Another great fanfiction idea is a time - travel one. Ash and Mars are sent back in time to the early days of Pokemon training. They have to adapt to the different rules and limited technology. This forces them to work together and also gives them a chance to see how Pokemon training has evolved over time.
There could be a fanfiction where Ash and Mars get lost in a mysterious, uncharted region. Along the way, they encounter rare Pokemon and have to rely on each other to survive. Ash's knowledge of Pokemon behavior and Mars' cunning would be put to the test as they find their way out.
One interesting aspect could be their backstories in the fanfiction. For example, how Saturn and Mars came to be part of their respective organizations. It could be that they had difficult childhoods that led them to their current paths. They might also have secret motives that are revealed as the fanfiction progresses.
In some fanfictions, baby Ash has a special connection with Pikachu right from the start. For example, he might communicate with Pikachu in a unique, baby - like language that only they understand. This creates really cute and heartwarming scenes as they explore the Pokemon world together.
One popular Ash and Mars fanfiction could be about their adventures in a region not shown in the anime. They might team up to face a new and powerful villain. For example, a story where they have to stop a dark wizard who is stealing Pokémon's powers in a mysterious forest.
Well, it could be about Ash traveling to Mars and Jupiter in the Pokemon world. Maybe he discovers new Pokemon species there. For example, there could be ice - type Pokemon on Jupiter because of its cold environment and fire - type Pokemon on Mars due to its hot nature. Ash could have to adapt his battle strategies to these new Pokemon and their unique abilities.
Sure. There's a fanfiction where Ash and Mars accidentally swap their Pokemon for a day. It's really fun to read as they struggle to handle each other's teams. Ash has to deal with Mars' more devious Pokemon, and Mars has to adapt to Ash's more friendly and straightforward ones.
There could be a fanfiction where Ash competes in a completely different kind of Pokemon tournament in the NX setting. Instead of the regular battles, it involves puzzles and challenges that require both the trainer and the Pokemon to work together in a more complex way. Ash would have to use his experience and quick thinking to succeed.
One interesting story could be about Ash's journey in the BW region with some unexpected Pokemon partners. Maybe he meets a rare and powerful Pokemon that no one has ever seen before in that region and they form a special bond. This could lead to him facing new and challenging Gym Leaders in unique ways.
One interesting story could be about Ash having to deal with the challenges of being pregnant while still trying to pursue his Pokemon journey. Maybe he has to balance training his Pokemon and taking care of himself during the pregnancy. Another could be a story where his friends support him through the whole process, like Pikachu being extra protective.
One interesting story could be where Ash sacrifices himself to save Pikachu from a powerful and evil Pokémon. In this scenario, his selfless act might lead to a great power awakening in Pikachu, who then goes on a journey to avenge Ash and protect the Pokémon world even more fiercely.
