The reborn Ash could also change the perception of Pokémon in the world. If the OC was more environmentally conscious, they could promote a more sustainable way of living with Pokémon. This could involve reducing over - hunting of wild Pokémon for resources or protecting Pokémon habitats more effectively. This would not only affect the Pokémon but also the humans who depend on them in various ways.
They could impact it by introducing new training methods. For instance, if the OC had knowledge of modern sports training techniques, they could apply some of those concepts to Pokémon training. This might lead to Pokémon evolving faster or developing new moves. The Pokémon battles in the world would become more exciting and unpredictable as a result.
Pikachu would probably be very curious. It might zap the lightsaber a bit to see what would happen, and then be in awe of the bright blade. It could also get a bit protective of Ash when he wields the lightsaber, as if it senses the added danger.
One possible plot could be that the OC, now as Ash, has all the knowledge from their previous life. They might use this to train their Pokémon more effectively. For example, they could quickly figure out the best training regime for Pikachu, making it even stronger than in the original series. They could also have different strategies in Pokémon battles, using their prior knowledge of different Pokémon types and moves to their advantage.
It would change it a great deal. He'd be able to protect his Pokémon better. For instance, if they were in danger from a powerful enemy, he could use the Force to shield them.
Naruto's chakra control could be related to how Ash controls the energy flow in his Pokemon. Maybe he could use his chakra knowledge to enhance his Pokemon's attacks or defenses. Also, his ability to learn jutsus quickly might turn into an ability for Ash to quickly understand and train his Pokemon for new moves.
It could have a huge impact. His Pokémon journey might take some strange turns. He could be sent on quests by the hypnotist that have nothing to do with his original goals. His Pokémon might have to adapt to following these new, strange commands from Ash who is under hypnosis.
Mewtwo is also a common Legendary Pokémon in Ash - related fanfiction. Mewtwo's complex personality and its powerful psychic abilities make for interesting interactions with Ash. There can be stories about Mewtwo respecting Ash's bond with his Pokémon and joining him on a journey, or even testing Ash's worthiness.
If Ash was secretly a Pokémon, trainers might view Pokémon in a whole new light. They would see that Pokémon could be more like them, with complex emotions and motives. Also, Ash's relationships with other Pokémon and trainers would be re - evaluated. His Pokémon friends might see him as an equal rather than just a trainer.
Ash would probably be very curious about the Avengers' powers. He might ask a lot of questions and want to see them in action. In return, he could show them his Pokémon and how they fight.
If Ash releases Pikachu in the fanfiction, it could inspire other trainers to consider the well - being of their Pokémon more. They might start to think about whether their Pokémon are truly happy in the battle - centered lifestyle. It could also cause a stir in the Pokémon research community as they study the effects of a long - term partnership between a trainer and Pokémon being severed.
Pikachu would be very worried. It would stay by Ash's side constantly, using its electric shocks to keep him warm if he has a fever. His other Pokémon like Bulbasaur might use its vines to bring water or herbs to help soothe Ash's symptoms. Charmander could use its fire to keep the area around Ash cozy.
