Captain America…criminal?! The Secret Empire was rarely more secretive or empirical than in this classic arc that sets Cap against a conspiracy out to frame and replace him in the American mind! And pay close attention to the man behind the curtain (or mask, as the case may be)! Nick Fury, Black Panther and Banshee join the action, and the X-Men guest-star (back before it was cool) as the Secret Empire’s shocking agenda is revealed! Corruption and cover-ups conclude with Cap shaken to his core. But will he turn his back on the Avengers, ditch the red, white and blue — and become a Nomad? Collecting CAPTAIN AMERICA (1968) #169-176.
