Hitler as a young boy was told the prophecy of the great bearded one that would eventually lead to the 1000 reign of the Holy Roman Empire (currently Germany). So on the eve of Chuck Norris's birth, he had his transferred body into a mechanized exoskeleton in order to prevent his assassination. He held himself up in Castle Wolfenstein in order to prevent his demise. His plan only delayed the inevitable, and 5 years later was roundhouse kicked by the Great Bearded One. Destroying every Nazi in the process.
