rinnegan eyes. A blessing from Kami or pehaps fate marking him for future note? Perseus is descended from Kami on his mothers side while pein is a pureblooded Uzumaki (both parents are Uzumaki like in the Uchiha and Hyuugi clans, intermarrige to maintain a strong bloodline) neither of their eyes however are as powerful as Kami's or even the original Rinnegan weilded by Kami's son the Sage of the sixth paths, and their is no real difference between their Dojutsu beside the colouration.

Perseus isn't two thirds god like Gilgamesh (although that would be a cool idea for another story) Kami's divine blood has been watered down by mortal blood for several centuries of generations and while the Rinnegan can still be awoken by any of Uzumaki heritage (precise details of how to awaken it aren't known, and Kami's other descendants have been known to obtain it artificially possibly by combing Senju and Uchiha blood) it has been seen rarely since the days of the Rikkudo Sennin falling into legend and has certainly never appeared in two people at the same time before. (foreshadowing an even greater uphevil than any before...) it is also possible that Poseidon's divine blood forcibly awoke the bloodline within Perseus, these been untested circumstances.

Perseus's Rinnegan will have all the powers of Pein's plus whatever other Ninja techniques and styles he picks up: I have plans for what to teach him and how powerful Ninja wise he will be, bearing in mind Kakashi was jonin by the age Naruto graduated as a Genin and as Kakashi once said "there are people stronger than me but younger than you" refering to his 'TWELVE year old charges...and yet all the really tough super powerful genius ninja are already in their teens or fully mature, Naruto's Generation suck graduating way behind the older generation and other than Shika failing to reach Chunin and Jonin as fast as the likes of Itachi. I plan for Perseus to appear two years younger then the Rookie 9 show up kick ass and leave everyone feeling inadequate because they got their asses handed to them by an even little kid! (Haku shouldn't have been two or three years older than Naruto he should have been two or three years younger to really mess with their heads.)

The Rinnegan abilites paths and all that will remain the same for the most part both Pein and Perseus will lose the bringing people back from the dead like it's nothing ability though. bringing people back from the dead is to powerful and for my mind falls under the Shinigami's domain and for that matter; Why didn't Pein ever bring Yahiko back to life? His body was well preserved and according to current manga a part of the plan was for him to bring the original Madara back to life and he's been dead for what over half a century so it's not like theirs a time limit attached to how long people are dead before he can't bring them back! So my new theory on that power is that it can only heal/regenerate bodies although it can do so from even fatal wounds so long as they haven't died yet. And likewise if a dead body is been used as a puppet/relay (the Six Paths of Pain for example) they can be healed of all damage but aren't actully brought back to life, However for when you really need an implausable ressurection the outer path technigue enables you to restore life to the newly departed and bring them back to life and depending on how many you try to bring back it affect you thus: save-1 person life-span halved, save-2-4 people life-span reduced to around a year if that. Save 5 or 10 and your lucky to get a few days to a week of lifespan left to live. any more than that and you drop dead in exchange. However so long as you have the chakra reseves say roughly equal to a Jinchuriki's full reserves (which Pein had even after loosing all six of his paths and single handedly destroying an entire village you can bring practically a whole village back to life at the cost of immedietly dropping dead after the Jutsu finishes.
