"The Last Battle" Episode Guide | Star Wars Rebels - S3 E6

Early in the Clone Wars, the Separatist droid army was often led into war by analytically minded tactical droids. Before long, the Republic was able to outmaneuver the tactical droids by exploiting their reliance on precise calculation and lack of imagination when dealing with the unexpected. Furthermore, the droids were spindly mechanics whose heads could be yanked off and scoured for vital combat data. Super tactical droids, like General Kalani, were an improvement over the standard tactical droid. Kalani's advanced processors and robust frame made him a threat to be reckoned with.

A barren world of frost and rock, Agamar was the site of a Clone Wars battle between the Republic and Separatists. Years after the end of the war, Clone War veteran Captain Rex and a band of rebels visited the planet searching for weapons, and encountered a still-active reserve of Separatist droids. The Super Tactical Droid commander demanded they have one last battle to decide the war, but the groups ultimately joined forces to take on a common enemy: the Empire.

Super Tactical Droids were highly intelligent and strategic, qualities that enabled them to be masterful commanders for the Separatist Army in the Clone Wars. Kalani, a notable Super Tactical Droid, prevented Darth Sidious’ shutdown command following Order 66. Years later, Kalani and his battle droids were found by clone Captain Rex and his rebel friends, and the two sides joined forces against the Empire.

Small and defenseless, the Sheathipede-class shuttle was nonetheless an effective transport. Its defining characteristic was a large topside fin, enabling it to bank quickly. The craft was just large enough to fit a small crew, making it an ideal ship for battle droids during the Clone Wars.

A repurposed Neimoidian Sheathipede-class shuttle, the Phantom II is an auxiliary vessel nested in the hull of the Ghost freighter, used for short-range travel.

Rex once served the Republic on the frontlines during the Clone Wars, taking orders from Anakin Skywalker and Ahsoka Tano as first a captain and later a commander. He viewed military service as an honor, and his loyalty to the Republic and his Jedi Generals was absolute. But when Order 66 was executed, it was Ahsoka who helped to free Rex from the programming of his inhibitor chip. At the dawn of the Empire, Rex has escaped with his life but is considered killed-in-action in the eyes of the new regime. That allows him to operate in the shadows and help any clone brothers who remain separate from the Imperial ranks.
