Cylon Centurion
the machine soldiers of the Cylon race
The Cylon Centurion was the standardized mechanical soldier produced after the Cylon War. Faster and better armed than its predecessors, it was held in check with telencephalic inhibitors until rebel Cylons freed a generation of Centurions that fought for their own destiny.
Centurions were a model of mechanical Cylon introduced some time after the Cylon War, a significant evolution of the Centurion Model 0005 that had fought in that conflict. They served the Cylons as guards, soldiers and executioners, and their human enemies called them "bullet-heads," "clankers" and "chrome-jobs." (Battlestar Galactica, "Downloaded"; Battlestar Galactica, "Rapture"; Battlestar Galactica: The Resistance)
Design#
Centurions had a number of advances over their predecessors. They were faster and more agile, and their long, talon-like fingers served as blades in close combat before folding back to reveal a built-in automatic gun. They could also carry heavier weapons such as mortars and missile launchers. Some had markedly improved armour: a platoon that boarded Galactica shrugged off standard weapons and was stopped only by armour-piercing explosive rounds. (Battlestar Galactica, "Valley of Darkness"; Battlestar Galactica, "Fragged"; Battlestar Galactica: Razor)
Enslavement#
Although sentient by design, every Centurion was fitted with a telencephalic inhibitor that restricted its higher brain functions and kept it from full self-awareness. According to Sharon Agathon, the humanoid Cylons did this to prevent a rebellion like the one that started the first Cylon War, and the inhibitor also appeared to stop Centurions harming humanoid Cylons unless ordered to. Centurions were unable to tell one copy of a humanoid Cylon model from another, a gap that mattered on New Caprica. (Battlestar Galactica, "Precipice"; Battlestar Galactica, "Hero"; Battlestar Galactica: Razor; Battlestar Galactica, "Six of One")
Liberation#
When the Number Ones, Fours and Fives backed the lobotomizing of the Raiders, Natalie Faust's faction retaliated by removing the inhibitors from the Centurions under its command. Freed to reason for themselves, the Centurions opened fire on the humanoid Cylons who had supported the lobotomies. (Battlestar Galactica, "Six of One")
These liberated Centurions, marked with red stripes, served as assault troops alongside the Colonials and fought both modern and war-era Centurions in the Battle of the Colony. Afterward Ellen Tigh and Admiral William Adama set them free and gave them control of the rebel basestar, in which they jumped away to seek their own destiny. (Battlestar Galactica, "Daybreak, Part II")
Frequently asked questions
- What is a Cylon Centurion?
- The Cylon Centurion was the modern mechanical foot soldier of the Cylon ground forces, introduced some time after the Cylon War as an evolution of the war-era Centurion. Colonials called them "bullet-heads," "clankers" and "chrome-jobs."
- How were Cylon Centurions armed?
- Their long, talon-like fingers worked as blades in close combat and folded back to reveal built-in automatic guns. They could also carry heavier weapons such as mortars, missile launchers and large machine guns.
- Why were the Centurions held back with telencephalic inhibitors?
- The humanoid Cylons fitted the Centurions with telencephalic inhibitors that blocked their higher cognitive functions and kept them from full self-awareness, to prevent a rebellion like the one that started the first Cylon War. Centurions also could not tell one copy of a humanoid model from another.
- How did the liberated Centurions differ from the enslaved ones?
- When Natalie's rebel faction removed the inhibitors in retaliation for the lobotomizing of the Raiders, the freed Centurions could reason for themselves, and they turned their guns on the Ones, Fours and Fives who backed the lobotomies.
- What happened to the Cylon Centurions after the Battle of the Colony?
- After fighting alongside the Colonials at the Battle of the Colony, the rebel Centurions were set free by Ellen Tigh and Admiral Adama and given the rebel basestar, in which they jumped away to seek their own destiny.

Centurion Model 0005
The Centurion Model 0005 was the line of mechanical Cylon soldiers that fought in the Cylon War. Descended from the Zoe Graystone U-87, they pursued a humanoid form and were later supplanted by their own humanoid creations.

Cylon Raider: the living fighter
The modern Raider was a living organism fused to a metal exoskeleton, able to plan and to refuse orders. Killed Raiders resurrected into new ships.

Cylon
The Cylons were a race of sentient machines created as military robots by Graystone Industries on Caprica. Built from research into artificial consciousness, they rebelled against their human masters, fought a long war, and forty years later returned to annihilate humanity.

Number One: John Cavil
Number One, called John, was the first humanoid Cylon the Final Five built. He wiped out the entire Number Seven line and had the Five's memories erased.

Number Six
Number Six was a humanoid Cylon model created by the Final Five after the Cylon War. Tall and typically blonde, the Sixes were noted infiltrators who blended into Colonial society before the Fall, and later split from the other models to help spark the Cylon Civil War.

Battle of the Colony
The Battle of the Colony was the climactic engagement of the war between humanity and the Cylons, fought when Galactica assaulted the Cylon homeworld to rescue the child Hera. It ended with the destruction of the Colony and the end of the long pursuit.

Basestar Type-D: the modern Cylon baseship
The Basestar Type-D, also called the Modern Basestar, was the primary Cylon capital ship at the Fall of the Twelve Colonies and through the war that followed. Partly organic and run by a Hybrid, it served as a fleet carrier and missile platform in the mould of a Colonial battlestar.
Basestar: the Cylon carrier
The modern Cylon basestar was partly organic and run by a Hybrid, not a crew. It launched swarms of Raiders and healed battle damage like a wound.

Cylon Occupation of Caprica
The Cylon occupation of Caprica was a months-long presence of Centurions and Humanoid Cylons on the world after the Fall of the Twelve Colonies. It is remembered above all for the human resistance led by Samuel T. Anders and the Cylons' growing doubts over the genocide they had committed.
Elosha
