The woodland creatures that live in Thranduil's forest would sense that something is wrong. The birds might stop singing as much, and the deer would be more skittish. His elven subjects would come together. The younger elves would be inspired to train harder in case they need to defend the kingdom while Thranduil is injured. The older elves would be reminiscing about past battles and how Thranduil led them through tough times, and they would be determined to see him through this difficult period as well.
The dwarves, if they are part of the story's universe, might initially be skeptical but then realize the importance of Thranduil's leadership in maintaining the balance in Middle - earth. If there are any human allies, they would send their best healers or offer any resources they can. His enemies, on the other hand, might see this as an opportunity to strike, but they would also be cautious as they know Thranduil is still a formidable foe even when injured.
Some members of the superfamily might be immediately filled with rage and want to seek revenge on whoever hurt Peter.
Sasuke, on the other hand, might act like he doesn't care much on the surface, but deep down he would be a bit confused and might start to see Naruto in a new light. He's not very good at expressing emotions, so his reaction would be more subdued.
Iruka would be inconsolable. He was like a father figure to Naruto in the early days. His death on his birthday would bring back all the memories of Naruto's growth and how far he had come. The village as a whole would go into mourning. Naruto was the hero who saved them multiple times. There would be a sense of hopelessness among the villagers, and they would struggle to find a new source of inspiration without Naruto around.
Well, it depends on the character. A tough, battle - hardened character might be more intrigued than scared. They could see the SCP fanfiction as a new kind of threat or mystery to analyze. However, they might also be disgusted by some of the extreme and unethical elements within the SCP stories. Like a detective character, they would try to make sense of it all but might be put off by the overall dark nature.
Sasuke would be deeply affected. He and Naruto had a complex relationship, from being rivals to friends. He would likely feel a sense of guilt, as if he should have been there to protect Naruto. Sakura would be heartbroken. She had always cared for Naruto, and seeing him die in such a tragic way in front of his parents would make her feel helpless. His parents, on the other hand, would be in utter despair. His father might feel like he failed as a father again, not being able to protect his son this time either.
His friends from Team 7, like Kakashi, would feel responsible for Naruto's situation. Kakashi would likely use his resources to find a proper shelter for Naruto. Shikamaru and the others might come together to form a sort of support group for Naruto. They would pool their resources, like money and food, and also try to cheer him up by sharing stories and jokes.
Hermione, on the other hand, would likely have a more critical view. She'd analyze the fanfictions for their accuracy in terms of magic lore and Hogwarts traditions. If there were any inaccuracies, she'd be quite perturbed. However, she might also appreciate the creativity that goes into some of the well - written ones that add new dimensions to their magical world.
The characters' reactions would vary widely. Annabeth would likely be critical of any fanfiction that got the details of her character or her knowledge wrong. She's very intelligent and detail - oriented, so inaccuracies would bother her. On the other hand, if a fanfiction captured her essence well, she might secretly enjoy it. Leo would probably be excited to see all the creative ideas people had in fanfiction, especially if there were cool new inventions or adventures in them.
Some might laugh. They could find the humorous takes in the fanfiction really entertaining. Maybe there are some comical interpretations of their actions or dialogues that they themselves didn't expect.
Sakura might be initially shocked and a bit scared of Robocop's robotic appearance. But once she realizes he's on their side, she would be interested in his technology and might even try to learn from it to improve her medical ninjutsu tools. Naruto, on the other hand, would be super excited. He'd probably want to immediately be friends with Robocop and would be eager to see what kind of cool moves he can do. Kakashi would be more cautious, observing Robocop carefully to assess his capabilities and motives.
