A legendary Jedi Master, Obi-Wan Kenobi was a noble man and gifted in the ways of the Force. He trained Anakin Skywalker, served as a general in the Republic Army during the Clone Wars, and guided Luke Skywalker as a mentor.
General Grievous was a brilliant Separatist military strategist and a feared Jedi hunter, known for his ruthlessness and hacking cough. His body itself was a weapon, allowing him lightning quick strikes and devastating blows. But he was also quick to run from a fight, a tactic that worked until one final meeting with Obi-Wan Kenobi.
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.
Ringed by numerous moons, the remote sanctuary of Utapau is a planet pitted with enormous sinkholes. Its windswept surface is dry and desert-like, but deep in the porous crust, at the bottom of the sinkholes are pools of life-giving water. Many of the sinkholes on one of the planet's small continents are lined with intricate cities that stretch deep into caves and crevices beneath the planet's surface, as well as mining operations that seek to uncover valuable minerals from the planet's depths.
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.
Greeting Obi-Wan Kenobi during his search for General Grievous on windswept Utapau was Port Administrator Tion Medon. The tall, gaunt Utapaun initially feigned ignorance about Grievous' whereabouts, but then whispered a warning to Kenobi. Grievous was indeed on the planet, hiding on the tenth level of the sinkhole city with an army of thousands of battle droids.
