A resourceful astromech droid, R2-D2 served Padmé Amidala, Anakin Skywalker and Luke Skywalker in turn, showing great bravery in rescuing his masters and their friends from many perils. A skilled starship mechanic and fighter pilot's assistant, he formed an unlikely but enduring friendship with the fussy protocol droid C-3PO.
Though the clone troopers embodied the war effort of the Galactic Republic against the Separatist Alliance, victory was reliant upon valiant patriots of all shapes and sizes. Meebur Gascon answered the call of duty at the very start of the conflict, and offered his keen analysis as part of Strategic Command since the Battle of Geonosis. The Jedi Council placed Gascon in command of D-Squad's mission to obtain a vital Separatist encryption module. No-nonsense and military-minded with an outsized personality and gruff voice, the diminutive Gascon balked at any suggestion that he was simply a map reader, or that his D-Squad assignment was a result of his tiny size.
The Republic attack cruiser was not primarily a cargo transport, troop carrier or other replenishment or supply vessel; it was developed and honed for ship-to-ship combat. Its huge armored shape had an aggressive, dagger-like profile, studded with heavy weapons emplacements capable of punching through powerful shields and sturdy armor. The front half of the ship's spine contained a massive flight deck capable of scrambling the latest in Republic starfighters. The huge hangar doors opened to allow ships to land or takeoff from the deck; the vessel also had a smaller docking bay entrance on its lower side.
A clever if flighty pit droid programmed in piloting, WAC-47 served as part of the 91st Recon Corps, reporting to Clone Commander Neyo. He was drafted into service as part of D-Squad, a special missions group of droids assigned by the Jedi Council to recover a vital Separatist encryption module. WAC-47 did not always see photoreceptor-to-eye with the mission's commander, Colonel Meebur Gascon, who treated the loyal droids as property. WAC-47, who seemingly had a program glitch that was unable to properly register the colonel's rank as anything other than "corporal," insisted Gascon treat D-Squad with the respect they deserved.
An insidious weapon unveiled by the Separatist Alliance during the later stages of the Clone Wars, buzz droids are tenacious saboteurs launched onto enemy starfighters via specialized missiles. They emerge as spheres and attach themselves to a target vessel, popping open to reveal an insect-like droid equipped with cutters and other tools of vandalism. The buzz droids are designed to disable, not destroy, enemy craft. They operate quickly, slicing into starship hulls. While their tools are effective, a hit to its central eye can knock a buzz droid out of commission.
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.
