The Galactic Empire is hunting down the Jedi including Master Yoda's plucky Padawans. Aboard an Imperial Star Destroyer, an Imperial officer receives a report of Jedi activities on Geonosis. He dispatches an army of former Separatist B1-Series battle droids to the planet to investigate. An MTT transport delivers a detachment of battle droids into the Petranaki arena where they begin inspecting a modified hoverbus.
