Paradise Lost
From the Metal Gear Wiki
The Paradise Lost army was an anti-Patriots group formed by Big Mama, also known as EVA. The group was made up of war orphans (similar to Big Boss's Zanzibar Land which was also home to war orphans rescued by him). The group's name is a reference to Paradise Lost, John Milton's famous poem.
The Paradise Lost army worked closely with Raiden following The Manhattan Incident, helping him rescue Sunny from a Patriots hideout. In exchange for the information, Big Mama requested Raiden hunt down the remains of Big Boss, who was being kept alive by The Patriots. In attempting to do so, Raiden was captured and kept in Area 51 where he was severely tortured. The Patriots used him as a guinea pig for their experiments in exoskeletal enhancement surgery, during which part of his head was severed at the jaw and transplanted to an entirely synthetic body, similar to the experiments conducted on Gray Fox years earlier. Raiden was later rescued by Paradise Lost, who succeeded in acquiring the remains of Big Boss. At an unknown point in time, they also managed to acquire Solidus Snake's body and often used it as a decoy after removing his arms, legs, and most of his skin and bodily organs.
[edit] Liquid Ocelot's Insurrection
See Liquid Sun, Solid Sun, Third Sun, Twin Suns, Old Sun and Naked Sin
The PMC Raven Sword swiftly trapped Paradise Lost in Eastern Europe and attempted to steal the body of Big Boss from them for Liquid Ocelot who required the body in order to gain control of the SOP System.
Solid Snake attempted to find Big Mama before Liquid could get a hold of Big Boss' remains, unknowingly leading Raven Sword right to their hideout. After a harrowing motorcycle chase with a decoy van, they crashed, and Big Mama was severely injured. With Big Mama dying and all of the members slaughtered, the FROGS found the real van and stole the body, allowing Liquid Ocelot to gain control of the System.
However, it was later revealed to Snake that the body Ocelot had stolen was not Big Boss, but Solidus Snake. Ocelot succeeded either way because the body was an exact genetic duplicate of Big Boss, but Paradise Lost were earlier able to rebuild Big Boss using the real body and pieces from Liquid Snake and Solidus.
