If the Avengers read Naruto fanfiction, different members would have different reactions. Bruce Banner might study the way the characters control their inner power, like how Naruto controls the Nine - Tails' chakra. Steve Rogers might be more focused on the moral lessons in the stories. He would look for similarities and differences between the values in the Naruto world and their own. Natasha Romanoff could appreciate the complex relationships between the characters, just like she values her relationships within the Avengers. And Clint Barton would probably enjoy the action - packed parts, imagining how he could use some of the ninja skills in his own battles.
In this fanfiction, some Avengers might be in shock. For example, Captain America could be deeply saddened, his belief in justice and protecting the world shaken. He might feel a sense of failure for not being able to prevent the Snap.
It gives fans a chance to explore different 'what - if' scenarios. By seeing the Avengers' reactions, fans can get a deeper understanding of the characters.
Tony Stark might use his quick wit and technology. He could immediately scan Peter to make sure there's no physical danger causing the hyperventilation. Then he'd probably crack a joke to try and calm Peter down, like 'Kid, you breathe any faster and you'll fly away like a human jetpack.'
Some characters would likely be entertained. For instance, Loki might enjoy seeing the various ways fans write him as a more complex anti - hero. He'd probably find the creativity in the fanfiction quite appealing.
It can also be frustrating at times. Some fanfictions lack the proper understanding of the movie's lore. They might introduce concepts that don't fit well with the established Marvel Cinematic Universe. But on the positive side, many fanfictions are a labor of love. Authors pour their passion for the movie into their writing, and that can really shine through, especially when they capture the essence of the characters as we know them from the movie.
Well, one reaction could be excitement. Fanfictions often explore different aspects of the characters and storylines that might not have been fully delved into in the movie. For example, they might focus on the relationships between the Avengers in more depth, like the budding romance between Black Widow and Hulk. It can be really interesting to see how different authors interpret the characters' emotions and motives.
Iron Man would be angry. He'd probably use his technology to try and track Percy down. He might also start to review all the security protocols to make sure no other traitors could do the same. Thor would be more of the 'let's fight him head - on' type, but the other Avengers would have to hold him back until they have a proper strategy.
The Avengers would initially be in shock when they find out Peter is sick. Clint Barton would be the one to keep a calm head and start organizing things. Wanda Maximoff would try to use her powers to ease Peter's pain if possible. Vision would use his vast knowledge to try and find a solution. They would all be very concerned and do everything they can to make Peter better, from getting the best medical help to providing a safe and comfortable environment for him to recover.
