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 fanfictions, Ash's shadow Pokémon transformation can be a really cool concept. It might happen due to some dark energy or a special encounter. For example, he could be influenced by a shadowy force while exploring an abandoned Pokémon facility. This transformation could give his Pokémon enhanced, but more aggressive powers.
One idea in fanfiction could be that Ash discovers a special item that enables his Charizard to mega evolve again, but into an even more powerful form. This new mega form might have different coloration and enhanced fire - based abilities. It could breathe a type of blue - flame that is hotter and more destructive, making it a force to be reckoned with in battles.
Ash could face some tough challenges in this fanfiction. He might have to train in harsh conditions to become a champion. For instance, training on a snowy mountain where Pokemon are stronger due to the environment. His team would need to adapt and grow. Maybe he gets a new Pokemon that is a bit of a troublemaker at first but later becomes a key player in his battles.
Ash could be a Pokémon trainer with a different starting point in this fanfiction. Born in 1987, by 1997 he might have already made a name for himself in local Pokémon battles. He could have a team of Pokémon that he rescued from difficult situations, like a Charmander that was abandoned by its trainer. His story could revolve around giving these Pokémon a second chance and proving that Pokémon don't need to be 'perfect' to be strong.
The impact of Ash's loss in the fanfiction could extend beyond just himself. His Pokémon might also feel demoralized. However, this could also be an opportunity for them to grow stronger together. Ash could start training more intensively, seek new training methods, or even try to catch new Pokémon to strengthen his team.
Ash develops by learning new strategies. In Pokemon Conquest, battles are different, so he has to adapt, which makes him more versatile. He also develops his relationships with new Pokemon, which broadens his understanding of different Pokemon types.
Pikachu could be a great choice as it has been Ash's iconic Pokemon. It would create a strong connection between the daughter and her father's journey. Another option could be a Eevee. Eevee has the potential to evolve into different types, which would offer a lot of possibilities for her journey and battles.
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.
Maybe it's a legendary Pokemon in disguise. In some fanfictions, legendary Pokemon often play important roles. It could give Ash the egg as a test or because it senses that Ash has a pure heart. Another possibility is that it could be a young trainer who can't take care of the egg anymore and trusts Ash to do a good job.
