In an 'Ahsoka x Naruto' fanfiction, a plot could involve a prophecy. The prophecy states that a warrior from a different realm (either Ahsoka's or Naruto's) will come and help save the other world from a great evil. Ahsoka arrives in the Naruto world following this prophecy. Naruto, being the hero of his world, is assigned to work with her. They have a bit of a rocky start as their cultures are so different. But as they face challenges together, they grow closer and combine their skills, Naruto's Rasengan and Ahsoka's acrobatic combat skills, to face the impending doom.
Maybe Ahsoka ends up in the Naruto world somehow. She is mistaken for a powerful shinobi at first. Naruto is intrigued by her different look and the strange weapon she wields. They start training together, and Ahsoka's Jedi discipline starts to influence Naruto's more impulsive nature. They find out that there are dark forces at work in both their worlds that are related. So, they decide to travel between the two worlds to stop these forces from causing chaos everywhere.
One possible plot could be that Naruto and Ahsoka are brought together through some sort of interdimensional rift. They then have to learn about each other's worlds and powers in order to find a way to get back to their respective universes. Along the way, they might face common enemies that are drawn to the energy of the rift and team up to defeat them.
Another plot could be that Naruto, during one of his travels, somehow ends up in the Star Wars universe. He meets Ahsoka and they start an adventure together. Ahsoka is intrigued by Naruto's never - give - up attitude and Naruto is amazed by Ahsoka's connection to the Force. They go on a quest to find a way to send Naruto back home while also helping the people in the Star Wars universe.
Another plot could involve a prophecy that foretells the coming of a 'Chosen One' who has the power of both the demigods and the Jedi. Percy and Ahsoka are both thought to be possible candidates. They are brought together by the gods and the Jedi Council to figure out which one of them it is. During this time, they face challenges that test not only their physical abilities but also their moral compasses as they come from very different backgrounds but share the same overarching mission.
A plot could involve Ahsoka getting lost in Naruto's world. Naruto then takes it upon himself to help her find her way back home. Along the way, Ahsoka teaches Naruto some of her Jedi skills and Naruto shows Ahsoka the power of friendship and the Ninja way. They also encounter various threats in Naruto's world like rogue ninjas who are after Ahsoka's unique abilities.
One possible plot could be that Naruto is somehow transported to the X - Men universe. He teams up with Wolverine. Naruto's unique ninja skills, like his shadow clones, could be used in combat against the Brotherhood of Mutants. Wolverine could teach Naruto about the concept of mutants and their struggles, and Naruto could in turn show Wolverine some of his ninja wisdom.
One interesting plot could be that Naruto is somehow transported to the X - Men universe. He teams up with Wolverine. Naruto's ability to create shadow clones could be used in interesting ways during battles, like confusing the enemies. Wolverine could teach Naruto some combat skills from the X - Men's fighting style. They could go on a mission to stop a powerful mutant villain who has plans to take over the world, using Naruto's chakra powers and Wolverine's adamantium claws.
Well, a plot could involve a villain in the Naruto world who is creating some sort of dark energy that is affecting both dimensions. Kirby, being a hero in his own world, senses this and travels to the Naruto universe to stop it. Along the way, he teams up with Naruto. Naruto is amazed at Kirby's power to transform by swallowing enemies. Together, they face off against the villain and his minions, with Kirby using his copied ninja skills and Naruto using his jutsu.
One possible plot could be that Robocop is somehow transported to the Naruto universe. He teams up with Naruto to fight against a new threat that is using advanced technology similar to what created Robocop, but in a more malicious way. Naruto's ninja skills combined with Robocop's firepower would make for some epic battles.
One possible plot could be that Naruto is on a mission in a desert area and accidentally stumbles upon the tomb of the mummy. When the mummy awakens, Naruto initially tries to fight it, but then realizes that the mummy has some sort of connection to an ancient chakra source. They then form an uneasy alliance to explore and protect this power from falling into the wrong hands.
One possible plot could be that Naruto somehow gets transported to the Titanfall universe. He might use his ninja skills to outmaneuver the Titans at first, but then he starts to learn about the technology there and teams up with some of the Pilots. Maybe he teaches them some of his chakra - based techniques in exchange for learning how to pilot a Titan.
