Maybe in this fanfiction, the Digimon are drawn to Naruto's world. The ninjas in Naruto's world are initially suspicious of these strange creatures. But as they learn more about the Digimon and their fight against the evil forces in the Xros Wars, they decide to help. And Naruto could teach the Digimon some of his ninja techniques, like how to use chakra.
There's also the possibility that a new character created through the Xros of a Digimon and a ninja could be the most powerful. Imagine a Digimon that has absorbed Naruto's chakra and can use it to enhance its attacks. This new hybrid character could have unique abilities that neither the Digimon nor the ninjas possess on their own, making it a very powerful entity in the fanfiction.
One popular crossover could be the concept of Digimon and Pokemon teams working together in a shared adventure. For example, a story might have a Digimon Xros Wars team joining forces with a group of Pokemon trainers to defeat a common, powerful enemy. Another could be where the unique abilities of Digimon and Pokemon are combined in creative ways, like a Digimon using a Pokemon's elemental power. There are also crossovers that explore the different cultures and worlds of Digimon and Pokemon, such as Digimon characters visiting the Pokemon regions and vice versa.
The novelty. Combining Digimon Xros Wars with other Digimon series or even non - Digimon elements in a crossover creates something new and exciting. It allows fans to see their favorite characters in different scenarios and interacting with unexpected others.
The 'power - up' trope is also common. Taiki and Akari might gain new powers or abilities that are not in the original series, which helps them in their adventures. There's also the 'alternate universe' trope. In these fanfictions, the story is set in a different world from the canon Digimon Xros Wars, where Taiki and Akari have different roles or experiences. For example, they could be in a world where Digimon and humans co - exist in a more equal and different way than in the original show.
You can start by looking on fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Digimon Xros Wars Taiki and Akari' in their search bars. There are often many stories there, with different themes and writing styles.
The characters themselves are a big draw. Nene is complex and Kiriha has his own charm. Their relationship, whether it's a friendship or something more, has a lot of potential for exploration in fanfiction.
A really interesting fanfiction might be set in an alternate universe where Nene and Kiriha are the leaders of rival Digimon groups. They are constantly at odds, but when a greater threat emerges that endangers the entire Digital World, they are forced to put aside their differences and work together. Their journey could involve a lot of strategy, self - discovery, and of course, exciting Digimon battles.
Another one to check out is 'Digimon Xros Wars x Adventure: Crossover Quest'. In this fanfiction, the Digimon from Xros Wars embark on a quest that somehow links them to the events of Digimon Adventure. It plays with the idea of different Digimon generations coming together and the challenges that arise from their different worldviews and abilities.
One idea could be Davis getting involved in the Hunters' world by accident. Maybe he's exploring a new area and stumbles upon a digital gate that leads him there. Then he has to team up with the Hunters to face a new, powerful Digimon threat that is endangering both worlds.
