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 Sasuke might become more withdrawn and brooding due to the power and dark influence of the curse mark.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.
Another aspect is that the curse mark might be a catalyst for a new power dynamic. Sasuke could gain new abilities from the curse mark that Naruto initially envies. However, Naruto's growth would be in his understanding and compassion. Eventually, Naruto could learn from Sasuke's experience with the curse mark and use that knowledge to develop his own new techniques. This would level the playing field and create a more equal and complex relationship between them in the fanfiction.
Their friends might be initially afraid of them. Since the curse mark is often associated with dark power, friends like Sakura and Kakashi could be worried that Naruto and Sasuke might lose control. This could create some distance between them as their friends are not sure how to approach them anymore.
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.
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.
One possible plot could be that they get the curse marks from a new, powerful enemy. They then have to figure out how to control the curse marks together without losing themselves to the dark power. Maybe they go on a journey to find a way to remove the marks while also facing challenges from other villages who see them as a threat because of the marks.
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.
Well, without the curse mark, Sasuke may be less driven by the dark power it represents. He might focus more on his natural talents and training. This could lead to a more positive and self - reliant Sasuke, relying on his own skills rather than the boost from the curse mark.

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.
In fanfiction, the 'hot sauce punch' might be a turning point. It could make Sasuke realize that Naruto still has that goofy side and it might soften his cold exterior. On the other hand, if Naruto uses it out of anger, it could deepen the rift between them. For example, if Sasuke has just made a decision that Naruto strongly opposes, the punch could be a physical manifestation of his frustration.
As for the other Konoha 11 members, they might initially be skeptical. But as they see how Sasuke is changing for the better under Naruto's adoption, they start to include him more in group activities. They come to respect Naruto's decision and see Sasuke in a new light, which gradually strengthens the overall unity among them.
