Captain America / Iron Man #4

Something has gone very wrong between Marvel's most storied allies — the cover by Alex Ross depicts a hybrid Captain America/Iron Man figure at the center of the action, with Iron Man looming aggressively overhead and a helmetless Captain America tumbling helplessly below, his shield spinning away in the background. The painted composition crackles with tension, Ross rendering each figure in rich metallic detail that makes the collision of these two titans feel genuinely unsettling. Derek Landy, Angel Unzueta, and Rachelle Rosenberg bring this partnership-turned-powder-keg to issue four, and the cover alone makes a compelling case for picking it up.
