Maybe the fanfic contains inaccuracies about the Pokémon world that Ash is a part of. If it misrepresents the relationship between him and Misty in a way that he doesn't like, he would reject it. Also, if the fanfic has a very dark or inappropriate tone that doesn't fit with Ash's positive and adventurous image, he would not be on board with it.
The possible reasons are many. Firstly, the fanfic might not be in line with the official Pokémon storyline that Ash is accustomed to. His character development and relationship with Misty are important aspects in the official story. If the fanfic distorts these elements, he would reject it. Secondly, the writing style of the fanfic could be off - putting. If it's too convoluted or hard to understand, Ash (as a character in this context) would not be interested. Thirdly, if the fanfic focuses too much on a romantic aspect between Ash and Misty in a way that Ash doesn't feel comfortable with, given his more friendship - and - adventure - oriented personality in the official story, he would reject it.
One reason could be that the fanfic has a strange or unappealing plot. For example, if it makes Ash do something completely out of his character, like being mean to Misty for no good reason.
One possible reason is a difference in goals. Ash might be focused on one type of Pokémon journey, like competing in a particular league. Misty, on the other hand, could have a different long - term goal, like protecting a specific water - type Pokémon habitat. If their goals start to conflict, it could lead to a situation where Misty seems to betray Ash to further her own aims.
It could mean that the character named Ash is rejecting a fan - created fictional work related to Misty. Maybe Ash's actions or personality in the fanfic don't align with how he is typically perceived, so the rejection occurs.
One possible reason could be that Hermione has a different romantic vision. In the original series, she might see Harry more as a friend. In the fanfic, her character could be written as being focused on her own personal growth and goals, which don't align with a romantic relationship with Harry.
One possible reason could be their different goals. Ash might be too focused on becoming a Pokémon Master and traveling constantly, while Misty has her own dreams related to the Cerulean Gym that she can't abandon. Their paths just start to diverge over time.
Perhaps in the fanfic, Hinata has fallen in love with someone else. It could be a new character introduced in the fanfic's universe or someone she has come to know better over time, leading her to reject Naruto.
One possible reason could be Naruto's pent - up anger towards Minato for leaving him as an orphan. He might feel that Minato sacrificed himself without fully considering the consequences for Naruto.
Another reason might be related to their different goals. Ash is mainly focused on becoming a Pokémon Master, while Misty might have her own goals that sometimes conflict with Ash's journey. This could lead to friction between them and eventually make Ash develop negative feelings towards her.
One key moment is when Ash saves Misty from a dangerous Pokémon. It shows his protectiveness towards her. Another is when Misty decides to stay with Ash instead of going back home. It indicates her commitment to their journey together. Also, the times when they share a laugh over a silly Pokémon's antics are important. These moments show the closeness between them.
One possible reason could be that Sasuke is too focused on his revenge. His single - minded pursuit of power and vengeance against Itachi leaves little room for romantic feelings. He might see a relationship with Sakura as a distraction from his goals.
One possible reason could be that Naruto has a different love interest in his heart, like Hinata. In the original story, his relationship with Sakura was more of a friendship - like bond. Another reason might be for the sake of creating an unexpected plot twist in the fanfiction. Maybe the writer wants to explore different emotional and relationship dynamics that don't follow the typical Naruto - Sakura pairing.
