Synth

A Synth is a non-sapient species of creatures synthesized from a combination of Human and alien DNA.

Synths were created in prehistoric times and abandoned on Earth by their creators. They inhabit the Laurentian Forest in Canada.

Biology
Synths are large reptilian creatures with curved claws and no eyes. They're facultative bipeds, and occasionally engage in knuckle-walking, like gorillas.

Synths produce sonic screams that can incapacitate and render Humans unconscious. The Synths themselves are not immune to the sound's effect, which can be used against them if played back by a recording device. They make nests in caves and hunt down prey to feed their young. Victims are taken alive and hanged upside down to the cave's ceilings by a sticky slime-like substance.

Synths are viviparous and may give birth to twins. They're born fully-developed and ready to assist the parents in their hunts.
