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.
They are an interesting pairing because they both have complex backstories. Riku has his journey of dealing with the darkness within him, and Xion has her own identity issues being a replica. Their different experiences can create a lot of drama and tension in a fanfiction. When brought together, their stories can intersect in unique ways. For example, Riku could help Xion come to terms with her identity, using his own experiences of self - discovery.
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.
There might be some very niche fan - made works that could potentially touch on such a concept, but it's not something that is widely known or part of the general fan - made content for Kingdom Hearts. Most fan - made stories about Sora tend to focus on his relationships with other main characters in more traditional ways, like his friendship with Riku or his love for Kairi.
One good fanfiction could be 'Riku and Xion's Unlikely Bond'. It delves into how their personalities, which are quite different on the surface, start to complement each other as they face various challenges in the Kingdom Hearts world. They might initially clash due to Riku's brooding nature and Xion's more innocent yet determined self. But as the story progresses, they find common ground in their loyalty to their friends and their fight against the darkness. This fanfiction might also explore their individual growths as they grow closer to each other.
