The struggle between light and darkness is a big theme in 'Kingdom Hearts' fanfics. Writers might create stories that show how characters are tempted by the darkness or how they fight to preserve the light. Additionally, the relationships between the main characters and the new characters introduced in the game can be a theme. For example, how Sora befriends characters from new worlds he visits. And the concept of saving the worlds from the threat of the Heartless and other villains is also a popular theme.
One popular theme is the time - traveling aspect that some elements in 'Kingdom Hearts' hint at. Fanfics might explore what would happen if characters could travel through time to change certain events. Another theme could be the creation of new Keyblade forms or powers. And the idea of uniting all the different worlds in a more harmonious way, rather than through the chaos of the main game's plot, is also something that fanfic writers like to explore.
Well, ignoring the inappropriate 'lemon' aspect, in dragon harem fanfics, cultural clashes can be a common theme. If the dragon harem consists of characters from different races or cultures, there will be clashes and also reconciliations. Also, self - discovery is often a theme. Each member of the harem may go through a journey of self - discovery as they interact with the dragon and other harem members. For example, a human in the harem might discover new magical abilities or a new understanding of their place in the world.
It's hard to say for sure. While there may be a niche group of fans who are interested in 'Kingdom Hearts lemon fanfictions', it's not likely to be as mainstream as regular Kingdom Hearts fanfictions. These types of fanfictions often contain content that might not be suitable for all audiences, which can limit their popularity.
One popular theme is alternate universes. Fans create stories where the characters exist in a different reality. For example, a world where Sora never picked up the keyblade and how that changes the fate of the different worlds. Another theme is crossovers with other non - sexual franchises. It could be a crossover with a Studio Ghibli world, where the 'Kingdom Hearts' characters interact with the unique characters and settings from those movies.
The theme of family legacy is also quite popular. Hiccup is Stoick's son and Valka is his mother. Fanfics could explore how they carry on Stoick's values while also forging their own path for Berk and the relationship between humans and dragons.
One popular theme is the complex relationships among the characters in the harem. There's often a lot of jealousy, competition, and also deep friendships that develop. Another theme could be the unique powers or abilities of the main character that attract the harem members. And sometimes, there are themes of self - discovery for the main character as they navigate through all these relationships.
Some 'kingdom hearts fanfic' are centered around the Keyblades themselves. They might explore the origin of different Keyblades or the hidden powers within them. There could be a story where a new Keyblade is discovered, and it has a unique connection to an ancient power. This kind of fanfic often dives deep into the lore of the Kingdom Hearts universe.
Power and growth are also common themes. Naruto often brings his ninja skills and determination into the Kingdom Hearts world. He has to adapt and grow stronger to face the new threats there, all while managing his relationships in the harem. Friendship is another aspect, as he forms new bonds with characters from Kingdom Hearts, which sometimes also play into the harem dynamic.
One common theme could be the exploration of different monster species' cultures. Even within the context of a harem and with the 'lemon' elements, there might be an underlying exploration of how different monster characters interact based on their species' norms. Another could be the power dynamics, as some monsters in Monster Musume have different levels of power or abilities, and this could play into the relationships in the fanfic.
One popular trope is the power - up trope. For example, Harry might gain new and powerful magic abilities through his interactions with the members of the harem. Another is the friendship - evolution - into - more trope. His friendships with the characters in the harem gradually develop into deeper, more complex relationships. For instance, in some fanfics, Hermione might start as just a friend but then develop romantic feelings over time.
One popular theme is rivalry. They are both rather mysterious and powerful characters, so stories about their power struggles or competitions can be interesting. Another theme could be a reluctant alliance, where they have to work together to face a common enemy. Maybe some sort of ancient or otherworldly threat that requires both of their unique abilities.
