Dr. Eggman could be the antagonist. He's always trying to defeat Sonic, and shooting him could be part of one of his evil plans. Maybe he developed a new weapon specifically designed to take Sonic down.
One possible scenario could be that Sonic is shot by a robotic enemy while trying to protect his friends. He might then have to rely on his friends to get him to safety and find a way to heal his wound. Another could be that he's shot by a misfiring weapon of a friendly character, leading to a lot of guilt and a race to save Sonic's life.
Perhaps a mysterious stranger who has some unknown vendetta against the Heartland family. This person could have been lurking around the ranch for a while, waiting for the perfect opportunity to strike. Or it could be someone within the community who has a hidden agenda and sees Amy as an obstacle to their plans.
I'm not sure specifically as there could be various interpretations in such a fanfiction. Maybe Metal Sonic sets Sonic up in a way that makes Sonic look bad to the other characters, perhaps by faking some evidence or causing chaos and making it seem like Sonic's fault.
There were a few novels about the CEO getting shot. Among them," Enemies of a Rich and Powerful Family, Cold CEO's Duel " was a modern romance novel. It was about the female protagonist and the male protagonist meeting by chance. Their relationship gradually warmed up, but the female protagonist's choice eventually led to the male protagonist's misunderstanding. In addition," I and All Things Protect You " was also a recommended novel. The plot of the male protagonist blocking the poisonous arrow for the female protagonist appeared in it, and the entire story was very sweet. In addition," The Crown Prince Abandons His Concubine " and " My Beloved Concubine, I Don't Allow You to Escape " were also ancient romance novels. In them, the female lead blocked the sword for the male lead, but in the end, she didn't die. I hope these recommendations will meet your needs.
Positive Sonic fanfiction could be about Sonic mentoring the younger characters like Tails and teaching them important life lessons. Or it could be about Sonic and his friends having to solve a mystery in their world, like a strange disappearance of an important item or character. Fanfictions that show the characters growing and evolving in positive ways, such as Amy becoming more confident in her own abilities, are also excellent alternatives to inappropriate fanfiction themes.
In many 'Katniss gets shot' fanfictions, she might face a life - threatening situation. Her friends could rush to her aid. For example, Peeta might use his skills to protect her further while waiting for medical help. Maybe Gale tries to find the source of the shooter and avenge her.
Sonic would probably be very shocked at first. He trusts Amy, so her betrayal would be unexpected. He might initially try to talk to her to understand why she did it.
It could be Dr. Eggman. He's always been after Sonic and trying to defeat him. Experimenting on Sonic could be his new way to find Sonic's weaknesses or to gain his powers for himself.
