Bruce Wayne is also important. Even though he's older, he still plays a significant role. He mentors Terry and provides him with the knowledge and resources to be Batman. Their relationship is a key aspect of the story. Additionally, characters like Max could also be main characters. She's Terry's friend and often gets involved in his adventures, sometimes helping him out with her hacking skills and general intelligence.
There might be new characters introduced in the fanfic as well. Maybe a new villain or an unexpected ally. However, the core will probably still revolve around Terry and Bruce. The fanfic could also focus on some of the supporting characters from the original Batman Beyond series, like Commissioner Barbara Gordon, who might have a different role or more influence in this fan - created story.
Well, Batman himself is likely to be one of the main characters. He would be the one trying to deal with the situation involving the splicers. There might also be some new characters created specifically for this fanfic that are related to the splicers, perhaps a leader among them or a scientist who created them.
Definitely Terry McGinnis. He's the central figure in Batman Beyond and in fanfic, his story can be told in so many different ways. He has to balance his normal life as a teenager with his superhero duties. Then there's Inque. She's a really cool and unique villain in the Batman Beyond universe. In fanfic, she can be made even more menacing or given a more complex backstory. And let's not forget Brother Eye. It's a super - interesting concept that can be explored in great detail in fanfic, adding new layers to the Batman Beyond world.
There could be some new characters who are splicers themselves. Maybe a lead splicer character who is trying to create a new world order for the splicers. This character could be complex, having both good intentions for his splicer kind but going about it in the wrong way, like causing chaos in Gotham.
Terry McGinnis is bound to be a main character. He is Batman in this future setting. His alter - ego as a young man trying to balance his normal life and his duties as Batman would be central to the story.
Well, in Batman Beyond Volume 1 Fanfic, there might be unique character developments. It could explore the relationship between Terry McGinnis (Batman) and his allies in more depth. Perhaps there are new sidekicks or different dynamics with the old characters like Bruce Wayne. It could also show how Terry deals with the legacy of being Batman in a more complex way.
Terry McGinnis as Batman is one of the main characters for sure. There's also likely to be Bruce Wayne, who mentors Terry.
Another character could be Terry's love interest. She could play a role in the twins' story, perhaps she has a connection to their past or she gets caught in the middle of their conflict with Batman Beyond, making the story more complex and engaging.
Ink could be a great main villain. He's a character from the Batman Beyond series known for his ability to manipulate ink - like substances. He could target Robin specifically, seeing him as a weak link in the Batman - Robin duo. His powers would pose a unique challenge for Robin to overcome.
Robin, in all his incarnations, is also a popular character in fanfiction related to Batman. He represents the sidekick aspect and the growth and development that comes with it. In Batman Beyond, Commissioner Barbara Gordon also features prominently in some fanfictions. Her connection to the original Batman era and her role in the new one can be explored in interesting ways.
I don't have enough information to know who the main characters in 'beyond time fanfic' are. It could be original characters created by the fanfic writer, or it might be characters from the original work on which the fanfic is based.
