Adolf Hitler
From UnAnything Wiki
Adolf Hitler (now as Adolf Shitler) was the Big Bad in Der Fuehrer's Face, even though he did not appear in that movie in his corporeal form. He was a leader of Naziland, and he was probably something like a god-like supreme leader. He is also the Satan figure in Esoteric Hitlerism.
In real life, he was the guy who made Germany stop being the Weimar Republic and start being the Third Reich.
