Origin
John Walker idolized his older brother, who died in the army while serving in a South-East Asian war. Walker joined the army, but only found disappointment.  After his enlistment he sought super-powered augmentation from Power Broker, Inc. and joined the Unlimited Class Wrestling organization.  His manager convinced him to attempt to become a hero instead, and John adopted the persona of the Super-Patriot.

As a hero the Super-Patriot left much to be desired; he staged crimes that he could foil, and tried to use media leverage to replace Captain America.  Secretly manipulated by the Red Skull the Commission On Superhuman Activities (CSA) replaced Steve Rogers (Captain America I) for apparently political reasons and offered Walker the uniform and shield.  The CSA teamed Walker with a former army buddy Lemar Hoskins as Battle Star and Captain America.

Walker would later suffer a nervous breakdown following the death of his parents at the hands of the conservative vigilante group called the Watchdogs.  He become increasingly unstable, until the CSA asked Rogers to return as Captain America.

Following therapy, including memory suppression, the CSA faked Walker's assassination, equipped him with the uniform and shield Rogers clandestinely used as "The Captain," and redeployed him as U.S.Agent.
