Enforcers, also known as Attack Dogs or Personal (Body)Guards are a type of Henchmen designed to enforce higher Villains by any means necessary. They tend to be the Villain's Right-Hand or Left-Hand but may also be Hired Muscle. Also, Enforcers are almost completely loyal to their Masters and/or Mistresses at all times and would even rarely, if ever act on their own without guidance. This term is also used to describe hockey players who often fight while playing on the ice in a violent and aggressive manner. They can also overlap with Mercenaries and Assassins since they all generally function in similar capacities.

Even though most Enforcers are merely doing what their Bosses or Leaders tell them to do and therefore not always bad by their own choices, some can actually be aware of what they are doing to the point of being Pure Evil, notably if they are more or just as sadistic than those working above them and perform horrible acts they did not even get as orders (e.g. Roger committed murder and torture without Jack Merridew telling him, Peter Creedy betrayed Adam Sutler to take over his role and finish their plans by himself, Grimmel the Grisly already did heinous acts before the Warlords hired him and even betrayed them when their target was captured).
