Sure was. Batman Beyond was indeed a comic that explored the adventures of a new Batman in a dystopian future. It had unique storylines and art styles that attracted many fans.
One of the best is 'Return of the Joker'. It delved deep into the complex relationship between Batman and the Joker, even in this futuristic setting. It was dark, full of twists, and really explored the legacy of the original Batman - Joker dynamic.
There's no fixed number of Batman Beyond comics. It's a constantly evolving field. Different story arcs and special editions contribute to the total, making it difficult to provide a precise count.
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.
Well, it could be about the hidden aspects of Batman's life in the 'Batman Beyond' setting once he's unmasked. For example, his relationships might change drastically. His family could be in danger more than ever. And it might also show his struggle to maintain his normal life while dealing with the new situation of being unmasked.
One idea could be Harley Quinn getting a fresh start in the Batman Beyond era. Maybe she tries to reform and uses her unique skills to help the new Batman. She could team up with him to take on a new villain that's causing chaos in the future Gotham.
