One idea could be exploring Maxie's relationship with his father in his childhood. Maybe his father was a strict trainer who instilled in Maxie a love for Pokemon but also a sense of competition. Another plot could be that his father disappeared while on a Pokemon research mission, and Maxie is now on a quest to find out what happened to him. It could also be interesting to see how his father's actions or beliefs influenced Maxie's later decision to form Team Magma.
Perhaps Maxie's father was a Pokemon scientist who made a great discovery but was shunned by the scientific community. Maxie, in an attempt to prove his father right, takes extreme measures with Team Magma. The fanfiction could focus on how Maxie's loyalty to his father's ideas drives him to make certain choices in the Pokemon world. This could include his battles, his search for legendary Pokemon, and his interactions with other trainers and teams.
One plot idea could be that May discovers Maxie's plans for Team Magma early on. She then tries to stop him by using her Pokémon skills in a series of battles. Another idea is that Maxie realizes the error of his ways through interactions with May. Maybe he sees her bond with her Pokémon and starts to question his own motives. A third plot could involve May and Maxie having to team up against a greater threat, like a powerful and mysterious Pokémon that is causing chaos in the region. This forces them to put aside their differences and work together.
Another plot could involve her going on a journey to discover her own identity outside of being Maxie's daughter. Along the way, she meets different trainers and Pokémon, and she has to deal with the prejudice some have towards her because of her father. She could also discover some long - lost secrets about her family that change her perspective on everything.
A plot could involve May and Maxie being forced to team up during a strange natural disaster in Hoenn that affects both Pokémon and humans. They initially don't trust each other but gradually learn to work together. Also, perhaps May's Pokémon get accidentally influenced by Maxie's experiments, and she has to find a way to reverse it while dealing with Maxie.
Maybe Ash's father was part of an ancient Pokemon - protecting clan. In the fanfiction, Ash starts to have strange dreams about his father and these dreams are actually memories passed down through some sort of psychic Pokemon connection. This leads him to search for the clan and learn more about his heritage and his father's role in it. It could involve Ash having to prove himself worthy to the clan.
One possible plot could be Flannery trying to understand her father's motives in Team Magma. She might initially be against his actions but as the story progresses, she discovers there are deeper reasons behind what he does. For example, Maxie might be trying to create a better world for his daughter in his own twisted way.
Sure, there are likely fanfictions with this concept. In the Pokemon world, fans love to create their own stories and tweak the relationships between characters. Maxie being Flannery's father can open up a whole new set of story possibilities. For example, it could change how Flannery views the actions of Team Magma, which Maxie is associated with. It could also explore how Flannery's character traits might be influenced by her father. But it really depends on the creativity of the fanfiction author.
One idea could be the main character being reborn as a Pikachu and having to navigate the world with its electric powers while making friends with other pokemon. Another could be being reborn as a Eevee and having the unique ability to evolve into any form at will, which causes both envy and admiration among other pokemon. Maybe the reborn pokemon has memories of being a human and uses that knowledge to outwit trainers and other threats.
The complex character of Maxie. He has such strong beliefs and motives that make for great storytelling in fanfiction.
When writing a Pokemon Maxie father fanfiction, start with a clear concept. Are you focusing on their family bond, or how his father's legacy affects Maxie? Then, build a believable world. Incorporate Pokemon battles, training, and the different regions. For the relationship between Maxie and his father, you can use dialogue to show their emotions. For example, if Maxie is angry with his father for leaving, have a heated conversation. Don't forget to add a resolution to the story, whether it's Maxie forgiving his father or going his own way.
An interesting plot for a Pokemon Conquest fanfiction could be a tale of a trainer who loses their memory but still has an innate connection with their Pokemon. As they journey through the kingdoms, they slowly start to regain their memories through their Pokemon battles and interactions. Another plot could involve a forbidden love between trainers from rival kingdoms, and how they try to keep their relationship a secret while also dealing with the pressures of their kingdoms' expectations. You could also create a fanfiction where a new type of Pokemon emerges, and all the kingdoms are vying to be the first to tame and control it, leading to a series of intense battles and political intrigue.
