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 relationships would change too. He would no longer have the same kind of relationships he had with his ninja comrades. Instead, he would form bonds with knights who have different values and upbringings. He would learn to respect their traditions and in turn, they would respect his unique ninja - knight hybrid abilities.
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.
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.
Naruto's character would take a dark turn. He might become more cynical. Instead of his usual optimistic self, he would view the world with suspicion. His sense of justice would be warped. He could start to believe that power is the only thing that matters, not the bonds he once held dear. His sense of humor might disappear as well, replaced with a cold and menacing demeanor.
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.
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.
Naruto's character would develop in various ways. He'd become more open - minded as he experiences the digital world. His usual determination would be applied to understanding Digimon and their world. He might learn to be more patient too, since Digimon might not understand his ninja ways immediately.
Naruto's character would likely become more confident. With the power of the Kyuubi, he would know he has the ability to face stronger foes. He might also become more independent, as he has to learn to control this new power on his own. His sense of responsibility would grow as he realizes the potential harm his new form could cause if not controlled properly.
Naruto would probably develop a deeper understanding of life and death. He's used to fighting to protect life, but now he's on the other side. This new perspective could make him more empathetic towards all beings. He might also become more mysterious to those who knew him before, as his new role would be so different.
His character would likely become more complex. He might start to question his values. As a fallen angel, he may have to face darker aspects of himself. For instance, he could struggle with newfound aggression that comes with his powers.
