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.
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.
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.
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.
One could choose not to support or promote such fanfiction. If you come across it, don't share it further. Also, positive engagement with the fan community by promoting more healthy and positive interpretations of the Batman - Nightwing relationship can help. For example, creating or sharing fanart and fanfiction that show their positive bond.
There's a fanfiction called 'Nightwing: Gotham's Shadow'. In this story, Nightwing is dealing with a new threat in Gotham that Batman is somehow oblivious to. It's an interesting take as it shows Nightwing's independence and his unique approach to protecting the city. It also has some great interactions with other Gotham characters.
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.
