A plot idea could involve Bulbasaur getting sick. Ash has to search far and wide for a special herb to cure it. Along the way, he meets other trainers who have had similar experiences with their starter Pokémon. This could also lead to Ash learning more about the unique bond between trainers and their Pokémon. It could be a story of friendship, determination, and the lengths one would go to save a beloved partner.
One idea could be that Ash's Bulbasaur gets separated from him in a strange, enchanted forest. As it tries to find its way back, it befriends some local Pokémon that are usually shy and elusive. Another plot could be that Bulbasaur discovers a hidden power within itself during a tough battle. Maybe it can suddenly control plants in a much more powerful way than before.
You can start by emphasizing its gentle nature. For example, show how it's always the first to comfort other Pokémon when they're scared. Also, highlight its loyalty to Ash. Maybe it refuses to leave Ash's side even in the face of great danger.
Another idea is Ash starting with a Bulbasaur. His journey could focus more on nature and plant - type Pokemon evolution. He might get involved in more environmental - related plots, like helping sick plants in the forest with Bulbasaur's powers.
In a fanfiction like this, the plot could revolve around the fact that the egg is the key to restoring balance in the Pokemon world. The legendary starter that hatches from it is initially weak but grows rapidly under Ash's care. However, there are forces at work that want to use the starter for their own evil gains. Ash has to team up with his friends and other Pokemon to fend off these threats. The story could also explore the relationship between Ash and the legendary starter as it grows, how they learn from each other, and how their bond becomes unbreakable.
One idea could be that Ash's Charmander gets separated from him in a mysterious forest. It has to find its way back while facing various wild Pokémon and challenges. Along the way, it discovers a hidden power within itself.
Well, the plot could involve Ash's unique starter being from a far - off region that was thought to be extinct. This starter could hold the key to an ancient mystery in the Pokemon world. As Ash travels with it, they encounter various challenges related to protecting this starter from those who would use its uniqueness for evil purposes. The starter might also have an ability to transform into different forms depending on the situation, like a more powerful form when facing a tough opponent.
One possible plot could be that Ash, instead of starting with Pikachu, starts with a Gastly. Gastly could use its spooky abilities to help Ash in battles. For example, it could use its ability to turn invisible to surprise opponents. It might also play pranks on Ash's rivals, like making them think they're seeing ghosts in the forest where they're camping.
One plot idea could be that Ash and Datini start on a journey to find a lost magical artifact. Along the way, they encounter various obstacles and have to use their combined skills to overcome them.
Maybe the fanfiction could focus on a trainer who gets a starter that's considered weak, like a Caterpie. But through hard work and a series of adventures, the Caterpie evolves into a Butterfree with extraordinary powers. The story could be about how they overcome the prejudice against starting with a 'weak' Pokemon and prove themselves in battles and Pokemon contests.
Well, you could have a fanfiction where the starter pokemon are in a competition not just against other pokemon but also against each other for a special prize. The trainers are caught in the middle, trying to balance their loyalty to their pokemon and the desire to win. Another interesting angle is a story where a starter pokemon is misidentified as a different type at first. Say, a Bulbasaur that looks like a Charmander because of a rare genetic mutation. This causes all sorts of confusion and challenges for the trainer. Also, a plot where the starter pokemon are reincarnations of ancient pokemon heroes and the trainer has to unlock their past memories to help them reach their full potential.
Ash could discover a hidden place where Ho - Oh resides. There, he finds a starter that has been abandoned. Ash decides to take it under his wing. Ho - Oh, seeing Ash's kindness, decides to guide Ash on his journey with this starter, giving him special powers or knowledge to help them grow together.
