Arn Anderson was the muscle of arguably the greatest wrestling faction of all time, The Four Horseman. Double A didn't get named The Enforcer for nothing. Ric Flair was the charismatic playboy, Tully Blanchard was the ladies man, and then the other member of the Horseman would change over the years. Regardless of who was brought into the group, Arn Anderson was always The Enforcer (bar the brief angle where he asked Curt Hennig to take on the title before Hennig would end up joining the nWo). Arn's role in The Four Horseman was one where when he spoke you listened, and he would always be ready for a fight. Other competitors could maybe get away with talking smack with some of his running buddies, but Double A wouldn't play things that way. He was there to get his hands dirty, often doing the messy stuff in order to keep the World Title around the waist of The Nature Boy. Simply put, when it comes down to it, The Enforcer itself it just a badass sounding name that fit Arn Anderson like a glove, making him the biggest badass of arguably the greatest faction that the wrestling business has ever seen.
