"On my God, its a Stalker cart." - Alyx Vance
The Stalker is a normal human being, tortured and mutilated by the Combine. A majority of their brain function has been removed, their limbs have been replaced with metal parts, and most of their body has been distorted. The sole purpose for these creatures is to do the grunt work for their Combine masters.
