Germans come in a wide variety of stereotypes. Brutal barbarians from the north, cold blooded Knights Templar, corrupt aristocrats, Those Wacky Nazis, and many more. But at the end of the day, there are only three German stereotypes: Scientists/Doctors, Soldiers and Engineers. And no matter of which variety a German character is, he will almost always be very good at what he's doing. Note that Germans never lose their nerves and know no remorse. They do their job, and they do it well. Emotions are not necessary. It's almost like a national badasstitute of some kind.
