CC-2224, nicknamed «Cody,» was a Clone Marshal Commander in the Grand Army of the Republic who commanded the 7th Sky Corps—including its renowned subunit the 212th Attack Battalion—during the Clone Wars. He served as the second-in-command of High Jedi General Obi-Wan Kenobi within the Third Systems Army and the 7th Sky Corps. General Kenobi found the commander to be reliable, trustworthy and loyal, with his abilities as a soldier and strategist earning Cody the respect of both his Jedi superiors and fellow clone troopers.

During the final years of the Republic Era, Cody was created as part of an army of genetically-identical soldiers bred from the template of Jango Fett, a human bounty hunter, and conditioned for absolute loyalty to the Galactic Republic. Once deployed from the clone homeworld of Kamino, Cody served in several major battles against the Confederacy of Independent Systems, such as the Battle of Christophsis, the Second Battle of Geonosis, and the Battle of Anaxes. In addition to General Kenobi, Cody formed a friendship with Clone Captain CT-7567 «Rex,» a fellow clone trooper officer who served in Jedi General Anakin Skywalker‘s 501st Legion.

Following the Battle of Coruscant, the Jedi High Council deployed Cody’s battalion to the planet Utapau, where General Grievous and the Separatist Council had taken refuge. His troops overwhelmed the Separatist Droid Army while Kenobi engaged Grievous, destroying the cyborg general and effectively ending the Clone Wars. As the Battle of Utapau continued, Cody carried out an action that proved to be his most enduring legacy: he was the man to order Kenobi’s death, albeit not by choice. The Clone Commander received a transmission from Supreme Chancellor Sheev Palpatine, secretly the Dark Lord of the Sith Darth Sidious, who instructed him to execute Order 66. Controlled by the secret programing implanted into him and all his clone brothers by the Sith, Cody was forced to turn against his longtime general and friend but ultimately failed to kill him. Nevertheless, his service continued under the reign of the Galactic Empire by assisting in the final enslavement of Kashyyyk.
