The mid-1980's was a time of change for comics. Watchmen came out, Dark Knight Returns was published... well, it's been talked and written about a lot.
Perhaps most shocking however, is the scene from Batman Special #1. Batman knocks a woman unconscious, then is suddenly not wearing pants. His thoughts makes it even more disturbing.
(Yes, I know comics were color separated by hand back then, and his legs probably just got overlooked on the cyan plate. Why you gotta ruin my fun?)
