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.
A really cool 'Batman Beyond' fanfiction is 'Future of Gotham'. This one takes a look at the future of Gotham City itself, with Terry as Batman facing threats that could change the city forever. It has a unique take on the technology in the 'Batman Beyond' universe.
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.
In terms of Batman's growth, in the harem fanfiction, his personal relationships force him to reevaluate his loner - hero approach. He starts to rely on the members of his harem for emotional support and different kinds of help. This is a big change from the original where he was more self - reliant and solitary in his crime - fighting journey.
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.
