Beauty and the Beast Unit

The Beauty and the Beast Unit (also known as the BB Corps. and once referred to as SNAKEHOUND) were a unit of female soldiers who were given special suits to turn them into incredible soldiers, after each one suffered from intense Post Traumatic Stress Disorder caused by horrors of war. This made them potentially invincible soldiers, causing them to be exploited for their skills. Although their damaged minds give them a momentous edge in combat, it is also their greatest weakness.

During the Guns of the Patriots incident, they were convinced their goal was to destroy Solid Snake, believing it would ease their anguish, and make them "whole" again. Snake fought and defeated each of the members of the unit in turn, usually when they were accompanied by a small unit of the FROGS.

Regardless of whether Snake killed them or not, Drebin's comment that they can only survive outside of their suits for only a few minutes, makes certain that they died. When out of their suits, they start having a nervous breakdown and reliving their respective traumatic moment. This is most likely due to their fragile mental state.

Trivia

 * During development of MGS4, Hideo Kojima wanted the Beauty and the Beast Unit to be naked, though this would have severely affected the game's censorship rating. Yoji Shinkawa stated that the motion capture actors were asked to do the motion capture nude, though this could also not be used in the game.
 * The Beauty and the Beast Unit is a somewhat tribute to the bosses of the Metal Gear Solid games; as a result the name of each member of the Beauty and the Beast Unit is derived from the name of a member of FOXHOUND (from Metal Gear Solid), their weapons are a derivative of Dead Cell members' weapons (from Metal Gear Solid 2), and their emotions similar to the Cobra Unit member codenames (from Metal Gear Solid 3):
 * Laughing Octopus - Derived from the camouflage and name of Decoy Octopus, the P90 submachine gun and tentacles of Solidus Snake and the emotion of The Joy.
 * Raging Raven - Derived from the name and flying accomplices of Vulcan Raven, the explosives of Fatman and the rage of The Fury.
 * Crying Wolf - Derived from the name and fighting style of Sniper Wolf, the railgun of Fortune and the emotion of The Sorrow.
 * Screaming Mantis - Derived from the name of Psycho Mantis, the thrown knife weapons of Vamp and mixture of The Fear and The Pain.
 * Note also that each of the members of the BB Corps appears in reverse chronological order of their namesake's boss fight in MGS1 (Ocelot, Mantis, Wolf, Raven, Octopus). Note that Octopus is last on the list because Vulcan Raven divulged Octopus' identity as the fake Donald Anderson after beating him, and Octopus never actually fought Snake. Laughing Octopus may also have been put first since she is also a tribute to the final bosses of MSG2 & 3 (Solidus and The Joy/Boss).
 * The boss music, BB Corps, also mimics this tribute- boss music from each Metal Gear Solid game can heard played backwards in certain parts of the music&mdash; for example, in the introduction, it begins with a beat in a similar manner to Yell "Dead Cell", only somewhat slower and softer, then violins play a slow, calm, backwards version of Encounter, then finally it leads to the main theme with an electric guitar mimicing "The Fear"'s peircing opening in a noticably softer manner (probably since The Fear was the only Cobra fought in the jungle, where most of the game takes place, who had boss music).
 * If The Beast form of each of the unit is defeated non-lethally (with the exception of Screaming Mantis, due to the nature of the battle with her Beast form), a statue of their Beast form can be found and obtained during the "Beauty" stage of the battle. Collecting all four (as well as the FROG Statue) will unlock the Solar Gun, a reference to one of Hideo Kojima's other games, Boktai.
 * Similarly, FaceCamos of each of the Beauties can be unlocked by defeating their respective Beauty forms non-lethally.
 * When their Beauty form are advancing upon the player, not killing them for several minutes will result in transportation to an infinitely sized White Room, with a three minute timer. It is impossible to call Otacon or Rosemary while in this room. Equipping the camera will cause the Beauties to pose. If the player selects and de-selects the camera, they will change their pose. Equipping the iPod and playing "Oishii Two-han Seikatsu" will make them dance.
 * Game Informer ranked the Beauty and the Beast Unit #5 in their list of the top 10 villians of 2008.
