If we consider the common growth pattern in the Pokemon series, Charmander evolving into Charmeleon could be an early evolution in the fanfiction. Since Charmander has a clear evolution line and Ash has a strong bond with it, it would make sense for it to be one of the first to evolve, perhaps due to a tough battle or a special encounter that accelerates its growth.
Ash would probably start with building a strong bond with Larvitar. He'd use his kind and patient nature, like he did with Pikachu. He'd feed it good Pokemon food, take it on adventures to gain experience, and train it in battles against weaker Pokemon first to build its confidence.
Ash's loss could lead to a change in his journey. Instead of just aiming for Pokémon battles and championships, he might focus more on self - improvement and understanding his Pokémon better. He could travel to new regions to learn different training techniques or seek out wise Pokémon trainers who can give him advice on how to avoid such losses in the future.
In many Pokemon fanfictions, Ash's father is often left as a mystery figure. Some fanfictions might create an elaborate backstory for him, perhaps making him a powerful Pokemon trainer in a far - off region. He could be someone who had to leave Ash and his mother for some noble or dangerous quest related to Pokemon.
Another of Ash's Pokemon like Charizard can have a proud nature in fanfiction. This pride can sometimes lead to conflicts with Ash, as it might not always follow his commands immediately. But it also makes Charizard a very determined fighter. When it finally decides to cooperate with Ash, it becomes an even more formidable force.
Pikachu is a very likely candidate. It's Ash's most iconic Pokemon and has a deep bond with him. Whenever Ash is in trouble, Pikachu often steps up to protect him.
If Red was Ash's father in a Pokemon fanfic, Ash might start with a Pikachu like in the original series, but it could be a special Pikachu that Red had some connection to. Maybe it was a Pikachu that Red had trained briefly or had a unique bond with.
Well, it could change the story in many ways. For example, he can directly understand Pokemon's needs and feelings. So he might be able to prevent some Pokemon from getting into dangerous situations more easily. He could also form stronger bonds with his Pokemon team, leading to more effective battle strategies as he knows exactly what they are capable of and what they are thinking.
One possible strongest team could be Pikachu, Charizard, Greninja, Lucario, Sceptile, and Infernape. Pikachu has been with Ash since the start and has a strong bond. Charizard is extremely powerful. Greninja has its unique form and great combat skills. Lucario is a very capable fighter. Sceptile was a strong addition to Ash's team in Hoenn. And Infernape showed great power in Sinnoh.
In some fanfictions, Pokemon Red can be depicted as Ash's father. Fanfiction often takes creative liberties with established characters and relationships. Writers might create this connection to add a new layer of depth to Ash's backstory or to explore how certain Pokemon training traditions could be passed down within a family.
