His character could develop a more gentle side. Mew is often associated with kindness and playfulness. As Ash becomes a Mew fan, he might start to exhibit these traits more. For example, he could be more patient with his other Pokémon and more understanding of their needs, rather than just focusing on winning battles.
At first, Ash might be in awe of Mew. He has heard so much about this rare and powerful Pokémon. Mew, on the other hand, would be curious about Ash's determination and his bond with his Pokémon. As they spend time together, Ash would start to learn from Mew's unique abilities and wisdom. Mew might show Ash how to communicate better with his Pokémon on a deeper level. Their relationship could develop into a sort of mentorship, with Mew guiding Ash in his Pokémon training journey.
Often, it starts with Ash being in awe of Mew's rarity and power. Mew, seeing Ash's pure heart, decides to approach him. Then they start to trust each other more as they face challenges together, like saving a group of Pokemon from a natural disaster.
His character could become more stealthy and calculating. No longer just relying on brute force, he would learn to plan his moves carefully. For instance, he might study his targets' routines for days before making a move.
Issei's sense of morality could be tested. If he has dragon instincts like a desire for wealth or dominance, he'll have to decide whether to give in to them or resist. This inner struggle would shape his character development. For example, he could choose to use his new powers for good, protecting the weak instead of using his strength to bully others.
He would also develop a deeper sense of honor. In the ninja world, honor was important but in a different way. As a knight, he would understand the significance of a knight's word and the consequences of breaking it. This would make him more cautious in his actions and decisions.
His character would become more spiritual. Instead of just focusing on physical combat as a ninja, he'd start to understand the importance of spiritual power in exorcism. This would make him more well - rounded.
At first, his friends might not believe it's Ash. But when he starts to show his usual personality traits, like his determination and kindness, they would start to accept it. They would then start to think about how they can use Ash's new form to their advantage. For example, they could use his ability to fly as Mew to reach places they couldn't before, or his psychic powers to sense danger from afar.
One possible plot could be that Ash has a strange encounter with a Mew. Maybe he discovers a hidden power within himself that is related to Mew. This new power could attract Mew to him, and they form an unexpected bond. Ash then has to learn to control this new power while also facing challenges from other trainers who are jealous of his newfound connection with the rare Pokémon Mew.
His character would become more complex. Naruto is known for his positive and determined attitude. But as Riser, he might have a more egotistical side. He could start to show off his new powers more and be less concerned about the feelings of others at times.
Jason Todd's character would likely become more complex. He has his own history of violence and death, but as a Batman fan, he would be influenced by Batman's no - kill rule. This internal struggle between his old ways and the new inspiration from Batman could lead to a lot of character growth. He might start training harder, not just to be a better fighter, but to be a better hero like Batman.
