Characters/The Combine/Stalker

Stalkers are pale skinned creatures that run affairs in the Citadel.

They are human convicts, that have had their humanity stripped away from them. The reason of this is struggling in the Prisoner Pod.

They are sentient, and will only attack if another stalker is killed.

Weapons
The Stalkers have no real weapons, other than a laser grafted into their eye. they are easy to kill, and are mostly non responsive to the player.

Notable reactions
When trying to get through the Citadel in Episode One, the Stalkers reset the mechanism creating the bridge, causing it to disappear. This may have been order-driven, or it could be a sentient way to avoid getting hurt.
