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.
Another theme is identity. Characters with the curse mark may feel different from others, and the fanfic often explores how they come to terms with this new part of themselves. For example, they might question if they are still the same person they were before getting the mark. It's a complex exploration of self in the context of the Naruto world.
The curse mark could make Naruto more cautious. Since it's a dangerous and unpredictable power, he might think twice before acting impulsively as he usually does. For instance, in battle, instead of rushing in head - first, he'll consider the consequences of using the curse mark's power.
The curse mark can change their physical abilities. For Sasuke, it might enhance his speed and strength, but also make him more prone to losing control. Naruto, on the other hand, might develop new chakra - related powers because of his exposure to Sasuke's curse mark. For example, he could gain the ability to sense the curse mark's energy better.
There's also 'A New Path with the Curse Mark'. This fanfic focuses on a side character who gets a curse mark and how it changes their role in the Naruto universe. It shows their struggle to control it and use it for good, which is really interesting to read.
Well, one interesting aspect could be how Naruto overcomes the challenges brought by the curse mark. Maybe he has to learn to control its power without being consumed by it. For example, he might train with Jiraiya to find a way to turn the curse mark's dark energy into something useful in battle.
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.
In a fanfic scenario, Naruto might remove Anko's curse mark through his unique chakra. His chakra, known for its large amount and purifying properties, could potentially counteract the dark and corruptive nature of the curse mark. He might use a new jutsu he developed or a power-up that he gained during his training.
One interesting plotline could be Naruto struggling to control the power of the curse mark. It might lead him to make some unexpected decisions. For example, he could be tempted to use the dark power in the curse mark to defeat a powerful enemy quickly, but at the risk of losing himself to the darkness. Another plotline could involve Naruto trying to find a way to remove the curse mark without anyone's help, showing his independent and determined side. Maybe he goes on a journey to find a rare herb or a hidden technique that can get rid of it.
The removal of the curse mark might also change Anko's personality a bit. Since the curse mark was probably causing her some mental and emotional stress, without it, she could be more positive and open. This could lead to new friendships and alliances within the story. For example, she might start to get along better with some of the other Konoha ninjas who she had a bit of a distance from before because of the curse mark.
