Well, in the fanfiction world, if Klaus turns Elena into a vampire, she would probably have a whole new set of challenges. Firstly, she'd have to deal with her new bloodlust. Elena, being a very empathetic person, might struggle a great deal with the urge to feed on humans. Also, her relationships with her friends would change drastically. Her human friends like Bonnie and Caroline might be a bit wary of her at first. And her relationship with Damon and Stefan would also be on a different level. Damon might see her as a more equal partner in the vampire world, while Stefan might worry about her losing her humanity.
The consequences could be complex. On one hand, they might grow closer as they face the challenges of Elena's new existence. But on the other hand, Elena might struggle with her new identity and blame Stefan for turning her. This could create tension and strain in their relationship.
Caroline, for example, might be more accepting as she is also a vampire. She could help Elena adjust to her new life. Damon, on the other hand, might be jealous or feel threatened that Stefan made Elena a vampire. It could change the power balance between the three of them.
In such a fanfiction, a lot could unfold. Elena might face conflicts with other supernatural beings or have internal battles with her morality as a vampire. Also, there could be romantic complications with the people in her life.
The story changes a lot. For one, Elena's place in the supernatural world shifts. She goes from being a target of vampires to being one of them. This means she's now part of the 'in - crowd' in a way. Her daily routine would be completely different. Instead of going to school during the day, she'd be prowling at night. And her relationships with the other characters would be redefined. Stefan and Damon would have to see her in a new light, and she might start to have a different understanding of Klaus too, not just as a threat but as someone who has given her a new kind of life.
Katherine turning Elena into a vampire changes her life in many ways. For one, Elena's diet changes. She has to resist the urge to feed on humans. Socially, she becomes an outcast among normal humans. Her perception of the world also changes. She starts to see the vampire society in a different light and has to find her place within it.
There's a fanfiction called 'Elena and Caroline's New Adventure'. It takes place after the events of the show. They decide to leave Mystic Falls for a while and explore the world. Along the way, they encounter other supernatural beings and have to rely on each other. It's a fun and exciting story that shows a different side of their relationship.
Elena is often portrayed as the more innocent and selfless one in fanfiction. She usually acts out of love for her friends and family. Katherine, on the other hand, is more self - serving. For example, in many stories, Elena will sacrifice herself for others, while Katherine will look for ways to save herself first.
One great fanfiction is 'The Doppelganger Dilemma'. It delves deep into the complex relationship between Elena and Katherine. It shows how their different personalities and experiences as doppelgangers create a unique dynamic. The story has some really interesting twists where Elena starts to understand Katherine's actions more, and Katherine, in a strange way, starts to protect Elena.
