Ash is often a popular supporting character. His connection to Pokemon and his adventurous spirit make him an interesting addition to a story about Mew's transformation. He might be the one to witness the transformation and try to help Mew understand what's happening. Another is Misty. Her feisty personality can create some great interactions with a transforming Mew. She could be initially scared but then grow to accept and even protect Mew. And Brock is also a favorite. His knowledge of Pokemon could be crucial in figuring out the reasons behind Mew's transformation.
Giovanni, the leader of Team Rocket, can be a very interesting character to include. His power - hungry nature and his past interactions with Mewtwo can add a layer of complexity to the story. There's also Misty. Her feisty personality and her skills as a water - type Pokemon trainer can bring a different dynamic to the fanfiction, especially if she teams up with Mew and Mewtwo or has some sort of rivalry with them.
A typical theme in Pokemon Mew transformation fanfiction is the concept of evolution gone wrong or right. If it's a wrong - turn evolution, Mew might transform into a monstrous form and have to deal with the consequences, such as being shunned by other Pokemon. If it's a positive evolution, it could become a sort of super - Mew with enhanced abilities for protecting the Pokemon world. And the theme of discovery also exists. Mew discovers new parts of itself during the transformation, like hidden strengths or mental capabilities.
Since 'lemon' often has inappropriate connotations in fanfiction, it's not easy to recommend popular ones in that regard. But if we consider general Pokemon Mew fanfiction, there are many popular ones that focus on Mew's powers and its role in the Pokemon world. However, it's important to stay away from any fanfiction that might involve adult - themed content related to the 'lemon' term.
Ichigo is often very popular. Her transformation into a Mew Mew and her strong - willed personality make her a favorite. She's the main character, so she's usually at the center of many fanfiction stories, whether it's about her relationships with the other Mew Mews or her battles against the aliens.
In this type of fanfiction, Sasuke could be one of the most popular characters. His cool and brooding nature would contrast with the more light - hearted Mew Mew characters. Also, characters like Ryou from Mew Mew Power, who has a bit of mystery to him, might attract a lot of attention. The combination of his knowledge of the Mew Mew world and his interactions with Naruto characters could make for some engaging storylines. And Naruto's friends like Shikamaru might also be popular as his laid - back yet intelligent personality could add a different flavor to the crossovers.
A common plot in Pokemon Mew toy fanfiction is that the toy has the ability to transform into a real Mew. This transformation could be triggered by a certain emotion or event. For instance, when the main character shows great courage in the face of danger, the Mew toy turns into the real Mew and helps them defeat a powerful enemy. Some fanfictions also explore the idea of the Mew toy being a part of a prophecy. The characters then have to figure out what the prophecy means and how the Mew toy fits into it to fulfill their destiny and bring peace to the Pokemon realm.
Well, often in these fanfictions, a plotline could be that Mew takes on a human form and becomes Ash's traveling companion. They might face challenges together that are different from his usual Pokémon battles. Maybe they have to solve puzzles in an ancient Pokémon ruin where only Mew's knowledge can help. Also, there could be a plot where Ash has to protect Mew from an evil organization that wants to capture it for its powerful genes.
One popular plot could be Fem Ash finding a rare Mew and trying to protect it from evil teams. Another might be a journey where Fem Ash forms a special bond with Mew and they help each other grow stronger. There could also be a plot where Fem Ash enters a Pokemon contest with Mew by her side, showing off their unique combination of skills.
Gladion could be a popular supporting character. He has a connection to Lillie in the original story, and in an evil Lillie fanfiction, he might be torn between trying to save her or having to oppose her. Another could be Hau. His carefree nature could contrast with an evil Lillie, and he might be one of the characters trying to stop her evil plans. And then there's Professor Kukui. He would surely notice the change in Lillie and could play a role in either understanding what made her turn evil or trying to put an end to her wrongdoings.
The main character is surely Ash. He is the one who is being betrayed. Mew is another important one. It might be that Mew is the cause, directly or indirectly, of Ash's betrayal. Then, Ash's Pokémon partners are likely to be main characters too. They might be confused or forced to side against Ash. And there could be some antagonists in the story, perhaps some evil trainers or organizations who are behind the plot to make Ash look bad and get betrayed.
