In some fanfictions, there could be original characters created by the author. These could be sidekicks, other scientists who oppose or assist Scarecrow, or even new villains or heroes in the Gotham City setting. They can bring new dynamics to the story and offer different perspectives on the conflict between Batman and Scarecrow.
Well, obviously Batman and Scarecrow are main characters. Batman is the hero trying to stop Scarecrow's evil plans.
One interesting fanfiction could be about Scarecrow's origin in the 'Batman Begins' universe. It might explore his early experiments with fear toxins in more detail than the movie did.
The main characters are Batman and Scarecrow.
In some fanfictions, Scarecrow is often depicted as a formidable foe to Batman. His fear toxins play a major role. Batman has to constantly overcome the extreme fears that Scarecrow induces. For example, in certain stories, Scarecrow may target Batman's deepest traumas, like the death of his parents, and use that to try and break him. This creates a very intense dynamic where Batman has to rely on his willpower and detective skills to outwit Scarecrow.
Fear is the most common theme. Since Scarecrow is all about inducing fear, it's often central in these fanfictions. Writers explore how Batman overcomes or is affected by the extreme fear that Scarecrow creates.
Dorothy, she is the brave girl from Kansas who finds herself in Oz. The Scarecrow, who is in search of a brain, is also a main character. The baby is the new addition that sets the story in motion. There could be side characters like Glinda the Good Witch who might offer guidance or assistance to Dorothy and the Scarecrow in taking care of the baby.
Batman, of course, is a main character. He is the central figure whose origin and early adventures are depicted.
One popular theme is the exploration of fear. Since Scarecrow is the master of fear, fanfictions often delve deep into how different characters, especially Batman, experience and overcome fear. Another theme is the battle of wits. Batman is a brilliant detective and Scarecrow is a cunning adversary, so their mental duels are a big draw.
The main features are the focus on fear and how Batman overcomes it. The Scarecrow's schemes are elaborate and the interaction between them is full of tension and drama. Plus, the backstories of both characters are explored to add depth.
Typically, these comics showcase Scarecrow's unique ability to manipulate fear, as well as Batman's detective skills to outsmart him. There's also a focus on the dark and gritty atmosphere of Gotham City.
Batman would probably first try to contain the situation. He'd use his resources as Bruce Wayne to spread misinformation or counter the revelation. He might also go on the offensive against Scarecrow to stop him from spreading the news further.
