The characters in 'Modao Zushi' light novels are very special. They have diverse personalities and backstories. For example, the main character has his own struggles and growth journey, which is full of twists and turns. Also, the relationships between the characters, be it friendship or rivalry, are well - crafted.
Gon in fanfiction can be very single - minded in his pursuit of goals, just like in the original. He might be a bit more naive at times, which can lead to interesting plot twists. Killua is often portrayed as having a complex emotional side. He struggles with his past as an assassin and his loyalty to Gon. His cool exterior may crack in some fanfictions, showing his true feelings.
I don't think so. There haven't been any official announcements or indications that the HxH manga will continue. But you never know, maybe there'll be a surprise in the future.
