Captain America, Vol. 6

Here comes this final part of 'Shock to the System'.
Cap and his team capture Gyrich through an informant who also tips them off to the next target, Roger Gocking, formerly known as 'The Porcupine'. While Cap makes it to Gocking just in time to save him from a hail of bullets, Diamondback awakens to reveal to Dum Dum Dugan the true identity of the new Scourge: Cap's friend and one-time ally, D-Man. Now Cap must grapple with the reality of the new Scourge's true identity!
