In a 'child of the emperor fanfic', the main characters might be the child, a mysterious stranger who comes to the court and seems to know a great deal about the child's past. There could be a strong - willed mother figure, who may or may not be the empress, and she tries to protect the child from the dangers of the court. And then there's the head of the imperial army, who at first is suspicious of the child but later becomes an ally.
Obviously, the child of the emperor would be one of the main characters. There could also be a loyal servant or bodyguard who has been with the child since birth and helps them through their trials. And perhaps an antagonist like a power - hungry noble who wants to get rid of the child to gain more power in the court.
One could be the Overlord himself. He might interact with the child in various ways, either as a mentor, an adversary, or an unexpected ally. His vast power and knowledge of the world would make for interesting dynamics with the child.
A wizard or sorcerer could be a main character. They might be the one who discovers the existence of the child of Jormungandr first. They could either befriend the child and help it understand its powers, or they could see it as a threat and try to eliminate it.
Obviously, Sakura herself would be a main character. Her friends like Naruto and Sasuke could also be main characters. Naruto might be the one who is overly excited and wants to play with child - Sakura all the time, while Sasuke would be more focused on finding a way to turn her back. Kakashi could also be involved as the mentor figure who guides them through the process.
Obviously Naruto would be one of the main characters as the title implies he's the emperor. Another could be Sasuke. He might be Naruto's right - hand man or sometimes a rival within the new empire. From the Avatar world, Aang could be a major character. He could either be an ally or someone who initially doubts Naruto's rule but later comes to respect him.
The main characters in 'child of grace fanfic' could be the 'child of grace' themselves, of course. There might also be friends or allies that they make along their journey. These could be other characters with their own unique abilities or personalities that complement or contrast with the 'child of grace'. For example, a street - smart character who helps the somewhat naive 'child of grace' navigate the more practical aspects of the fictional world they live in.
The main character is likely the 'child of mine'. But there could also be supporting characters such as the parents or guardians of the child. They might play important roles in the child's life within the fanfic.
Well, obviously the child of Jormungand would be one of the main characters. There might also be characters who are guardians or mentors to the child, guiding them through their journey. And perhaps there are antagonists who oppose the child because of their lineage.
I'm not sure specifically as I haven't read this particular fanfic in detail. But usually in such fanfics, there could be a central hero or heroine who has some special qualities or abilities related to the 'child of heaven' concept.

In a 'child of the phoenix fanfic', the main character would be the child of the phoenix of course. They would be the focus of the story. There could be other important characters too. For instance, the child's family members might be part of the story, even if they are not phoenixes themselves. They could provide emotional support or be a source of conflict. Another possible main character could be a love interest for the child of the phoenix. This character could add a romantic sub - plot to the story and also influence the decisions and actions of the child of the phoenix.
