Dieter Kotlar was born after the end of the World War I in Germany, when food was scarce and his mother had better things to do than tending to her child. This forced Kotlar to grow up faster, dealing in the black markets in order to substain himself and disposing himself as a bodyguard against the criminals that tried to plunder. When the NSDAP arose, Kotlar inmediately joined and turned into one of the most passionate orators of the party, soliciting for votes and beating those down who would oppose them. His passion affected a local Brujah, Isabell Corelli, into giving him the Embrace.
When World War II began, Kotlar followed the Wehrmacht into Poland, slaughtering many he deemed unworthy to live. When Germany lost the war, he returned to Berlin, embittered and determined to preserve the Third Reich. This lead to his support to Gustav Breidenstein, who in turn granted him the rank of Primogen, and the founding of the Final Reich, in order to retain the beliefs of Hitler and his fellows. Dieter doesn't like his fellow primogen Henry Jekyll, and is adamant in his hatred against foreign kindred and kine alike.
