Fiction

Generation 1 cartoon

After Spike Witwicky and Carly arrived at Decepticon Headquarters on Cybertron via Space Bridge, they quickly escaped from Shockwave's control room. The guardian of Cybertron then dispatched "the Sentinel" to deal with the humans; thinking fast, Spike crushed its head in a giant sliding door, destroying it. DotD2

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 it tracked them to the general vicinity of their secret headquarters, this Sentinel was obliterated by a single blast from Moonracer's pistol. TSfAT

Holy God, you're heavy, boss! Why can't you shrink like everyone else?

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 manevuers with giant holograms. These Sentinels were present when an asteroid arrived on Cybertron carrying the banished Combaticons. 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. TRoB
