Well, it depends on the type of hurt. If it's a minor injury like a scratch from a wild Pokémon, Bonnie might be more worried about the Pokémon that hurt her rather than her own pain. She's that kind of character who is curious about Pokémon. But if it's a more serious injury, it could lead to a big adventure where they have to find a special cure or a rare Pokémon that can heal her.
The story could progress with the group having to slow down their journey. They might have to stay in a town longer than planned to let Bonnie recover. This gives them a chance to interact more with the local Pokémon and people, leading to new sub - plots.
I'm not sure of a specific one off - hand. But you could try searching on fanfiction - dedicated websites like FanFiction.net or Archive of Our Own. Just type in 'Pokemon X and Y Bonnie hurt' in their search bars, and you should be able to find some relevant stories.
A fanfiction might depict Ash getting hurt when he gets involved in a fight with a powerful trainer. The trainer could have a very aggressive Pokemon that doesn't follow the normal battle rules. This Pokemon might attack Ash directly instead of focusing on his Pokemon. Ash could be bitten or hit hard, causing him pain and injury. He might also be hurt when trying to rescue a trapped or endangered Pokemon in a collapsing building or a flooded area.
Ash would be very worried. He would immediately rush to Serena's side. He might stop whatever he was doing, like a Pokemon battle or exploring, and focus all his attention on her. He would probably ask if she's okay and check for any serious injuries.
In the fanfiction, Bonnie's Pokemon might develop new abilities or behaviors due to the mermaid influence. Her Sylveon could start to communicate with the mermaids in a unique way, perhaps using its ribbons to send messages. This would make Bonnie see her Pokemon in a new light, and their relationship would grow deeper as they all adapt to this new situation together.
There's a fanfiction called 'Bonnie and the Mysterious Eevee'. In this one, Bonnie stumbles upon an Eevee with unusual powers. It's a really heartwarming story as she tries to understand and help the Eevee. It shows Bonnie's kind heart and her determination to do what's right for Pokemon.
One possible fanfiction could be about Bonnie getting hurt during a Pokemon battle. Maybe she tries to protect her Pokemon and ends up getting injured herself. It could show her courage and the bond between her and her Pokemon.
Chica could also be a main character. She could be the one who tries to comfort Bonnie while he's sick. Maybe she brings him some virtual food or something to cheer him up. And Foxy might be another important character. He could be the one who goes on adventures to find a cure or a way to fix Bonnie. He's the more adventurous type, so it would make sense for him to be the one looking for solutions outside the normal areas in the pizzeria.
No. Fanfiction that involves rape is extremely inappropriate and unethical. It promotes violence and harm towards a character, which is not acceptable in a creative or moral context.
