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.
First off, think about what kind of story you want to tell in the Kingdom Hearts universe. Maybe it's a new adventure for the main characters or a side story about a minor character. Make sure your writing style matches the tone of the original series and keep the magic and fantasy alive throughout.
It might be seen as a fanfic because it combines elements from various Disney and Square Enix franchises in an unconventional way, appealing to fans' imaginations and creative reinterpretations.
One benefit is that it can satisfy your craving for more content. If you've finished the games and are hungry for more adventures in the Kingdom Hearts universe, fanfiction can provide that. Another is that it can introduce you to new interpretations of characters. You might see a side of Sora or Riku that you hadn't considered before.
One great fanfic about Roxas and Xion is 'The Bond Beyond'. It beautifully explores their relationship as they struggle with their identities within the Kingdom Hearts world. The author does an amazing job of delving into their emotions and the unique connection they share.
I really like 'Bleach - Kingdom Hearts: A New Alliance'. It has an interesting take on how the powers from both series would mesh. For example, it shows how a character from Bleach might use a Kingdom Hearts - inspired weapon in a creative way. The story also delves into the backstories of some characters more deeply, which adds a lot of depth to the fanfic.
Another area of advanced theory could be related to the connections between different worlds in the Kingdom Hearts universe. In fanfic, authors might postulate new ways that worlds interact, such as hidden portals or a shared energy source that links all the worlds together. This could lead to interesting plotlines where characters discover these new connections and use them to their advantage.
Advanced theory in Kingdom Hearts fanfic gives fans a chance to expand on the existing lore. It allows them to take the concepts from the games and build on them in creative ways. For instance, if the official story only briefly mentions a certain magic spell, fanfic writers can develop an entire theory around it, like how it could be used to traverse between different dimensions.
A Kingdom Hearts fanfic might be considered cumbersome if it has overly complex plotlines. For example, if the author tries to incorporate too many characters from different parts of the Kingdom Hearts universe all at once, it can become confusing. Also, if the writing style is overly wordy and filled with long, convoluted descriptions that don't really add to the story, it can make the fanfic cumbersome.
