In a 'Twilight' fanfiction titled 'take that chance', it might introduce a new love interest for one of the main characters. So, aside from Bella, Edward, and Jacob, there could be a new vampire or human character who becomes a main focus as they are the one taking the chance. For example, a new vampire arriving in Forks and taking a chance on fitting into the Cullen - human - werewolf dynamic.
I'm not sure specifically as there could be many different interpretations of a 'Twilight' fanfiction with that title. It might be about a character in the 'Twilight' universe taking a risky chance, perhaps in a relationship like Bella taking a chance on Edward in a new or different way.
I'm not certain, but if it follows the general pattern of Twilight fanfics, it might introduce a new character as the main focus. This new character could be someone who never stood a chance in the complex web of relationships in Forks. It could also be that the author decided to shift the focus from the traditional main characters slightly and tell the story from the perspective of a minor character who feels they have no chance at success or love within the Twilight world.
The main characters are likely to be the ones from the original 'Twilight' like Bella, Edward, and Jacob. In fanfiction, they might be portrayed in different lights or with different personalities.
It's hard to say without actually reading the fanfiction. It could be the underdog character who is seeking a new start in life. Maybe it's a young adventurer who has been down on their luck and this chance to change fate is what sets them on a new path.
Often, it could be the underdog characters from the original work. The ones who didn't get a fair shot in the original story.
It could be Goku. Since he's the main protagonist in DBZ, often in fanfictions he's central even when the theme is about a second chance. He might be the one getting the second chance or be involved in someone else's second - chance story.
Naruto is likely to still be one of the main characters. His journey and growth are central to the Naruto universe. Sasuke would probably also be a main character as his relationship with Naruto is so important. Sakura might also be there, as she was an important part of the original team. And Kakashi could be a main character as well, being their sensei.
I don't know for sure who the main characters are in this specific fanfiction. But it's likely that it includes the well - known Twilight characters. It could also introduce new characters created specifically for this story. For instance, a young girl who discovers the power of the mirrors and her journey might be intertwined with the existing Twilight characters, making them all main characters in the overall narrative.
Typically, in a 'the walkers twilight fanfiction', we might see the protagonists from 'The Walkers' being thrust into the Twilight world. So, it could be characters like Rick or Michonne. Alongside them, the Twilight characters would also play significant roles. Bella might be involved in some sort of encounter with the Walkers, and Edward could be using his vampire abilities to deal with the new threat or situation that the Walkers bring to the Twilight universe.
Typically, the main characters would include Bella, Edward, and the other members of the Cullen family. Since it's a Twilight - related fanfiction, they are likely to be central to the story. However, new characters might also be introduced, perhaps someone who is related to the Twilight Key in a special way, like a guardian or a seeker of the key.
