Growlithe could be a very loyal addition to Ash's team. It might have a more protective nature compared to some of Ash's other Pokemon. This could change the way Ash approaches battles. Instead of always going on the offensive, he might rely on Growlithe to defend the team first. Also, the other Pokemon on the team might look up to Growlithe's courage, which could inspire them to be braver in battles.
Well, one possible plot could be that Ash finds a Growlithe that is injured in the wild. He decides to take care of it and train it. As they train together, they form a strong bond and face various challenges in the Pokemon world, like battles against Team Rocket who are after Growlithe for some devious plan.
It would likely bring a new level of harmony (literally) to Ash's team. Since Meloetta has musical powers, it could use its melodies to boost the morale of the other Pokémon on the team. For example, before a big battle, Meloetta could sing a song that makes Pikachu feel more energetic and ready to fight.
I'm not really into lemon fanfictions as they often involve inappropriate content. However, you can try searching on some well - known fanfiction platforms like Archive of Our Own. Just be sure to check the tags and ratings to avoid any unsavory material.
Since Espeon is often seen as an elegant and intelligent Pokémon, it might influence the behavior of Ash's more rambunctious Pokémon. It could teach them to be more strategic and calm. On the other hand, the other Pokémon might also introduce Espeon to a more fun - loving and adventurous side of life, changing Espeon's somewhat reserved nature a bit.
Well, I don't really recommend writing lemon fanfictions as they often cross the line of propriety. But if you must, focus on the emotional connection between Ash and Growlithe first. Build up their relationship in a deep and meaningful way before any sort of 'lemon' elements are introduced. And make sure to use euphemisms and not be overly explicit.
Ash could be shown as more empathetic towards Growlithe. His usual determination to be a great trainer could be combined with a newfound protectiveness over Growlithe. For Growlithe, it could be developed as being more curious about Ash's world and trying to adapt to human ways while still maintaining its Pokémon instincts.
Well, for one, Haunter has some really cool moves like Hypnosis and Dream Eater. When Ash catches it, his team's battle strategies would change. His other Pokémon would need to learn to work with Haunter. Also, Haunter's presence might intimidate some of the opposing Pokémon, giving Ash an edge in battles. It could also open up new exploration opportunities as Haunter might be able to access areas that other Pokémon on his team can't due to its Ghost - type nature.
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.
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.
Ralts could make Ash more empathetic. Since Ralts is a psychic - type Pokémon that can sense emotions, Ash might become better at understanding the feelings of other Pokémon and people. This could help him in his journey to be a better Pokémon trainer.
