Well, in the fanfiction, the Pokemon hair tie on the wrist might have some special powers. For example, it could glow whenever a nearby Pokemon is in distress. The protagonist, a Pokemon trainer, discovers this power accidentally. As they journey through different regions, the hair tie helps them find and rescue many Pokemon, making it an important part of their adventures.
The fact that her hair is in a bun might also play a role. It could be a cultural or traditional style in the fictional world she belongs to. When she's kidnapped, her captors might be disrespectful of this style, which angers her and gives her the motivation to resist. The bun could also be used practically during her captivity. For example, she might hide small objects in it to help her escape, like a lock pick or a small note.
Such a description might be used to make the character stand out in a fanfiction. He could be a unique character in a fantasy - based fanfic too. For example, he could be a wizard who has adapted to some modern - day human habits like wearing a hair tie on his wrist. His bun could be a way to keep his long hair out of his face while he's performing magic.
In fanfiction, a girl with a dirty hair tie on her wrist could be a sign of her being in a hurry or perhaps she's been through some sort of adventure. Maybe she was so caught up in an event that she didn't have time to clean up or change her hair tie. It could also be a unique characteristic given to her by the author to make her stand out. For example, in a fantasy fanfiction, it might be a charm that has some special power but just looks like a dirty hair tie.
It could be used as a way to identify the protagonist. For instance, in a world full of Pokemon trainers, the unique Pokemon hair tie on the wrist makes the main character stand out. Other characters might recognize it and know that the person wearing it is someone special or has a particular connection to a certain Pokemon or event.
In fanfiction, the hair tie on the wrist could symbolize the trainer's connection to a certain Pokemon. For example, if they have a Pokemon that likes to play with the hair tie, it shows a bond between them. It could also be a sign of the trainer's preparedness. They are always ready for any situation, whether it's to keep their hair out of their face or to use the hair tie for some other creative purpose in their adventures.
One way is to have it be a key to a mystery. Maybe it has a hidden mark or inscription that leads to a secret location or treasure. Another way is to have it be a tool for a Pokemon's evolution. The trainer uses the hair tie in some special way to help their Pokemon evolve.
Perhaps the black hair tie is a reminder of a past love. Felicity is constantly haunted by the memories associated with it. She meets someone new in the fanfiction, and the presence of the hair tie creates a conflict as she tries to move on from her past while still holding onto this memento.
In hair fanfiction, a black hair tie on the wrist can symbolize a connection to a particular character. It might be something that the character left behind or a memento. For example, if it was from a love interest, it could represent an unspoken bond or a longing for that person.
It could be a symbol of a particular phase in their life. Maybe when they were younger and more carefree, and now at 40, it represents a connection to that lost youth.
