African Kung Fu Nazis

You have been lied to! Adolf Hitler and Hideki Tojo never died...but they fled by submarine to Ghana Africa. The constipation theories were true! Now these two evil men are brain washing local Ghanaians into Ghan-Arians and exterminate local Kung Fu heroes. Will anybody be able to stop them? Or will Himmler and Tojo finally be able to conquer the world? I mean Hitler, of course.
With their African Kung Fu Nazis!
