Regulators (Fallout)

Lead by the sadistic Caleb, the Regulators are a vicious gang that serves as the "police force" of Adytum in Southern California. Nominally under the authority of Adytum's mayor, Jon Zimmerman, they in fact manipulate Zimmerman and control Adytum's affairs, ruling harshly, expropriating a good part of Adytum's industrial wealth for themselves, and enforcing forced labor on Adytum's citizens. To legitimate their authority, they have claimed that the Blades, a survivalist group to the north, are a threat, and frame them for crimes such as the murder of Jon Zimmerman's son.

Appearances
Caleb's Regulators appear only in Fallout. They are not related in any way to the Capital Wasteland Regulators from Fallout 3.
