History
Doctor Groitzig was a Russian scientist who was forced by the Red Skull to create a Doomsday weapon during World War II. When American spies Richard and Mary Parker went on a mission to put an end to the Red Skull's plot, Groitzig secretly gave them the information they needed before they were killed in a plane crash. The Red Skull tried to have Groitzig terminated after getting what he needed, but he was saved by the Six American Warriors, and the Red Skull became trapped in a vortex.
For fifty years, Groitzig was presumed dead, but he was secretly hiding in his daughter Illyena's house. When the Red Skull was released from the vortex, he had Groitzig kidnapped, but he was saved and the Red Skull stopped yet again by the Six American Warriors.Notes
