Mooks who have been enslaved. If they aren't brainwashed they normally rebel, if only in small numbers (due to fear). Normally played to tug at those tug-proof heartstrings. 9 times out of 10 the brainwashed version won't rebel, and any supporting characters are depressed by their existence.

Examples

• The Grunts in Halo serve as a sometimes brainwashed version of this trope, and are used as comic relief no less.
• Another Halo example is the Flood Combat and Carrier forms. They don't WANT to be that, but they are forced to by the Infection Form. An enslaved and forced, but not brainwashed, version of this trope.
• The Stalkers in Half Life 2. They are a version of the brainwashed type.
• Like the Flood example above, the Zombies in Half-Life are the same.
• The Titan Monsters in Batman Arkham Asylum may be this, but Poison Ivy's minions are this for sure, as they are mind controlled.
• Mass Effect has the Husks, a slave mook of the Geth. They are mindless killing machines.
• Most Sonic The Hedgehog games have the little robots, where the slave is the fluffy animal inside.
• Spider Man Web Of Shadows has the symbiotes, which Spidey kills without any What The Hell Hero speaches.
• A Movie version of this is the Evil Dead deadites, which are possessed (In the first 2).
• Doom has it's zombies, slaves to Hell.
• Most robot mooks, period.

There is more, but I don't feel like listing them right now.
