The name or term Sentinel refers to more than one character or idea. For a list of other meanings, see Sentinel (disambiguation).


For some reason, fhe first Sentinel had gardening shears for hands.

The Sentinels are a group of Decepticon drones from the Generation One continuity family.

The Sentinels were a series of combat robots used by Shockwave on Cybertron. None of them appeared able to speak or transform, but they sure did die easily.


The Transformers cartoon

After Spike Witwicky and Carly arrived at Decepticon Headquarters on Cybertron via Space Bridge, they quickly managed to escape from Shockwave's control room. The guardian of Cybertron then dispatched "the Sentinel", a treaded robot with pincer-like hands, to deal with the humans. Thinking fast, Spike crushed its head in a gigantic sliding door, destroying it. Desertion of the Dinobots, Part 2


On Cybertron, everything is aerodynamic.

Later, when Chromia, Firestar, and Moonracer escaped capture at Shockwave's hand, he sent a different Sentinel, which was capable of flight, after the trio of fleeing female Autobots. Though the wheeled, multi-gunned machine tracked them to the general vicinity of their secret headquarters, this Sentinel was obliterated by a single blast from Moonracer's pistol. The Search for Alpha Trion

When next encountered, Shockwave had a large group of "Sentinel guards"—of a different make from the last two units—which he deployed in practice military maneuvers with giant holograms. These Sentinels were present when an asteroid arrived on Cybertron carrying the banished Combaticons.


Minutes from agonizing death, rest assured.

Shockwave and the Sentinels defended the planet from these renegades, who combined into Bruticus and utterly decimated them. A short while later, the Sentinels assisted a joint Decepticon-Autobot task force in defeating the giant Bruticus, although many more were reduced to scrap in the process. The Revenge of Bruticus


  • The Sentinel that appeared in "The Search for Alpha Trion" was actually a re-used robot model from "Desertion of the Dinobots, Part 2". Presumably this means the original robot in DotD was one in a series, as Shockwave disintegrated it shortly after Spike and Carly tried to used it as cover.
  • The army of Sentinel guards that appear in "The Revenge of Bruticus" likewise re-use a model from "Desertion of the Dinobots, Part 2". In this case, they recolored the model of the Head Guard, who was turned into molten metal by Slag.
