Another possibility is that in fanfiction, Gon's mother could be from a long - lost tribe of hunters with special abilities. Her return could bring new knowledge and powers to Gon. For example, she might teach Gon a unique nen technique that was passed down in her tribe. This could change the way Gon approaches his battles and his relationships with other hunters.
One interesting storyline could be Gon's mother being a secret hunter herself. Maybe she was on a super - important mission when Gon was young and had to leave him, but now she's back and trying to reconnect with Gon while also dealing with the dangerous hunter world she left behind.
She's often portrayed as a mysterious figure. Since we don't know much about her in the original series, fanfiction writers have a lot of freedom. Some portray her as a powerful and kind - hearted woman, like an angelic figure who left Gon for a noble reason, perhaps to protect him from a great danger that only she could face.
One interesting 'Hunter x Hunter Gon Killua fanfiction' could be about their adventures in a new, uncharted part of the Hunter world. They might discover a rare type of nen ability that only exists there and have to figure out how to deal with it.
A really interesting plot could be set in an alternate universe where Gon and Kurapika have different roles. For example, Kurapika could be a carefree adventurer like Gon usually is, and Gon could be more focused on revenge like Kurapika. This role - reversal would create a whole new dynamic between them and could lead to some really unique storylines.
One interesting storyline could be about a new character joining the Hunter Exam with a unique nen ability. They face all the challenges and make unexpected alliances, like teaming up with Killua and Gon to defeat some of the more difficult opponents. This new character might have a backstory that ties into the dark secrets of the Hunter world.
One common theme is growth. Fans often write about Gon growing in power and wisdom. For example, in many fanfictions, Gon discovers new Nen abilities and learns how to control them better.
One popular 'Hunter x Hunter Gon x Killua' fanfiction might be those that focus on their adventures beyond the main storyline in the anime. For example, some fanfictions could send them on a new mission in a previously unexplored area of the Hunter world. These stories often explore their deep friendship and how they support each other in different situations.
I really like 'Hisoka's Obsession'. It shows Hisoka's fixation on Gon in a more detailed and somewhat darker way. It adds layers to Hisoka's character while also developing Gon's reactions to Hisoka's strange behavior. The writing style is engaging and it's easy to get lost in this alternative take on their relationship.
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.
Friendship is a very common theme. Gon and Killua have a strong bond, and many fanfictions explore how this friendship grows and endures different trials. For example, they might face a powerful enemy together and their friendship is what helps them get through it.
Friendship is a very common theme. Their strong bond is often explored further in fanfictions. Another common theme is growth, as they both grow in strength and character throughout the original series, and fanfictions like to expand on that. Adventure is also common as they are hunters.
