Ku Klux Klan (Marvel)

The Klu Klux Klan are an infamous hate-group from North America who have appeared in countless works of fiction, even the fantastical realms of Marvel comics - they are perhaps most infamous for being the main antagonists of the aptly named "Black Panther versus the KKK" - which would pit one of Marvel's first and most popular superheroes of color against one of the world's most notorious White Power groups.

Trivia

 * many of the X-Men's most prominent enemies such as Humanity First and the Purifiers are based on the KKK, strangely the KK have not made many appearances within that media (though perhaps this is due to the extreme controversy of the Klan, which limits the number of appearances the group make in Marvel as a whole).
