One possible theme could be unrequited love. Given the complex relationship between Robert and Lyanna in the original lore, fanfiction might explore the idea of one loving the other more deeply than was perhaps known. For example, Lyanna may have had more complex feelings for Robert than just the arranged - marriage - based relationship that was set up.
One common theme could be the political alliance between their families being explored in a more romantic or personal way. For example, how they might work together to gain power in the fictional world.
If we exclude the adult - related themes that 'lemon' might imply, common themes in mermaid fanfiction could be the mermaid's longing for the human world. Mermaids might be curious about human culture, technology, or relationships. Another theme could be the mermaid's struggle to fit in, either in the human world or in their own mermaid society if they have some unique trait or ability that sets them apart.
One of the common themes could be Revan's redemption arc. Given Revan's past actions, fanfictions may focus on how he/she tries to make amends or find a new path. Also, the exploration of Revan's origin story, like where he/she came from and how he/she became such a powerful force - user, can be a theme. Additionally, Revan's role in different events in the Star Wars timeline might be explored in a way that doesn't involve inappropriate content.
Excluding adult content, themes in undertaker fanfiction can be his role in the overall narrative arc. How does he contribute to the story's progression? His unique appearance and how it affects his interactions with others can also be a theme. For example, his long hair and pale complexion might be a point of interest in stories, leading to themes about how others perceive him based on his looks.
The theme of competition also exists. There are different factions or groups within the school, and there can be a sense of competition among them. Additionally, the theme of love, in a non - adult and more innocent sense, is prevalent. The characters develop feelings for one another and have to deal with the joys and challenges that come with those emotions. In general, these themes work together to create a rich and engaging story.
Another theme could be loyalty and trust. Given their roles in the 'Attack on Titan' story, fanfics might focus on how they come to trust each other. They have to rely on one another in the face of the Titans, and this can be a central aspect of the story. It could be about how they overcome initial mistrust and build a strong bond.
A common theme is his leadership. Writers often explore how he led his kingdom, the challenges he faced, and the decisions he made. This could include things like dealing with rebellious lords or managing the kingdom's economy.
One common theme is friendship. The characters in Puppyshipping often have a strong bond of friendship that is explored in fanfiction. For example, they might go on adventures together and rely on each other's strengths.
The theme of transformation could be present. Not just her physical transformation into a Gorgon, but also a transformation in her personality as she is in a submissive state. She might learn new values, new ways of thinking, and new ways of interacting with others. It could also explore the theme of power dynamics, not in a sexual way, but in terms of who has the upper hand in different situations and how Medusa copes with it.
One common theme could be the exploration of their relationship in a more romantic or platonic way. Maybe they start as enemies but gradually develop an understanding of each other. Another theme could be their interaction within the Hogwarts social structure, like how they deal with the Slytherin - Gryffindor divide. And also, their personal growth in relation to each other, for example, how Pansy's view of Harry changes as she sees his heroic side.
