Body-Snatcher

Body-Snatchers, also known as Snatchers or Bioroids, were a paranormal entity that menaced Cuba and intended to menace the entire world in late 1974, early 1975.

Biography
At some point, a Body-Snatcher had somehow boarded a Soviet-owned commuter jet, and sent it crashing in close proximity to the United States Naval Facility in Cuba. The Body-Snatcher escaped the wreckage before it sunk to the ocean floor, and proceeded to take over most of the stationed personnel at the base. The surviving personnel proceeded to request for assistance, eventually resulting in the hiring of the private military company Militaires Sans Frontieres to investigate. The leaders of the MSF, Kazuhira Miller and Big Boss, after being briefed on the situation, proceeded to utilize a secret weapon: Raiden, a cyborg from the distant future, because his near-completely mechanical body rendered him immune to the Body-Snatcher's ability to take him over. Raiden was then dispatched to exterminate all Body-Snatchers, and to neutralize any surviving, non-taken-over personnel at the base.

Abilities
The Body-Snatchers utilized asexual reproduction to infect people, as evidenced by the Body-Snatchers managing to take over nearly the entire base with solely one Body-Snatcher. They could also absorb their victims memories and thus steal their identities. The process was also implied to kill their hosts, leaving them only as shells. Their true forms are very angular to the point of being almost skeletal, with their faces being gaunt and harboring immense eyes. When killed, they release a green aura that consumes the bodies they possessed.

Behind the scenes
Body-Snatchers were characters in the Xbox 360/Xbox ONE exclusive mission "Jamais Vu" for Metal Gear Solid V: Ground Zeroes. Their names bore large resemblance to the titular biomechanical creatures from Kojima's game series Snatcher, which also stole identities from people. Their names and overall nature also resembled that of the body-snatchers from the 1956 science fiction film and 1978 remake Invasion of the Body Snatchers, dealing with an extraterrestrial pod-like race that took over various humans.
