The MCU fan base is already starting to look past The Avengers: Age of Ultron to the next epic battle Captain America: Civil War.
MCU fan art is also taking a stand. In the Civil War between Captain American and Iron Man fan artists are positioning Steve Rogers to the left of the political dividing line and Tony Stark to the right of the line.
Don't put that much truth in that. The positioning is probably more of an artistic choice than a political one. The blue of Captain America's uniform is on the left side of the Color Wheel. Iron Man's red is on the right side. The blue and red of the Spiderman uniform puts Peter Parker, or whatever character iteration that plays Spidey, squarely in the middle. (Now you know the origin for the real blue state and red state used in political geographic maps.)
The one poster that radically inverts this color divide is Orlando Arocena's Civil War homage, filled with his trademark vector artwork. I especially like the semi-Ultron suggestion in the Iron Man body styling. Arocena is not afraid of being blunt about who he thinks the real villain of Civil War should be. Red is the oppressive color. The depiction of blue Captain America's skull crushing is exceedingly visceral and brutal.
Captain America: Civil War is scheduled to be released everywhere on May 6, 2016.
