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.

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.

The Confederacy of Independent Systems, also known as the Separatist Alliance, was a collection of star systems and corporate titans that left the Republic and fought for independence against the Republic’s clone armies and Jedi Knights. The charismatic former Jedi Count Dooku was the Alliance’s political leader, while its military power came from credits and assets donated by powerful galactic trade groups. No one suspected that the Alliance was actually a tool of Darth Sidious, who had engineered the Clone Wars as part of a Sith plot to rule the galaxy.

These wedge-shaped one-man starfighters were built for the Jedi Order. The Delta-7’s designers worked with the Jedi to create a starfighter for pilots with Force-aided reflexes, stripping down the fighters’ systems and making their controls as responsive as possible. With skilled pilots such as Anakin Skywalker and Saesee Tiin at the controls, Delta-7s were lightning-quick in combat, darting in for attack runs and then skipping nimbly away from retaliatory fire. During one famous encounter, Obi-Wan Kenobi piloted a Delta-7 through Geonosis’s planetary ring, pursued by Jango Fett in his starship Slave I. Plo Koon was piloting his Delta-7 above Cato Neimoidia when Chancellor Palpatine ordered the clones to execute Order 66. Plo’s wingman caught the Jedi General by surprise and blew his fighter out of the sky.
