The Colonel was an AI recreation of former FOXHOUND commander Roy Campbell, produced by multiple AIs under the Patriots' control during the Big Shell Incident.

///

Posing as Raiden's commanding officer during the Big Shell Incident, the Colonel was a combination of GW's AI and Raiden's "expectations" of Campbell (when Raiden used the Codec, GW was able to access his brain through the nanomachines, thus creating memories and situations based on actual experiences, so Raiden couldn't tell the difference). The Colonel was designed to lead Raiden through the Patriots' S3 Plan. During the events of Raiden's mission, the Colonel also lied to Raiden about several of the events of the mission, namely that the Sons of Liberty demanded a ransom of $30 billion in cash, their murdering a hostage on top of the Big Shell in retribution for thwarting the C4 demolition plan, and that blowing up the Big Shell would result in a chloride holocaust. Most of the lies were in an attempt to mirror the Shadow Moses Incident as part of the S3 Plan.

Emma Emmerich eventually uploaded a virus onto Arsenal Gear's systems, which caused the Colonel to start acting very strangely. When Raiden remembered that he never even met the Colonel once, the Colonel signed off, although not before implying that the Patriots were holding Rosemary hostage as leverage against Raiden. During the infiltration of Arsenal Gear, Otacon concluded that the Colonel was in fact an advanced AI and not a real person. Under the effects of the virus, the Colonel attempted to "dissuade" Raiden from continuing his mission, claiming that the Sons of Liberty were holding Rose hostage in the holds of Arsenal Gear, although Solid Snake told Raiden that it was a trick. The Colonel AI was eventually deleted by the virus.

However, after Arsenal Gear crashed into Manhattan, another AI of the Colonel and Rose contacted Raiden, announcing the true intentions of the S3 Plan: manipulating history and individuals and censoring the digital flow of information, as well as telling him that the S3 Plan was a resounding success thanks to Raiden. The Colonel ordered Raiden to kill Solidus Snake; if Raiden either refused or died, the Patriots would terminate Rose, their unborn child, and Olga Gurlukovich's daughter Sunny. Midway through the fight, the Colonel alongside the Rose AI contacted Raiden to goad him into finishing off Solidus. When Raiden tried to reason with them, the Colonel and Rose AIs implied that they ultimately viewed all of humanity as being tools to be discarded once their usefulness was at an end, as well as everything being a game to them.
