One major theme is identity. The male dragon OC has to figure out who he is in the context of the Hobbit world. Is he a monster or can he be something more? Redemption is also a theme in some cases. The dragon may have done bad things in the past and is now seeking to make up for it. This can create some really interesting character arcs as the dragon grows and changes throughout the story. And of course, there's the theme of adventure. Dragons are often involved in grand adventures in these fics, whether it's searching for treasure or battling other powerful creatures.
Power is a common theme. The male dragon OC often has great power, and the story may explore how he uses or misuses it. Another theme is isolation. Dragons are usually solitary creatures in Middle - earth, so the fic might deal with the dragon's feelings of loneliness. For example, in some fics, the dragon OC tries to find a place where he belongs among the other races.
A common theme is the struggle between good and evil. The male ocs in these fanfictions are often faced with making choices that will determine which side they are on. Sometimes they have to resist the temptations of dark magic or the allure of power offered by evil characters. Another theme is the discovery of new cultures and places in Middle - earth. These male ocs get to explore different regions, meet different races, and learn about the rich history and traditions of Middle - earth, which is very much like Bilbo's journey in The Hobbit.
One common theme is self - discovery. The original characters often start off not fully knowing their place or potential, but through their adventures in Middle - earth, they learn a great deal about themselves. For example, in many stories, a hobbit oc might think they are just an ordinary hobbit until they face a great danger or task and find they have hidden strengths.
A third common theme is the struggle against evil. Just as in the original story, in the fanfictions, Kili and the OC often find themselves up against various forms of evil, like orcs or dark wizards. This adds an element of danger and excitement to the story, and also shows how they rely on each other's skills and strengths to overcome these challenges.
One common theme is the elf - oc's struggle for acceptance. Since they are original characters, they often have to prove themselves in the established world of 'The Hobbit'.
One common theme is self - discovery. The original characters often start their journey not fully knowing themselves and through their adventures in Middle - earth, they learn about their strengths, weaknesses, and true identities.
One common theme is self - discovery. The female oc often finds herself in a new and strange world of the hobbits and through her interactions, she learns more about herself. For example, she might discover her courage or her ability to adapt. Another theme is friendship. The oc forms deep bonds with the hobbits, which is really sweet as they have such different backgrounds.
It could be a villain. The male dragon OC might hoard all the gold and treasures in the Lonely Mountain, and the dwarves and Bilbo have to figure out a way to get past it. This is similar to Smaug in the original story but with your own unique take on the dragon's character.
One common theme is adventure. Since it involves the Hobbit world, there are often quests and journeys. Another theme is friendship, like the relationship between Tauriel and the OC. For example, they might team up to face challenges.
Well, start with its abilities. A male dragon OC could have the power of breathing not just fire, but also a freezing mist. In terms of how it fits into The Hobbit world, it could be a new threat that the characters have to face. You can base its behavior on real - world lizard behaviors to some extent, like being territorial. And don't forget to give it a name that reflects its fearsome nature, like 'Drakar the Terrible'.
One of the common themes is identity. A dragon oc may struggle to find its true identity in a world full of different species and expectations. Also, adventure is quite common. The dragon oc could embark on a journey to discover new lands or treasures. And don't forget about the theme of magic. Since dragons are often associated with magic, dragon oc fanfictions usually have some form of magical elements, like spells or enchanted objects.
