Well, Natasha Romanoff would likely analyze the fanfic from a strategic point of view. She might be interested in how the characters in the Umbrella fanfic interact and what their motives are. Bruce Banner would probably be a bit hesitant to engage with it at first. He might be worried that it could be some kind of strange or inappropriate thing. But if it turns out to be a well - written and innocent fanfic, he might find himself getting into the story. Clint Barton would probably just shrug and say something like 'As long as it doesn't get in the way of our real work.'
Yes, there are many. You can find them on various fanfic platforms. Some focus on crossovers between the Avengers and the Umbrella Academy characters, creating unique and exciting storylines. For example, there might be a story where the Avengers and the Umbrella Academy team up to fight a common enemy. The different powers and personalities of the characters from both universes interacting can make for really engaging reading.
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.
Natasha Romanoff's calculating and perceptive personality means she would dissect the fanfic. She'd look for hidden meanings and motives within the story. Bruce Banner, being shy and introverted, would probably be more hesitant to share his thoughts on the fanfic. Clint Barton, who is laid - back, would probably just go with the flow and not overthink his reaction. For instance, if the fanfic had a character similar to one of the Avengers but with a different backstory, Natasha would be the first to notice and analyze how that changes the overall narrative, while Clint might just say 'Hey, it's different but cool.'
He might also get angry. Peter has a strong sense of justice. If he feels that the Avengers are being unfair, he could stand up to them. He'll use his quick wit and his powers to show that he's not going to be pushed around easily.
Some of them would be amused. Hawkeye might chuckle at the outlandish scenarios in the fanfic. Black Widow would be more reserved but still interested. She'd be quietly observing and thinking about the implications of the story. Captain America would try to find the moral of the story, if there is one, as he always does.
One interesting idea could be the Avengers' reactions to seeing alternate versions of themselves. It adds a new layer of self - discovery and character exploration. For example, they might see a version where they made different choices and learn from it.
