While they are not managers in the traditional sense, enforcers — full-time wrestlers who accompany another wrestler to the ring — also serve both in and out of storylines to further the interests of a wrestler in their care. They are named after Arn Anderson's nickname, The Enforcer, whose career has been highlighted by his association with Ric Flair and various members of The Four Horsemen stable. Enforcers appear in storylines where wrestlers need to have their back watched by keeping outside interference from taking place in a match, to serve as outside interference themselves, or to further a storyline without actually recording a real match by defending their associates from ambushes outside the ring by other wrestlers. The Acolytes Protection Agency (APA) had a unique gimmick where instead of a long term association with one wrestler, tag team or stable, they would be hired by different wrestlers each week to act as their bodyguards or to prevent outside interference.
