The plot could revolve around Ash and Squirtle's first days together. Squirtle might be the only Pokemon Ash has at the start. They could enter a local Pokemon competition where Squirtle has to face tough opponents. Ash would need to strategize using Squirtle's water - based moves. Along the way, they meet a mysterious trainer who gives them a tip on how to improve Squirtle's speed, which helps them in future battles.
Friendship is also a big theme. The bond between Ash and Squirtle is explored deeply. They might face challenges together that test their friendship, like getting separated in a dangerous area but finding their way back to each other through trust and determination.
One possible plot could be that Ash discovers a Larvitar in the wild. He decides to make it his starter Pokémon. They then embark on a journey together, facing various challenges like battles against other trainers and wild Pokémon. Larvitar evolves over time, growing stronger with Ash's guidance and training.
Well, the plot could be about Ash starting his journey with a Pidgey as his first Pokémon. Maybe he faces challenges in training it to be strong enough to take on gym battles. He could encounter other trainers who underestimate him because Pidgey is a common starter, but Ash proves them wrong as he and Pidgey grow together.
One idea could be that Ash discovers a young and injured Mew. He takes it upon himself to nurse Mew back to health. During this time, they form a deep bond and Mew starts to teach Ash some unique Pokémon moves that are not commonly known. This new knowledge gives Ash an edge in his battles.
The plot could start with Ash getting Riolu as his starter Pokémon instead of Pikachu. Riolu might be a bit of a troublemaker at first, not fully understanding Ash's commands. But as they journey together, they start to understand each other better.
The plot could be that Ash's powerful starter helps him quickly become a top trainer in his region. He might breeze through gym battles with ease and attract the attention of powerful trainers and organizations.
Another option is to check out Pokémon - themed forums. Some dedicated Pokémon fans gather there and might have written or know of some great Ash Squirtle Starter fanfictions. You can engage with the community and ask for recommendations as well.
The plot could involve Ash and Chimchar facing a series of challenges in a new Pokémon league. They might encounter a powerful villain who has a special device that can nullify Chimchar's fire attacks. Ash then has to find a way to train Chimchar to use its other skills, like its speed and agility, to defeat the villain's Pokémon.
One possibility is that Ash discovers a young Rayquaza at the start of his journey. Maybe it's injured and Ash nurses it back to health. This could lead to a strong bond between them, and Rayquaza could become his most powerful Pokémon, helping him in battles against tough opponents like Team Rocket or other powerful trainers.
I don't know the exact plot as I'm not familiar with this specific fanfic.
