In this fanfiction, Bilbo and the Goblin King are the central figures. Bilbo, with his simple yet brave nature, is the focus of the story as he faces the Goblin King. However, we might also see the goblin minions as important characters in a way. They are part of the Goblin King's domain and can either help or hinder Bilbo's encounter with their king. Their actions and reactions can add more depth to the story, for example, if some of them start to respect Bilbo for his courage, it can create an interesting dynamic within the goblin community.
In this fanfiction, Bilbo might outwit the Goblin King with his wits. He could use his cleverness to escape from the goblin's clutches, like he did in the original story with Gollum. Maybe he finds a magical item in the goblin king's lair that helps him on his journey.
The main characters can include the goblin king's chief enforcer among the goblins, who is responsible for carrying out his orders. Additionally, there could be a young adventurer who stumbles upon the goblin king's realm and becomes embroiled in the power struggles and adventures within the world of the novel.
Since I don't know the specific 'goblin king novel', it's hard to say. But most likely, the goblin king himself is a main character. There could also be his loyal minions or advisers, and perhaps characters from other races like a brave human knight or a wise elf who oppose or interact with the goblin king.
I don't know the exact main characters as I haven't read it. But surely the goblin king himself is one of the main characters. There may also be his trusted advisors or generals within the goblin tribe.
Obviously, the main characters are Yugi and King Yami. Yugi is the kind - hearted and intelligent protagonist, while King Yami is the powerful and mysterious figure from the past.
Well, in the goblin avengers fanfiction, the main characters are probably a diverse group of goblins. There might be a brave goblin warrior who is always ready for a fight. There could also be a goblin inventor or a goblin with the power of persuasion. These characters would come together to form the goblin avengers and face various challenges.
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.
In a 'lion king meets humans' fanfiction, Mufasa could still be a crucial character even though he is dead in the original story. His spirit could guide Simba in dealing with the new situation of meeting humans. As for the humans, it could be a family who got stranded in the Pride Lands. Each member of the family has different reactions to the lions, and this family dynamic along with their interactions with the lions could form the main plot of the fanfiction.
Kiara would definitely be a main character. She's curious and adventurous, so she'd be likely to interact with the humans first. Kovu would also be important as he is Kiara's mate. He might be more cautious about the humans but still be involved in the interactions. And from the human side, perhaps a young and idealistic scientist who is eager to study the lions and their world could be a main character.
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.
