Well, having a powerful Charmander would give Ash a head start in his journey. He may become a bit more overconfident at first, but as he faces different challenges, he will learn that power alone is not enough. This would lead to a more complex character development. He would need to balance the Charmander's power with strategy and compassion for other Pokemon. Also, his relationship with the Charmander would be different from his relationships with his other Pokemon in the original series. He might rely on it more initially, but then learn to trust his other Pokemon as well as they all contribute in different ways to his battles and growth as a trainer.
Ash would likely be more confident from the start. Since he has a powerful Charmander, he might be more eager to take on stronger opponents. He would also have to learn how to handle a Pokemon with such great power, which could make him more responsible.
It would change his journey a great deal. Firstly, having a shiny Charmander would make him stand out more. Other trainers would be more likely to challenge him, either to prove themselves against someone with a rare Pokémon or to try and get his Charmander. Also, trainers with more experience might offer to help Ash train his shiny Charmander, which could lead to new training techniques. In Pokémon contests, his shiny Charmander would be a show - stopper, giving him an edge in those aspects of his journey as well.
In this fanfiction, Ash could develop better strategic thinking. Froakie's abilities would force Ash to come up with new battle plans. He'd study Froakie's moves and how they can be combined in different ways, thus enhancing his strategic skills. He may also become more empathetic towards Froakie as he discovers more about its nature and feelings, leading to a more well - rounded character.
One possibility is that the Charmander was found in a special place, like an ancient ruin. It has powers that are not fully understood at first. Ash, being the determined trainer he is, decides to figure out how to use these powers to their full potential. As they journey together, they face challenges not only from other trainers but also from mysterious forces in the Pokemon world that are interested in the Charmander's power. This fanfiction could be full of adventures, growth, and the development of a strong friendship between Ash and his Charmander.
Ralts could make Ash more empathetic. Since Ralts is a very sensitive Pokémon, Ash would need to be more in tune with its feelings. This would cause him to be more understanding of all Pokémon in general.
His relationship with Pikachu might become more competitive at first. Since Ash already has a strong starter in Charmander, Pikachu might feel the need to prove itself more. But over time, they could learn to work together better, with Pikachu using its electric attacks to complement Charmander's fire attacks in battles.
Ash's character would likely become more confident. Starting with a Charizard, which is a very powerful Pokémon, would give him an edge in battles. He would also become more patient as Charizard can be difficult to train at times. For example, when Charizard refuses to listen, Ash would have to find new ways to communicate and gain its respect.
Ash would likely become more responsible. Since Dratini is a relatively rare and potentially powerful Pokémon, he'd have to take extra care. This could make him think more before acting in battles and other situations.
One possible plot could be that Ash finds Charmander much earlier than in the original series. They could form a really strong bond quickly and start training in a different way. Maybe they focus more on speed and stealth rather than the usual battling approach at first.
Well, if Ash starts with an Ekans, his team dynamic would be very different. Ekans is a snake - like Pokemon, and it might not get along well with some of the more energetic or flighty Pokemon at first. For instance, Pikachu might be a bit wary of it since they are so different in nature.
Ash's character development is quite significant. At first, he might be a bit over - eager and not fully understand Charmander's needs. But as they spend time together, he learns patience. He realizes that Charmander can't always be pushed to its limits right away. His confidence also builds. When they win battles together, he starts to believe in his own abilities more. And his sense of loyalty deepens as he would do anything to protect Charmander.
