Who could be the main characters in 'bilbo is adopted by the company fanfic' besides Bilbo?

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.

Well, perhaps Bilbo could start learning the ins and outs of the company. He might make new friends among the employees, and get involved in various company projects. Maybe he'd even have some comical misunderstandings at first due to his different background.

The main characters would be Bilbo and the Dwarves. Bilbo, as the adopted one, would be at the center of the story. Among the Dwarves, Balin could be an important character. He is wise and could be the one who actually takes care of Bilbo in many ways. Dwalin, with his tough exterior but kind heart, could also be a significant character. Their different personalities would interact with Bilbo in different ways. There might also be a female Dwarf character introduced in the fanfic, who could be a mother figure or a friend to Bilbo, adding another layer of relationships and storylines to the fanfic.

A Laketown girl who is curious about the outside world could be a main character. She would be drawn to Bilbo because of his tales from far - away lands. And an old wise man in Laketown who has knowledge of ancient remedies could also be a main character. He would try to use his knowledge to help Bilbo regain his sight and health.

In this fanfic, perhaps Bilbo, who might be an orphan or in a difficult situation, is taken in by the Dwarves. The Dwarves could see his potential, like his cleverness or his ability to think on his feet. They might raise him as one of their own, teaching him Dwarvish culture, combat skills, and the value of loyalty within their community. This could lead to Bilbo growing up with a different set of values and skills compared to his original upbringing in the Shire, and it could also set him on a different kind of adventure, one more intertwined with Dwarvish affairs.

Hermione would be really interesting. Her thirst for knowledge would make her eager to learn from Bilbo's tales and experiences. She could also help Bilbo understand the complex magic of the wizarding world. Another great character would be Gandalf. If he somehow made his way into the wizarding world, he could offer his wisdom and guidance. And of course, Ron. His loyalty and sense of humor could provide some great comedic moments and also a strong friendship with Bilbo.

Obviously, the growing Orcs themselves could be the main antagonists. Their increased size and strength make them a greater threat to Bilbo and the other good - natured races in Middle - earth.

Perhaps a rival adventurer who discovers Bilbo's secret and tries to use it against her. This antagonist could be jealous of Bilbo's place in the group and sees her secret as a way to undermine her and take her position. He might spread rumors or try to create situations where Bilbo's secret is likely to be revealed.

Bilbo would likely interact with Gandalf again. Since Gandalf has a long presence in Middle - earth's history, he could be a key figure for Bilbo in the past. Also, the dwarves, especially Thorin Oakenshield. If Bilbo goes back to a time related to the Lonely Mountain, he would surely cross paths with them. And elves like Elrond. Elrond has a vast knowledge and his presence in different historical events makes him a likely character for Bilbo to meet.

It could be a powerful dragon that has claimed the treasure as its own and will stop at nothing to protect it.
