Ruby would be super embarrassed and excited at the same time. Jaune is her friend and the idea of their relationship being explored in fanfiction would make her heart race. Weiss would be analyzing it, looking for any inaccuracies in the way the characters are presented. Blake would probably be quietly reading it and enjoying the different perspective on the characters. Yang would be laughing and joking about it, especially towards Ruby.
I think Hamilton would be rather curious. Fanfiction can offer different perspectives on his life that he might not have considered. He would probably be most interested in those that explored his intellectual side, his writing, and his ideas for the new nation. He might be a bit taken aback by some of the more fictionalized elements that deviated too much from the historical facts, but at the same time, he might recognize the creativity behind them. He could also be interested in how the fanfiction was received by the public, as he was always aware of his public image during his life.
Black Widow/Natasha Romanoff would be very observant of the fanfiction. She'd look for how fans perceive her character, especially in terms of her relationships with other characters. If she finds any that she thinks are particularly well - written in terms of her character development, she might be secretly impressed. But if there are any that objectify her in a negative way, she'd be a bit annoyed.
Weiss would be more reserved. She'd approach it with a bit of caution, wondering if it was a well - written piece. However, if the fanfiction showed some good character development for Jaune related to his Tahm Kench fandom, she might start to warm up to it. For example, if it made Jaune more complex and interesting, she'd give it more credit.
They would have diverse responses. Tony would likely chuckle and think it's a cool take on their world. He might even get some inspiration for new tech from the fanfic's ideas. Steve would be more cautious, but he'd still appreciate the fans' love for the characters. He might see it as a way to keep the spirit of the Avengers alive in a different form.
They'd probably be intrigued. It's like seeing their characters through different lenses.
Well, Ruby might be really excited. Since Lancaster involves her and Jaune, she'd probably be all blushy and a bit flustered at first. Weiss might be a bit critical, analyzing the writing style and how the relationship is portrayed. Blake would likely be more laid - back about it, seeing it as an interesting take on the characters' relationship. Yang would probably be teasing Ruby about it non - stop.
When the Avengers read Peter Parker fanfiction for the first time, it's a mixed bag. Natasha would be observant, looking for how the writers depict Peter's character growth. Is it in line with what she knows of him? Thor would find it novel. He'd be like a child with a new toy, enjoying the different takes on Peter. Bruce might be a bit hesitant, not sure if he should be taking it seriously or not. But overall, they'd all be somewhat intrigued by this new form of storytelling about their young friend.
If it's a romantic fanfiction about him and Annabeth, he might blush a bit. After all, it's about his relationship. But he'd also be happy that people see their love as something worth writing about. If it's an action - packed fanfiction that has him on a new adventure, he'd be excited. He loves adventures, and seeing new ideas for his heroic deeds would be appealing to him.
For Ruby, the Naruto fanfiction would open up a whole new world of adventure. She'd be completely immersed in it, sharing her favorite parts with her team. Yang would have a blast reading it, especially when it comes to the powerful and flashy ninja techniques. She'd probably try to imitate some of them in a playful way. Weiss would analyze it from a literary perspective, critiquing the use of language and the pacing of the story. Blake would find the stories of the Naruto characters' growth and struggles to be very relatable, and would think about how similar themes play out in RWBY.
Well, if it's a comical Spider - Man fanfiction, Clint would be the first to laugh out loud. He has a good sense of humor and would enjoy the light - hearted take on Spider - Man. When it comes to dark and gritty fanfiction, Steve might be a bit concerned. He believes in the positive image of heroes, and such fanfiction could go against his ideals. Tony, however, might see it as an interesting exploration of the character's potential in different situations.
