Edward and Bella could be important characters. As Renesmee's parents, they would likely be deeply involved in the situation. They might be worried about her well - being, try to protect her from any threats related to the pregnancy, and offer their support and advice.
I'm not sure if there is a specific 'Jacob gets Renesmee pregnant' fanfiction. Fanfiction can cover a vast range of ideas, but this is a rather controversial and unusual plot. It might exist in some corners of the fanfiction world, but it also goes against some of the original concepts in the source material. You would need to search through various fanfiction platforms like Archive of Our Own or FanFiction.net to find out for sure.
It could be another hybrid like herself. Maybe there's a new character who is also part vampire and part human, and they fall in love and conceive a child.
The fanfiction could revolve around Renesmee's discovery of her pregnancy. She might initially be in shock or disbelief. Then, as the story progresses, it could detail how she starts to make plans for the future. There could be a lot of internal monologue about her hopes and fears for the child, and how she wants to raise it differently from how she was raised, given her unique situation.
Yes, there are likely some out there. Some fanfiction writers focus on creating non - controversial and family - friendly stories. They might explore the idea of Renesmee's future in a more innocent way, perhaps her growing up, her relationships with her family in a positive light, without delving into inappropriate themes.
One common theme could be the challenges Renesmee faces during her pregnancy. Given her unique nature in the Twilight universe, her pregnancy might be different from a normal human pregnancy. Another theme could be the reactions of her family members, like how Edward and Bella would support her.
A prevalent theme is often the relationship aspect. If she's pregnant, it may explore her relationship with the father, whether it's Jacob or someone else. Also, there could be themes of acceptance. How the Twilight community, both vampires and humans, accept this new situation. And sometimes, there are themes of protection. With Renesmee being a special hybrid, her unborn child would also be special, so there could be a lot of focus on protecting the pregnancy.
One possible plot could be the challenges they face in their relationship due to the unexpected pregnancy. For example, how they deal with the reactions from their families and friends in the Twilight universe. Another plot might involve the preparations for the new life, like finding a safe place to stay.
The implications would be significant. First, it would change the entire perception of the characters. Jacob and Renesmee's relationship has certain boundaries in the original. This fanfiction concept would break those boundaries and create a whole new set of relationships and family dynamics. It might also face a lot of criticism from the fan community for straying too far from the source material. Additionally, it could raise ethical questions about the nature of the relationship depicted in the fanfiction, as Renesmee has a unique origin in the original story.
