The Reaper, a vicious alien predator, is a terror unit that is found in the company of the Floater. It is a bipedal carnivorous beast that prowls the streets of a besieged suburban town while their Floater masters watch over the terror site from high above. All had secondary control chips implanted within both of their brains, and the will of The Mind flowed in one direction, prodding the creatures on to hunt and kill. The Reaper is built to withstand ample punishment from early X-COM weapons, being somewhat resistant to armor-piercing damage, and can survive serious injury due to having two "brains" and two "hearts". When faced with advanced weapons, like a laser or plasma weapon, it is easily dispatched.
Using the Unryu Genetic Manipulation and Selective Breeding techniques Trencard Akari was able to engineer Enhanced sensory systems, better tailored for (comparatively) median-atmospheric density garden worlds, like Earth. Increased expression of instinctive pursuit mechanisms based on non-psionic cues. Unexpected sensitivity to certain plant-based chemicals identified. Deemed marginal to mission parameters.
It wears a metal harness that appears to be some sort of armor, and it attacks by rending an enemy with its sharp teeth and crushing jaws. Besides being easily killed by energy weapons, its furry coat is highly flammable, making incendiary cannon shells and rockets highly effective. Reapers have a natural sensitivity towards certain base elements, including sulfur. Since its part of their hunting instincts it was never breeded it out of them. Reapers' bodies are extremely dense and they can't swim. They won't even try. Bodies of running water terrify them. Another weakness is that the Reaper takes up four tiles, making it unable to enter a building that does not have a hole in the wall that is two spaces wide. And like all units with melee attacks, it cannot attack flying units.
