In these types of fanfictions, Marinette's act of getting hurt protecting Chat can have multiple consequences. It could inspire other characters to be more heroic. It might also make the overall story darker and more complex. For instance, if Marinette is severely injured, the city may be in more danger as Ladybug is out of commission for a while. This then forces other characters to step up their game and fill in the gap. It can also lead to some really emotional and heart - wrenching scenes between Marinette and Chat, as they deal with the aftermath of her injury.
One popular 'Marinette gets hurt' fanfiction might be 'The Trials of Marinette' where she gets injured during a battle with a powerful akuma. It shows her vulnerability and the concern of her friends.
Another aspect to consider is that it could be a way to develop his character further. Through his injuries and the pain he endures, we can see his growth, his vulnerability, and how he copes with difficult situations. This can add depth to his character in the fanfic.
There would be a great deal of gratitude from Iris towards Shinra. She would likely feel guilty that he got hurt because of her. Shinra, on the other hand, might feel a sense of fulfillment in protecting her, despite the pain.
The theme of heroism is also present. Timmy becomes the hero in these stories, even if he gets hurt. His actions inspire Trixie to be braver herself. And there could be a theme of redemption, especially if in the normal story arc Trixie has been mean to Timmy, but now she has a chance to make it up to him as he's injured because of her.
Vivi would likely feel a great deal of guilt. She might blame herself for putting Luffy in harm's way. After all, he got hurt because of her. This guilt could drive her to be more proactive in helping him recover.
Annabeth would be very shaken up. After the initial shock, she would assess the situation calmly. If Percy is unconscious, she would try to find a way to wake him up. She might talk to him, recalling their memories together, hoping it would reach him on some level. And she would be very protective of him while he's injured, not allowing any further harm to come to him. She would also feel guilty, thinking that if she were stronger or more careful, Percy wouldn't have had to protect her and get hurt in the first place.
There could be fear as well. Seeing Naruto injured, Sakura might be afraid of losing him. This fear could drive her actions in the fanfiction, whether it's in finding a cure for his injuries or in taking revenge on those who hurt him. It would also add more depth to their relationship as she grapples with these complex emotions.
