Collects Uncanny X-Men Annual (2006) #3, Steve Rogers: Super-Soldier Annual #1 and Namor: The First Mutant Annual #1
*It should come as no surprise: Bad things happen to good people in the Negative Zone. When the X-Men try to build an extradimensional bridge to Limbo, an explosion sucks Cyclops, Hope, Dr. Nemesis and Namor the Sub-Mariner into the Negative Zone instead! Cast adrift in the strange dimension, the X-Men are besieged by giant monsters, insectoid soldiers, and the lord and master of the Negative Zone himself: Blastaar, the Living Bomb-Burst! As Namor goes mad from lack of water, and Dr. Nemesis pursues his own agenda, Blastaar captures Cyclops and Hope - broadcasting hostage demands back to Earth. Enter Steve Rogers, Super-Soldier - the original Captain America! *Source: marvel.com
