One possibility could be that the oc, being the son of Drogo, has a claim to the Dothraki leadership. He could strive to unite the Dothraki clans in a different way than Daenerys did. Maybe he focuses on forging alliances with the other kingdoms based on mutual trade and protection rather than conquest.
He could be a wild card. Since he's the son of Drogo, the Dothraki would respect his lineage. He could potentially side with Daenerys if he sees her as a means to achieve his own goals, like bringing glory to the Dothraki name. Or he could oppose her if he thinks she's leading the Dothraki astray from their traditional ways.
A great one often has a well - developed OC. The character should have a believable backstory that fits within the 'Game of Thrones' universe. For example, if the OC is from a certain tribe, their customs and values should be in line with what we know about the different cultures in the show.
Another place to check is FanFiction.net. There are many 'Game of Thrones' enthusiasts who post their works there. To find Khal Drogo OC fanfics, you might need to do a bit more digging. Try using different search terms like 'Khal Drogo and Original Character' to narrow down the search. However, the quality can vary, so read the reviews or summaries first.
Daenerys is an obvious choice. Their relationship in the original series was complex and passionate, and in fanfiction, there are so many ways to explore it further. Another good character could be Ser Jorah Mormont. His loyalty to Daenerys and his knowledge of Westeros could create interesting dynamics with Khal Drogo. And perhaps the witch Mirri Maz Duur could also be paired with him in a fanfiction that delves into the more magical and vengeful aspects of the story, exploring what could have happened if their interactions had taken a different turn.
Perhaps the OC son has a special ability or gift that Jon Arryn was trying to protect him from being exploited for. After Jon Arryn's death, the son has to learn to control this ability while also dealing with the power struggles in King's Landing. He could be a key figure in the fight against the White Walkers, using his unique skills to help the living, all while trying to uphold his father's legacy.
In fanfiction, Khal Drogo is often portrayed as a strong and fearless leader. His physical prowess and his loyalty to his people are emphasized. He is shown as a man who is initially skeptical of Daenerys but quickly comes to respect her. Daenerys, on the other hand, is depicted as a complex character. She is a young woman trying to assert herself in a male - dominated world. In the context of her relationship with Khal Drogo, she is sometimes shown as a vulnerable yet determined figure, using her intelligence to gain influence among the Dothraki.
One of the main themes is family dynamics. The Lannisters have a complex family structure, and the OC has to find his place within it. Also, the theme of survival is prevalent. In the cut - throat world of Game of Thrones, the OC has to fight to stay alive and relevant. And then there's the theme of reputation, as the Lannister name comes with both advantages and burdens.
He could be a new character created by the fanfiction writer. Maybe he's a strong and ambitious son of Greyjoy, with a desire to prove himself in the cut - throat world of Westeros, much like the other Greyjoy characters we know from the original series.
Well, an OC (Original Character) son of Bolton could be a really interesting addition to a fanfiction. He might be a cruel and calculating character, given the Bolton family's reputation in 'Game of Thrones'. He could be vying for power in the North, perhaps trying to outwit the Starks or other northern houses. Maybe he has some unique skills, like being an expert tracker or a master of psychological warfare.
