This sort of fanfic would probably explore themes of power and domination in a very unethical way. But it's important to note that such themes are not in line with the positive values of the 'Harry Potter' franchise. The original series is about love conquering evil, not about this kind of dark and inappropriate power dynamic.
I'm not sure if there is such a specific fanfic. Fanfics can cover a wide range of strange and unique concepts, but this one sounds rather unethical and against the spirit of the original story. The idea of making Lily Evans a slave to Voldemort is quite disturbing.
Typically, in a 'lily evans lemon fanfic', it might focus on the character Lily Evans in some romantic or relationship - centered scenarios. 'Lemon' often implies a more adult or sexual nature in fanfic terms, but if we're excluding that aspect, it could still be about her deep emotional relationships, her character growth, and her interactions with other characters in a more PG way.
If it exists, it might explore themes of power dynamics. Maybe it shows how a female Sasuke in this scenario has to navigate through a situation where she is in a subservient position, which could be related to themes of struggle and survival.
Yes, there are many. You can start by looking on platforms like Fanfiction.net or Archive of Our Own. Search for the tags 'Lily Evans' and 'Voldemort' and then filter out the works with inappropriate or lemon content. Some fanfictions focus on their complex relationship in a more platonic or alternate - universe - where - they - are - not - enemies kind of way.
If such a fanfic exists, it could be seen as a way to subvert the traditional enmity between Harry and Voldemort. The pregnancy could symbolize a new form of connection or a forced bond between them. It might also be a very dark and surreal exploration of the consequences of their intertwined fates, where something as abnormal as this pregnancy occurs as a result of some magical mishap or dark magic experiment.
One common theme is the growth of their relationship. Starting from dislike or indifference in the beginning, and then gradually evolving into love. Another theme is the Hogwarts backdrop. Most fanfics use the school environment to set the stage for their interactions.
Another theme is the exploration of redemption. Loki is often seen as a complex character who may need to find his way back to the right path, and Lily, with her good - natured personality, can be a catalyst for that. Their relationship can be a journey of Loki's self - discovery and growth.
It's hard to say for sure as this is not a typical or positive fanfic concept. But perhaps a plotline could be that there is a misunderstanding or a false accusation that leads to Tonks being treated as a slave in some way, and Harry is the only one who believes in her innocence and tries to clear her name and free her. Or maybe there is an ancient magic that has been misused and Tonks is caught in it, making her seem like a slave, and Harry uses his knowledge and courage to reverse the situation. However, we should note that these are all just ideas and this type of fanfic is not what the Harry Potter fandom usually encourages.
One unique aspect is the exploration of their magical connection. In some fanfics, Lily's powerful magic is shown to have an unforeseen impact on Voldemort's power or his plans. Another aspect is the moral contrast. Lily represents love and goodness, while Voldemort is the epitome of evil, and fanfics play with how these two opposing forces could interact in different ways.
One common theme is friendship. Since they are from different generations in the Harry Potter universe, it can be interesting to see how they could form a bond outside of a romantic or inappropriate context. Another theme could be mentorship, where Lily might offer some wisdom or advice to Ron based on her own experiences.
