One possible reason could be that Pikachu is separated from Ash. In many fanfictions, their bond is so strong that being apart would be extremely distressing for Pikachu, leading it to cry.
In some fanfictions, Pikachu might be bullied by other Pokémon. Since it is often depicted as a kind - hearted and friendly Pokémon, being bullied would be very upsetting. This could make Pikachu feel sad and start crying. It might be excluded by a group of Pokémon because it's different in some ways, like having a special power that others envy or fear.
Maybe Pikachu gets lost in a dangerous and unfamiliar place. It's a small and vulnerable Pokémon in such a situation. It could be scared and cry out of fear. For example, if it accidentally wanders into a cave full of menacing Pokémon, it would be terrified and start crying.
Using Pikachu's unique electric abilities in the description of its crying can be effective too. For instance, the tears could be described as having a slight electric charge, sparking a bit as they roll down its cheeks. This ties in with Pikachu's nature as an Electric - type Pokémon and makes the crying scene more unique and memorable.
One common reason could be jealousy among other Pokemon. Some Pokemon might be jealous of Pikachu's closeness to Ash and its popularity. So, they might plot against it and end up killing it. Another reason could be a misunderstanding. For instance, a wild Pokemon might misinterpret Pikachu's actions as a threat and attack it fatally.
One popular type of Pokemon Ash and Pikachu fanfiction might be adventure - based. For example, Ash and Pikachu could embark on a journey to a new and mysterious region filled with undiscovered Pokemon species. They might face challenges like difficult terrains and powerful, previously - unseen Pokemon. In this fanfiction, Pikachu's electric powers could be enhanced in some unique way, and Ash would have to strategize differently to overcome the obstacles.
Maybe Pikachu is feeling neglected by its trainer. If the trainer has been paying more attention to other Pokemon or is too busy with something else, Pikachu might decide to run away to get some attention.
In this kind of fanfiction, Ash might find it really hard at first. He's used to being a human trainer, and suddenly becoming a Pikachu would be a shock. He'd have to learn how to control Pikachu's electric powers which he only used to command before.
Perhaps Pikachu is lured away by something more appealing. There could be a rare and powerful Pokémon or a special kind of food that distracts Pikachu from protecting Ash. Also, Pikachu might have received some false information. For example, it might have been tricked into thinking that Ash has a better chance of escaping the Spearow without it. In the heat of the moment, Pikachu makes a hasty decision based on this wrong information.
Ash would be completely devastated. Pikachu has been his closest companion since the start of his journey. He would probably go into a state of shock at first, unable to believe that Pikachu was gone.
No. Pokemon, especially Pikachu which is a beloved character, should not be the subject of abuse in fanfiction. It goes against the positive and friendly nature of the Pokemon franchise.
One way to develop her character is through her relationships. Besides Ash, she could have a special friendship with other Pokémon in Ash's team. Maybe she is like a big sister to the younger Pokémon, teaching them things and protecting them. This would show her nurturing side and develop her character further.
In a far - off land, Pikachu fell in love with a Gardevoir. Pikachu was enchanted by Gardevoir's grace and psychic powers. Gardevoir was initially hesitant because they were so different. But Pikachu's persistent kindness won her over. He would sit and listen to her talk about the mysteries of the psychic realm. As they got closer, Pikachu's love gave Gardevoir the courage to embrace their relationship, and they became an unlikely but loving pair.
