The Führer of the Fourth Reich is the unnamed leader of the Fourth Reich in the post-apocalyptic metro system. The Führer's background isn't widely known. Most of what is known is likely propaganda by the Nazis, attempting to promote a great past. It isn't fully understood when he came in power, or if he originally formed the Reich. We can only speculate. It is most likely that he was apart of a Neo-Nazi Russian group before the war.
