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.
The fanfic could be centered around a prophecy. The OC Targaryen has a prophecy that is somehow related to Arianne. They meet, and while trying to figure out the meaning of the prophecy, they fall in love. However, there are forces that don't want the prophecy to be fulfilled, and so they have to fight against these enemies while also exploring their relationship.
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.
The plot could revolve around a love story. Oc Targaryen might meet Arianne Martell during a tourney or a grand event in Westeros. Instantly attracted to each other, they would have to face many obstacles. Arianne's position in House Martell and the expectations placed on her, and Oc Targaryen's own Targaryen legacy and the eyes of the realm upon him. Their love would be a forbidden one in the eyes of some, but they would fight against all odds to be together.
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.
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.
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.
