Klaus could be involved in some fanfictions. Given his power and his past interest in Elena, he might see the baby as either an opportunity or a threat. If he believes the baby has some special power, he could try to manipulate the situation to his advantage. Tyler is also a possible character. He might be involved as a friend, or if the baby has some werewolf - related aspects, he could play a role in understanding or protecting it. Additionally, Alaric is often included. As a father figure and a protector in the Vampire Diaries world, he would be there to look after Elena and offer his wisdom during her pregnancy.
Elijah could make an appearance in certain fanfictions. His noble nature might lead him to protect Elena and her unborn child, especially if there are other vampires or forces that pose a threat. Rebekah could also be part of the story. She might be jealous of Elena's situation, or she could end up being an unlikely ally. And then there's Matt. As a human and Elena's friend from before all the vampire and werewolf chaos, he could represent a connection to Elena's normal life. He might be shocked by the pregnancy but still try to support her in any way he can.
The Originals might also play a role in 'vampire diaries elena bashing fanfiction'. Elijah, for instance, who has his own code of honor, might be written as disapproving of Elena's actions and behavior. Rebekah, with her jealousy towards Elena in the show, could be further explored in fanfictions that bash Elena. Kol could be shown as having no patience for Elena's antics. These characters from the Originals can add more complexity and different perspectives to the fanfictions that are critical of Elena.
It really depends on the perspective. Elena is often seen as the good girl, the one with a pure heart. She represents the moral compass in many fanfictions. But Katherine has this allure of mystery and a long history of survival. If you like characters with depth and a darker side, Katherine might be better in the fanfiction world. However, if you prefer the more traditional heroines, Elena would be the top choice.
Yes, there are likely many Vampire Diaries fanfics out there where Elena and Damon are pregnant. Fanfiction writers often explore different 'what - if' scenarios in the Vampire Diaries universe, and the idea of Elena and Damon having a child is an interesting concept for many fans to write about. You can find such fanfics on various fanfiction websites like Archive of Our Own or FanFiction.net.
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.
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.
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 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 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 popular storyline could be Elena dealing with the challenges of being pregnant while still being in the middle of the vampire - werewolf drama. For example, she might have to hide her pregnancy from some of the more dangerous vampires who could use it against her or her loved ones. Another could be exploring how her pregnancy affects her relationships. Maybe Damon is overly protective, which causes tension with Stefan who believes she should be able to make her own choices. There are also fanfictions that might focus on the supernatural aspects of the baby, like if it has special powers that start to show even before it's born.
One common theme could be the reaction of their friends and family. For example, Stefan might have a complex reaction to the news. Another theme could be how they protect the unborn child from the various threats in the supernatural world. Also, the exploration of their relationship growth during the pregnancy is often seen, like Damon becoming more protective or Elena relying on him more.
