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.
Small wedge-shaped one-man starfighters, these vessels were used by the Jedi Order in the last days of the Galactic Republic. While the ship does employ weapons, most Jedi pilots preferred to rely on their cunning and connection to the Force to avoid disputes and aggression. With the outbreak of the Clone Wars, the Jedi saw themselves pressed into the forefront of military activity, serving as generals in the campaign against the Separatists. The demands of combat saw advancements in the Jedi starfighter arsenal, resulting in modifications and a new generation of fighter craft.
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.
Serving alongside the aged Jedi Master Tera Sinube with distinction that drew the attention of the Jedi Council, M5-BZ was called upon to serve the Republic as part of D-Squad, an all-droid special missions unit led by the gruff Colonel Meebur Gascon. To carry out the vital assignment of capturing a Separatist encryption module, Beezee had its cranial memory module gutted to allow room for a mobile command center that would house Gascon.
The effectiveness of droid starfighters has been debated in strategic circles for generations. While droid starfighters are capable of maneuvers that would crush even the sturdiest organic pilot, they lack the resourcefulness and cunning that living pilots bring into combat. To counter their shortcomings, vulture droids often attack en masse. Like the ground-based battle droid infantry, vulture droids were, for a time, controlled by a central command ship, but later generations were granted a limited degree of independence. When not in flight, the droid starfighter can transform into a walking mode allowing them to be used in surface patrols.
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.
