Raiden, real name Jack, also known as Jack the Ripper, White Devil, and Snake, was a Liberian-American mercenary and former special forces soldier. Previously a child soldier under Solidus Snake, Raiden was later selected by the Patriots to test the S3 Plan at the Big Shell, as a new recruit to the reformed FOXHOUND unit. He later worked alongside theParadise Lost Army in their anti-Patriot activities, but was captured and forced to undergo heavy cybernetic experimentation. After successfully escaping, Raiden went on to assist Solid Snake during the Guns of the Patriots Incident.
Jack was born on a rainy day in Liberia. During his youth, in the turbulent period that was the First Liberian Civil War, Jack was adopted by Solidus Snake, who became his godfather after he killed the former’s parents. Jack was subsequently raised as a child soldier and later fought in the country’s Civil War in 1989. He and other children were shown Hollywood action films daily for “image training,” and were given food mixed with gunpowder containing toluene to make them more controllable.
In 2014, Raiden reappeared in South America, revealing himself to Solid Snake by Codec to warn him of an enemy PMC ambush. Disavowing his identity as Jack, Raiden updated Snake as to his dealings with the Paradise Lost Army, before the call was interrupted due to a firefight. Shortly after Snake defeated the PMC commander Laughing Octopus, Raiden contacted him again to provide help in tracking down Naomi Hunter, using his knowledge of scouting. Raiden later assisted in Snake and Naomi’s escape by helicopter, by fighting off several Gekko units at a local marketplace. Removing the black duster that concealed his cyborg appearance, Raiden was able to disable the attacking Gekko using his enhanced agility and swordsmanship, employing a high-frequency blade.
