Depending on the story, other dwarves like Balin or Dwalin could also be considered important characters. They are part of Thorin's group and their reactions to the OC being adopted can add more depth to the story. For example, they might be initially skeptical or they might be very welcoming, and these different attitudes can drive the plot forward.
The OC (Original Character) is the other main character. This is a character created by the fanfiction writer. Their personality, backstory, and how they interact with Thorin and the other dwarves form the core of the story.
Well, the cultural clashes and integrations can be really interesting in this type of fanfiction. The OC, coming from an unknown background, has to adapt to the dwarven culture which is rich in traditions, from their feasts to their religious beliefs. And Thorin, on the other hand, has to deal with this new individual in his clan. This interaction between different cultures and personalities can create a lot of engaging storylines.
I'm not entirely sure as it depends on the specific fanfiction. But usually, Zerrie would likely be important characters, perhaps as the adopters or some sort of central figures in the story.
A common theme is adventure. Since Thorin is often on a quest in Middle - earth, the oc gets swept up in these adventures. For example, they might be traveling with him to reclaim Erebor. Another theme is love against the odds. Thorin is a dwarf king with many responsibilities, and the oc is an outsider, so their relationship faces many challenges.
The obvious main character could be the person who is adopted. This character could be a young adult who has lost their family in a disaster and finds a new family at Station 19. They could be a bit of an outsider at first, but gradually become an integral part of the team.
Well, of course, the Avengers are the main characters in a sense. You'll have Iron Man, Captain America, Thor, Hulk etc. Then there's the adopted character. This character could be an original creation, like a young girl with psychic powers. They often become a central part of the story, interacting with each Avenger in different ways.
Obviously, Ash and Cynthia are the main characters. Ash is the well - known Pokémon trainer, and Cynthia is a very powerful trainer in the Pokémon world. In this fanfiction, their relationship changes as Cynthia adopts Ash.
Well, obviously the main character is the one who is adopted by the Malfoys. They are often an original character created by the fanfic writer. Then there are the Malfoy family members like Lucius, Narcissa, and Draco. Lucius is usually portrayed as the strict, traditional pure - blood father figure. Narcissa is the more complex mother, who may have a softer side towards the adopted child. And Draco, who can be a rival or a friend to the adopted character depending on the story.
Obviously, Harry Potter is one of the main characters as the story is about him being adopted. Sirius Black could also be a main character, as he is part of the Black family and might play a big role in Harry's new life.
The main character could be an orphan with no knowledge of magic at first. They are just a normal kid until they are adopted by the witch. The witch herself would be another main character. She could be an old, wise woman with a kind heart but also strict when it comes to teaching magic. There could also be a magical pet, like a talking cat, that serves as a sidekick to both the main character and the witch.
Harry is the central character as the one being adopted. The Castle family members, such as the parents in the family, are main characters too. There could also be other family members like siblings or grandparents who interact a lot with Harry and shape his new life in this fanfiction world.
