A really good fanfiction could be centered around a time when Nightwing doubts his place in Batman's life. Batman then has to prove to Nightwing that he is like a son to him. This could involve Batman opening up about his own fears and insecurities, which is not something he usually does. It would make for a very interesting read as it shows a different side of their relationship.
A fanfiction might explore the idea of Batman and Nightwing going on a 'father - son' road trip. They could be driving through Gotham and its outskirts, having deep conversations about their past, their future, and what it means to be a hero. Along the way, they face some small - scale villains and use their combined skills to defeat them, all while strengthening their father - son bond.
I would recommend 'Nightwing's Ascent'. This fanfic is amazing as it focuses on Nightwing's growth while still maintaining his connection with Batman. It has some really cool action scenes and emotional moments that make it a great read.
Well, one type of fanfiction could be about a young Nightwing still learning from Batman and then getting caught in a conflict with Slade. The story could show how Nightwing uses the skills he learned from Batman to outwit Slade. Another aspect could be the psychological battles. Since Slade is a formidable opponent, fanfictions can explore how Nightwing and Batman deal with his mind games, and how their own mental states are affected during these encounters.
One great 'batman x nightwing fanfiction' is 'A Bond Beyond the Cape'. It really delves into their complex relationship, showing how Nightwing's growth from being Batman's sidekick has shaped their dynamic. It has some really well - written action scenes and emotional moments that fans of the duo will love.
It can symbolize protection. Batman is the mentor, and when he carries Nightwing, it shows his instinct to keep Nightwing safe from harm, whether it's physical harm from villains or other threats.
One possible fanfic could involve a battle against a powerful villain. Nightwing might get injured while trying to protect Gotham. Batman then has to step in not only to defeat the villain but also to take care of Nightwing. He could use his advanced medical knowledge and resources in the Batcave to nurse Nightwing back to health.
I'm not sure who the absolute best is, but some popular ones might be those who have a deep understanding of the Batman and Nightwing characters. Maybe authors who have been following the comics for a long time.
When Batman is trying to figure out how to save Nightwing from a booby - trapped lair. Nightwing is giving Batman tips on how to disarm the traps because he's been in there longer. They are constantly communicating, with Batman trusting Nightwing's knowledge of the situation even though he's the one usually in charge. This shows a great role - reversal and cooperation between them that can be really engaging in fanfiction.
It's possible that such fanfiction exists. In the world of fanfiction, creators often experiment with different character dynamics. But in the traditional Batman and Nightwing relationship, Batman is more of a guiding figure to Nightwing. The idea of Batman being abusive is a deviation from the norm. It might be a way for some writers to add drama or explore the psychological impact on Nightwing if such a situation were to occur, but it's not in line with the general perception of their relationship.
In this fanfiction, often there's a power struggle. Nightwing, with his own set of skills and experiences independent from Batman, might oppose Batman on certain principles. Maybe it's about different approaches to crime - fighting. Nightwing could be more lenient while Batman is strict.
