Dr Popjoy created Stalkers from the corpses of non-human creatures, namely birds, and contemplates making other kinds (such as whale stalkers that can bomb cities from below).
Dr Popjoy also made many non-humanoid human stalkers of strange designs.Predator's Gold said:On a T-shaped stand a big dead bird perched, watching the visitors with glowing green eyes. When Popjoy reached out a hand to it, it stretched its ragged wings and opened its beak. “As you can see,” the Engineer said, petting it, “I don’t limit myself to resurrecting human beings. Prototype Stalker-birds already patrol the skies around the Facility, and I’m considering other ideas – a Stalker-cat, and maybe a Stalker-whale that could carry explosives under a raft-city. In the meantime, I’ve been making some great strides in the field of human resurrection…”
A stalker bird easily cuts through leather and flesh.Predator's Gold said:The Engineer’s long fingers went spidering over the ivory keys, punching in a code. The lock clunked and whirred, and the door swung open to reveal a cave of ice where strange statues waited under plastic covers.
“You see, those old Stalker builders lacked imaginative flair,” explained Popjoy, his breath smouldering as he scurried around the big freezer-cabinet, unveiling his creations. “Just because a Stalker needs a human brain and nervous system, that doesn’t mean it has to be limited to a human shape. Why stick to two arms and two legs? Why only two eyes? Why bother with a mouth? These fellows don’t eat, and we haven’t built them for their sparkling conversation…” The frosty plastic sheets were dragged aside, exposing steel-plated centaurs with twenty arms and caterpillar tracks instead of legs, spider-Stalkers with clawed feet and machine-gun turrets in their bellies, Stalkers with spare eyes in the back of their skulls.
Predator's Gold said:He struck at it with his fist and his forearm and flung it away. As he hurried on up he felt pain and looked down to see blood welling out of three long cuts on the side of his hand. What sort of bird was this? Its talons had gone straight through his best leather mittens!
