Who could be the main characters in 'joker becomes baby fanfiction' besides the Joker?

Batman is definitely one of the main characters. He is the Joker's nemesis, and their interactions drive a lot of the story.

Well, it could be about the Joker somehow getting transformed into a baby. Maybe he retains some of his villainous traits even as a baby, causing chaos in a comical way. For example, he might still have that evil laugh and try to play pranks on the other characters in the story.

In addition to the Joker, Harley, and their baby, there could also be other characters from the DC universe making appearances. For instance, Batman might show up as he is always on the lookout for the Joker's misdeeds. He could be a threat to the family unit in the fanfiction, or perhaps an unexpected ally in some situations. Also, other villains like Poison Ivy, who is Harley's friend, could play a role. Maybe she helps Harley take care of the baby or gives advice on how to deal with the Joker's wild behavior.

Batman would likely be a key character. He might be there to ensure that justice is served, even if it means going against the Joker's mind games.

Toph could be another main character. She has a unique perspective and her earthbending skills could be useful in various situations while dealing with baby Katara. For example, she could create a safe enclosure for Katara when they need to rest. Also, Gran - Gran might play an important role. She has a lot of wisdom and experience, and she could provide some insights on how to deal with a baby and perhaps some clues on how to reverse the transformation.

There's Harley Quinn. She has a complex relationship with the Joker and is often his accomplice. Another important character could be Commissioner Gordon. He's always trying to keep the city in order in the face of the Joker's chaos.

Harley Quinn is quite interesting. She's caught in the middle between her love for the Joker and her own sense of self. Commissioner Gordon is also important. He's the one who often has to deal with the aftermath of Batman and the Joker's battles and is a symbol of the law in Gotham.

The Joker and Batman are the key players. However, in some fanfiction, other characters from the Batman universe might also play important roles, like Harley Quinn who has a close relationship with the Joker, or Commissioner Gordon who is often involved in the Batman - Joker dynamic.

Obviously, Bella and the Joker are the main characters. Bella could be a completely original character created for this fanfiction, or she could be a reimagined version of an existing character from another story. The Joker, of course, is the well - known villain from the Batman universe.

Batman's allies are very likely. For example, Robin. The Joker would see kidnapping Robin as a great way to taunt Batman. Also, Commissioner Gordon might be a target as he represents law and order, which the Joker loves to disrupt.
