Well, initially, many of the Avengers would be cautious. They're used to dealing with super - powered individuals. But as they got to know the Dark Knight, they'd start to see his value. Hawkeye might admire his precision and accuracy. The Scarlet Witch could be interested in his mental fortitude. And Vision might study his human - like determination in the face of great danger. Over time, they'd come to accept him as part of the team, although there would still be some cultural and ideological differences to work through.
Some Avengers might be excited. Captain America, for example, would probably welcome Nightwing for his sense of justice and fighting skills. Thor might be intrigued by this new addition from another world (in a sense, as Gotham is different from Asgard). However, Hulk might not care much as long as Nightwing doesn't get in his way during a fight. Overall, there would be a mix of curiosity and acceptance.
Well, initially, most of the Avengers would be a bit shocked. Here's this new, powerful being - a Sayian - wanting to join their team. Hawkeye would probably be a bit skeptical as he's used to relying on his own skills more than superpowers. But as time goes on, if Sayian proves their loyalty and helps in battles, the Avengers would gradually accept them. Vision, with his understanding of different beings, might be one of the first to try and bond with Sayian, seeing the potential in their combined powers for the greater good of the universe.
Some Avengers might be initially skeptical. Thor, for example, might not understand the power of a 'spider - boy' at first. But others like Captain America would probably see his potential and welcome him. Black Widow might be intrigued by his skills and try to train him further in espionage - related aspects.
Some Avengers might be suspicious. For instance, Captain America, who values order and loyalty, might be cautious about Moon Knight's erratic behavior. Iron Man, on the other hand, could be intrigued by Moon Knight's technology, especially if it has any connection to his lunar - based powers. Thor might see him as an interesting mortal with a connection to a different kind of divinity compared to his Asgardian gods.
Some Avengers might be skeptical at first. Captain America, for example, would probably want to make sure she's trustworthy. Thor might be more open - minded, seeing her as a potential ally with great strength. Hulk might not care much as long as she doesn't bother him.
The Avengers' reactions would be diverse. Natasha Romanoff would likely assess Harry's skills and how he could fit into the team. Bruce Banner might be intrigued by the scientific aspect of magic. Clint Barton would be observing to see how Harry operates in combat. Overall, they'd be a bit skeptical at first but as they see what Harry can do, they'd welcome him. For example, when Harry first uses magic to save one of them from a dangerous situation, their doubts would start to fade.
Some members might be skeptical at first. For instance, Kakuzu would be worried about how her presence could affect their money - making operations. But others like Itachi might see her as an opportunity to change the Akatsuki from within. He might try to guide her and use her positive energy to sway the group towards a more noble path.
Some of the SG1 characters might be initially skeptical. Daniel, being an archaeologist, would be very curious about Harry's magic. Jack might be a bit more cautious, but once he sees what Harry can do, he'd probably be more accepting. Teal'c would likely respect Harry's skills. Sam would be interested in how magic works and might even try to find a scientific explanation for it.
When it comes to the Justice League's reaction to The Dark Knight fanfiction, it's a diverse range. Batman, who is all about control and secrecy, may not like the liberties taken in the fanfiction. He could even feel that it undermines his real - life efforts. Superman, being the more optimistic of the group, could view it as a celebration of their superhero world. He might enjoy seeing how fans expand on the Dark Knight's story. Wonder Woman, coming from an ancient and different culture, would be fascinated by the modern human's creativity in the fanfiction. The Flash would be entertained by the fast - paced and often over - the - top nature of the fan - made stories.
