One interesting fanfiction could be about Killua and Illumi's relationship evolving. Maybe Killua is trying to break free from Illumi's over - protective and controlling ways. They could end up having a heart - to - heart conversation where Killua makes Illumi understand that he needs to grow on his own terms.
A common theme is the conflict between their different paths. Killua wants freedom and to make his own choices, while Illumi is bound by the family's rules and expectations. Fanfictions often explore how they deal with this divide.
One common theme in fanfics about Killua's sister is her growth and development. Writers may show her learning more about the world, becoming more independent, and perhaps even using her powers for good. She might go on adventures, similar to the main characters in Hunter x Hunter, and meet new and exciting people along the way.
Another theme is the idea of an unorthodox relationship. They are both rather strange characters in their own ways, and fanfics usually show how their relationship is not like a normal friendship or romance. It's something much more complex and full of intrigue.
Well, 'Illumi's Bond with Killua' fanfiction is quite popular. It focuses on the complex relationship between Illumi and Killua. It shows how Illumi's actions towards Killua are not just out of cruelty but also because of his own warped sense of family loyalty. Another notable one is 'Illumi's New Purpose', where after certain events in the Hunter x Hunter world, he starts to question his role and embarks on a journey to find a new meaning in his life.
The themes usually revolve around family as well. His complex relationship with the Zoldyck family is often explored. Some fanfictions show him trying to reconcile with his family or completely break away. Adventure is another common theme. Since he's a Hunter, fanfictions often send him on exciting adventures, facing new monsters and challenges, which is in line with the spirit of the original 'Hunter x Hunter' series.
The theme of loyalty is quite prevalent too. The OC and Killua form a bond where they are loyal to each other. Also, the idea of power and how to control it or use it for good often comes up. As they face various challenges, they have to figure out how to use their powers effectively and not let it corrupt them, all while their relationship grows and changes.
One common theme is adventure. Since the Hunter x Hunter world is full of dangerous and exciting places, fanfics often have the reader and Killua going on quests or exploring new areas. Another theme is friendship. They start to build a strong bond as they face different challenges together.
One common theme is growth. The reader often starts off as a relatively inexperienced character, and through their interactions with Killua, they grow both in terms of their skills as a hunter and in their personal relationships. For example, they might learn how to better control their nen abilities with Killua's help.
Many of these fanfictions also play with the idea of their growth as individuals within the context of their relationship. As Gon and Killua grow in power and experience in the 'Hunter x Hunter' world, their relationship also evolves in these fan - created stories. This can include how they deal with their own insecurities and how they support each other during difficult times.
