Killua is definitely one of the most intriguing. His journey of breaking away from the family's assassin ways and his complex relationship with his siblings and parents offer a lot of material for fanfiction. His growth and self - discovery make him a great character to write about.
Love in the context of the Zoldyck family is an interesting theme. It could be love between family members that defies the cold - blooded assassin image. Or perhaps a love story that involves a Zoldyck member and an outsider, which challenges the family's traditions and values.
Family drama is another big theme. The Zoldyck family has a complex family structure and a lot of internal politics. OCs in these fanfictions usually get caught up in this web of family drama, like dealing with rivalries between family members or trying to gain the approval of the family elders. A good example is a fanfiction where an OC has to navigate the feud between two Zoldyck siblings.
Another good one is 'My Life as a Zoldyck OC'. It stands out because it delves deep into the Zoldyck family secrets from the perspective of the OC. The story is full of twists and turns, like when the OC discovers a hidden part of the Zoldyck mansion that no one else knew about.
One unique feature is the blend of two very different universes. The Naruto world is full of chakra and ninja techniques, while the Zoldyck family from another series has its own set of assassin skills and a dark, brooding family dynamic. In naruto zoldyck fanfiction, these two elements combine to create new and exciting storylines.
The theme of redemption can also be found. Sometimes, the fanfic will have Chrollo showing signs of wanting to change or make amends, especially in relation to Kurapika. And vice versa, Kurapika might start to question his single - minded pursuit of revenge in the face of Chrollo's complex character. Another common theme is the power dynamic between them. Given their different abilities and standings in the world of 'Hunter x Hunter', how they assert and negotiate power in their relationship is often explored in these fanfics.
One common theme is loneliness. Chrollo often seems isolated in the original story, and fanfics tend to explore how his past experiences, like losing his family or being an outcast, led to this loneliness. Another theme is power - seeking. Fanfics show how his past traumas made him strive for power as a means of survival and control.
Another theme is the exploration of their unspoken connection. They have a unique relationship in the original work, and in fanfiction, this is often expanded upon. It could be a connection based on mutual understanding of the harsh world they live in or their shared experiences in the Phantom Troupe. Some stories also play with the idea of a possible romantic undertone, although it's not always the main focus.
One great 'Hunter x Hunter Chrollo Fanfiction' is 'Chrollo's Redemption'. It explores an alternate path for Chrollo where he tries to atone for his past sins. The story has really good character development and the author does an amazing job of getting into Chrollo's psyche.
One idea could be a crossover with the world of Harry Potter. Chrollo could be a dark wizard from a far - off land who comes to Hogwarts to steal some powerful magical artifacts. He could use his Nen abilities in unique ways within the magical world, creating a really interesting dynamic as the students and teachers try to figure out his strange powers.
