There's no definite answer without knowing the actual fan fiction. But it could be characters who are typically talkative in the original but are silenced in this fan - made story. Or perhaps it's a group of characters who all share the experience of being in a world where silence is the norm, and they each deal with it in different ways, with those different ways being what makes them the main characters.
One interesting aspect could be the unique interpretations of the original source material. Fan fiction often takes existing characters and settings and gives them new storylines. In 'forever silent fan fiction', perhaps there are really deep, emotional story arcs that are not explored in the original work. It might also introduce new relationships between characters that make readers view them in a different light.
Often, in such books, there are characters who represent different sides of the moral spectrum. There could be a cynical and battle - hardened soldier who has seen too much, and then there might be a more idealistic one who is still trying to hold on to their values in the midst of the chaos of the forever war. There could also be characters from the support staff, like medics, who are crucial in dealing with the aftermath of the battles.
I don't know the main characters in 'the forever story' as I haven't read it.
The main character Alicia is crucial as she is the silent patient. Theo, the psychotherapist, is also very important as he tries to unlock Alicia's secrets. There are also other characters like Alicia's husband Gabriel. His relationship with Alicia and his actions play a part in Alicia's state of being. And there are other patients and staff at the clinic which add to the overall atmosphere of the story.
There are Shoya and Shoko as the central characters. Shoya is a boy who has to come to terms with his past of bullying Shoko. Shoko, on the other hand, is a deaf girl who is strong despite the difficulties she faces. Also, there are other classmates who play important roles in the story, like Naoka who has her own feelings towards Shoya and Shoko.
The main characters are Jake Peralta and Amy Santiago. Jake is a laid - back but brilliant detective, and Amy is an over - achieving, organized detective. They are the central focus in the fan fiction as their relationship and work dynamics are explored.
Often, there's a leader - type character among the reckoners. This character is strong - willed and has great leadership skills. They guide the group through difficult situations. There could also be a character who is more of a tech - expert, providing crucial support in terms of gadgets and knowledge about the enemy's technology. And then there might be a character with super - strength or some other really powerful ability that serves as the muscle of the group.
Well, in most Kiribakudenki fan fictions, it's all about Kirishima and Bakugou. Kirishima is often portrayed as the more level - headed one, while Bakugou is the hot - headed but extremely powerful character. Their dynamic is what makes them the central focus in these fan fictions.
I don't know for sure, but they could be gardeners, or perhaps fairies that live in the garden.
Since it's a spider - centered fan fiction, the spider itself is likely a main character. But there could also be other characters created by the fan author, like a sidekick for the spider, perhaps a small insect with special abilities.
