The Avengers is coming up next year. the teams members need to interact, and show emotion to the other members. I am placing the members in pairs of 2. This is how I think the chemistry will be at the beginning of the movie:
Friendships:Black Widow and Hawkeye: they are both SHEILD agents. It is still unknown if they have met in the past, but they will most likely understand and consider each other. , Captain America and Iron Man: They will be competing for team leader, but it will be a friendly rivalry. They will become fast friends, with Tony teaching the future, and Steve,the past.
Rivals/Enemies: Everyone and Hulk: No one likes Hulk's bad attitude, and seemingly inability to take orders from anyone. Thor and Iron Man: Iron Man will not completely accept Thor's magic. Thor will not completely accept Tony's use of technology.
And this is what I think the chemistry will be at the end. The pairs above are included except for changes I make:
Friendships:Hulk and Everyone: They will accept Hulk for who he is, and so Hulk will start to listen to them in return. Everyone will understand each other and consider them. They will become a true team. However, Thor will remain weary of Stark's tech.
What do you think the chemistry will be? Did I miss anyone? Tell me in the comments!
