The Red Skull
Trained by Adolf Hitler, the Red Skull was a frightening and ruthless officer for Germany in World War II. Opposed time and time again by Captain America, the Skull would survive the end of WWII through suspended animation. Awoken in present day, the Skull immediately started working towards his goals of revenge on Captain America, world conquest and general mayhem.
Here the Red Skull is sporting a stylish military-style uniform he's wore occasionally. Definitely a step up from his generic green jumpsuit, this non-denominational outfit screams "fascist evil" without associating him with any other evil group, like Nazis or the Shriners.
