He’ll Officially Break The Avengers Up

With Tony Stark and his allies willing to comply with the Sokovia Accords in the Civil War movie, Captain America and his team will be considered renegades. It will be Stark’s team who will officially be considered to be the Avengers and, therefore, it will be Stark who is considered to be the Avengers’ leader (remember, it was Cap who was officially in charge of the team previously).

However, after the previous events in New York, Sokovia and indeed the battle that will take place in Captain America: Civil War, Stark will come to the decision that the Avengers are doing more harm than good, and he will officially disband them. This will set the stage for them to reform in glorious fashion when Thanos threatens the entire universe in the Avengers: Infinity War movies in 2018 and 2019 respectively.
