During World War II, he was a sadistic SS officer of a concentration camp in which Herbert was imprisoned. According to Herbert, those who Franz chose to put those on his left side would be sent to labor camps, and those on his right side were executed. Franz forced Herbert to do recycling, which would leave his hands greasy and dirty. After trapping Chris and his father Peter, Franz and Herbert have a long drawn-out battle when Herbert offers that only one of them would leave alive. Franz dies after falling off the porch stairs, unable to grab Herbert's hand. He was voiced by John Viener.
