Beauty and the Beast Unit

Orgins
It is yet unknown where these cyborgs were first created or when, it is also unknown if they are even cyborgs. It is unknown who created them, for what purpose, and what are their motives for being this way.

Re-Imagined For The 21st Century
From their names, and their looks, they appear to be the original Foxhound Terrorist unit that once took Shadow Moses during the Shadow Moses Incident. For one, they are not the original unit...they are a new unit that was breed for war instead of glory and power. The Unit is made of entirely of females, it is unknown for what reason.

Laughing Octopus
The original name was Decoy Octopus from Metal Gear Solid but during MGS4 it is shown in the GC Trailer that Laughing Octopus plays a bigger part with cybernetic tenticales extroduing from the back of Laughing Octopus. "Her" Ability can crush a human by simpy grasping around the person and squeezing as the person is crushed alive.

Raging Raven
The original name was Vulcan Ravenfrom MGS1 but during MGS4 it is shown in the GC Trailer that Raging Raven is shaped of a bird possibly a Raven, "Her" abilities can cut through a human torso and fire Sidewinder missiles. Raging Raven also holds either a barrel fed magazine shotgun or a grenade launcher.

Crying Wolf
The original name was Sniper Wolf from MGS1 but during MGS4 it is shown in the GC Trailer that Crying Wolf is shaped to be a wolf, "Her" abilities can stop a vehicle, and use brute force to make "her" way through a crowded section or street. "She" can also use the machine gun built ontop of "her". It is also shown that Crying Wolf can howl like an actually wolf, it is unknown if this is to mimic the GEKKOU as the way they use a cow to have the enemy lower their guards.

Screaming Mantis
The original name was Psycho Mantis from MGS1 but during MGS4 it is shown in the GC Trailer that Screaming Mantis has arms portruding from the back same as Laughing Octopus exception that they are not tenticales. Something also is unique is the puppets that dangle from these arms, on the left is one shaped like Psycho Mantis while the other is unclear. "Her" abilities is to use 'strings' and force soldiers to kill other soldiers, it is unknown what else these 'strings' can do. Screaming Mantis also has knives on the arms excluding that of the arms that hold the puppets.
