One interesting plot twist could be that Aegon has a secret alliance with a powerful magical being that no one in Westeros suspects. This being could help him in unexpected ways during his conquest, like using magic to disable the defenses of a stronghold just before Aegon's forces arrive.
Rhaenys Targaryen is another significant character. Her charm and diplomatic skills could be highlighted in the fanfiction. She might be the one who tries to win over the hearts of the people in the kingdoms they are conquering. For example, she could use her beauty and grace to make alliances with some of the minor lords who are initially hesitant to side with Aegon.
One interesting plot idea could be exploring Aegon's early days before his conquest. Maybe he has a secret love affair with a commoner that he has to keep hidden due to his family's expectations. This could add a layer of human vulnerability to his character.
One of the most interesting plot twists could be a character who was thought to be a minor noble rising to a key power figure. Maybe they discover a long - lost heirloom that gives them some sort of magical or political advantage. For example, a small - time knight finds an ancient sword that was once used by a great conqueror. This sword gives him the respect of the people and he starts to amass an army.
One interesting plot idea could be exploring Aegon's early years before the conquest. Maybe he had a secret love interest that was not of noble birth, which could have caused some internal family drama within the Targaryen clan. Another idea is to focus on his relationships with his sisters, Visenya and Rhaenys, and how their different personalities influenced his decisions during the conquest. For example, Visenya might have been more ruthless and pushed him towards harsher tactics, while Rhaenys was more diplomatic and tried to find peaceful solutions first.
In some fanfictions, there might be a focus on the reactions of the common people to Aegon's arrival. For example, how the smallfolk in different regions either resist or embrace the new order that Aegon is bringing. This can add a whole new layer of depth to the conquest narrative as it shows the impact on the ground level.
A possible plot twist could be that the dragons in Game of Thrones are actually the result of some ancient ninja jutsu from Naruto's world. Maybe a long - ago ninja experimented with a powerful jutsu that created these creatures. Another twist could be that Jon Snow has some hidden ninja blood in him, which gives him unexpected powers and abilities that no one in Westeros has ever seen before.
Well, perhaps a plot twist where the White Walkers are not the ultimate villains. Maybe they are being controlled by a more powerful and hidden force within Westeros. This would turn the whole 'fight against the White Walkers' narrative on its head. Also, a character like Tyrion Lannister could discover he has some sort of magical ability that has been dormant all his life, which would add a whole new layer to his character and his role in the story.
One interesting plot twist could be a character who was thought to be dead actually returns as a powerful force. For example, in some fanfictions, Ned Stark might come back with new knowledge or powers.
In some fanfictions, a plot twist might be that a long - lost relative of Jon Snow shows up during the Battle of the Bastards. This relative could have a powerful army or some unique ability that changes the course of the battle completely. For example, if it was a Targaryen relative who had a dragon egg that hatched during the battle. The sudden appearance of a dragon would completely disrupt the battle and give Jon's side an unexpected advantage.
In some 'Game of Thrones Do Over' fanfictions, Daenerys might form an alliance with the Starks much earlier. Instead of sailing to Westeros alone and facing challenges on her own, she teams up with them. This would create a powerful force against the Lannisters and other enemies, and also change the relationships between the different houses in unexpected ways.
