Savage Theron were Savage Locust or just regular Theron Guards that appeared after the Hollow was flooded and the Locust Horde began falling apart. They are nearly identical to the original Theron except for the color of their armor which is nearly bleached white garnished with red lights. They also used different weapons most of the time. For example, most Savage Therons use a Butcher Cleaver or Sawed-Off Shotgun rather than their iconic Torque Bow.
