Black Widow could be the first to form a friendship with Elsa. Black Widow is very perceptive, and she would quickly realize that Elsa is not a threat but a potential ally. She has a way of getting close to people and making them feel comfortable. She could help Elsa adjust to the new and strange world of the Avengers, and they could bond over their shared experiences of being different from the rest of the group. Elsa's powers would also be something that Black Widow could see as a valuable asset in their missions.
Harry Potter himself would be likely to interact with Elsa. Given his own experiences with unique powers and his role as a hero, he would be sympathetic to Elsa's situation. They could bond over their shared sense of responsibility and their ability to do things that others can't. Harry could also introduce Elsa to his friends and the world of Hogwarts.
Jack from 'Kickin' It' and Tori from 'Victorious' seem likely. Jack is adventurous and has a good sense of humor. Tori is also quite fun - loving and creative. They could bond over their shared love for trying new things and standing up for what they believe in.
Iron Man would be a likely candidate. Tony Stark is known for his sense of humor and ability to tolerate eccentric personalities. He might see Deadpool's skills and be interested in using him for certain missions, while also enjoying the banter.
It could also be Annabeth and Black Widow. Both are highly intelligent and strategic. Annabeth's knowledge of architecture and ancient languages might be useful to Black Widow in certain situations, like deciphering an ancient code related to a new threat. Black Widow, in turn, could teach Annabeth some self - defense and espionage skills. They would see the value in each other's abilities and form an alliance quickly.
Another possibility is that Tony Stark and Nami would be the first to start an alliance. Nami is always interested in valuable things, and Tony has a lot of high - tech gadgets. They could start a business - like relationship at first, with Nami being intrigued by Stark's technology and Stark being impressed by Nami's navigation skills and her ability to handle money. This could then lead to a full - fledged alliance between the two groups.
I think Hamilton and Captain America would be likely to form an alliance. They both have strong beliefs in justice and freedom. Captain America fought for his country in a different time, and Hamilton was a key figure in the American Revolution. They could understand each other's values and work together towards some common goals, whether it's about protecting the people or promoting certain ideals.
Probably Naruto and Iron Man. Iron Man is always interested in new technology and abilities. When he sees Naruto's unique ninja abilities, especially the jutsu like Rasengan which is like a concentrated energy attack, he would be intrigued. Naruto, on the other hand, would be interested in Iron Man's high - tech gadgets. So they would start an alliance based on mutual curiosity and the potential of combining their skills.
I think Captain America from the Avengers would be one of the first to consider an alliance. He's all about justice and protecting the world, and when he sees the SG1 team's efforts in exploring and protecting the galaxy, he would recognize their similar goals. Also, Daniel Jackson from SG1 is very open - minded and interested in different cultures and people, so he would be quick to see the potential in teaming up with the Avengers.
I think Harry Potter and Captain America would be likely to form an alliance. Harry is a natural leader who has faced great evil in his world, and Captain America is all about justice and doing what's right. They would respect each other's values and leadership skills. They could lead their respective teams, the Hogwarts students and the Avengers, in the fight against the common enemies like Voldemort and Thanos.
Batman and Iron Man are likely to form an alliance. They both rely on their intelligence and technology. They might see the value in working together against a common threat. Another possible alliance could be between Wonder Woman and Captain America. They both have strong moral compasses and a sense of honor, so they could team up easily.
