X-Men: Starjammers by Dave Cockrum
Swashbuckling space pirates! In 1977, the X-Men went cosmic, traveling to the far-flung Shi'ar Empire - where they encountered the Starjammers! Corsair, Hepzibah, Ch'od, Raza, Cr'reee and Sikorsky quickly became fixtures of the X-Men mythos, and this volume features every appearance drawn by their co-creator, the legendary Dave Cockrum! First, the Starjammers must help the X-Men prevent universal Armageddon - but what happens when Corsair realizes one of the X-Men is his son? Then, when the parasitic Brood attack and Shi'ar Empress Lilandra is kidnapped, the X-Men fight a war on two fronts: without and within! But will Carol Danvers join the Starjammers? And in their first solo story, the team embarks on an interstellar quest for a cosmic object of immeasurable power!
