It's possible that as a doll, Misty discovers some hidden abilities or secrets. For instance, she could be able to communicate with certain types of dolls or inanimate objects in the Pokemon world. This could lead to a whole new adventure as she uses this new - found knowledge to help her friends, even in her doll form. The story could also involve some emotional moments as her friends struggle to accept her new form at first but then grow to love and protect her all the same.
Well, in such a fanfic, it could be a really interesting concept. Maybe it was due to some magic spell or a strange encounter in the Pokemon world. It might lead to various adventures where her friends in the Pokemon series try to find a way to turn her back into her normal self.
It could be a rogue Team Rocket member. Maybe they got their hands on a powerful new device that was meant to capture Pokemon but malfunctioned when aimed at Misty and turned her into stone instead. Now they're trying to cover up their mistake and keep Ash and the others from finding out the truth.
Well, they might have a friendly chat about their past adventures. Maybe they'll share stories of the Pokémon they caught and the battles they fought together.
Well, it might be that in a magical realm, the dragon, for some reason like disobeying the magic laws, is magically transformed into a doll. A young girl then takes the doll in and starts to notice strange things. As she delves deeper, she discovers the truth about the dragon and tries to help it regain its true form. There could be all sorts of magical creatures and challenges along the way.
Perhaps there's a special artifact. In the Naruto world, there are many powerful artifacts. If one of these artifacts was somehow connected to the Pokemon world, and Naruto interacted with it, it could trigger the transformation. For example, if an ancient scroll had the power to bridge the two universes and Naruto unknowingly activated it while on a mission, his body could start to change into a Pokemon. This would not only change his physical form but also his abilities, making for a really interesting fanfic plot.
Misty's Pokemon could be involved in a way where they are all captured by Team Rocket. Then Misty has to rely on her wits and some basic Pokemon - handling skills without her actual Pokemon. She has to find a way to free them. Meanwhile, her Pokemon are trying to communicate with other wild Pokemon in Team Rocket's base to create a sort of uprising. This would lead to a big showdown where Misty and her freed Pokemon take on Team Rocket and their own captured Pokemon.
The hair tie could have a magical property. For instance, it might allow Misty to communicate with a certain type of Pokemon that no one else can. This would make her a very special trainer. In the fanfiction, she could use this ability to solve problems, like stopping a group of wild Pokemon from attacking a village. She would be seen as a hero, all because of the hair tie on her wrist.
In the fanfiction, it might be that Misty has some sort of ulterior motive for stealing the Pokemon. Maybe she's being controlled by an evil force or she thinks it's the only way to protect the Pokemon from something worse. But still, Ash would not easily accept her actions and would likely fight to get the Pokemon back to its rightful place.
Well, if Misty joins Team Rocket in fanfiction, it would be a huge shock to the other characters. Her friends like Ash would be completely bewildered. Maybe she's been tricked into it somehow, like being deceived by Team Rocket's false promises. This could lead to some really interesting plot twists. For example, she might be used to set traps for Ash and the others, but deep down still have some good in her that causes internal conflict within Team Rocket.
Another possibility is that Ash wins the battle. Even though Misty has a new Pokemon, Ash's experience and the strong bond he has with his Pokemon could give him the edge. He might be able to quickly analyze the new Pokemon's weaknesses during the battle and use his Pokemon's attacks effectively to secure the victory.
