Omega Sentinels (G1)

The Omega Sentinels (オメガ・センチネル, Omega Senchineru) were once the peacekeepers of Cybertron, powerful giants that guarded cities and quelled uprisings. The Omega Sentinels gave the Decepticons much trouble at the outbreak of the Third Cybertronian War, but by the modern era they were no longer so prevalent.

The most notable surviving Sentinel is Omega Supreme, who is the only one seen to have his own name, distinct color scheme, and personality; it is unknown how unique these qualities actually are.

History
When the Quintessons ruled over Cybertron, they employed Dark Guardians against the growing Autobot insurgency. By the time of the Golden Age millions of years later, the Autobots themselves were using their own Guardian robots they have named, Omega Sentinels (visually identical to the Dark Guardians except for their colors), to maintain supremacy. When Megatron's uprising began, his troops feared the giant enforcers, but in time they eventually fell before the Decepticon onslaught.

One tool Megatron used in his strategy was the Robo-Smasher, a brainwashing device. He used it to turn the Combaticons to his side, then he had them destroy Crystal City. The city's Omega Sentinel, Omega Supreme, was heartbroken and enraged by this betrayal, especially because he had been friends with the Combaticons. He tracked them down and reprogrammed them to be free of the Robo-Smasher's influence, but he was not thorough enough. They feigned rehabilitation, but only long enough to lure Omega into a trap. Megatron had given them a combiner mode, Bruticus, which they used to pin Omega against a wall while the Robo-Smasher pounced on him. The Sentinel was able to destroy the machine, but it left him a taciturn, vengeance-driven shell of his former self.

Synopsis
Millions of years later, after escaping an Autobot attack on their time machine facility, some Decepticons found the remains of a decapitated Omega Sentinel. Skywarp said that it gave him the creeps, and Thundercracker remarked on how the Omega Sentinels had given them a pounding in the old days. Shockwave repaired the giant and sent it into battle against the Autobots, lamenting that the lack of a head would limit its maneuverability. Nevertheless, it was a formidable foe for Optimus Prime and his small team; the tide was only turned with the arrival of the Aerialbots. The Sentinel was able to put up a strong fight against Superion at first, but the combiner eventually destroyed it.
