Oooh... I guess the fact that it's a big slap to the face of status quo BS. Cause one of the problems with a lot of superhero media is that the villains can often have a legitimate point, but then they have to do something shit to make them awful. It turns into something that tries to defend or support the status quo. The Korps is a fun counter to it. The villains are the main characters, and they're "evil" in the sense that they're rebelling against said status quo. Plus, I'm a sucker for Hero to Villain and Villain to Hero storylines (though the latter doesn't really happen in Korps much).
