Killua is likely to be completely devastated. He might go into a state of shock at first, not believing that Gon is really gone. Then he could become very angry, either at himself for not being able to protect Gon or at the situation that led to Gon's death.
In the Hunter x Hunter manga, the focus isn't on whether Gon smells or not. The story is more about the adventures and character development. So, the answer is no, there's no such aspect depicted.
In some fanfictions, Gon might initially be shocked. He has seen Hisoka as a somewhat eccentric but strong ally. When he discovers Hisoka's more sinister side, like his love for fighting to the death and his disregard for normal moral boundaries in battle, Gon could be conflicted. He might feel a sense of betrayal because he thought Hisoka was more on the side of 'good' in their adventures. However, Gon's own sense of justice and his unwavering belief in his friends could lead him to confront Hisoka about his true nature.
One great fanfic is 'The Unlikely Bond'. It delves into the complex relationship between Hisoka and Gon. The author beautifully captures Hisoka's twisted fascination with Gon and Gon's naivete in dealing with it. It has some really interesting plot twists that keep you hooked.
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.
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.
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.
A key characteristic is the development of their characters in a romantic light. In the original series, they have a strong friendship, but in yaoi fanfictions, it's taken further. They might have more vulnerable moments, like Gon sharing his insecurities with Killua in a more intimate way than in the original show, which adds depth to their relationship.
