Some of the villains from the 'batman beyond' universe also become popular in the fanfiction. For instance, Blight. His character, with his radioactive powers and menacing presence, makes for great plot devices in the fanfiction. Writers can explore his backstory more, his motives, and his battles with Terry in different ways compared to the original series.
Terry McGinnis is definitely a popular character. He is the new Batman after all. His character often has a lot of development in the fanfiction as he tries to fill Bruce Wayne's shoes.
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.
Max is quite popular in 'Batman Beyond Unmasked' fanfiction. She is Terry's friend and often gets involved in his adventures. Her character provides an interesting contrast to Terry's more serious and secretive nature. Another popular character is probably Commissioner Barbara Gordon. She has a connection to the old Batman days and her role in the future Gotham is always an interesting topic in fanfiction.
Robin himself is often a very popular character. Fans love to explore his character arc and development.
One interesting concept could be the evolution of Gotham in the 'batman beyond' universe as depicted in the fanfiction. Maybe new villains or anti - heroes emerge that are unique to this take on the story.
In 'Batman Beyond Crossover Fanfiction', Terry McGinnis is a must - have. He is the main protagonist. Another popular character to include is Max, Terry's friend. She can provide support and a different perspective. Also, characters from other DC Animated Universes like Static Shock could be included. His electrical powers and street - smart attitude would contrast well with Batman Beyond's high - tech and more serious approach.
Obviously Superboy and Batman Beyond (Terry McGinnis) are must - includes. But also, characters like Max Gibson from Batman Beyond can add a lot. She's smart and tech - savvy, which can be useful when dealing with the mix of Kryptonian powers and high - tech in the fanfiction. Another popular one could be Krypto if you want to bring in some of Superboy's more traditional elements.
The Flash is also a favorite among fans for Justice League - related fanfiction. His super - speed can create exciting action scenes and unique plot twists. And for Batman Beyond, Commissioner Barbara Gordon is often a character of focus. Her relationship with Terry and her role in the new Gotham are rich areas for fanfiction.
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.
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.
