At the time of their introduction, the Republic clone troopers represented the future of galactic warfare. Far superior to battle droids, the clone troopers formed the backbone of the Republic's new military that waged war against the forces of the Confederacy of Independent Systems. So symbolic were they of the times, the galaxy-wide conflict that saw their debut took its name from their ranks: the Clone Wars.
A natural and practical leader in the clone army, Cody was a good fit for General Kenobi, to whom he was particularly loyal. Cody's keen ability to strategize, combined with his fierce combat style in the heat of battle, earned him the respect of the Jedi, and of his fellow clones as well. He often worked with Captain Rex, with whom he became friends. Cody enjoyed a close relationship with Kenobi, often sharing a tension-busting joke with him during intense moments on the battlefield. When Darth Sidious gave Order 66, however, Cody's loyalty to Kenobi was eclipsed by his clone indoctrination, and he ordered his troops to fire on the Jedi.
Clone Captain Rex served the Republic during the Clone Wars, often taking orders from Anakin Skywalker and Ahsoka Tano. He viewed military service as an honor, and he always completed his mission. Fond of using two blaster pistols at the same time, Rex customized his armor with distinctive blue markings. His loyalty to the Republic and his Jedi Generals was absolute, but even this dedicated veteran soldier found himself plagued by doubts as the Clone Wars claimed more lives and brought ruin to more worlds.
Clone Commander Wolffe (clone designation CC-3636) served under General Plo Koon in the Clone Wars, as commander of the tight-knit unit known as the Wolfpack. A seasoned and battered combatant, Wolffe has witnessed some of the worst the war has to offer. Early in the Clone Wars, he lost his entire command when Master Plo's flagship, Triumphant, was destroyed by the despicable General Grievous. Despite such tragedy, he fights on bravely, proudly brandishing his battle scars and instilling loyalty among his men.
