G.I. Joe, Volume 5: The Return of Serpentor — Tim Seeley

Since the day Cobra Commander reorganized his forces, prompting the G.I. Joe team back into action, he's met resistance within his own ranks. All the while, though, a third party was lurking in the shadows, waiting for the right moment to strike: Serpentor, the ex-Cobra emperor genetically engineered from the world's greatest, most ruthless conquerors, and an enemy to both G.I. Joe and Cobra. He's formed his own army from Cobra forces left behind by the Commander years ago - the Coil.Now Serpentor returns in an epic battle that spans from the days before G.I. Joe's reinstatement to their biggest melee to date. And in the end, Cobra Commander and Serpentor battle to determine who is the most ruthless leader of Cobra.
