The plot could revolve around Darcy's relationship with the other Avengers. With her hair in a ponytail, she stands out as a unique presence. Maybe she has a special connection with one of the Avengers, like a budding romance with Hawkeye. They bond over their skills - his with the bow and arrow, and hers with her scientific acumen. As they face various threats together, her ponytail becomes a recognizable feature, and the story could explore how their relationship develops through different missions.
A possible plot is that Darcy discovers a hidden power within herself while her hair is in a ponytail. The Avengers are initially skeptical, but as she starts to show signs of this power, they become more interested. For instance, she might be able to communicate with a strange alien species that has invaded Earth. Her ponytail could be a factor in this new ability, perhaps it's a conduit for some kind of energy. The story could then follow her journey as she learns to control this power and helps the Avengers save the world.
One possible fanfiction could be about Darcy being in the middle of an Avengers mission. With her hair in a ponytail, she might be using her scientific knowledge to help the team. Maybe she's analyzing some strange alien technology they've come across. She could be the one who figures out how to deactivate a dangerous device, all while her ponytail swings as she moves around the battlefield or the research area.
Well, it could be about Darcy knitting scarves or sweaters for each Avenger as a way to show her friendship or as a unique form of support during their battles. Maybe she knits Captain America a red, white and blue scarf to match his suit.
One idea could be that Darcy, being an Avengers fan, always wears a hair tie on her wrist as a sort of good - luck charm. In the fanfiction, she could be an intern at Stark Industries and one day, while wearing that hair tie, she accidentally stumbles upon a secret project of the Avengers. Maybe it's a new type of weapon or a device that could potentially change the fate of the world. This discovery then thrusts her into the middle of an Avengers - related adventure where she has to use her wits and the 'lucky' hair tie (which could end up having some hidden significance) to help the Avengers save the day.
It could be a symbol of a prophecy. In the fanfiction world, there could be an ancient prophecy that mentions a 'band of power on the wrist of a true believer'. Darcy, being an Avengers fan, is the true believer. When the Avengers face a seemingly unbeatable enemy, they start to notice that Darcy's hair tie on her wrist has some strange powers. It glows when danger is near or gives off a force field. This makes the hair tie a central plot device as they figure out how to use its powers to defeat the enemy.
Well, it could be a simple fashion statement. Maybe Darcy just likes to have a hair tie handy in case she needs to quickly put her hair up, like if she's in the middle of some Avengers - related chaos and doesn't want her hair in her face. It could also be a gift from someone, perhaps a fellow Avenger or a friend, which would add a bit of sentiment to it.
It might not seem like much, but the hair tie could be a conversation starter. Maybe one of the Avengers comments on it, and it leads to a more in - depth conversation, strengthening their bond. For example, Thor could be curious about this strange 'band' on her wrist, and Darcy's explanation could make him see her in a new light.
In fanfiction, Snape's messy ponytail might signify his state of mind. If he's going through a particularly difficult time, like dealing with his feelings for Lily or the stress of being a double agent, the messy ponytail could be a visual cue of his inner chaos. It's a way for the author to give readers a quick insight into his emotional state without having to spell it out all the time. For example, in some stories, when he's feeling especially conflicted, his ponytail is messier than usual.
Well, it could be a symbol of a past encounter. Maybe the person who was kidnapped was wearing the ponytail and the kidnapper took the hair tie as a sort of trophy or reminder. It might also be used by the protagonist later on to identify the kidnapper, like if they notice the hair tie on the kidnapper's wrist during a chase or confrontation.
Perhaps Darcy is squinting in a moment of confusion or disbelief. For example, she might be in a situation where the Avengers are doing something completely unexpected, like teaming up with an old enemy. And her squinting could be a sign of her trying to understand this new and strange situation. She could be the key to resolving the conflict in the fanfiction, using her unique perspective to help the Avengers see things they've missed.
Another plot could involve Snape having his hair in a ponytail during a time - traveling adventure. He travels back to his own school days, and his ponytail becomes a sort of symbol of his future self. He has to interact with his younger self and other characters while sporting this new - look ponytail, which causes all sorts of interesting reactions.
