Challenge
I issue the challenge to any writer, because I'm surprised by the lack of Naruto/One Piece Crossover's of this nature.
The One Piece world and Elmental Nations must be the same(NO CROSS DIMENSION OF ANY KIND)
Naruto must join the Strawhats(The Strawhats come to his village, he can't just up and leave because it wouldn't Naruto)
Story must start before Sabody arc and at the beginning of the Pain arc.
Have Naruto keep all his abilities, no devil fruit, but give him anything else in the One Piece world
Finally, when Naruto decides to join the Strawhats, don't do it because Luffy forces him, do it because Sasuke decides to head for the grand line(Sasuke's Story must play out the same up to the Pain Arc)
I write this story myself but I can't write worth shit, but the Idea been spinning in my head for a while so if anyone can do this that'll be great.
