One possible fanfiction could be about Sora being psychologically abused by a powerful dark force that constantly taunts him about his failures. This would add a dark and complex layer to his character's journey.
There could be a fanfiction where Sora is socially abused. Maybe in a different version of the story, the other characters start to shun him because they believe false rumors spread by an antagonist. This would make Sora feel isolated and question his relationships, leading to a story about him trying to clear his name and regain the trust of his friends.
In some fanfictions, Sora might be physically abused in a scenario where he is captured by an enemy. For example, the Organization XIII members could subject him to harsh treatment in order to extract information from him. This would create a tense and dramatic situation as Sora has to endure the pain while trying to find a way to escape.
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.
A fanfiction about Sora getting abused could also introduce new relationships. For example, if he is being abused by a group, there could be a character who comes to his rescue and forms a strong bond with him. This new relationship could then play an important role in future events in the fanfiction, either helping Sora get revenge or helping him heal from the abuse.
Sora might be initially confused. He has always been on a journey to help different worlds, so being kicked out would be unexpected. He'd probably try to reason with the people kicking him out, asking them why and trying to clear up any misunderstandings.
I really like 'Sora's Time - Travel Mishap'. It's a fun fanfiction where Sora somehow gets sent back in time. He has to deal with the consequences of changing the past while still trying to get back to his own time. It has some really cool interactions with younger versions of the characters we know. 'Sora's Hidden Power' is also a good read. It explores a new power that Sora discovers within himself, and how he uses it to fight against a new, powerful enemy.
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.
You can find 'Kingdom Hearts Aqua x Sora Fanfiction' on fanfiction.net. There are numerous stories there that explore this pairing. Just search for the relevant tags and you'll be presented with a list of fics.
Another reason might be related to power dynamics. There could be a group or an individual in a world who sees Sora as a potential rival. They fear his growing power and influence, especially if he starts to gain the support of some of the local inhabitants. So, they engineer a situation where Sora gets kicked out to eliminate the threat he poses to their position.
Some fanfictions might have a storyline where Sora and Kairi finally get a chance to have a normal life for a while. They could be in a small, peaceful world where they go on dates, learn about each other's dreams, and just enjoy the simple things. But of course, trouble always finds a way to disrupt their peace.
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.
Many fanfictions in this category also deal with themes of self - discovery. Since Sora is a well - known character, a female version of her could have different experiences and emotions while going through the same adventures, and the fanfictions often explore that. For example, how she might deal with the power of the Keyblade as a female. Another theme could be romance. Writers might explore different romantic relationships for a female Sora that could be different from what we expect in the original story.
