He could be using it to improve his writing skills. By analyzing his old fanfiction, Ash can identify areas where he has grown as a writer and areas that still need improvement. For example, he might notice that his descriptions of Pokémon battles were a bit simplistic in the past and work on making them more detailed and exciting in his current writing.
To inspire new ideas for his Pokémon adventures.
It could be Pikachu. Since Pikachu has been with Ash from the very beginning and is his most iconic Pokémon. It's very likely that in Sinnoh fanfiction, Pikachu would be frequently used as it has a strong bond with Ash and is also very powerful.
Ash probably uses creative training methods in the fanfiction. For example, he might have his Pokémon practice moves in tandem with each other. Pikachu and Charizard could work together on a combo move, which not only strengthens their individual skills but also their ability to cooperate in battles.
It could mean that Ash, in the context of fan - created Pokémon stories (fanfiction), utilizes all the Pokémon available to him within those fictional narratives. For example, he might use different Pokémon for various battles, quests or adventures as written by the fanfiction authors.
Ash's deep knowledge of Pokémon means he can spot the similarities and differences in fanfiction. He can see when a fanfiction accurately portrays a Pokémon's nature or when it goes off on a tangent. His real - world Pokémon experiences act as a reference point. So, if a fanfiction has a Charizard with an odd behavior, he can compare it to his own experiences with Charizard and thus understand the story in that context.
Well, it could mean that Ash is drawing on the creativity and unique ideas from the old fanfiction. Maybe he finds inspiration in the different storylines and character interpretations that were present in those works. It might also indicate a sense of nostalgia, as the old fanfiction could represent a bygone era of Pokémon fandom.
Ash could be foraging for berries. Berries in the Pokémon world have various uses, such as healing Pokémon or enhancing their stats. Fanfiction often depicts Ash exploring different regions in search of unique and powerful berries to help his Pokémon in battles and on their journey.
Yes, he might. Ash has extensive knowledge of Pokémon in the main series. Since fanfiction often builds on the existing Pokémon lore, he could potentially understand it. He's familiar with different Pokémon types, their behaviors, and the general Pokémon world, which are common elements in fanfiction.
He might use them because they are his tried and true companions. Ash has a strong bond with his old Pokémon, and in the Kalos region, he wants that familiar support.
At first, his Pokémon would be startled. They've always known Ash as a human. But then, they would start to adapt. Some Pokémon, like Squirtle, might try to play with Ash in his new form, thinking it's a new kind of game. However, his more loyal Pokémon, like Greninja, would be determined to find a way to turn Ash back. Greninja might use its special bond with Ash to try and communicate with him on a deeper level in this new form, to understand what happened and how to reverse it.
