What are some interesting plot ideas for a Geru Hunter x Hunter OC fanfic?

First, think about Geru's backstory. Where did he come from? Was he born into a family of Hunters or did he discover the world of Hunters on his own? For example, if he was an orphan, it could shape his personality to be more independent and self - reliant. Then, consider his nen ability. How did he discover it? And how does it affect his daily life and interactions? If his nen ability is something like telekinesis, it might make him a bit more confident in combat situations. Also, his relationships with other characters are important. Does he have a mentor? A best friend? Or maybe an enemy? These relationships can help to develop his character further.

One idea could be a female OC who is a skilled Nen user with a unique ability related to illusions. She could get involved in the Hunter Exam and form an unlikely alliance with some of the main characters. For example, she might use her illusions to help Gon and Killua in a difficult part of the exam.

One idea could be a new student arriving at the Hunter School with a unique nen ability that no one has seen before. This student then has to prove themselves in various trials and battles against the existing students. For example, they might face off against Gon and Killua in a sparring match that tests not only their physical skills but also their strategic thinking.

The OC brother could have been separated from Pitou early on in their 'lives' as Chimera Ants. He grows up among humans, learning their ways and values. When he and Pitou finally reunite, they don't recognize each other at first. The story could then focus on how they gradually discover their relation and how their different experiences shape their relationship, with Pitou being more in tune with the Chimera Ant nature and the brother being more human - like in his thinking.

The fanfic could center around the OC being hunted by a group of powerful and menacing hunters who are after something the OC possesses. This causes the OC to be in a constant state of fear. Gon gets involved when he realizes the injustice of the situation. The story could then unfold with Gon and the OC trying to outwit their pursuers, all while the OC has to confront their fear of being caught and what might happen if they are.

Another idea is a fanfic that focuses on Menchi's past. Maybe she had a mentor who taught her everything she knows about cooking and hunting for ingredients. The story could explore her relationship with this mentor, how she overcame difficulties in her training, and how those experiences shaped her into the tough examiner we see in the series.

One idea could be a male OC who has a special ability related to ants. For example, he can communicate with them on a deeper level than the normal nen abilities in Hunter x Hunter. He could use this to his advantage in battles or to gather information. Maybe he discovers a hidden ant colony that has some unique secrets about the world of Hunter x Hunter.

One plot idea could be that the OC is a healer who stumbles upon Feitan after a battle. Feitan is initially suspicious but gradually warms up to her as she heals his wounds. Another idea is that the OC is a fellow member of the Phantom Troupe in disguise, and she and Feitan are sent on a mission together, leading to an unexpected bond. Or perhaps the OC is from a rival group, but she and Feitan find themselves attracted to each other despite their allegiances, which causes a lot of internal and external conflict.

Well, a plot might involve a devil approaching a young and inexperienced Hunter. The devil offers the Hunter a deal to become the most powerful Hunter ever in return for the Hunter's soul after a certain period. As the Hunter rises in power, they attract the attention of other Hunters, some who suspect something is wrong. This could lead to a conflict between those who want to help the Hunter break the deal and those who see the Hunter as a threat due to their newfound and possibly dangerous power. Also, the devil could be using the Hunter to start chaos in the Hunter x Hunter world for its own mysterious reasons.

One way to incorporate an OC into the plot of a Hunter x Hunter fanfic is to make them a part of an existing story arc. For example, if the fanfic is set during the Chimera Ant arc, the OC could be a new Hunter sent to help fight the Chimera Ants. They could have a special skill or knowledge that is crucial in the battle. Another way is to create a new story arc centered around the OC. Maybe they discover a hidden danger in the Hunter x Hunter world that the other characters are unaware of, and they have to convince Gon, Killua, and the others to join them in facing this threat.
