Enforcer

Enforcers are a variety of henchmen designed to enforce big bads or bigger bads by any means necessary. They can be the villain's Right-Hand or Left-Hand but they are before all hired muscle having a little more authority towards normal minions. Also, Enforcers are almost completely loyal to their leaders at all times and would even rarely, if ever act on their own without guidance. This term is also used to describe athletes who fight while playing 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 they are told to do and therefore, are not always bad by their own choices, some can actually be aware of what they are doing.
