It's hard to pinpoint exactly where Gon is in the manga at any given moment. It all depends on the current events and his adventures. He could be in a forest, a town, or some other setting relevant to the story's progression.
Gon undergoes a series of intense challenges and character developments. He faces powerful enemies and has to make tough choices that shape his journey.
Gon's strength in the manga varies depending on the situation and his development. At times, he surprises with unexpected bursts of power, and as the story progresses, he becomes even stronger through training and determination.
No, it's not common. Fanfiction writers tend to focus on more positive or well - explored aspects of the source material. Kidnapping is a rather dark and often complex theme to handle. So, while there might be the occasional 'gon kidnapped' fanfiction, it's not something you'll find in large numbers compared to more common fanfiction themes like friendship or love within the fandom. Also, different fandoms have different sensitivities towards such dark themes, which can also affect the prevalence of such fanfictions.
Definitely. Gon's use of nen in the manga is a key element. It determines his strength and the outcome of many situations. His nen skills evolve as the story progresses, making it an exciting aspect to follow.
