A prevalent theme is honor. Lancelot was known for his honor, and the oc as his descendant is often faced with situations where they have to uphold or redefine what honor means in a different time or context. There may also be themes related to magic or the supernatural, especially if the fanfiction incorporates elements from the Arthurian legends that were associated with Lancelot, such as enchanted weapons or magical foes.
One good 'oc descendant of lancelot fanfiction' could be 'The Legacy of Lancelot's Heir' which delves into the adventures of an original character who is a descendant of Lancelot. It has an interesting plot that shows how the character tries to uphold the honor associated with their ancestor.
One common theme is power and its implications. Since Hashirama was extremely powerful, the descendant often has to deal with the expectations and fears that come with that power. Another theme is identity. Figuring out what it means to be related to Hashirama and how to live up to that legacy.
One common theme is the discovery of identity. The oc has to figure out who they are as a descendant of Gilgamesh.
Power and responsibility are common themes. Since the OC is a descendant of leviathan, they often have to deal with new - found powers and figure out how to use them responsibly. Another theme is identity. They may struggle with who they are in relation to this powerful and often mysterious heritage.
One common theme is loyalty. Both Lancelot and Merlin are loyal to Arthur in different ways, and fanfictions often explore how their loyalty to the king affects their relationship with each other. Another theme is magic vs. chivalry. Lancelot represents the ideals of chivalry while Merlin has powerful magic. Fanfictions may show how they balance these two elements or how they clash.
One common theme is friendship. Despite their different backgrounds - Merlin with her magic and Lancelot as a knight - they form a strong bond. Another theme is the fight against prejudice. In many fanfictions, Merlin has to deal with the discrimination against magic users, and Lancelot often stands by her side, promoting acceptance. Also, adventure is a big theme. They go on quests, battle evil sorcerers or magical beasts, which makes for exciting stories.
Another theme is the idea of heroism. Both Harry and Lancelot are heroes in their own right. Fanfictions often play with the concept of how they can learn from each other or work together to overcome greater threats. For example, Lancelot's experience in combat and Harry's knowledge of magic can be combined in unique ways to defeat powerful enemies.
A common theme is the clash of different cultures. Sonic is from a modern, fast - paced world, while Lancelot is from a medieval, chivalric world. So there's often a theme of how they adapt to each other's cultures.
One common theme is the secrecy of their relationship. Since they both exist in a world with strict social hierarchies and expectations, their relationship, if it involves kissing, would likely be a secret. Another theme could be the struggle between loyalty to Arthur and their feelings for each other. Lancelot is a loyal knight to Arthur, and Merlin is Arthur's friend and advisor, so any romantic involvement between them might create internal conflict.
