One great 'batman damian wayne fanfiction' is 'Robin: Son of Batman'. It delves deep into Damian's character, his growth from being a somewhat brash and overconfident young hero to a more well - rounded and empathetic one. It shows his relationship with Batman in a complex light, with the father - son dynamic being both a source of strength and conflict.
Grief is a very common theme. All the characters who were close to Damian, like Batman, Robin (if there's a new one), and the rest of the Bat - family, have to deal with the intense pain of losing him. Another theme is revenge. Batman might be driven to seek revenge against those he believes are responsible for Damian's death.
The Joker is always a classic choice. His chaotic and unpredictable nature would create a great contrast to Damian's more disciplined upbringing. It could also put a strain on the relationship between Batman and Damian as they deal with the Joker's madness in different ways.
Their relationship could develop through a series of adventures. For example, they might have to stop a powerful villain together. In the process, Damian's impulsive nature could clash with Thomas' more methodical approach. However, over time, they realize that they can complement each other. Thomas could help Damian think more strategically, while Damian could inspire Thomas to be more bold and take risks in their fight against evil.
Damian would likely become more cynical in the Batman Beyond setting. The darker, more technologically advanced yet decaying Gotham would harden his already tough personality. He'd probably be less trusting, especially with all the new threats that come with advanced technology.
One common theme is the clash of different ideologies. Batman is more about the gritty, street - level justice, while Wonder Woman brings in her Amazonian values. Damian Wayne often has to navigate between these two as he grows. For example, in some fanfictions, he has to decide whether to follow Batman's strict no - killing rule or be influenced by Wonder Woman's more lenient view on dealing with enemies in certain situations.
Archive of Our Own (AO3) is also a great place. It has a very organized tagging system. So if you're interested in a specific aspect of Damian Wayne's story, like his relationship with his mother or his time as Robin, you can easily find relevant fanfictions by using the tags.
One possible storyline could be Damian Wayne taking on the role of Batman in the Batman Beyond future. He might struggle with the high - tech gadgets and a more dystopian Gotham. Another could be Damian having to face off against an old enemy of Bruce Wayne's that has re - emerged in this new era. Maybe he has to deal with a new breed of super - villains created by the advanced technology of the future.
Perhaps a story where Damian gets kidnapped by an old enemy of Batman. Batman then has to race against time to save him, all the while reflecting on their complex father - son relationship. This could involve flashbacks to how Damian came into Batman's life and how they've grown together.
One possible scenario could be a time - travel or alternate universe situation. Thomas Wayne might be shocked to see Damian, his grandson, considering his own early death in the normal Batman timeline. He could initially be skeptical or even a bit hostile, thinking Damian is some sort of threat. But as they start to communicate, Damian could show his skills and determination, and Thomas might start to see the family resemblance not just in looks but in spirit.
