I'm not sure specifically which 'man fights chimp story' you're referring to. There could be various real - life incidents or fictional tales. Maybe it's about a man in a zoo who got into a confrontation with a chimp for some reason like getting too close to its enclosure.
Hisoka fanfic often focuses on his unpredictable nature. Hisoka is a complex character, so many fanfics explore his motives and desires. For example, some fanfics might dig into why he is so obsessed with strong opponents.
Hisoka is still alive in the manga. The storylines haven't led to his death yet. Maybe there'll be developments in the future, but for now, he's kicking.
Well, it could be about Harry taking on various challenges to secure rights for Teddy within the context of fanfiction. Maybe Teddy is being discriminated against in the fictional world created in the fanfic, and Harry steps up to change that.
Hisoka's origin story involves his early days as a powerful and somewhat unhinged nen user. Key events include his discovery of his nen abilities and his growing fascination with strong opponents. He has always been on a quest to find and battle those who can give him a good fight, which led him to various parts of the world in search of worthy adversaries.
Hisoka in yandere fanfiction might also display a jealous streak. If he sees the reader interacting with someone else, he could become very agitated and might even start to plan ways to remove that person from the picture. His actions are often unpredictable and a bit on the crazy side, which is typical of a yandere character. For instance, he might give a chilling smile to the person who is talking to the reader, a warning sign of his impending wrath if they don't back off.
