Well, in many fanfics, Bilbo might use the ring's power of invisibility. He could simply slip the ring on his finger and blend into the shadows of Erebor's vast halls. Maybe he uses it to avoid detection by the dwarves when he wants to be alone or to secretly observe things going on in Erebor without being noticed.
In some fanfic interpretations, Bilbo uses the ring to hide in Erebor by being very strategic. He might know the best places in Erebor where the ring's invisibility would be most effective, like in the darker corners near the treasure rooms. He uses it not just to physically hide but also to keep his thoughts and intentions hidden from those who might be able to sense his presence otherwise.
The ring gives Bilbo a sort of stealth advantage. When using it to hide in Erebor, he can move around without making a sound or leaving a trace. He could be using it to spy on the dwarves' meetings or to find out secrets within the mountain. For example, he might use it to explore areas that the dwarves have not fully explored yet, all while remaining undetected thanks to the ring.
In some fanfics, using the ring in Erebor could have a negative impact on Bilbo himself. The ring has its own sort of corrupting influence. So, he might start to feel a stronger pull towards the ring, becoming more secretive and withdrawn from the dwarves. This could potentially damage his relationships with them over time.
He could use the natural environment around him. For example, hiding behind a big rock or a tree to avoid both Thorin and the monster.
Well, Thorin is a proud and strong character. When he finds out Bilbo is pregnant in the fanfiction, he probably steps up to take on the role of a protector. He would ensure Bilbo has everything he needs, from a safe place to stay to proper nourishment. He might also be a bit worried about how others in their group or society will react to this situation, but his loyalty to Bilbo would be unwavering.
The themes usually involve the reimagining of the story. A female Bilbo brings a different energy, so there's a theme of transformation in the story. Love and loyalty are also common themes. Whether it's the loyalty to the group or the love that might develop between Bilbo and Thorin. And there's the theme of identity. The female Bilbo has to figure out her place in the world of dwarves and hobbits while being in a relationship with Thorin.
Well, he might be really scared. He could try to find a way to escape the monster without being noticed by Thorin. Maybe he uses his small size and cleverness to hide in a small space the monster can't reach.
Yes, there might be. The Tolkien fandom is very creative and has all kinds of fan - made stories. Some fans like to explore unusual relationships and scenarios in their fanfics. However, it could be a bit hard to find exactly this one. You could start by looking on big fanfic platforms like Archive of Our Own. They have a large collection of Tolkien - related fanfics, and you can use their search function to look for keywords like 'Bilbo', 'Thorin' and 'pregnant' to see if there is such a story.
Frodo could be one. Since he was also closely associated with the ring in the original story, he might play a role in this fanfic, perhaps as a supporter or someone who has doubts about Bilbo's ability to destroy the ring.
One popular 'female Bilbo Thorin fanfic' is 'The Unexpected Bond'. It beautifully explores a different dynamic between the two characters with Bilbo as a female. Another one could be 'A New Adventure' which has some interesting plot twists involving their relationship. And 'Bilbo's Heart' is also quite good as it delves deep into the emotions of the characters in this alternate scenario.
Love is also a prevalent theme. Whether it's a platonic love or a romantic one, many fanfictions play with the idea of their feelings for each other. Some explore how their different backgrounds, Thorin as a dwarf king and Bilbo as a hobbit, influence the way they express their love and care for one another. It can be a very interesting exploration of their characters' emotions.
Redemption can also be a theme. Thorin's pride and how he might overcome it with Bilbo's help is something seen in some fanfictions. And loyalty, both to each other and to the company they are part of, is frequently a central theme as well. For example, in some stories, they are tested in terms of their loyalty to one another during difficult situations.
