Why Hulk is fighting Iron Man theory

This is the scene where the Hulk is fighting Iron Man. I think I know why. Bruce is out of control. Iron Man is trying to stop him. They might be sending the Hulk to a different planet, because look at this guy's eyes.

Behind the Hulk you'll see some Africans. This may have something to do with it.

  

This is Black Panther's sister. The Black Panther lives in Africa. In my next post I'm going to talk about why the Avengers are in Africa.
