Character development is a key element. Since Riku is now female, exploring how she develops in this new identity, like her self - discovery journey. Another key element is the relationships. Her relationships with other characters, whether it's friendship or something more complex, are different from the original male Riku's relationships.
Riku and Xion in fanfiction can be portrayed in various ways. Some fanfictions might focus on their growth as individuals within the context of the Kingdom Hearts universe. For example, Riku's struggle with the darkness could be intertwined with Xion's search for her identity. This can lead to really engaging stories that add depth to the existing lore of the game.
I've also heard of 'Female Riku's Ascent'. This fanfiction follows female Riku as she rises to overcome various obstacles. It's a story that not only shows her strength but also her growth as a character. The author has done a great job of portraying her emotions and the world around her in a vivid and engaging manner.
In fanfiction, the relationship between Riku and Xion can be a central theme. It might be used to explore themes of loyalty and sacrifice. For instance, if one of them is in danger, the other might be willing to put themselves at risk to save their friend, highlighting the depth of their bond.
Fanfiction about D.N. Angel's Riku and Dark can explore many aspects. It might focus on their complex relationship. For example, how Riku's innocence contrasts with Dark's more mysterious and sometimes mischievous nature. It could also delve into the emotional turmoil that Riku might experience when dealing with Dark, whether it's fear, fascination, or a sense of protection.
Perhaps they could be transported to a world where the rules of the Kingdom Hearts are reversed. Sora, who is usually the more positive and optimistic one, starts to doubt himself, while female Riku has to be the one to boost his morale. Their adventure in this topsy - turvy world could lead to some really interesting character development and new revelations about their relationship.
One interesting fanfiction could be 'Female Riku's Adventure in the Keyblade Wars'. It might explore how a female Riku would handle the complex politics and battles within the Kingdom Hearts universe. Another could be 'Female Riku and the Lost Hearts', where she goes on a journey to find and restore lost hearts in different worlds. There's also the possibility of a fanfiction like 'Female Riku's Bond with Sora', which delves into a unique friendship or more between them.
Another problem could be that it may not stay true to the original characters' essence. Fanfiction is supposed to be an extension of the original work, but when it goes into 'lemon' territory, it can distort the characters in an unappealing way. Also, this type of fanfiction might not be acceptable in many fan communities as it goes against their ethical and moral standards.
One common theme is adventure. Riku and the OC often go on quests or face challenges together. Another theme is friendship or a developing relationship. They start as strangers or acquaintances and gradually form a deep bond. Also, self - discovery can be a theme as the OC might be on a journey to find out more about themselves while being with Riku.
The theme of redemption can also be seen in some 'riku x kairi fanfiction'. Riku has had his share of dark moments in the original story, and in fanfictions, his relationship with Kairi can be a part of his redemption arc. Also, the theme of discovery is common. Discovering new feelings, new sides of each other, and new possibilities in their relationship are all things that are often written about. And of course, the theme of adventure, as they are often on some kind of journey together in these stories.
