Obviously, the main character would be the 18th Targaryen king OC himself. He would be the central figure around which the story revolves. His advisors could also be important characters. Maybe an old, wise maester who has been in the court for years and tries to guide the young king. And of course, his enemies, like a power - hungry lord who wants to usurp the throne.
In this fanfic, the 18 targaryen king OC is the main focus. However, there could be other interesting characters. There might be a mysterious assassin who is hired to kill the king but ends up having a change of heart. Or a foreign diplomat who comes to the kingdom with an ulterior motive but gets caught up in the king's story. Additionally, there could be a group of rebels led by a charismatic leader who oppose the king's rule, adding more conflict and drama to the story.
The main character is the OC king. But then there could be his family members. For instance, a sister who has her own ambitions and may or may not support him. There could also be a childhood friend who has now become a knight in his service. This knight could be a loyal companion, always by the king's side in battles and political disputes. And don't forget the love interest, whether it's a noble lady or a commoner girl that the king is attracted to.
One possible plot could be about the rise of the OC (original character) as a Targaryen king. Maybe he has to fight off rival claimants to the throne, using his unique skills and the power of his dragons. He could also be involved in political intrigue within the Seven Kingdoms, making alliances and enemies as he tries to establish his rule.
Obviously, the original character (oc) with telepathic abilities would be one of the main characters. This oc could be a human who suddenly discovers their powers and has to navigate the dangerous world of Twilight. There could also be the main characters from the original Twilight series like Edward and Bella. The oc might interact with them in various ways. For example, the oc could use their telepathy to help Bella understand Edward's vampire nature better, or they could be in conflict with Edward because their telepathy reveals things he wants to keep hidden.
Well, King Cold himself would surely be an important character. He could be portrayed as a strict and overbearing father figure, constantly pressuring the OC to be more like him. Frieza could also be a main character, perhaps as a jealous brother who sees the OC as a threat to his own position in the family hierarchy.
Another character could be a villain who is hunting down any remaining Targaryens. He sees the orphan boy as a potential threat because he might grow up to claim power. This villain adds conflict and danger to the story, forcing the orphan boy and his newfound friends to constantly be on the run and develop strategies to outwit him.
The two kings, of course, would be the main characters. They could be very different in personality. One might be a young and impulsive king, eager to prove himself in battle, while the other could be an older, more experienced king who is more cautious. There could also be their loyal generals. For example, the young king's general who is full of new and daring strategies, and the older king's general who has seen many wars and provides wise counsel.
Well, the central figure is surely the lost Targaryen. In addition to that, there could be a whole cast of characters. There might be a maester who has some knowledge about the Targaryens' past and helps the lost one. There could be a sellsword who becomes the lost Targaryen's bodyguard. And not to forget, if there is a dragon in the story, there could be dragon keepers or people who have seen the dragon and spread rumors about it, which in turn attracts both the good and the bad attention to the lost Targaryen.
Besides the OC, Baki could be a main character. He's a respected ninja in Suna and could be tasked with looking after the OC painter. He might be initially skeptical of the painter's abilities but later come to respect them. Another possible character is Yashamaru. Even though he's dead in the original story, in the fanfic, he could be a spirit that the painter somehow communicates with, and Yashamaru could give the painter insights into Suna's history and the people's feelings.
Obviously, Daenerys would be one of the main characters. She is a central figure in the 'Game of Thrones' universe and her presence would bring power and royalty to the story. The original character (oc) would also be a main character as they are unique to this fanfic. And the maid, who could be a simple yet strong - willed girl, would be another main character, perhaps acting as a link between Daenerys and the oc.
A 'daemon targaryen x oc fanfic' often explores unique relationships. It can show how an original character (oc) interacts with the complex and often tempestuous Daemon Targaryen. The fic might delve into power dynamics, as Daemon is a powerful figure in the 'Game of Thrones' universe. It could also explore themes of love, loyalty, and betrayal in the context of their relationship.
One great 'oc Aegon Targaryen fanfic' is 'The Dragon's New Path'. It presents an original character who befriends Aegon in a really interesting way, adding new dimensions to the world of Targaryens. The story has a great plot that keeps you hooked from start to finish.
