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.
It's possible that there is a character who has a personal vendetta against the unjust system and is on a mission to change it. This could be a journalist who is trying to expose the truth. There might be a police officer who is conflicted between following the rules and doing what is truly right in the context of this dark world. And there could be a powerful figure in the underworld who is trying to maintain the status quo of injustice, and these characters all interact in the story of the novel.
Well, the central theme might revolve around the idea that justice is not always straightforward. In this novel, it could be that justice is hidden in the dark corners of society, and the story is about the characters' journey to bring it to light. They might face many obstacles and moral dilemmas along the way.
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.
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.
