Perhaps Jaune Arc has a special power that is unknown in the Game of Thrones world. This power draws the attention of various female characters. Some may see him as a means to gain power, while others are genuinely attracted to him. He could start a journey to uncover the secrets of his power while dealing with the complex relationships within his growing harem, which includes characters who might be rivals in the normal Game of Thrones setting but are united by their connection to Jaune.
Jaune Arc would likely be an outsider at first, but his unique skills could quickly make him a player in the power dynamics. If he has his combat abilities from his own world, he could become a valuable asset to a particular house or faction. His sense of honor and justice might also set him apart, as the Game of Thrones world is often filled with self - serving characters. This could attract followers, including women who see his potential for positive change, and thus start to form his harem within the power structure.
One idea could be that your self - inserted character is a healer with a mysterious past. They end up in the middle of the war between the Starks and the Lannisters and start to form relationships with key characters from both sides, creating a harem of sorts. Another plot could be that your character is a time - traveler who tries to change the events of 'Game of Thrones' and in the process, attracts the attention of different characters who fall for them.
One idea could be that the male OC is a foreign noble who arrives in Westeros with unique skills and knowledge. He catches the attention of various female characters through his chivalry and different way of thinking. For example, he might be an expert in some form of magic not known in Westeros, and this intrigues characters like Daenerys, who is also associated with magic. Another plot could involve him being a healer, and as he travels through the Seven Kingdoms, he helps the sick and wounded, which endears him to many women, including those in positions of power like Margaery Tyrell. They see his selfless nature and are drawn to him.
One idea could be exploring what would happen if a minor character like Gendry had been secretly trained in magic. He could use his newfound powers to unite the smallfolk against the warring nobles. Another plot could revolve around a female knight from the North who disguises herself as a man to fight in the wars, and along the way, she discovers secrets about the White Walkers that no one else knows. Or perhaps a fanfiction where Daenerys and Sansa form an alliance much earlier and together they reshape the power dynamics of Westeros.
One idea could be exploring what would happen if a minor character, like Gendry, had a more central role in the fight against the White Walkers. He could lead a group of common folk and prove that the power doesn't always lie with the nobles.
A really cool 'Game of Thrones fanfiction' plot could involve the resurrection of some of the dead characters in a different way. For example, what if Ned Stark was brought back not as a vengeful wraith but as a wise advisor to a new king or queen? His honor and wisdom could shape the future of Westeros in a completely new direction. And it would be interesting to see how the other characters react to his return.
Perhaps a fanfiction where Daenerys Targaryen lands in Westeros earlier and forms an alliance with the Starks before the events of the main series. This would completely shift the political landscape and the fight for the Iron Throne. She could bring her dragons to help fight the White Walkers from the start.
An interesting plot could be that Naruto is transported to the world of Game of Thrones through some kind of magical portal. He quickly becomes involved in the power struggles as he tries to find a way back home. Along the way, he meets various female characters who are drawn to his courage and his strange powers. These women form a harem around him, and Naruto has to balance his relationships with them while also trying not to get caught up in the deadly Game of Thrones politics.
One idea could be that Oliver Queen somehow gets transported to Westeros. He could use his archery skills to survive in the dangerous world. Maybe he'd join a faction, like the Night's Watch, and teach them his modern combat techniques.
One idea could be exploring what would happen if a minor character, like Gendry, became the King of Westeros. He has a claim to the throne through his Baratheon blood and his time with the Brotherhood without Banners could give him a different perspective on ruling. Another plot could involve a female character, like Brienne, leading a new order of knights that are dedicated to protecting the realm in a more democratic way. Or perhaps a story where the White Walkers and the humans form an uneasy alliance against a new, even greater threat from Essos.
