You can only tell the same story so many times before it gets boring, even if that story is about an orphaned billionaire/last alien of its kind/radioactive arachnid enthusiast. That’s when comic writers turn to alternate universes to get creative and – frankly – quite weird.
We’re taking a stand here: Hitler was a bad guy. But he’s also the closest thing the world has ever had to a supervillain. His powers weren’t great (kind of a Lex Luthor thing) but damn if he didn’t have an iconic look that we recognize even to this day.
