Disclaimer: I do not own Naruto or One Piece

READ THE AUTHOR"S NOTE! IT EXPLAINS THINGS THAT ARE CRUCIAL TO THE STORY ABOUT THE RINNEGAN! READ IT!

A/N: There are six paths to the Rinnegan:

Asura Path: User can control a body (Like what Nagato did to control the 6 Peins.)

Human Path: User can extract souls ( When Pein was taking souls of Konoha shinobi before Naruto arrived.)

Animal Path: User can summon various animals (When Pein summons weird three headed dogs, centipedes, and large rhinoceros.)

Naraka Path: User can summon the King of Hell ( The purple/red/black/white monster that Pein summons which pulls people's tongues out.)

Preta Path: User can absorb chakra ( Like when one of the six paths grabs Naruto from behind and attempts to absorb his Senjutsu chakra.)

Deva Path: User can control attraction/repelling forces (Shinra Tensei/Almighty Push, Bansho Tenin/Almighty Pull, Chibaku Tensei/Planetary Devastation, etc...)

A seventh path is the Outer Path, which allows the user to revive the dead and manifest Admantine Chakra Chains. Only Uzumakis can use this Path.

Chapter 1:

"What? What is this?! Nine- Tails, do not finish those hand signs! Don't!" yelled Nagato as the red-head watched one Naruto Uzumaki go through thousands of complicated hand seals. You see, after Naruto defeated the Six Paths that Nagato created, Konan sacrificed herself and gave all of her chakra to her red-haired friend, dying in the process. Back to full health, Nagato had wandered outside of the papery tree his blue-haired childhood friend had created in order to capture the Kyuubi. He fought Naruto hand to hand, and unfortunately for him, they were pretty much equally matched. His blond-haired opponent didn't hesitate or even pause as he looked straight into Nagato's eyes.

"No, I will NOT stop. I will protect my precious people, even if it means going to a whole new world all together! And I'm taking you with me!" he declared, eyes shining with determination. They weren't his usual blue eyes, either. They were blood red, with black rings rippling through the eye, and Naruto's pupils were slitted (a combination of Kyuubi's eyes and a red/black Rinnegan). Naruto's hair was also starting to tinge with the slightest bit of red, just like Nagato's own.

Then, it hit him. Hard. Naruto Uzumaki. That was the name of his target, the jinchuuriki of the Kyuubi. His own name was Nagato. Nagato Uzumaki. They both had the same surname, and were probably the last Uzumakis on the planet, and they may very well have been long-lost cousins twice-removed or something. Kami, they were probably related. What had he been doing? Attacking a family member just for power? Hurting said family member's friends? For what? Nagato realized he could have gone about finding world peace more diplomatically, more peacefully. Sadly, he realized this too late, as Naruto had finished his hand signs.

"Uzumaki Forbidden Secret Technique: Dimensional Travel!"called out the blond as a bright white flash pierced the air and blinded all watching shinobi. When they could see again, both fighters were gone. Erased.

Nagato blinked. He sat up, groaning slightly as he stretched out the kinks in his bones. He then looked around, examining his surroundings. He was in a forest of some type, that was for sure. And, he was feeling kinda thirsty, too. He trudged forward until he reached a calm lake that was about the size of the crater he made in Konoha. He cringed, still regretting his actions. As he pooled water into his hands, he washed his face while drinking heartily. Then, he peered into the non moving water and gasped. His hair was still the same dark red it was while he was attacking Konoha. The thing was, now some silver streaks ran through his straight hair. His Rinnegan eyes were different, too. They were missing a purple ring. Perhaps, as Naruto's jutsu ran its course, he had lost some of his techniques.

After testing out his jutsus, Nagato realized that he had lost the Preta Path, Deva Path, and Outer Path, leaving him now with only the Asura, Human, Animal, and Naraka Paths. He sighed in disappointment. It didn't look like he would be getting his missing Paths back, either. Maybe Naruto, with his newly-awakened Rinnegan, had them. If he did, he would find the blond and attempt to teach him how to use the Paths of Deva, Preta, and Outer. He would try to atone for his sins. Suddenly, Nagato realized something. Where was he? Where was Naruto, the one who had sent him here? He knew the jutsu would send them to the same place, but where was here? Was Naruto still alive? And why, oh why, was Nagato stuck in his nine-year old body?
