- The Centurion Droids are non-sentient drones from the Generation 1 continuity family.
We make Sentinel units look smart.
The Centurion Droids are an automated defense guarding the Vector Sigma supercomputer. Though posessing no weapons, Centurions are trained in hand-to-hand combat to stop all intruders. They also possessed very strong armor that protected them from attacks making them even more dangerous. They tend to be encountered in large numbers.
They must be either evaded or tricked to approach Vector Sigma- fortunately that's not hard.
Fiction
Generation 1 cartoon
The Centurion Droids were first encounted deep within planet Cybertron, guarding the chamber of Vector Sigma from both Autobots and Decepticons. Megatron was able to by-pass them by using the Key to Vector Sigma to override their defenses, but Optimus Prime and his Autobots were not so lucky. Unable to defeat the Centurions in combat, the Autobots kept them busy with a slew of ancient worker droids. The worker droids stumbled off the edge of a chasm leading the Centurions to follow like lemmings.
The Headmasters cartoon
The Centurion Droids were encountered by Optimus Prime again in the year 2011, as Prime was one another mission to reach Vector Sigma. However, this time around, the Centurions did not appear to be nearly as threatening, as Prime simply plows through them like an American football player.
IDW comics
Greatly upgraded Centurion Droids were employed by Bludgeon and his crew to prevent disruption of their resurrection of Thunderwing and their study of the Pretender graft process. The upgraded droids bear a more than passing resemblance to Vehicon Tank Drones.
