They often use the characters' backstories. In a crossover with Star Wars and Kingdom Hearts 3, knowing that Anakin Skywalker has a tragic past and a complex relationship with the Force helps the writer keep his personality intact when he meets Sora. Sora, with his own journey of self - discovery and battling the darkness, can relate to Anakin on some levels. By referring back to these fundamental aspects of the characters' identities, the writer can make sure that the interactions feel natural and the personalities don't seem out of place. This also applies to minor characters in both franchises.
Interaction with other characters is key. In a Kingdom Hearts 3 crossover with The Legend of Zelda, Link is a mostly silent protagonist. When he interacts with Sora, who is very talkative, the contrast helps define their personalities even more in the crossover. Writers use these types of interactions to show the unique traits of each character. Sora might be constantly asking Link questions about his world and his adventures, while Link might respond with simple nods or gestures, staying true to his character from The Legend of Zelda.
Writers study both sets of characters carefully. For example, if they are doing a Kingdom Hearts 3 and Harry Potter crossover, they would re - watch the Kingdom Hearts cutscenes and read the Harry Potter books. This way, they can ensure that Sora remains his optimistic, brave self, while Harry is still the determined and intelligent wizard. They also look at how the characters react to different situations in their original stories and try to replicate that in the crossover. If Sora is put in a situation like a wizard's duel in Hogwarts, he would likely approach it with his usual sense of adventure and a bit of naivete.
Writers need to study the source materials carefully. For the Rosario Vampire characters, understand their backstories, motives, and how they react to different situations. For example, Moka is both shy and strong - willed. In a crossover, she should still show these traits. If she's put in a new and strange situation from the other fandom, she might be shy at first but then use her strong - willed nature to face it. Don't change a character just for the sake of the crossover. Tsukune's kindness and determination should also remain intact.
For Flash, always remember his light - hearted and optimistic nature. He's quick - witted and often cracks jokes even in tough situations. So in a crossover, he should be the one bringing some levity. Arrow is more brooding and serious. His focus is on justice in a very methodical way. Writers should have him be the strategic planner in the group. Supergirl is strong - willed and has a big heart. She stands up for the little guy and should be portrayed as the moral compass of the team.
To keep the characters' personalities true, writers should study both My Hero Academia and Akatsuki characters thoroughly. For example, if writing about Shoto Todoroki in an Akatsuki - themed story, remember his cold and distant nature at times, but also his internal struggle for acceptance. Don't make him overly friendly or out - of - character. The same goes for Akatsuki members. If it's Deidara, keep his love for art and explosions. Don't change his brash and confident attitude.
Some Kingdom Hearts 3 crossover fanfictions cross over with the Pokémon universe. Imagine Sora traveling to the Pokémon world, where he has to catch Pokémon instead of using the Keyblade all the time. He could form a team of Pokémon and use them in battles against Heartless that have invaded the Pokémon world. The concept of friendship and growing stronger with your companions, which is central to both Kingdom Hearts and Pokémon, is emphasized in these crossovers.
The Kingdom Hearts and Harry Potter crossover is quite popular. You can have Sora and his friends exploring Hogwarts. The contrast between magic in the two universes is fascinating. For instance, Keyblade wielding in the halls of Hogwarts is an amazing concept.
One great Kingdom Hearts crossover in fanfiction is with Final Fantasy. The different worlds and characters blend really well. For example, Sora meeting Cloud in a unique setting. It adds a new layer of adventure and character development.
To keep the characters' original personalities in Digimon Xros Wars Pokemon crossovers, writers should first understand what makes each character unique. For Digimon, it could be their evolution lines or their specific Xros abilities. For Pokemon, it's their types and abilities. Then, when writing dialogues, make sure the words and tone match the character. A serious Digimon like Omegamon should not suddenly start talking like a goofy Pokemon. And when it comes to character development, it should be in line with what is possible in their original universes. So a Pokemon that is normally shy might gradually become more confident, but not in a way that completely changes its fundamental personality.
The Keyblade wielders like Sora, Riku, and Kairi would bring a sense of adventure and a different kind of magic to Equestria. The ponies, on the other hand, could teach them about the power of friendship in a more direct way. Donald and Goofy might be a bit startled by the ponies at first but would soon get used to them. Donald's magic could be compared to the magic of some of the unicorn ponies, and they could exchange magical knowledge.
Well, in the Kingdom Hearts universe, there's no official indication that the characters read fanfiction. But it's an interesting thought. If they did, Sora might be a bit confused at first, since fanfiction can have all sorts of wild interpretations. He'd probably take it in stride though, with his positive and open - minded nature.
