The development of Damian is crucial. We should see him grow from a somewhat brash and angry kid to a more empathetic and team - player. Nightwing can expose him to different cultures and people in the fanfiction. This could lead to Damian having a broader perspective and better understanding of the world around him.
One interesting fanfiction could be where Nightwing takes on the role of Damian's mentor in a very strict yet loving way. He teaches Damian not just combat skills but also about morality and friendship. In this story, they might go on adventures together, facing villains that force Damian to grow under Nightwing's guidance.

There's a fanfiction called 'Nightwing and Damian: A New Alliance'. In this story, Nightwing takes Damian under his wing to teach him some of the more subtle aspects of crime - fighting. It has some really cool action scenes where they work together in perfect sync. Also, 'Damian's Redemption through Nightwing' is a good one. It delves into Damian's inner turmoil and how Nightwing helps him find a better path.
There are fanfictions where Artemis and Nightwing meet in a non - superhero context. For instance, at a coffee shop in Gotham. It's an interesting take because they don't immediately recognize each other out of costume. They start a conversation, and there's a lot of witty banter. Eventually, they figure out who they are and then have to decide whether to keep their new - found friendship or let it be complicated by their superhero lives.
One plot idea could be Nightwing teaching them his unique combat skills. He could have a special training session where he combines his acrobatic fighting style with elements from each of their own combat preferences. For example, incorporating Jason's more brute force when necessary, Tim's strategic thinking, and Damian's precision. Another idea is Nightwing helping them deal with their personal demons. He might sit down with Jason and talk about his past traumas and how to move forward. With Tim, it could be about his insecurities in the Bat - family. And for Damian, Nightwing could guide him on how to better fit into the family and society outside of just being a warrior.
Nightwing would likely be more empathetic with Jason. Given Jason's troubled past, Nightwing would be patient and understanding. He'd probably let Jason vent his frustrations and anger in a safe way. With Tim, Nightwing might be more of a mentor in terms of detective work. He'd share his knowledge and experiences to help Tim grow in that area. For Damian, Nightwing would be firm yet gentle. He'd enforce rules but also make sure Damian feels like part of the family and not just an heir to be molded.
He might meet a younger version of Alfred. Alfred has always been an important figure in the Wayne family and Damian could learn a lot from him, or even try to give him some hints about the future. Also, he could run into a younger Commissioner Gordon. Their interactions could be really interesting as Gordon is such an important ally of Batman.
Artemis is often portrayed as strong - willed and independent. Nightwing is more diplomatic and a team player. In some fanfictions, their personalities clash when Artemis wants to take a more direct, often aggressive approach to a problem, while Nightwing prefers to plan and work with others. For example, in a mission to rescue hostages, Artemis might want to charge in, while Nightwing wants to gather more intel first.
