Dimitri is an obvious choice. Their relationship in the original series is so complex and full of passion. In fanfiction, it can be explored even further, like what would happen if they had to face an even greater threat together. Adrian also makes for an interesting pairing. His charm and different approach to life compared to Rose can create a lot of interesting storylines.
A great fanfiction idea could be Rose getting transported to a different time or dimension. In this new place, she has to adapt quickly and find a way back home. Along the way, she meets different versions of the characters she knows and forms new alliances. This type of story could really test her character and show how resourceful she is.
In the Vampire Academy setting, Rose's pregnancy could be a huge shock to the system. The strict rules and hierarchies of the academy might not be prepared for such a situation. Her pregnancy could lead to new alliances being formed, like other dhampirs or vampires coming to her aid. Also, the medical facilities at the academy could play a role in her prenatal care, and there could be a whole sub - plot about the secrecy or lack thereof regarding her pregnancy within the academy walls.
A fanfiction could involve Rose being captured by Strigoi. She then has to use her wits and combat skills to escape. Along the way, she discovers some secrets about the Strigoi that could change the way the dhampirs and Moroi view them. For example, she might find out that some Strigoi were forced into their state against their will in some strange, dark ritual.
One common character paired with Rose could be Dimitri. Even in the human world fanfictions, their relationship is often explored. He might follow her to the human world to protect her or they could be reunited there after being separated in the vampire world. Their dynamic of mentor - protege and their underlying romantic tension would still be a major part of the story.
I really liked 'Lissa and Rose: The Unseen Adventures'. This fanfic takes the two on a journey outside of the normal Vampire Academy setting. They face new challenges together, which makes their friendship even stronger. The writing is quite engaging and it's easy to get lost in the story.
Love is a very common theme. Many fanfictions focus on the romantic relationships between the characters, like Rose and Dimitri. Their love story is often explored in different ways, sometimes with added drama or new challenges.
I really like 'A Rose and Adrian Adventure'. It takes them on a new quest outside of the typical Vampire Academy scenarios. It's full of action and also shows their romantic side. They face new enemies together and in the process, their relationship becomes even stronger.
There are many great fanfictions out there about Rose and Dimitri's kiss. One possibility is that the kiss could be a turning point in their relationship. It might be a moment of passion that has been building up over time, with all the tension between them finally exploding into that one kiss. In some fanfictions, this kiss could lead to them finally admitting their true feelings for each other and facing the challenges that come with their relationship, like the rules of the academy and the danger from the Strigoi.
There could be many fanfictions centered around Lisa Rose's haircut in Vampire Academy. Maybe in one, her new haircut is a symbol of her newfound independence. It could be that she cuts her hair short after a major event in the story, like breaking free from a controlling relationship or finding her true self.
