It might be about Naruto facing a new kind of threat to the ninja world that the normal justice system can't handle. So, he steps up to create a new form of justice. This could involve him teaming up with some unlikely allies, like former enemies who also see the need for change. The fanfiction could explore how Naruto's concept of dark justice clashes with the values of the other ninja, and how he has to fight not only the external threats but also the internal resistance within the ninja community.
Obviously Naruto would be one of the main characters. But there could also be Sasuke. Maybe Sasuke and Naruto have different views on this new form of justice Naruto is trying to impose, which could create a lot of tension between them. Sakura might also be involved, trying to bring Naruto back to his old self or support his new cause depending on how the story goes.
In a Justice League fanfiction, Dark Naruto could be the anti - hero figure. He might not always follow the rules like the other members. His role could be to bring a different perspective on justice. For example, he might be more willing to use extreme measures to stop villains. He could also be the one who has a connection to a different kind of magic or power source that the Justice League has not dealt with before, adding a new layer of mystery and danger.
In fanfiction about the 'dark side of justice', authors often play with the concept of justice being misused or corrupted. It could be a hero who turns bad due to a flawed justice system. For example, in some stories, a vigilante might start off with good intentions but then go too far in their pursuit of justice, becoming more of a dictator in the name of justice.
Dark Naruto's powers would likely bring a new level of chaos to the Justice League. His Nine - Tails chakra is extremely powerful. In the context of the Justice League, he could potentially use it to enhance his physical abilities to superhuman levels, like being able to move at incredible speeds or having super strength. His ability to manipulate chakra might also be seen as a form of energy manipulation, similar to some of the powers of the League members.
Fanfiction in the 'Dark Justice Vengeance' realm can be really exciting. It often involves creating unique storylines that explore the themes of justice and vengeance in darker, more complex ways. Writers might take existing characters or create new ones to drive these stories forward.
Dark Robin in Young Justice fanfiction can bring a new level of drama. For example, his relationships with the other members of the team would be strained. His actions might be more morally ambiguous, making the other characters question whether they can trust him. It also gives writers a chance to explore different backstories for Robin that could lead to his darker persona, such as a personal tragedy or a betrayal.
In this type of fanfiction, magic could play a role in character development. For Naruto, experiencing a different type of power system like magic in the Young Justice world could make him question his own ninja way. He might start to adapt some of the magic concepts into his own fighting style. And for the Young Justice characters, learning about Naruto's 'magic' (chakra) could open their eyes to new ways of thinking about power and how to use it more effectively.
The setting is often a gritty and dangerous world. It could be a post - apocalyptic city or a crime - ridden underworld. This setting sets the tone for the themes of dark justice and vengeance. It's a place where the normal rules of society don't always apply, and characters have to take matters into their own hands.
Another theme is the over - zealous pursuit of justice that leads to unjust actions. Like a detective who frames an innocent person just to close a case quickly because he believes the person is guilty in his heart, even without solid evidence. This shows how the line between justice and vengeance can be blurred in such fanfiction.
