There are no exact details of his assumed roles in the said films, but it has been said that the roles will not help in his character development.

On the other hand, it is also possible Iron Man's rumored roles in Marvel's films can set-up for a bigger role for the Avenger. Some rumors consider the probability of using such cameo roles as hints at what fans can expect in "Iron Man 4."

While Downey Jr. once teased a release of a sequel, Marvel has yet to confirm announce its confirmation, as per Venture Capital Post.

Some fans remain hopeful for an "Iron Man 4," since Robert Downey Jr. reportedly tried to re-direct interview queries on a fourth "Iron Man" movie to the recently released "Avengers: Age of Ultron."

As there is no confirmation on "Iron Man 4," fans just have to wait for the Avenger's battle with Captain America concerning the superhero registration act in "Captain America: Civil War," in which Iron Man is rumored to be joined by War Machine, Vision, Ant-Man, and Spider-Man.

"Civil War" will star Downey Jr., Chris Evans, Scarlett Johansson, Jeremy Renner, Sebastian Stan, Elizabeth Olsen, Anthony Mackie, Chadwick Boseman, and Daniel Bruhl. "Spider-Man," who has no actor at this point, is also set to debut in the film.

Joe Russo and Anthony Russo are set to pilot the film, along with Kevin eige, Alan Fine, Trinh Tran, Patricia Whitcher, Lars Winther, and Mitchell Bell as their co-producers.

Christopher Markus and Stephen McFreely are on-board to pen the screenplay.

"Captain America: Civil War" is slated to premiere in theaters on May 6, 2016.
