Hermann is voiced by Hugh Davidson.
Very little is known about Hermann's past. Due to his age, and the release date of the episode, it can be assumed Hermann was born during the early twentieth century in Germany. He was a member of the nazi regime and, as revealed by picture found in his cabin, personally met the nazi füher, Adolf Hitler. Hermann survived the end of world war two and immigrated to the United States, where he had his two children: Alex and Elsa. However, they were unaware of his origins as a nazi.
