The injured state of Joker can also be a chance for character exploration. Batman might see a more human side of Joker when he's injured and this can make Batman question his own methods of dealing with crime. It can also lead to a more complex relationship between the two characters as they are forced to interact in a different way than just the usual cat - and - mouse chase.
It can completely change it. Usually, there's this cat - and - mouse game between them. But when Batman hurts the Joker in fanfiction, it might make the Joker more vengeful. He could become even more obsessed with getting back at Batman.
In some fanfictions, an injured Joker might be found by Batman's sidekick. For instance, Robin could find the injured Joker and has to make a quick decision on what to do. This situation can lead to a lot of character development for Robin as he tries to figure out if he should follow Batman's principles or his own instincts. And it also adds a new dynamic to the Batman - Joker relationship as it involves a third party.
Perhaps Batman is injured in a trap set by the Joker. While he's injured, the other villains in Arkham Asylum sense his weakness and start planning a mass breakout. Batman has to use his wits and the help of Oracle to stop them from the confines of his Batcave, all while nursing his injuries.
Well, in these fanfictions, Stiles' injury can completely shift the plot. Firstly, it can introduce a sense of urgency. The other characters need to find a way to heal him quickly, which can lead them to new places or new characters who might have the cure. Secondly, it can affect the emotional arc of the story. Stiles might become more withdrawn or more determined, depending on how he copes with the injury. This in turn affects how the other characters interact with him and how the overall story progresses. It can also expose hidden strengths or weaknesses in the group as they deal with his injury.
Well, it could be about Batman trying to stop the Flashpoint Joker from causing chaos in Gotham. Maybe the Joker has a new and devious plan that only Batman can foil.
At first, Batman would be shocked and a bit confused. But quickly, his detective instincts would kick in. He would view the deaged Joker as a new and unexpected threat. He'd start gathering information about how the deaging occurred, in case it was part of a larger, more sinister plan. Batman would also be very careful not to underestimate the deaged Joker. He might try to isolate the Joker in a secure location to prevent him from causing chaos in Gotham. And he'd be constantly on the lookout for any signs of the Joker's old, devious self emerging from this new, younger form.
If Percy is injured, it can slow down the progress of the main quest. For example, if they're on a time - sensitive mission, his injury might force the group to take detours to find a healer or a safe place for him to rest.
In some fanfictions, a plot twist could be that Batman discovers the Joker has a family or a past that explains his madness in a more sympathetic way. For example, if it's revealed that the Joker was once an ordinary man who was experimented on by a corrupt organization, and Batman has to decide whether to still see him as a pure villain or something more complex. This could change the way they interact in the story.
One idea could be that the deaged Joker, now with a child's body but his same devious mind, tries to manipulate the younger version of Batman into believing they are friends while secretly setting up traps. Another could be that the deaged Joker's actions cause Batman to re - evaluate his own origin story and how it might be related to this new, younger - but - still - dangerous foe. Or perhaps the deaged Joker forms an alliance with other deaged villains in Gotham, creating chaos that Batman has to stop.
The plot could involve a new villain in Gotham who has a technology that can control people's minds. This villain starts to turn the citizens of Gotham against each other. Batman realizes that he needs the Joker's unique brand of chaos to break the pattern of the mind - control. The Joker, on the other hand, sees this as an opportunity to create even more mayhem. They join forces, with Batman trying to direct the Joker's actions to some extent. As they fight the villain, the Joker may come up with some out - of - the - box ideas to disable the mind - control device, while Batman focuses on protecting the innocent. But of course, their alliance is fragile, and at any moment the Joker could turn on Batman.
