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.
The fanfic could start with Ash being in an unexplored area where Larvitar is a rare find. He's immediately drawn to its potential and decides to make it his starter. As they journey, Larvitar might have trouble adapting to the new environment and Ash has to find ways to help it. Along the way, they meet other trainers who are skeptical of Larvitar as a starter, but Ash and Larvitar prove them wrong by winning battles. Larvitar might also have some special abilities that are discovered during their adventures, which help them in difficult situations.
The relationship would likely start with Ash showing kindness and protection towards Larvitar. As they train together and face battles, trust would build. Larvitar would look up to Ash as a leader and friend.
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.
Maybe Ash decides to keep Larvitar as a special Pokémon in his team, and they go on adventures together. It could involve training Larvitar to become stronger and facing various challenges.
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.
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.
Well, in this fanfiction, perhaps Ash stumbles upon a Mudkip that was abandoned by its trainer. Feeling sorry for it, Ash takes it as his starter. They start their journey together, and the Mudkip has an unusual ability to communicate with water - type Pokémon. This leads to some interesting adventures as they encounter water - based mysteries and help other Pokémon in distress. They also have to prove themselves to other trainers who doubt a Mudkip as a starter.
