Imagine Luffy dies by the hands of Law, and then from the middle of nowhere, Naruto pops out.
..*Naruto holds Luffy between his arms*...
Naruto: Luffy! Hang in there.
Luffy: Sorry, pal. I couldn't keep our promise. The final battle of a pirate and a ninja.
Naruto: Don't say that. You can't die here. You are the man who will become hokag. I mean you are the man who will become the Pirate King. You have to BELIEVE IT!
Luffy: That's right. I did. Either I become one or die for it. That's the promise between me and Shanks. Well, looks like I tried my best. Naruto, I have a last request.
Naruto: What is it, Luffy?
Luffy: Please, give this hat to Shanks, and tell him that I did my best.
Naruto: Luffy... Luffy!...... LUFFYYYYYYYYYYYYYYY~~!!!
Naruto wears the straw hat, and activate his upper hax kyuubi and sage modes and unleash powerful attack on Doflamingo and Law. Secret Ninjutsu: Summoning TOPPA TENGEN GURREN LAGANN. and then Naruto flips the whole galaxy upside down to kill everyone in the universe. Then, Goku collects the Dragon Balls and make a wish to bring everything back and tell Luffy that Law will betray him, so Luffy will be aware of Law's plans.
OK, this is stupid :eww:
