If Ash had chosen Bulbasaur as his starter. His connection with nature could be even deeper. He might have explored more grass - type Pokémon habitats. In battles, he could use Bulbasaur's status - changing moves like Sleep Powder to gain an edge. And his rivals would need to adjust their strategies when facing a grass - type starter - led team. This would change the whole dynamic of his Pokémon journey.
Suppose Ash started with Charmander. His team would have a strong fire - type presence from the start. He'd probably have a different relationship with Brock, who is a rock - type specialist. Since Charmander evolves into Charizard, which is very powerful, Ash would face different challenges in terms of controlling its power. His battles would be more focused on fire - type strategies and countering water - type opponents.
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.
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.
If Ash chose a different starter, the story would change drastically. For instance, if he had a water - type starter, his travel routes might be different as he'd seek out areas with more water - type Pokémon to train and catch. His battles against Team Rocket would also be different. A water - type starter could easily put out their fire - type Pokémon like Arbok and Weezing. This would force Team Rocket to come up with new plans to steal Pikachu (if Pikachu was still with him).
If Ash had a different starter like Bulbasaur in fanfiction, his team composition would change significantly. He might focus more on grass - type Pokemon to complement Bulbasaur's abilities. His travels through different regions could be affected as well. Maybe he would be more drawn to areas with more plant - life where Bulbasaur could thrive. Also, his interactions with other trainers having fire - type starters would be more interesting due to type advantages and disadvantages.
In a Pokemon fanfiction with Ash and Mewtwo, it could start with Ash encountering Mewtwo in an unexpected place. Maybe in a hidden forest where Mewtwo is observing the wild Pokemon. Ash, being his curious self, tries to approach Mewtwo. Mewtwo, initially hostile, realizes Ash's pure intentions and they start an unlikely friendship. This could lead to many adventures where Ash and Mewtwo face various challenges together, like battling against a new, powerful and evil Pokemon organization.
It could be a Pikachu. Since Pikachu is often associated with Ash and could be considered a special kind of 'first' pokemon for him in a different take of the story.
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.
In fanfiction, the relationship between Ash, Ho - Oh, and his starter can be very creative. Ash's starter might be a rare or unique one that has a connection to Ho - Oh's legend. Ho - Oh could see Ash's pure heart through his relationship with his starter and choose to guide them on their journey. This could lead to Ash uncovering secrets about the Pokemon world that are related to Ho - Oh and the starters' origins.
Well, 'different starter ash fanfiction' could refer to fan - made stories that start in an unusual way with the character Ash. It might be stories where Ash begins his journey in a completely new setting, like in a parallel Pokemon world where the rules are different.
