If Batman joins the Joker in a fanfic, the story might focus on Batman trying to reform the Joker from the inside. He could use his intelligence and skills to try and change the Joker's ways. However, the Joker might be playing his own games and trying to corrupt Batman instead. This back - and - forth struggle could be the main plot of the fanfic.

In such a fanfiction, the story might develop as Batman discovers secrets about Darkseid that he thinks he can use to his advantage. He could be playing a long - game, pretending to be on Darkseid's side while actually planning to bring him down. However, Darkseid is no fool and would likely test Batman's loyalty. Meanwhile, the rest of the DC universe would be in chaos as they try to figure out why Batman has turned and how to stop him if he's truly gone bad.
Well, perhaps at first, Batman tries to hide the fact that he has Joker's blood. But as time goes on, he starts to lose control. This could lead to him making mistakes during battles or even starting to cross the line in his pursuit of justice. His friends and allies would then have to figure out what's wrong with him and try to save him from the Joker's influence. Meanwhile, the Joker himself might be delighted to see Batman in this state and try to further manipulate him.

His rogues' gallery might be both confused and excited by this change, not sure whether to team up with him or oppose him.
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.
The Joker might use the holes in his head as a psychological weapon against Batman. He could play on Batman's sense of horror or disgust. Batman, on the other hand, might have a moment of hesitation when facing the Joker, which the Joker could exploit.

This could lead to some interesting confrontations where Batman has to balance his usual detective skills with his emotional reaction to the Joker's new appearance.
If Mewtwo joins Ash in fanfiction, the story development would be very interesting. Mewtwo might take Ash to places he has never been before, like the hidden lairs of other powerful Pokémon.

The story could start with Naruto finding Obito in a desolate place. Naruto would be curious and approach him. Then, they would exchange words, and Naruto would offer his help to Obito. As they interact more, they might face some small - scale battles together against rogue ninjas or other threats. This would build trust between them.
Batman would fit in by being the ultimate strategist. The Avengers sometimes jump into action without a fully thought - out plan. Batman's meticulous planning would force them to be more organized. He could also provide a more grounded perspective. Many of the Avengers have superpowers and deal with large - scale threats from outer space or magic realms. Batman, coming from the streets of Gotham, would remind them of the importance of protecting the everyday people.
