ANTÆUS
In a world populated by international ne'er-do-wells and fiends known exclusively by such colorful epithets as The Egyptologist, The Leper, The Doktor, The Dreadnaught, The Conquistador, The Croatian, and The Albino (actually, he's a good guy), what would you call a time traveler intent upon forestalling the rise of the Third Reich by helping the Central Powers - the German Empire, the Austro-Hungarian Empire, the Ottoman Empire, et al. - prevail in the Great War?

The sole halfway decent idea I have at present is The Futurist, but I'd like to devise some other options, something that seems more of a piece with the Edwardian era.
