Self - discovery is also a theme. Just as Bilbo discovers his own courage and capabilities during his adventures, the OC may also be on a journey of self - discovery. They could be learning about their own powers, their place in the world, or their true identities, all while being influenced by their interactions with Bilbo.
One common theme is the aftermath of his adventures. For example, dealing with the trauma of facing the dragon Smaug or the battles in Middle - earth.
A major theme in these fanfictions is the relationship changes. His friends, like the dwarves or Gandalf, might react differently to him as a vampire. Also, the theme of temptation is present. The urge to drink blood and how Bilbo resists or succumbs to it is often explored in detail. For example, in some stories, he has to find alternative ways to satisfy his vampiric thirst without harming the innocent. This adds a layer of complexity to his character and the story as a whole.
The theme of discovery is also prevalent. Many young Bilbo Baggins fanfictions depict his discovery of new places, cultures, and ideas. This could be his first encounters with elves or dwarves, and how these meetings broadened his horizons and made him question the small - mindedness of some in the Shire.
One common theme is the exploration of gender roles. Since Bilbo is male in the original, making her female in fanfiction allows for a new look at how she would handle situations in a world with traditional gender expectations. For example, how a female Bilbo would be treated by male dwarves during their journey.
Common themes in 'female Bilbo Baggins fanfic' include empowerment. A female Bilbo can be shown as breaking barriers in a world full of challenges. Also, there is often the theme of adaptation. How does she adapt to the quest and the company of dwarves? It's not just about being female, but also about how that changes the story's flow. There might be fics where she has to prove herself more because of her gender, which is an interesting take on the classic story.
One common trope is the 'fish out of water' scenario. The reader, coming from a different world or background, has to adjust to the Shire's ways. For example, they might be confused by the hobbit's love for simple pleasures like gardening and smoking pipe - weed. Another trope is the 'damsel/gentleman in distress' where either Bilbo or the reader gets into trouble and the other has to save them during an adventure.
A very popular one is 'Bilbo's Unforeseen Ally'. The OC in this story is an elf - maiden who has been exiled from her own realm. She teams up with Bilbo and they face many challenges together. The author does a great job of showing how Bilbo's hobbit - sensibilities and the elf - maiden's grace and skill complement each other in their adventures.
One possible theme could be a sense of betrayal. For example, if Bilbo feels betrayed by his companions during the adventure, it could lead to his anger. This could be related to issues like sharing of the treasure or decisions made during their journey.
One popular theme is changing the past. In many fanfictions, Bilbo tries to alter certain events in Middle - earth's history through time travel. Another theme is exploration. He travels to different times and discovers new places and cultures. For example, he might visit the ancient dwarven kingdoms at their peak.
One possible theme could be adventure. Just as Bilbo had grand adventures in Middle - earth, the cat familiar could accompany him, adding an interesting dynamic to the journey.
