Heroes who work as the servants of villains. Due to the loyalty they have to their masters, it is often possible or likely that they have no idea that their masters are evil. Sometimes they might be possessed or brainwashed by the villain. Sometimes they might be terrified of the villain knowing they will suffer consequences if they do not serve the villain.

Not to be confused with apprentices of a villain.

Good examples of heroes who served villains: Dominic Toretto, Finn, Ilsa Faust, Nick Morton, Other Wybie and Karai (TMNT cartoon series only).
