I'm not sure if there is such a specific fanfiction. There are a vast number of fanfictions out there, but this particular concept might be quite rare or not in line with the general tone of the 'One Piece' series. Fanfiction often explores different relationships and scenarios, but this one seems rather out - of - the - ordinary considering the nature of the characters in the original work.
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.
In Pulp Fiction, the person who gets shot in the car could be any of the numerous characters involved in the complex web of events. It might be a result of a sudden turn of events or a long-standing feud. Without a specific memory of that scene, it's difficult to give a definite answer.
One possible plot development could be that his friends and family rally around him. They might search desperately for the person who shot him. For example, if it was a case of mistaken identity, they could start to dig into Sam's recent activities to find any leads. Maybe they discover that Sam was unknowingly involved in something dangerous, like being in the wrong place at the wrong time during a criminal deal. This could lead to a whole new sub - plot where they try to figure out who the real target was.
One possible plot could be that Bakugou is in the middle of a battle with villains. He's being his usual brash self, charging ahead. Suddenly, a sniper from the villains' side takes aim and shoots him. His friends then have to rush to his aid and figure out how to get him medical help while still fending off the villains.
Well, in fanfiction when Naruto gets shot, the story could take a really dark turn. His injury might incapacitate him for a while, leaving Konoha vulnerable. This could force his friends to step up and take on his responsibilities. Maybe Hinata would be by his side constantly, using her Byakugan to monitor his condition. And his sensei, Kakashi, might have to come up with a new strategy to deal with the situation while Naruto recovers.
The immediate consequence is, of course, the physical harm. The child may suffer from severe pain, and there could be life - threatening injuries. For example, if a bullet hits a vital organ like the heart or lungs, it can be fatal.
In a '90210 Annie Gets Shot' fanfiction, the plot could involve Annie's friends and family rallying around her. Maybe they try to find out who shot her and why. It could also show her struggle to recover in the hospital, both physically and mentally.
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.
