Iron Cross comes from a work where Red Skull won WWII not Hitler, and once Skull died the control of Earth went to his Heir, Dr. Doom. Cross is a member of the Thunder Guard, the Elite policing force of this world. The Exalted One snatched him from his world, where he was he worlds leading technical genius, because he wanted his technical expertise for his one team. Iron Cross, much like his 616 counterpart, is a powerhouse on many levels. But unlike the 616 counterpart, this Stark arch enemy is Steve Rogers aka Captain America. Which is funny because the leader of this team is none other than..
Steve Rogers, The Red Skull. On his world, the Axis and Allies were reversed. Germany lead the Allied forces and America is the heart of the Axis. And once the war was over, which Rogers and his team won, he was out into frozen suspension until present day when resistance levels were at a all time high. He was unfrozen and lead the Siege and claimed the world as his. Thru his battles he came across a power source, the Cosmic Cube. With the cube he managed to cleanse his Earth, which gave him a vision. Why stop at this earth? He will cleanse them all. He went from universe to universe gathering the ultimate team of warriors and under his leadership, his vision of a cleanse universe is almost at hand. The Exalted One, he is nazi perfection personified and his vision will not be prevented. By anyone.
