The plot of 'naruto and the 100 crossover fanfic' might center around a strange anomaly that transports Naruto to the universe of 'The 100'. Once there, he meets Clarke and the others. He starts to teach them some of his ninja techniques, like how to move stealthily or use chakra to enhance their physical abilities. In return, they teach him about their world's technology and survival skills. This exchange of skills could be crucial in their fight against the various factions vying for power in 'The 100' world.
In this crossover fanfic plot, the Incredibles find a strange portal and accidentally step through it, ending up in the Naruto world. They are mistaken for new ninja recruits at first. As they try to find their way back home, they team up with Naruto to complete a dangerous mission. The mission could be to retrieve a powerful artifact that has the ability to send them back to their world. Along the way, they learn about each other's cultures and powers. For example, Frozone could learn how to use ice - based jutsu from Naruto, and Naruto could learn how to better control his chakra from Mr. Incredible's discipline.
A really interesting plot could be that Naruto is mistaken for a powerful wizard. He gets involved in the battle against Sauron. His Rasengan could be a powerful weapon against the orcs and other dark creatures. Also, his friendship with the characters in Middle - earth would grow as they see his loyalty and determination, much like how his friends in the Naruto world value him.
Well, it could be about Naruto characters being thrown into the Mortal Kombat tournament. Maybe Naruto has to fight against Scorpion using his shadow clones and Rasengan. Sasuke could use his Sharingan to counter the special moves of Sub - Zero.
One possible plot could be that the Juubi somehow gets transported to the Naruto world during a strange rift in space - time. Naruto and his friends have to figure out how to deal with this powerful and chaotic entity. They might initially try to fight it, but then realize they need to find a way to seal it again, like they did with the other tailed beasts. This could lead to new alliances and power - ups for the characters as they struggle to protect their world.
Well, it could be about Naruto getting lost in space and meeting Space Dandy. Maybe they team up to fight some intergalactic villains who are after the Nine - Tails' chakra. They could use Dandy's cool gadgets and Naruto's ninja skills together.
A cool plot could be that the Sage of Six Paths in Naruto's world had a connection to Skyrim long ago. When Naruto unlocks some hidden power within himself, it accidentally triggers a link to Skyrim. Once in Skyrim, he discovers that his chakra is linked to the dragon shouts. He has to go on a quest to learn more about this connection. He meets the mages in the College of Winterhold, who are fascinated by his chakra abilities. Together, they try to figure out a way to use Naruto's power to stop a great evil that is threatening both Skyrim and, through the link, Naruto's own world.
One possible plot could be that there is a rift in the multiverse that pulls Gwen from her world, Ruby, Weiss, Blake, and Yang from RWBY, and Naruto from his ninja world into a single new realm. They must then figure out how to get back to their own worlds while also dealing with threats specific to this new realm. Maybe there are powerful entities that want to use their unique abilities for their own evil purposes.
The plot could involve a villain from Naruto's world following him to Austin and Ally's world. This villain could be trying to steal the unique musical energy (just a made - up concept for the fanfic) that Austin and Ally create. Naruto, along with Austin and Ally, would then have to team up to stop the villain. Austin and Ally could use their music as a weapon, like creating sonic waves that disrupt the villain's attacks, while Naruto uses his jutsus. It would be a fun combination of the two universes' elements.
One possible plot could be that Naruto somehow ends up in the world of 'King of the Hill'. He might use his ninja skills to help out the Hill family. For example, he could use his shadow clone jutsu to get all of Hank's lawn mowing jobs done in a flash. Maybe he'd also get into some comical misunderstandings with the local characters because of his strange appearance and abilities.
Well, it could be about Eren Yeager somehow getting transported to the Naruto world. Maybe he teams up with Naruto to fight against a common enemy like the Akatsuki who have somehow gotten their hands on Titan powers. They would have to combine their unique skills, Eren's Titan transformation and Naruto's jutsu.
