The Chancellor and later dictator (Fürher) of Germany from 1934 to 1945, as well the leader of the infamous Nazi Party, and writer of Mein Kampf. Commonly known as the Führer, and near-universally despised all over the world, especially in Europe, for the racially-motivated detaining and killing millions of people. Generally held as the individual most responsible for starting World War II in most historical accounts. It's a common practice to feature him in almost any media, usually as a main villain, often with very impossible acts of evil or plans of world domination.
Notable feature: his moustache.
