Hate-Monger



Hate-Monger is a supervillain from Marvel comics who is actually a clone of Adolf Hitler, created by Arnim Zola, however over time this clone would develop into a unique villain in his own right and was originally a masked criminal devoted to spreading hatred (hence his name) - however after being reborn by the power of the Cosmic Cubes the Hate-Monger became a living embodiment of hate, made of pure energy and capable of installing hatred in others without the aid of his "H-Rays" (which stood for "Hate-Rays").

Other villains have also taken the name of Hate-Monger such as the Man-Beast, one of Psycho-Man's androids and an energy-vampire that changed his name to Animus.

Another interesting fact is that Hate-Monger's original uniform was very similar in design to the uniform worn by KKK - which was likely intentional.

Trivia
He is in league with HYDRA.
