Well, in a lot of fanfiction, the Avengers watching Natasha's death is a very emotional moment. Clint, who was so close to her, might be inconsolable. He may vow revenge on those who put her in that situation. The newer members of the team, like Peter Parker if he's in the story, might be in awe of the sacrifice she made and look at the older Avengers with new respect, while also feeling the heavy loss of someone they had just started to know.
He could also become more defiant. Instead of trying to win back their favor, he might double - down on his actions and beliefs. For instance, if they hate him for his use of a particular technology, he might continue to develop it just to prove them wrong.
In some fanfictions, the Avengers could be watching her death through a magical or technological device that replays the event. They might then be driven to find a way to bring her back, with Tony Stark using his intelligence to search for a solution while Steve Rogers is more focused on the emotional aspect of their loss.
In fanfiction, Peter Parker might be portrayed as extremely opposed to drugs. Given his sense of responsibility, he could see drugs as a major threat to the safety and well - being of the people he's protecting. So, his reaction would be to take immediate action against any drug - related activities.
Well, typically, the Avengers' reactions are a mix of shock, guilt, and sadness. For instance, Black Widow might analyze the situation coldly at first, trying to figure out if it was a trick or not. But as she realizes it's real, she feels a sense of pity. Hulk might be confused and angry, not fully understanding the implications of Loki's death. And Hawkeye, who has had his own run - ins with Loki, could be conflicted between relief and remorse.
Well, Ruby would probably be the most excited. She loves all things combat - related. She'd be really into seeing how different characters from different universes are pitted against each other in the fanfic. Weiss might be a bit more critical, analyzing the strategies and the logic behind the battles. Blake would be intrigued by the different character dynamics and stories, while Yang would be cheering on the more intense and action - packed parts.
In many of these fanfictions, Natasha's character is explored through her vulnerability when she's sick. For example, in some stories, we see her usual tough exterior crack, revealing her fear and dependence on her team mates, which is a side of her we don't often see in the movies.
Ruby would be the first to jump into reading or listening to the Avengers fanfiction. She'd be all wide - eyed and eager, enjoying every bit of it. Weiss would probably roll her eyes at first but then get drawn in, especially if there was some complex plot or character development. Blake would be quiet as she absorbed it all, thinking about how it compares to the books she's read. Yang would be like, 'This is so cool!' or 'This is just plain bad' depending on what she was reading. They all would bring their own unique perspectives from their own experiences in Remnant to their view of the Avengers fanfiction.
Natasha's own journey might be explored. She could start working with a new group or go on a personal quest for redemption. Maybe she teams up with some old acquaintances from her past in the Red Room to take down a common enemy.
It could become more tense. If they see different versions of themselves or different outcomes for their relationships, it'll cause stress. For instance, if Vision sees a future where he and Wanda are separated, it'll be tough on their relationship in the present.
One possible fanfiction could be about Natasha's sister joining the Avengers. Maybe she has some unique powers like the ability to control minds on a small scale. She could start as a bit of an outcast, but as the story progresses, she earns the respect of the team through her courage in battles.
