Origin

Otto Kronsteig was one of Hitler’s most brilliant scientists, during which time he apparently developed a way to extend his life span. After the Nazi‘s defeat he fled Germany and sought refuge in Dr. Doom’s Latveria, where he helped Doom create a size-reduction ray.Â
Fearing that his assistant would attempt to betray him Doom tested the finished ray on Kronsteig. Shrinking into a microverse, Krosteig arrived at the planetoid Moto ruled by the reality-altering Shaper of Worlds who, tired of bringing the slug-like inhabitants’ dreams to life, fulfilled Kronsteig’s dream of a Nazi-invaded USA by tuning the Motons into human beings, creating a war-torn Manhattan and installing Kronsteig as Fuhrer on Wall Street.Â
