The first anime series I've seen was called "Fist of the North Star". I remember watching it around 1992. The series told the story of a man named Kenshiro who sweared to protect people from the wild gangs of bikers, bandits, and other deviants of society who prey on them in a type of post-apocalyptic environment. The story and animation weren't all that spectacular at the time. The one thing the series was known for though, was it's bloody and gory fighting scenes.
