I'm not sure about the specific plot of that particular fanfic. It could involve Ash having an epic battle with a Gardevoir and its trainer. Maybe there are some unique strategies, new Pokemon abilities introduced, or a deep backstory for the trainer and Gardevoir that leads to the confrontation with Ash.
Ash is the central character that we all know from the Pokemon series. He's always eager for new battles and challenges. The trainer in this fanfic is also important. This person might be a local expert in Pokemon training, with Gardevoir being their prized Pokemon. Gardevoir, with its elegant appearance and strong psychic powers, will play a major role in the story as it battles Ash. There could also be other minor characters in the background, like other Pokemon that Ash has or some bystanders watching the battle.
Some fanfictions explore the idea of the two Pokemon learning from each other. After the battle, whether it's a win, lose or draw, they might exchange some sort of knowledge or experience. Maybe Greninja learns how to be more aggressive from Charizard X, or Charizard X learns about agility from Greninja. There are also plotlines where the battle is a test of friendship or loyalty between the Pokemon and their trainers.
There could be unfinished business between them. They might have a shared goal that they haven't achieved yet. Greninja's return to Ash in the fanfiction could be to finally complete that goal, whether it's winning a particular Pokemon tournament or saving a certain place from destruction.
In this fanfiction, Greninja could meet Misty. She's often associated with Pallet Town and she has her own set of water - type Pokemon. Their meeting could be interesting as Greninja is also a water - type Pokemon. They might exchange stories about their battles and experiences with water - type Pokemon.
Once upon a time, Greninja was in a deep, dark forest. It was on a quest to find a special crystal that was said to enhance its water - based attacks. As it leaped from tree to tree, it sensed a strange presence. Suddenly, a group of wild Pokémon emerged. Greninja readied itself for battle, its eyes gleaming with determination.
To develop their relationship realistically, communication is key. Since Gardevoir can be quite empathetic, it can pick up on Ash's emotions. Ash, on the other hand, should show respect for Gardevoir's power and intelligence. They could start with small moments of connection, like Ash sharing his food with Gardevoir, and gradually build up to more complex emotional bonds as they journey through different regions and face various challenges together.
Writers can start by giving Greninja a clear goal, like mastering a new move. Then, they can put obstacles in its way, such as tough opponents. Also, showing Greninja's growth in its relationship with Ash can be part of the arc.
There was a trainer called Mark who had a Gardevoir. Gardevoir was extremely loyal to Mark. During a journey through a snow - covered mountain, Mark lost his way. Gardevoir used its powers to create a warm shelter and found food for Mark. Mark was so touched. As time passed, they developed a unique bond. Mark started to notice Gardevoir's every little action and expression. Gardevoir also seemed to be happiest when it was with Mark. Their love story was a testament to the strong connection that could form between a trainer and a Pokémon.
A Gardevoir Visual Novel could be about various aspects. Maybe it delves into the origin of Gardevoir, its evolution process, and how it interacts with its trainers. It may also include some fictional scenarios that are unique to Gardevoir, like its psychic powers being used in a special way within the story of the visual novel.
