Luminara Unduli served the Jedi order in the final years of the Galactic Republic. A green-skinned female humanoid, Luminara was a trusted advisor to the Jedi Council and the Republic government. When crises demanded it, she and her faithful Padawan learner, Barriss Offee, would rush into the thick of conflict, where their incredible talents with the lightsaber blade served them well. Luminara is a model Jedi Knight -- she has mastered control of her emotions and her physical abilities.
Luminara worked with Ahsoka Tano during the transport of prisoner Nute Gunray from Rodia. Luminara was surprised at how undisciplined Anakin Skywalker's Padawan could be.
Luminara entrusted the security of Nute Gunray to Captain Argyus, a move she would come to deeply regret.
Viceroy Nute Gunray was captured on Rodia, and transported to Coruscant aboard Luminara's flagship, Tranquility. The desperate Neimoidian pleaded for his life, and attempted to bribe his captors, though Luminara has absolutely no use for material wealth.
Luminara and Anakin Skywalker worked closely together during the battle to retake Geonosis. They led the charge of clone troopers to destroy Poggle the Lesser's new supertank brigades, stalling the Separatist advance while their Padawans destroyed the Geonosian weapons factory.
Luminara's appointed clone commander is a soldier named Gree. The two would work together during the Kashyyyk campaign at the end of the Clone Wars.
