In a Ben 10 and Naruto fanfic, their powers would be a great combination. Ben has the ability to transform into various alien forms, each with unique powers. Naruto has his chakra and his powerful jutsu. They could learn from each other. For example, Ben could teach Naruto about some of the alien technologies, while Naruto could teach Ben about chakra control and the ninja way.
One possible plot for a Ben 10 and Naruto fanfic could be that an evil force from Ben's world follows him to the Naruto world. This force wants to take over both worlds. Ben and Naruto must gather all their allies from both universes. They have to go on a journey to find the source of this evil and stop it. Along the way, they face many challenges and make new friends from both worlds.
A Naruto and Jessica Jones fanfiction could be really interesting. One idea could be that Naruto is somehow transported to Jessica Jones' world. He might be confused at first by the modern setting and the different types of powers he sees. Naruto could use his ninja skills, like his shadow clone jutsu, to help Jessica in her detective work or in a fight against a powerful enemy. His positive attitude could also have an impact on Jessica, who is often a bit jaded.
You can blend the two worlds by having characters from each world interact. For example, the ninjas of Naruto could meet the Berserkers. They might initially be at odds, but then find common ground in their fighting skills. The ninjas' use of chakra and jutsu could be compared and contrasted with the Berserkers' brute strength and rage - based powers.
In a Naruto - Vikings crossover fanfiction, the power systems could be really interesting to combine. The Vikings have their physical strength and combat skills, while the ninja in Naruto have chakra and jutsu. Maybe a Viking could be exposed to chakra and start to develop their own unique form of jutsu based on their Viking heritage. For instance, a Viking with a connection to Thor could use lightning - based jutsu in a way that's different from how a normal Naruto character would. This would create a whole new dynamic in the story as the Vikings and Naruto characters learn from each other's powers.
A possible fanfic could involve the Blue - Eyes White Dragon from Yu - Gi - Oh meeting Inuyasha. Maybe the Blue - Eyes gets transported to Inuyasha's world. It could be a really interesting story where the powerful dragon has to adapt to a new environment filled with demons and magic like Inuyasha's world. And Inuyasha might be both curious and cautious about this strange new creature.
In a Naruto Date A Live crossover fanfiction, the settings can be merged. Imagine the Hidden Leaf Village coexisting with the world of Date A Live. The villagers might have to deal with the appearance of Spirits. And the Spirits could be intrigued by the ninja way of life. The cultural differences between the two worlds would also add depth to the story. For instance, the Spirits might not understand the concept of chakra at first, but as the story progresses, they could start to learn and use it in their own ways.
I'm not sure specifically as there could be many different plots for such a fanfic. It might involve Naruto characters being transported to the X - Men world or vice versa, and then they have to deal with the different powers, cultures and challenges in that new world.
The plot could involve Naruto characters being transported to the X - Men world or vice versa. They might team up to face a common threat that is affecting both worlds, like a powerful villain who is stealing chakra and mutant powers. Maybe Naruto and Wolverine could bond over their shared experiences of having a power within them that they have to constantly control.
A really cool way to blend the power systems is to have a character from Fairy Tail use their magic to unlock new forms or abilities in a Naruto character. For example, if Wendy uses her healing magic on Naruto, it could unlock a new chakra mode that has healing properties as well as increased combat abilities. This would create a unique and exciting combination of the two power systems, and also open up new storylines and character developments.
In a merged world, the power structures would change. The Gems, who are used to being the protectors of Earth in their world, would now have to share that role with Ben. Ben's aliens could provide new ways to defend the planet, while the Gems' magic could offer solutions to problems that Ben's aliens couldn't handle alone. Also, the villains from both worlds might team up, forcing Ben and Steven to form a united front. They would need to combine their powers, like Ben using an alien form that could enhance Steven's powers, or Steven using his powers to boost an alien's abilities.
One way is through character interactions. For example, if a character from Naruto's world gets trapped in an illusion created by Kyouka Suigetsu. This forces them to adapt and find ways to break free, which can lead to interesting dynamics as they learn about the power of Kyouka Suigetsu.
