Other related modern theories involve Hitler having escaped to the Antarctic, where he joined with a subterranean dinosauroid master race, with whom he now travels inside UFOs underground, generally beneath the South Pole or throughout the center of the hollow earth, but sometimes to a Nazi moon base as well.

In 1905 Lanz von Liebenfels published a fundamental statement of doctrine titled Theozoologie oder die Kunde von den Sodoms-Äfflingen und dem Götter-Elektron (Theo-Zoology or the Lore of the Sodom-Apelings and the Electrons of the Gods). The author claims that “Aryan” peoples originate from interstellar deities who bred by electricity, while “lower” races were a result of inbreeding between apes and humans. Like much of Nazi mysticist propaganda, the book relies on a somewhat lurid sexual imagery, decrying the abuse of white women by ethnically inferior, but sexually active, men. Thus, von Liebenfels advocates mass castration of racially “apelike” or otherwise inferior males. This was in fact acted out during the Nazi era “purification”.
