Sometimes other villains from the Batman Beyond universe might make appearances in the fanfiction related to Blight. They could either team up with Blight, adding more challenges for Batman, or they could be involved in some sort of power struggle within the criminal underworld that is affected by Blight's actions.
Batman is obviously one of the main characters. He's the central figure around which the tickling scenarios revolve. Robin is also commonly involved, as his relationship with Batman allows for different types of interactions, including tickle - related ones. The Joker is another character that might show up, as he loves to play mind games with Batman and tickling could be part of his devious plans.
One interesting aspect could be new interpretations of the Blight character. Maybe in some fanfictions, Blight has a different origin story compared to the original. For example, a fanfic might explore how Blight came to be in a more complex and detailed way, involving other characters from the Batman Beyond universe that were not directly related in the original.
Sasuke is often involved. Since Naruto and Sasuke have such a complex relationship, in this 'beyond godlike' scenario, Sasuke might be either a rival trying to match Naruto's new powers or an ally helping him control or use them. Another common character is Kakashi. He could be Naruto's mentor in understanding and managing these extreme powers.
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.
The Joker is often involved. He loves to push Batman to the brink of death in many fanfictions. His chaotic and unpredictable nature means he could come up with all sorts of devious plans to almost kill Batman, like luring him into a death - trap filled with his signature laughing gas. Another character is Ra's al Ghul. Since he has his own goals for Gotham and sees Batman as an obstacle at times, he might try to eliminate him in a more elaborate and long - planned way that leaves Batman on the verge of death.
Alfred is also quite common in these fanfictions. He serves as a connection between Batman and the younger characters. He might be the one who takes care of the young fan when they get caught up in Batman's business. And sometimes, Robin, especially a younger version of Robin, can be a key character, as he's closer in age to the young fan in 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.
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.
In Gohan snaps fanfiction, Gohan is the main focus. However, antagonists can play a big role too. Characters like Cell or Frieza could be in the story, if it's set in an alternate universe or a what - if scenario. For example, if Frieza comes back and attacks his family again, that could be the reason for Gohan to snap. And then there are his friends who will support him, like Krillin and Tien.
