Well, in Lysandre and Ash fanfiction, a common theme could be the power struggle. Given Lysandre's inclination towards power in the Pokémon universe, and Ash's own strength and determination, they could be pitted against each other in various ways. Maybe in some fanfictions, Lysandre tries to manipulate Ash into helping him with his schemes, seeing Ash's potential and popularity. Or perhaps it's about Ash trying to stop Lysandre from causing chaos. Also, the fanfiction could explore the emotional side of their relationship. How do they view each other? Is there any respect or admiration beneath their differences? These are all things that can be explored in such fanfictions.
One popular trope is the 'unlikely alliance'. Given their differences, it's interesting to see Lysandre and Ash team up. Maybe they have a common enemy that forces them to work together. Another trope could be 'redemption'. If Lysandre is portrayed as a villain initially, he might find redemption through his relationship with Ash. For example, Ash's positive influence could make Lysandre question his actions.
In the 'ash controlled by lysandre fanfic', the story could take many different directions. One possibility is that Lysandre's control over Ash could be part of a grander scheme. For example, he might want to use Ash's skills and reputation among Pokémon trainers to further his own goals, whether they be related to power, wealth, or some other self - serving objective. It could also delve into the psychological impact on Ash, how he copes with being under someone else's control, and whether he can break free. This could be a very engaging exploration of both characters and their relationship within the fan - created narrative.
Love and its complications could also be a theme. If the fanfiction takes a romantic turn, it might deal with the difficulties of a relationship between two such different characters. Sycamore's more positive and scientific nature contrasted with Lysandre's more complex and sometimes extreme views could create a lot of tension and drama in a romantic relationship within the fanfiction.
The plot could start with Lysandre finding a way to gain control over Ash, perhaps through some new form of technology or a mysterious power. Then Ash is made to do Lysandre's bidding, like stealing Pokémon or sabotaging other trainers. As the story progresses, Ash's friends might notice his strange behavior and start to investigate.
Ash is the protagonist, a young and determined trainer. He has a wide variety of Pokémon and a lot of experience from his travels. Lysandre is the antagonist. He usually has some sort of radical view, like wanting to reshape the Pokémon world in a way that benefits him or a select few. In fanfiction, their interactions can range from intense battles to more psychological confrontations.
