Well, it depends on how you look at it. Technically, in official Kingdom Hearts content, Sora is a key character. But in the realm of fanfiction, many writers take the essence of Sora and create their own unique stories that are not part of the official canon but are still inspired by the Kingdom Hearts universe. So, in that sense, he can be considered as a major element in Kingdom Hearts fanfiction.
They are often portrayed as two souls with a deep connection. Sora is usually the more positive and heroic one, while Roxas has his own kind of edginess. Fanfictions might show them learning from each other.
Yes, in some fanfictions Sora might be depicted as afraid of X. Fanfiction writers often explore different aspects of characters' personalities, and fear can be an interesting trait to give to Sora. It could add depth to his character and create new storylines.
It's hard to say for sure. Kingdom Hearts 3 could be the end of Sora's story in this particular arc, but the series is known for its complex and evolving narrative, so there might be more to come in the future.
I'm not aware of any official gay stories about Sora in Kingdom Hearts that involve something called 'Tentacle Kingdom Hearts'. Kingdom Hearts is mainly a story about friendship, light, and dark, and while there are diverse interpretations among fans, this seems rather unorthodox and not part of the main narrative.
In these fanfictions, the author has a lot of creative freedom. They can shape the OC to be whatever they want. The OC could be from a completely different background than the characters in the original Kingdom Hearts. This can lead to interesting plotlines. For instance, if the OC is from a world based on ancient mythology, it can introduce new enemies and challenges for Sora and the OC to face together.
Yes, there are likely many Kingdom Hearts Sora and Kairi kiss fanfictions out there. Fanfiction platforms are full of various interpretations of the relationship between Sora and Kairi. You can start by checking popular fanfiction websites like Archive of Our Own or FanFiction.net.
In this type of fanfiction, the dynamic between Sora and the Heartless can be really interesting. Some fanfics might focus on the power struggle. Sora has his own set of powers, and the Heartless are known for their menacing nature. Their interaction could lead to some intense battles or unexpected alliances. It all depends on how the author wants to portray this relationship within the Kingdom Hearts universe.
Sora's story in the end of Kingdom Hearts 3 is quite complex. He goes through a series of final battles and sacrifices. He has to face powerful enemies to save his friends and the different worlds. In the end, he makes a great sacrifice which shows his selfless nature.
Often, it's through his actions. He might hesitate before facing X or show signs of nervousness like trembling or sweating. His internal monologue in the fanfiction could also reveal his fear, with thoughts like 'I don't know if I can face X this time.'
