In some fanfictions, Ash gets angry. He might be angry at the world, at fate, for taking his mom away. This anger could manifest in different ways, like being more reckless in battles or snapping at his friends when they try to comfort him. But deep down, it's just his way of dealing with the overwhelming pain of losing his mother.
Ash would be extremely heartbroken. He might cry a lot and be in a state of shock at first. Then he would probably feel angry at the situation that led to Gary's death, whether it was a villain or just a dangerous accident. Ash would also feel a strong sense of responsibility, as if he has to carry on Gary's unfulfilled dreams.
There are also fans who might be a bit angry or disappointed. They see Ash as a symbol of hope and perseverance in the Pokémon world, and having him die in a fanfiction goes against what they expect from the character. However, they also understand that it's part of the creative freedom in fanfiction writing.
In some of these fanfictions, a heartbreaking scene could be when Ash discovers his mom's death. He might come home after a long journey, excited to see her, only to find the house in mourning. The silence and emptiness of the place would hit him hard.
Well, his death would likely cause great sadness among the Pokemon. They've formed strong bonds with Ash. Some might become withdrawn or less trusting of humans. The Pokemon he protected would probably feel a deep sense of loss and guilt, as if they should have been able to prevent it.
Ash might initially be confused. He's used to his mother's love, but this new level of possessiveness could stump him. He may not understand why she's suddenly so overbearing.
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.
Ash would probably be devastated. He would feel like his world has been turned upside down. At first, he might not believe it and think it's all a big mistake. As the reality sinks in, he could start to isolate himself from others, even from his Pokemon for a while. However, his strong will would eventually kick in. He would use this as motivation to become stronger, not just in his Pokemon battles but also in his ability to face challenges alone, without relying on his so - called friends.
His relationships with his Pokemon can also change. If he gains weight and becomes less mobile, some of his more energetic Pokemon might have to take on more protective roles. This could strengthen their bond as they work together in a new way. Also, with his friends, he might become more reliant on them at first, but then grow stronger mentally as he overcomes the challenges related to his weight gain.
Ash would probably be very shocked and hurt. Pokemon are like his family, and for Misty to steal one would go against everything he stands for.
Ash might be heartbroken at first. He'd feel a deep sense of loneliness and confusion.
