There could be a fanfiction where Nessie and Jacob have to face a new threat together. In this story, they might have to combine their powers and knowledge to protect their family and the Quileute tribe. It could show their relationship growing stronger as they rely on each other. For example, Nessie might use her special senses to detect the approaching danger, while Jacob uses his speed and strength as a werewolf to fend it off. And throughout this, their friendship could turn into something more romantic.
One popular fanfiction might be about their adventures together in the forest. It could explore how Nessie's unique abilities and Jacob's werewolf nature interact in different situations.
One popular theme is the complex relationship between Jacob and Nessie. Since their relationship is somewhat unconventional given their different natures, exploring the challenges they face in being together is a common theme. Another theme could be Nessie's growth and how Jacob influences it. Also, themes related to the supernatural world they inhabit, like how they deal with other supernatural beings in relation to their relationship.
One popular Jacob and Renesmee fanfiction could be 'Jacob's New Role'. In this story, Jacob has to deal with his complex feelings for Renesmee as she grows up. Another might be 'Renesmee's Choice' which focuses on Renesmee's struggle between different paths in life and how Jacob factors into it. There are also ones that explore their relationship in a more magical and adventure - filled setting, like 'The Adventures of Jacob and Renesmee' where they go on a journey to discover a hidden part of the Twilight world.
One popular Bella and Jacob Twilight fanfiction might be those that explore an alternate ending where Bella chooses Jacob instead of Edward. In these stories, the author delves into how their relationship would develop, how the werewolf pack would react, and how the Cullens would handle the situation.
One common theme is the struggle between different species. Since Jacob is a werewolf and Nessie is half - vampire, their relationship often has to deal with the prejudices and hostilities between their two groups. Another theme is love conquering all. Despite the odds, their love is usually depicted as strong enough to overcome any difficulties.
In the fanfiction, it can expand on the powers that Nessie has and how Jacob interacts with those powers. It might also add new characters that are related to their relationship, like friends or foes that are specifically interested in their union. This adds more layers to the story compared to the original where the focus was more spread out among different characters. Also, it can show more of the cultural aspects of the werewolves and vampires in relation to their relationship, which wasn't fully explored in the original Twilight story.
