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.
Well, it's fascinating because it allows for a reimagining of the Batman mythos. The deaged Batman has to face the challenges of Gotham in a different way. He might have to rely more on his wits and less on his established reputation. This can lead to some really creative storylines, where he has to prove himself all over again and develop his skills and strategies in new ways.
One common theme is the struggle to adapt. When Batman is deaged, he has to adapt to his new body and limitations. Another theme is the re - evaluation of relationships. His friends and foes might see him differently, and he has to navigate those changes.
In certain 'Batman deaged fanfiction', the story could revolve around how the deaged Batman adapts to modern technology. Since he's from an earlier time in his life, the advanced gadgets and surveillance systems of Gotham in the fanfic might be completely new to him. This leads to some humorous and also action - packed scenes as he tries to master them while still fighting crime.
One great deaged Batman fanfiction is 'The Young Dark Knight's Return'. It shows Batman as a child, facing challenges in a new and interesting way. The author does a wonderful job of maintaining the essence of Batman even in his deaged state.
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.
One character that would be really interesting to pair with deaged Loki is Doctor Strange. Strange could be the one to help Loki figure out how to reverse the deaging process or use his new situation to his advantage. Also, if we consider the Avengers, Natasha Romanoff could be paired with deaged Loki. She could teach him some skills that he might not have learned in his original upbringing, like stealth and espionage. And Steve Rogers could also be a good match. Rogers' sense of honor and justice could have an impact on deaged Loki and maybe even inspire him to be a better person.
Weiss would probably be very protective at first. She has always had a bit of a mother - hen side to her, and seeing Ruby in a more vulnerable, deaged state would bring that out. She would likely try to keep Ruby out of trouble and make sure she was taking care of herself.
Well, a lot of 'deaged Hermione' fanfics have the theme of redemption. It could be that in her older self, she made some mistakes that she now has the chance to correct in her deaged state. And of course, the theme of mystery is there too. How she got deaged and what the consequences will be are often elements of mystery in these stories.
Time - related themes are quite common too. Sometimes the deaging is linked to time - travel, and this can lead to themes of changing the past or understanding the importance of events in a new way. There can also be a theme of growing up again, but in a different way this time. Harry might learn things he missed the first time around while growing up, and this new growth process can be a central theme in many deaged Harry fanfictions.
