Another theme is redemption. Matt often feels overshadowed by the vampires in Elena's life in the show. In fanfiction, it's a common theme to see Matt being redeemed in Elena's eyes, showing that he is just as important and worthy of her love.
One common theme is friendship. Since they were friends before any romantic feelings came into play, many fanfictions explore how that strong friendship foundation can either support or complicate a romantic relationship between them.
One common theme is love. Since the Vampire Diaries is full of complex relationships, fanfictions often explore different love interests for Matt Davis's character. Another theme is power. How his character might gain or struggle with power in different situations.
One common theme is the power dynamic. Kol is an ancient and powerful vampire, while Elena is a human - turned - vampire with her own strength. Another theme is the exploration of the unknown. Since Kol has a different personality compared to the other vampires Elena has interacted with, it's like she's stepping into uncharted territory with him. Also, redemption can be a theme, as Kol might seek redemption through his relationship with Elena, or Elena might see the potential for good in Kol.
One common theme could be her struggle with PTSD. After the abuse, Elena might constantly relive the trauma, which could be shown through nightmares or flashbacks. Another theme could be her isolation. She may push away her friends, like Stefan and Damon, because she doesn't want them to see her as weak or damaged. Also, there could be a theme of revenge. Elena might seek to get back at her abuser in some way, either through direct confrontation or more devious means.
One common theme is protection. Alaric often acts as a protector figure for Elena in fanfiction, much like he did in the show. Another theme is mentorship, as Alaric can be seen guiding Elena through the complex world of the supernatural.
Well, a prevalent theme is the idea of fate and how they are drawn to each other despite all the odds. Also, the theme of secrecy and the forbidden love aspect is quite common. Since Elena is part of the Mystic Falls gang and Klaus is an enemy in many ways, hiding their relationship from others is often explored in these fanfictions. And of course, there's the theme of sacrifice, where either Elena or Klaus has to sacrifice something for their love.
One common theme is the reaction of her love interests. For example, Damon might become extremely protective and vengeful when Elena is hurt. Another theme is her own strength in the face of pain. She often has to dig deep within herself to survive the injury.
One common theme could be criticizing Elena's actions regarding her relationships. For example, some fanfictions might bash her for being indecisive between Stefan and Damon. Another theme could be her role in the supernatural events in Mystic Falls. Maybe she's seen as too self - centered in some stories, always putting her own needs and desires above others when it comes to dealing with vampires, werewolves and witches. Also, her character development might be a target, with fanfictions suggesting she didn't grow or change in a positive way as the series progressed.
One great fanfiction is 'Elena and Matt: The Road Not Taken'. It explores an alternate universe where Elena realizes her feelings for Matt earlier. It has a lot of sweet moments between them and shows a different side of their relationship compared to the show.
There are also fanfictions that focus on the power dynamics between them. As a vampire, Stefan has certain powers, and how that affects their relationship, whether it creates a sense of imbalance or a unique bond, is explored. For instance, Stefan's ability to protect Elena with his vampire strength can be a central plot point in some fanfictions.
One common type is making her out to be a damsel in distress in a negative way. Instead of seeing her as a character who needs help sometimes, it's exaggerated so she seems overly helpless and annoying. For instance, she's constantly getting into trouble and relying on others in a very unappealing way.
