Hawkeye could also form an alliance. He's used to working with a diverse team, and Deadpool's unpredictability might be an asset in some situations. Plus, Hawkeye could keep Deadpool in line to some extent with his no - nonsense attitude.
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.
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.
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.
It could be Orochimaru. His thirst for power and his willingness to experiment on others would put him at odds with both Naruto and Deadpool. Orochimaru might see Deadpool's regenerative abilities as something to study and Naruto as a threat to his plans. He could try to capture them and use their powers for his own dark purposes.
The Green Goblin could be a likely villain. He has a long history with Spiderman and his maniacal nature would put him at odds with both Spiderman and Deadpool. His glider and pumpkin bombs would be a real threat to them.
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.
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.
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.
Deadpool and Iron Man would be really interesting. Iron Man is all about high - tech and calculated moves, while Deadpool is wild and unpredictable. They could have some great banter, like Deadpool making fun of Iron Man's suits or Iron Man trying to get Deadpool to follow some sort of plan.
I think Deadpool and Thor would be an exciting pair in the fanfiction. Thor is a noble and powerful Asgardian, while Deadpool is this crazy, regenerating anti - hero. The contrast between their personalities would be huge. Deadpool would probably make fun of Thor's old - fashioned speech and Thor would be both confused and intrigued by Deadpool's strange behavior. And in battle, they could combine Thor's lightning powers with Deadpool's unorthodox combat moves.
