Well, it depends on the nature of the curse mark. If it's a dark magic - related curse mark, it might attract dark creatures towards Harry. This would put him in constant danger. He would have to be extra vigilant all the time. Maybe he would start to study more about curse marks on his own to find a way to get rid of it, which could lead him to some hidden secrets in the wizarding world that are related to curse marks.
The curse mark could change Harry's social status significantly. In the wizarding society, having a curse mark is often associated with something bad or dangerous. Some of his less - understanding classmates might start to bully him. His relationships with some of his friends could also become strained. Hermione, for instance, might be overly worried and try to force him into taking certain precautions that Harry may not be entirely comfortable with. And it could also make his encounters with Voldemort or other dark wizards more complicated, as they might see the curse mark as an opportunity to manipulate or use him.
It could be the result of a dark wizard's experiment gone wrong. Maybe some dark wizard was trying to create a new form of dark magic, and Harry accidentally got caught in the crossfire and ended up with the curse mark.
Well, in many cases, characters would face a lot of discrimination. However, some strong - willed characters in Harry Potter curse mark fanfiction might try to educate others about the mark. They would explain that just because they have the mark doesn't mean they are evil. They could give examples of how they are still the same person with the same values and loyalties. They might also try to find a cure or a way to control the mark's effects to prove to others that they are not a threat.
Naruto's relationship with Sasuke could be really affected. Sasuke, having his own experiences with dark powers, might see Naruto in a new light. They could either become more competitive as they both struggle with different forms of dark power, or they could bond over their shared experiences of having something that sets them apart from others.
The curse mark in the fanfiction could be a catalyst for fem Naruto's growth. It could bring out hidden aspects of her personality. Maybe it gives her access to new powers that she has to learn to control. This process of learning and the physical and mental changes caused by the mark would surely have a profound impact on her character development. She might become more cautious, as she realizes the potential danger of the mark, yet also more bold in her attempts to master it.
A possible plot in Harry Potter curse mark fanfiction is that the curse mark is actually a key to an ancient wizarding mystery. The main character, who has the mark, finds that they are suddenly being hunted by dark forces who want to use the mark for their own evil purposes. As the character tries to figure out what the mark means and how to protect themselves, they discover that it is linked to a prophecy. They must then decide whether to embrace the power that the mark might bring or find a way to destroy it completely, all while dealing with the normal challenges of Hogwarts life like exams and friendships.
In some fanfictions, the curse mark can be a source of tension. If Sasuke's curse mark makes him more aggressive or unpredictable, Sakura might be worried about him. For example, he could accidentally lash out at her during a training session. This would put a strain on their relationship as she tries to help him and he tries to keep his distance to protect her from the curse mark's influence.
In some fanfictions, the curse mark can initially drive a wedge between Naruto and Sasuke. Sasuke might become more withdrawn and brooding due to the power and dark influence of the curse mark. Naruto, on the other hand, would be worried about his friend but might not fully understand what Sasuke is going through. This could lead to some misunderstandings and arguments between them as Naruto tries to reach out while Sasuke pushes him away.
After absorbing the curse mark, Naruto's character development could take a significant turn. Firstly, he may face new challenges in controlling his emotions as the curse mark might have an impact on his temperament. He could become more impulsive or aggressive in battle. However, this also gives him an opportunity to grow. He has to learn to harness this new power without succumbing to its negative effects. It could lead to a more mature Naruto as he grapples with this new aspect of himself.
Naruto may become more cautious. With the curse mark, he realizes he has a power that can be dangerous. So he becomes more careful about his actions, not wanting to accidentally harm others with the mark's power.
There might be. Fanfiction writers sometimes like to take characters out of their comfort zones and explore darker or more extreme scenarios. But in the official 'Harry Potter' lore, Harry would never casually use the Killing Curse. It's a very serious and immoral spell in the wizarding world.
