When Hitler took power, he did not expect to die via suicide in a bunker while Germany was ravaged by the Allies. However, he had to have known he would die eventually. What was his plan for his successor? Did he assume he would have children to pass his title of Fuhrer onto, or would he appoint someone?

Related- was there any belief in Nazi Germany that Hitler had any kind of supernatural powers? i.e. that he would live forever (or a very long time), unnatural health, etc?
