But that would be a GOOD ending. A sucky ending (involving the Pulp Fiction sequence) would go thus:
After arriving at Raftel, they go through a number of traps, barely escaping alive. They also have to solve a series of riddles, all written in Poneglyphic. Robin is able to translate all of them, and even guess a few, but most are answered individually by different crewmembers. The last riddle is solved by Luffy himself (he just punches down the wall the Riddle was on.) and they all enter the final chamber. There, they see a single, shoddy steamer trunk (stereotypical treasure chest). Nami is not pleased by the lack of immense wealth. Everyone is nonplussed except Robin and Luffy. Gulping audibly, Luffy opens the chest just a crack. A golden-orange light pours out. Throwing back the lid completely, Luffy stands dazzled by the light.
Nami: Is that!–
Sanji: It can't be...
Robin is in shock. Tears are streaming down her face as she stands stock-still. Luffy reaches into his pocket, and pulls out the blank sheet of Paper Ace gave him. Looking at the paper he stares awestruck at the chest. Suddenly, he slams the chest close. A look of grim determination settles over his features.
The story timeskips to Fuschia Village, where the Pirate King Luffy D. Monkey is about to be executed.
Luffy: My treasure? No way, I'm not givin' you that! But if you want One Piece, it's still there. Go ahead, take it. I never want to see that Thing again.
The halberds descend, and Luffy carries the secret horror of One Piece to his grave.
Dude, that is SERIOUSLY disturbing. I pray that doesn't happen.
I want something involving Usopp for some reason. Like a spin-off, mainly comedy. NOSE PIECE!
Chopper- The Blue
Robin- The Flat
Franky- The Metal
and their quest to stop Arlong the Saw from getting the coveted "Perfume of the gods". Foxy is an ally after a defeat and gives help whenever he can. Jango and some marine subordinates are also in it with Arlong.
Mozu and Kiwi help with treasure related issues.
Buggy will be involved.
That's all I can think of. I'm going to try to write one or get someone else to write it for me because I'm lazy.
