HisoGon

HisoGon is the slash ship between Hisoka Morow and Gon Freecss from the Hunter x Hunter fandom.

Canon
HisoGon is a ship with quite a lot of moments. Mostly because of Hisoka's crush on Gon, but not only.

Hisoka and Gon first met during the Hunter Exam. Morow was obviously intrigued by Freecss already from that moment, but Hunter x Hunter fandom thinks that he started to have a crush on Gon, only when they met for the 2nd time.

Hisoka is completely obsessed with Gon, what is emphasized almost every time Morow appears on screen. For example, when Illumi started to have thoughts about killing Freecss, Hisoka told him "Gon is mine, do not forget that. Leave him be or suffer the consequences.". He also really cares about Gon - when Illumi told him that Gon's in a really critical state, we could see how much it worried Hisoka. All the more, he tried to do something to keep him alive.

Gon might not be in love with Hisoka, but he definitely admires him and was many times impressed by his techniques in battles. Freecss also evidently likes Hisoka, despite his quirks. Knowing Gon, it's highly possible that he consideres Hisoka a friend.

A huge part of the fandom thinks about HisoGon as pedophilia, but it's hard to tell that it really is pedophilia, when Hisoka said himself, that he'll wait until Gon will become an adult and he actually waits for that.
