Well, in some fanfics, his curly hair makes him seem more approachable. For example, Hermione might start to see him in a different light and be less hostile. His new look can break down some of the barriers that were there in the original story.
In a lot of these fanfics, Draco's curly hair is a catalyst for change in his relationships. It can make him more relatable to characters like Ginny, who might then start to understand him better. Also, it can cause some of the older pure - blood families to view him differently. Some might see it as a sign of impurity, while others might think it gives him an air of mystery. All of these reactions to his curly hair can completely reshape the relationships he has with other characters in the fanfiction world.
His black hair in fanfiction can really shift how we perceive Draco. Normally, his blond hair is associated with his Slytherin elitism. However, black hair can give him a more brooding and intense look. It could imply that he has been through some sort of transformation, either physical or emotional. This new look can make him seem less predictable and more of a wildcard. It also might make other characters approach him differently, either with more caution or more curiosity.
I found a fanfic called 'Draco's Curly Secret'. In this story, Draco has been hiding his curly hair all his life because he's afraid of being made fun of. But then one day, he decides to embrace it and it becomes a symbol of his new - found confidence. The story has some really sweet moments and shows a different side of Draco that we don't often see in the original books.
With his mentors like Kakashi, they might see it as a sign of Naruto entering a new phase in his ninja development. Kakashi could offer different training methods or advice based on this new change. As for the villagers, some might be more fearful or superstitious about his new look, while others who already support Naruto might see it as just another quirk of their hero.
Some characters might be initially shocked or suspicious. His friends, like Sakura and Sasuke, could be worried that something bad has happened to him. However, over time, they would likely accept it. Enemies, on the other hand, might see it as a sign of new power and be more cautious. For example, Orochimaru might be intrigued and try to figure out what caused the change to see if he can use it for his own gain.
The professors would also be affected. Dumbledore would likely see this as an opportunity to bridge the gap between Gryffindor and Slytherin. Snape, on the other hand, would be in a difficult position. He has always had a complex relationship with Draco and a begrudging respect for Harry. Now, with them being twins, he would have to deal with a whole new set of dynamics in the classroom and in the overall wizarding world.
His relationship with Sakura could also change. Sakura might be both amazed and a bit worried about Naruto's new power. She could see it as a great asset in protecting the village but also be concerned about Naruto getting in over his head. This could lead to her being more protective of Naruto in a different way than before, perhaps trying to study more about psychokinesis to help him control it better.
It could change her relationship with Harry. Since Draco is often at odds with Harry, Luna being Draco's sister might make Harry initially more suspicious of her. But as he gets to know her better, he realizes that she is different from her brother in many ways.
Regarding his relationship with his friends, they would likely become more involved in his sister's life. They might start to see her as part of their group to protect. For instance, Shikamaru, known for his intelligence, could help Naruto plan strategies to safeguard his sister. Naruto's relationship with the Hokage, whether it's Tsunade or someone else, could also shift. The Hokage might give Naruto special permissions or resources to protect his sister, but at the same time, expect him to ensure that his sister doesn't become a liability to the village. This could create a complex dynamic between Naruto and the village leadership.
His relationship with Leia would be severely strained. She would likely be horrified that Luke has become heir to the Empire. Han might be more understanding, thinking that Luke has a plan to change things from the inside. His relationship with the Jedi spirits could also change, as they might be conflicted about whether to support him or not in his new role.
Their relationship with Hermione would be very different. Since they are twins, they might approach Hermione as a unit. Maybe they would both be more competitive for her attention, or they could work together to impress her with their combined knowledge.
