Despite the development of the Modern Centurion by the humanoid Cylons, some of the original Centurions remained in operation aboard the Cylon Colony. Serving alongside their modern counterparts, these Centurions were instrumental during the Battle of the Colony, when remaining Colonial forces launched an all out offensive to retrieve the half-Cylon, half-Human child Hera.

 

Armed with advanced weaponry, these Centurions engaged in combat against rebel Cylon Centurions, dubbed "Red Stripes" by the crew of Galactica. The Centurions also acted as shock troops, boarding the Galactica at platoon strength. Ultimately, though, the Cylon boarding parties were repelled and the remaining Centurions were presumably destroyed when the Colony itself was knocked into a black hole ("Daybreak, Part II").
