Prologue: Regrets

"Some people say the Ends justify the Means, the truth is that the Means justify the End. For is it not better to die a Hero, then to live as a Coward? Can you live with the souls of those you slew on your conscience, I can't, and I haven't slept for nearly four hundred years because of guilt. So learn from my mistakes and live a life without regrets"

Naruto Uzumaki

Lunar Surface, In Orbit around the Elemental Countries Planet. 400 years after the Juubi's defeat.

Solitude, Silence, Rock and Void. For four hundred years those have been Naruto Uzumaki's companions. Four hundred years of isolation, four hundred years of solitude, four hundred years of guilt.

Flashback 400 Years

"You can't" Naruto screams as Kurama explains his and the Bijuus final plan,

I must kit, you are worthy of this power, he is not. Stand proud Naruto Uzumaki, the next Rikudō Sennin Kurama's voice echoes through Naruto's mind and then, searing pain. The Nine Bijuu sick of being hunted and being imprisoned, willingly fuse themselves into Naruto's soul, into his essence, into his heart crystal and his Star Seed. Naruto who had potential to be great exploded in power, color drains from his skin and his hair turns silver. Naruto no longer a mere mortal flings power at the insane Obito, their battle rages without pause, so locked in combat are they that they cannot see the damage they have wrought. The armies fighting around them have been turned to glass by the intense heat. Naruto looking around during a slight pause in the battle notices this fact.

"No, No, NO" Naruto's voice fills with power, more power than it had even had before. Obito shivers as Naruto's eyes turn silver and his pupils turn into slits like when he channeled the power of Kurama. An intense silver aura surrounds Naruto and he jumps into the sky channeling all of his power. He focuses it into a silver orb that blazes with the intensity of a star and shouts "FINAL RETRIBUTION" the orb shoots down and strikes Obito in the face, and then.

White.

The world stills as Naruto's power engulfs it, thousands of years of history gone in a flash. Mountains crumble and oceans boil, great chasms split in the surface of the planet and lava pours forth engulfing everything it can. The backlash blasts Naruto at hypersonic speeds, he quickly passes the distance between the planet and its moon, and then Naruto going nearly Mach 10 slams into the lunar surface, the impact which once would have killed him merely renders him unconscious.

Ten hours later Naruto wakes and looks around in confusion, and then he looks up. And in the silence of the void Naruto screams out his grief, his anger and his solitude. Above him the blazing ruins of his homeworld slowly darken as the atmosphere cools.

Flashback End

Four hundred years of solitude, Naruto took nearly a decade to pull himself back together, he had nothing. In his solitude and loneliness he began to practice his powers, he constructed great wonders using his power and then destroyed them. For the first hundred and fifty years this worked, and then he meditated, tried and succeeded to find a way to generate Sage Chakra while in motion. It took Naruto fifty years of constant experimentation to discover this. Although Naruto had no inkling of the passage of time, he slowly watched his world change back to blue and green, although it looked like home he knew that nothing sentient lived there anymore, he'd devastated his planet in his fury. But the monstrosity that was Obito was also destroyed. 'But did the ends justify the means?' Naruto muses

For the past one hundred and ninety years Naruto had mapped the stars, using his super human abilities he'd constructed a star map of almost unparalleled precision, only some of the best super computers and telescopes could have matched his labor of nearly two hundred years.

Naruto having finished his mighty task looks once more to the stars and sees something made of metal, having nothing to lose he shoots a silver energy flare up to show his location, using his hard earned intellect he fired away from the metal object not towards it.

A/N: Yes, this is a Naruto/Sailor Moon crossover, I know. Not my usual cup of tea, however this idea which was influenced by Ozzallos' 'Heir to the Empire' and uses some of the technology and names mentioned in the story. To all those who think this is going to be a lame story with villains posturing and giving corny speeches, don't worry. This story is actually about a mature Naruto who has suffered now finding redemption. Naruto will help Serenity (Sailor Moon's mother) to build the Silver Millennium from the ground up. He'll influence its designs and some of its laws. He will be Sailor Moon's father, but the romance will be a long way away, you'll see Naruto in several battles and sieges ranging from a simple skirmish to a full blown invasion of a solar system.

Now a little test, to see how many of my loyal readers can guess my intentions, Naruto will be the ruler of one of the planets in the solar system, My question, for a virtual cookie, is which one will it be? Intellectual Mercury, Ardent Venus, Militaristic Mars, Honorable Jupiter, Silent Saturn, Rumbling Uranus, Elegant Neptune or Solitary Pluto?
