In the final days of the Republic, the galactic government had grown so huge and corrupt that any attempt at change required radical thinking and extreme actions. Outlying systems that saw no benefit from being part of the Republic despite paying heavy taxes, began to rebel. This undercurrent of disgust towards Coruscant was seized by a charismatic leader, Count Dooku. The former Jedi rallied together these worlds in a Separatist movement that saw the departure of thousands of systems from the Republic. When Dooku's alliance was secretly backed by corporate titans that offered their unlimited droid armies to the cause, the Separatists emerged as a major threat to the Republic, and the galaxy tipped towards full scale war.
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.
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.
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.
When hunting for General Grievous on Utapau, Obi-Wan Kenobi went to the pens where Utapaun wranglers corralled native winged and wingless lizards for use as transports. He selected an obliging and brave lizard named Boga, with a leather saddle strapped to her swaying back. She stood four meters tall at the shoulder, and had a pebbled skin with an iridescent green and blue sheen. A crown of richly colored feathers fringed her head and neck, trailing away from her beaked face and keen eyes. Her powerful limbs ended in five-toed feet, tipped with curved claws providing excellent purchase on the sandstone surfaces. A long tail aided in balance and agility.
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.
