I admit the show's definitely a little dark for my taste, but I think Zim is one of the best-designed characters I've seen for a while. And I always did wonder what would happen if he ever found out his mission was a hoax. My best guess was something close to this, at least he'd be apprehended/imprisoned if he ever step foot back on his planet.
Not fair. He may be a super-villain in the works, but he's practically a kid.
