Sometimes, new characters are created specifically for the crossover fanfiction. These characters might be hybrids of the two universes, like a half - goblin, half - wizard, who then become important main characters in the story, helping to bridge the gap between the two different fictional worlds.
There might be a lost prince or princess who is trapped in the labyrinth. And then there's a commoner who stumbles upon them. The prince/princess is used to a life of luxury but has to adapt to the harsh reality of the labyrinth, and the commoner has street - smart skills that help them both survive. As they spend time together, love blossoms between them. There could also be a powerful wizard or sorceress as one of the main characters, who uses their magic to protect their loved one within the labyrinth, creating a relationship full of power dynamics and mystery.
There's no way to know for definite without reading it. But it's common in fanfiction to keep the main characters from the original source material. So, we could expect to see Sarah, the young girl who entered the Labyrinth in the movie. And Jareth, the Goblin King, would probably also be a major character. There could also be some side characters from the original 'Labyrinth' who are given more prominent roles in this fanfiction, or there could be entirely new characters introduced by the author to drive the story forward.
Obviously Naruto and the Kyuubi are the main focuses. Since it's about their crossover, the story often revolves around their connection and how they interact with the new elements introduced in the crossover.
I don't know for sure, but there might be a brave adventurer as one of the main characters.
Without having read the 'King of Labyrinth Novel', it's difficult to say precisely. However, if there is a king, he is likely to be central. There could be advisors to the king, perhaps some magical creatures that play important roles. Maybe there are also characters from outside the labyrinth who enter and interact with the king and the world inside the labyrinth.
I don't know the specific 'labyrinth graphic novel' you're referring to, so I can't say for sure. It could have a brave hero as the main character, someone who is fearless in the face of the labyrinth's challenges.
Often, there's a brave and curious protagonist. This character is usually the one who drives the story forward, eager to explore the stars. There might also be a wise mentor figure, who has more experience and guides the protagonist. And then there's the sidekick, a loyal friend who is always there to support the main character.
Typically, Ches and Sa are the main characters. They are at the center of most of the stories.
The spider character itself is, of course, a main character. This could be a well - known spider - like superhero from mainstream media or an original creation. Often, there are also sidekick characters who help the spider in their adventures. For example, a tech - savvy friend who creates gadgets for the spider.
Well, obviously the members of the Jackson 5 themselves are the main characters. Michael Jackson, Tito, Jermaine, Marlon, and Jackie. They are often depicted in different situations, like preparing for a big concert or dealing with family matters.
