In this fanfic plot, the dual bladed lightsaber could be a key to unlocking an ancient prophecy. Naruto discovers the lightsaber in a forgotten tomb. As he wields it, he starts having visions of a future where the world is in great danger. He teams up with some unlikely allies, including some from the Star Wars universe who are also interested in the prophecy. Together, they embark on a journey to prevent the apocalypse, with Naruto's lightsaber skills playing a crucial role in the battles they face along the way.
A possible plot could be that Naruto is sent on a special mission to a far - off planet where lightsabers are common. There, he is given a dual bladed lightsaber by a wise old Jedi - like figure. He then has to learn the ways of the lightsaber while also dealing with local politics and power struggles. Back on Earth, his enemies sense his new power and start plotting against him. Naruto must return in time to save his village, using the skills and power he gained from his adventure with the lightsaber.
One idea could be that Naruto discovers the lightsaber in a hidden ancient temple during one of his adventures. He initially has trouble controlling it due to its unique dual - bladed nature, but with his determination and quick learning skills, he soon masters it and uses it to fend off powerful enemies. This new weapon gives him an edge in battles and also makes his combat style more diverse.
He could find it during one of his missions. Maybe he's exploring an ancient ruin and stumbles upon the lightsaber. It could be in a chest or just lying there, and Naruto, being curious, picks it up.
One idea could be that Naruto discovers the lightsaber in a hidden ninja temple that has some sort of inter - dimensional portal. He then has to learn how to use it without any prior knowledge of lightsabers. It could be a comical journey as he tries to figure out how to hold it and not accidentally cut himself or his friends.
In a fanfic where Naruto has a duel bladed lightsaber, he might have to learn new combat styles. The lightsaber requires a different form of handling compared to his usual ninja weapons. He could end up training with someone who has knowledge of lightsabers, perhaps a crossover character from the Star Wars universe. This would lead to some really cool training scenes where Naruto is learning to balance his ninja abilities with the new weapon. And his opponents would be in for a big surprise when they face him with this unexpected weapon.
Well, perhaps Naruto could use the lightsaber in his ninja battles. He might combine his chakra control with the unique abilities of the lightsaber. For example, he could infuse his chakra into the lightsaber to make it more powerful or use his ninja skills to perform acrobatic maneuvers while wielding the lightsaber.
It would change his story a great deal. For one, his battles would be different. Instead of relying solely on ninjutsu and taijutsu, he'd have the lightsaber as a new option. This could make him a more versatile fighter. His enemies would have to adjust their strategies too. Also, it could attract the attention of new foes or allies from different universes if it's a crossover fanfic. Maybe some Star Wars - like characters would show up, either to help him master the lightsaber or to try and take it from him.
In this fanfic, perhaps the blue lightsaber has some special connection to Naruto's chakra. It could be that the lightsaber was created by an ancient ninja who had some knowledge of a different kind of energy, similar to the Force in the Star Wars universe. Naruto then has to master both his chakra and the power of the lightsaber, and he uses it to protect his village from a new and unexpected threat that can only be defeated with the combined power of his ninja skills and the blue lightsaber.
Maybe Naruto is given the dual swords by a mysterious figure. As he starts using them, he realizes that they have a connection to an old prophecy. So he has to master the swords while also dealing with the various factions in the ninja world who either want to help him or stop him because of the prophecy.
Perhaps they are a gift from a mysterious and powerful being who sees Naruto's potential. This being could be observing the Naruto - verse from afar and decides that Naruto is the perfect candidate to wield dual zanpakuto. The being may have their own reasons, like wanting to see how Naruto will use the powers of two zanpakuto to change the balance in his world.
Maybe in the fanfic, Wendy is a new ninja in the village where Naruto lives. Since she has a crush on him, she secretly follows him around to learn his ninja techniques. Naruto eventually notices her and at first is confused by her behavior. But as time goes on, they start to train together and Wendy gets the chance to show her true self. Their relationship could develop from there as they face various challenges in the ninja world together.
