Another idea is that the OC has a special ability to communicate with the infected on some level. The Hunter, being an infected, senses this and is initially hostile but then starts to be more curious. The story could explore how their relationship develops as the OC tries to understand the Hunter's nature while the Hunter is torn between its natural instincts and this newfound intrigue.
One interesting story could be about a reader who discovers a unique bond with the Hunter. Maybe the reader is initially scared but then realizes the Hunter has a certain protectiveness towards them. It could involve the two of them surviving together in the post - apocalyptic world of L4D.
Well, start with a strong hook. Maybe open with a scene where the OC is in a really dangerous situation, and the Hunter is about to pounce. Then, gradually introduce the backstories of both characters as the story progresses. You also need to establish the rules of this fanfiction world. Are there any special abilities the OC has that could change the typical dynamic between a survivor and a Hunter? Consider how the Hunter's instincts will play into the relationship with the OC. It's all about building tension and character development.
One idea could be a female OC who is a skilled Nen user with a unique ability related to illusions. She could get involved in the Hunter Exam and form an unlikely alliance with some of the main characters. For example, she might use her illusions to help Gon and Killua in a difficult part of the exam.
One interesting L4D female hunter fanfic could be one that focuses on her backstory. Maybe it delves into how she became the creature she is. For example, it could be a story where she was once a normal person before some sort of virus or experiment turned her into the hunter.
One idea could be to create a 2d oc who is a time - traveling detective in a steampunk world. They could solve mysteries that are related to the alteration of historical events.
Survival is also a big theme. In the world of Left 4 Dead, they are both in a constant fight for survival. The fanfiction may show them teaming up to survive against other infected or even human threats. It's about how they put aside their differences for the sake of living in that harsh post - apocalyptic environment.
A theme that often shows up is the exploration of their unique abilities. The smoker has its long tongue attack and the hunter has its pounce ability. Fanfictions might play with how these abilities could be used in non - combat situations, like when they are working together. There's also the theme of redemption. Maybe one of them has done something bad in the past and through their relationship with the other, they find a way to redeem themselves.
One common theme is the idea of redemption. Since Hunter is a somewhat 'evil' or at least dangerous creature in the game, many fanfictions explore his journey towards redemption through his relationship with Ellis. Another theme is friendship. They come from different 'sides' but form a bond that defies expectations.
One common theme is the idea of an unlikely partnership. Since they are both infected, but have very different abilities, fanfictions often explore how they can work together. Another theme is the discovery of new emotions or a sense of self - awareness. They are basically mindless killers in the game, but in fanfiction, they can be given more depth and start to question their existence.
One common theme is the exploration of the relationship between predator and prey. The Hunter is a menacing figure in the game, and Zoey is a survivor. Fanfictions often play with this dynamic, sometimes flipping it on its head.
