The first step is to find common elements. For instance, both universes have strong - willed characters. You can start by having a character from one universe admire the qualities of a character from the other. Then, introduce a common threat that requires the combined efforts of both Naruto and Sekirei characters. Also, you can blend the power systems. Maybe a Sekirei could learn to use chakra or Naruto could gain a Sekirei - like power.
The power systems can be blended. In Naruto, there are chakra and jutsu, while in Pokemon there are different types of moves and abilities. A story could have a Pokemon girl teach a Naruto character about the unique aspects of Pokemon powers, and in turn, the Naruto character could share some ninja techniques. Maybe a Pokemon could learn to use a basic ninja move like the substitution jutsu, and a Naruto character could learn to communicate with Pokemon like the Pokemon girl does. This exchange of skills can help blend the two universes.
The RWBY and Naruto universes can be blended well in fanfiction by having the characters share their skills. For instance, Yang's strength could be combined with Naruto's Rasengan for a super - powerful attack. Also, the different settings can be merged, like having the Hidden Leaf Village exist in the same world as Vale.
The two universes can be blended well by focusing on the values of the characters. Both Naruto and the characters in Case Closed have a strong sense of justice. You can build a story around this common value. Maybe there is a conspiracy that threatens the justice system in both worlds. The ninjas and the detectives would then come together to uphold justice. This could involve Naruto using his rasengan to break through physical barriers during investigations, while Conan uses his sharp mind to figure out the motives behind the conspiracy, which are often related to power struggles or revenge, just like in his own world.
In Naruto in Overwatch fanfiction, the concept of elemental jutsu can be really interesting. Naruto's fire - style jutsu could be related to some of the fire - using heroes in Overwatch like Ashe. His water - style jutsu could be used in a creative way, like for defense or to put out fires in the Overwatch maps. And the idea of chakra could be something new to the Overwatch universe. It could be a power source that some characters start to tap into, leading to new abilities and power - ups.
Character relationships are also key. You could have Naruto befriend a Sekirei who is out of place in the ninja world. Their friendship could grow as they help each other understand their respective worlds. This would allow for a lot of emotional depth and character growth in the story. You could also introduce conflicts based on the differences in their worlds' values. For instance, the ninja's code of loyalty might clash with the Sekirei's concept of their purpose. Resolving these conflicts can make the fanfic more engaging.
Well, you can start by having the settings interact. For instance, the forest in 'Into the Woods' could connect to the forested areas around Forks in 'Twilight'. The characters' traits can also be combined. The vampires' elegance and strength in 'Twilight' could be paired with the cunning of some 'Into the Woods' characters like the fox. Also, the magical elements from 'Into the Woods' like spells and wishes could influence the events in the 'Twilight' universe.
One way to blend them is through character crossovers. For example, imagine Naruto characters having the Force. Naruto could be a Jedi with his strong willpower and determination being similar to the Jedi way. His shadow clones could be used in unique combat situations against Sith Lords. Another aspect could be the settings. Konoha village could be like a planet in the Star Wars universe, with its own political intrigue and power struggles, just like the various planets in Star Wars.
One way could be through a crossover spell or a magical portal. Imagine Naruto accidentally stumbling through a portal into the world where Jessica Rabbit exists. His ninja skills would be quite out of place there, but his determination and ability to adapt could lead to some interesting adventures. He might have to use his shadow clone jutsu to deal with the various situations in this new and strange world filled with toons.
The cultures of their universes can be blended. Naruto's world has a strong sense of community and loyalty within the ninja villages. Sephiroth's world might have different values. By having the characters interact and learn from each other's cultures, like Naruto teaching Sephiroth about friendship and she teaching him about some unique aspects of her world's technology or magic, it can blend the universes well. Also, the settings can be merged. Maybe there's a place that exists in both universes but in different forms, and they have to go there together.
One way to blend them could be through a crossover of characters. For example, Dante from Devil May Cry could be transported to the Naruto universe. He might be seen as a powerful and mysterious outsider, with his unique weapons and combat skills. His devilish powers would be a novelty in the ninja - filled world of Naruto. Maybe he could team up with Naruto and his friends to fight a common enemy, like a powerful demon that has somehow infiltrated the ninja villages.
