In fanfiction, their worlds can also be blended. For example, imagine the Batcave in the Hidden Leaf Village. The advanced technology of Batman's cave combined with the ninja - like secrecy of the village would create a really interesting setting for the story. And the characters would have to interact within this new, merged environment.
One way to blend Batman and Beauty and the Beast fanfiction could be to set the story in Gotham. Batman could be the 'Beast' in a sense, isolated in his dark cave - the Batcave. A new character, like a female journalist, could be the 'Beauty' who stumbles upon his world. She might initially be afraid but then start to see the good in him, much like in the original Beauty and the Beast story.
Naruto's positive and determined personality could inspire the Saints. His never - give - up attitude could be something the Saints, who also face tough battles, could learn from. For example, Seiya, who is also very determined, could find a kindred spirit in Naruto. And in reverse, the Saints' loyalty to their cause, like Athena, could be a trait that some of the Naruto characters could adopt. For instance, Naruto's friends could show even more loyalty to their village, similar to how the Saints are loyal to Athena.
To blend them well, consider their backgrounds. Naruto grew up an outcast in his village but became a hero. Leela was an orphan in a strange future world. A fanfiction could explore how these shared experiences of loneliness and rising above it bring them together. They could bond over their struggles and then use their combined strength to face challenges like a powerful villain who wants to control both their worlds.
One way to blend the Batman and Pokemon universes in fanfiction could be by having Batman encounter Pokemon in Gotham. Maybe some villain has found a way to bring Pokemon into his world and is using them for evil deeds. Batman would then have to figure out the nature of these strange creatures while also dealing with the chaos they cause.
By mixing the unique abilities. Naruto's ability to use chakra can be related to the energy sources in Gundam. For instance, chakra could be used to power up a Gundam's special attacks.
Well, Naruto is always eager to make friends and prove himself. Natsuki could be the opposite, more cautious. In a story, Naruto could convince Natsuki to take risks with him. He might drag her into a mission or adventure, and Natsuki would slowly start to adapt Naruto's can - do attitude while still maintaining her own sense of self.
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.
Magic and chakra could be combined. In the fanfiction, it could be that the power of the Chains in Pandora Hearts can be harnessed using chakra. So a character like Kakashi could figure out a way to use his Sharingan to control a Chain, creating a unique fighting style that combines the two fictional universes.
Well, the architecture and overall feel of the 'Helter Skelter' world could be incorporated into the Hidden Villages. For instance, some parts of a village could have the dark, dilapidated look of 'Helter Skelter' areas, while still maintaining the ninja - style functionality. This would create a really unique and visually interesting setting.
The storylines can be blended by introducing the concept of chocobos in the Naruto world. Imagine Naruto riding a chocobo instead of using his normal means of transportation. Also, the idea of the Cie'th from Final Fantasy 13 could be incorporated into the Naruto world. Maybe some ninja are cursed and turn into Cie'th - like beings. As for the plot, it could start with a rift between the two worlds that causes chaos and forces the characters to work together to close it.
