Leah Clearwater is also quite popular. Being the only female wolf in the pack for a long time, her story of dealing with the male - dominated pack and her own heartbreak makes for interesting fanfiction. She has a strong will and her character development can be explored in many different ways in fanfiction.
First, you need to be really familiar with the 'Twilight' universe, including the characters, the settings, and the overall storylines. For example, know the personalities of Bella, Edward, and Jacob. Then, come up with an interesting concept that can fit into this world. It could be a new adventure for the characters or a different take on their relationships. Also, make sure to have a clear plot in mind before you start writing.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like Archive of Our Own. There, you might find stories that explore Link's relationship with wolves in the context of Twilight Princess. Some might focus on his bond with the wolf form, while others could be more about his encounters with wolves in the game world.
One idea could be a story where a new wolf joins the pack with a special power that helps the pack in a new and unexpected way, like being able to communicate with other animals and warn of impending danger. Another could be a love story between a wolf from the pack and a human who is somehow connected to the Twilight world. For example, she could be a relative of Bella's and through her, the wolf discovers new aspects of the vampire - human - wolf dynamic.
One possible reason could be that she feels overwhelmed by her responsibilities. In the world of Equestria, Twilight has a lot on her plate, like studying magic, taking care of Spike, and helping her friends. In fanfiction, the writer might explore the idea that she just needs a break from it all and runs away to find some peace.
One tip is to add unique twists to the story. For instance, instead of the usual running from vampires or werewolves, have the characters run from a new supernatural threat that no one has seen before in the 'Twilight' world. Another way is to focus on the emotions of the characters during the running. Show how they are feeling, whether it's fear, determination, or a mix of both.
You can expect a lot of creativity. Maybe Link will have special powers related to wolves, or he'll communicate with them in a unique way. It could also show how his relationship with wolves affects his journey in the Twilight Princess world.
In the original 'Twilight' story, the focus is mainly on the relationship between Bella and the vampires. But in this fanfiction, the spotlight is on the wolves imprinting on Bella, which gives a whole new perspective on her character and the werewolf lore.
Spike would be heartbroken. He's like Twilight's little brother. He depends on her for guidance and love. If she runs away, he might try to find her on his own and in the process, grow up a bit as he faces challenges alone. He could also feel abandoned and struggle with his own self - worth.
