Maybe Captain America. Captain America values honor and loyalty, and Rhodey with his military background would share those values. They could bond over their sense of duty. Rhodey might look up to Captain America as a symbol of leadership, and Captain America would respect Rhodey's skills and experience. So Captain America could be his closest ally in the story.
Well, it could be that Rhodey brings some new technology from the military side to the Avengers. He could introduce some advanced weaponry or strategic plans. And perhaps there will be some humorous moments as he tries to fit in with the more 'out - there' Avengers like Thor or Hulk. He might have a hard time understanding Thor's Asgardian ways at first but then they end up becoming good friends.
In the 'Avengers meet Rhodey' fanfiction, it could start with Rhodey being called in to help with a situation that the Avengers are already involved in. They might initially be a bit skeptical of each other, but as they work together, they start to respect and rely on one another. Rhodey could bring in his strategic thinking from his military background, which could give the Avengers a new perspective on how to approach their battles. There could also be a sub - plot where Rhodey has to prove himself to some of the more powerful Avengers members, like Thor or Hulk, and through his courage and skills, he earns their respect.
One possible reason could be a misunderstanding during a mission. Maybe Rhodey made a decision that put Tony in danger without realizing it at first, and later realized his mistake. For example, if Rhodey called for backup in a situation where it attracted more enemies towards Tony. Another reason might be something related to their personal relationship outside of the hero stuff. Perhaps Rhodey said something unkind about Tony's new technology, not knowing how much effort Tony had put into it.
Obviously, Rhodey and the Avengers members like Iron Man, Captain America, Thor, Hulk, etc. would be the main characters.
I think it could be Captain America. He is known for his ability to see the good in people and his leadership. He would likely welcome Daisy and help her adapt to the Avengers' way of doing things.
The friendship between Tony and Rhodey in the fanfiction is a complex and multi - faceted one. It's based on mutual respect, as they both recognize each other's skills and intelligence. Rhodey respects Tony's genius in engineering and Tony respects Rhodey's military acumen. They also have a deep emotional connection, which is often tested by the challenges they face, but always manages to endure, making their friendship a central and heartwarming aspect of the fanfiction.
You can start by looking on popular fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfictions from various fandoms, and you're likely to find quite a few stories about Rhodey meeting Peter there.
One great story could be 'Unexpected Encounter' where Rhodey and Peter cross paths during a city - wide emergency. In this fanfiction, Rhodey is initially skeptical of Peter's abilities but soon realizes his potential.
One key moment could be when Rhodey first dons the War Machine suit. It shows their trust in each other as Tony has designed the suit for Rhodey, and Rhodey trusts Tony enough to use it in combat. This moment is a significant step in their friendship as it symbolizes their partnership in a more official way.
Tony might be initially skeptical. He's been through a lot and has trust issues sometimes. So, he might not immediately accept Rhodey's apology. For example, he could give Rhodey a cold look and say something like 'We'll see if you really mean it.'
