Ki-Adi-Mundi was an alien representative who sat on the Jedi Council. A humanoid being, Ki's most distinguishing physical feature was an enlarged conical cranium that contained a binary brain.

When Jedi Master Qui-Gon Jinn reported a Sith attack during the events surrounding the Battle of Naboo, Ki-Adi-Mundi expressed shock at the notion. "Impossible," he remarked, "the Sith have been extinct for a millennium."

For its failure to detect the Sith menace in time, the Jedi first suffered the loss of one its greatest Masters, Qui-Gon. Ki-Adi-Mundi voyaged to Naboo to attend Jinn's somber funeral, and was also present at the jubilant celebration that marked the liberation of Naboo.

A decade later, Jedi Master Ki-Adi-Mundi continued to serve on the Council. He was present during one of the gravest crises ever to face the Jedi order: the Separatist movement that threatened to split the Republic. Like most in the order, Ki-Adi-Mundi refused to believe that the movement's architect, former Jedi Count Dooku, was behind its more violent actions. As a political idealist trained in Jedi philosophies, such acts would be beneath Dooku, Ki-Adi-Mundi reasoned.

Ki-Adi-Mundi was not the only Jedi to be mistaken about Dooku's limits. The former Jedi oversaw the scheduled execution of Obi-Wan Kenobi, Anakin Skywalker and Senator Padm� Amidala. The sudden arrival of a Jedi taskforce -- including Ki-Adi-Mundi -- rescued the three captives. Ki-Adi-Mundi and several of his fellow Jedi Council members did battle with Geonosian and Separatist droid forces. While the Jedi were prepared to handle the Geonosians, they were surprised by the immensity of the Separatist droid army. Many Jedi died that day, though Ki-Adi-Mundi was one of the survivors.

When Republic reinforcements arrived, Ki-Adi-Mundi hopped aboard a Republic gunship, and later led units of clone troopers into the thick of combat. The war-scorched flats of Geonosis became the first battleground of the devastating Clone Wars.

Like his fellow Jedi, Ki-Adi-Mundi became a general in the Clone Wars, leading clone trooper infantry on campaigns scattered throughout the galaxy. He still retained his high position on the Jedi Council, remotely attending council sessions via hologram.

During the Outer Rim Sieges, as the Clone Wars were nearing their end, Ki-Adi-Mundi was stationed on the Banking Clan stronghold world of Mygeeto. There, he led the Galactic Marine clone troopers with Commander Bacara.

He stayed in touch with Coruscant as the Jedi Council was experiencing the changes initiated by Chancellor Palpatine. He grew wary of the Chancellor and his bids for increased executive power. When the upper tier of the Jedi Council -- himself, Yoda and Mace Windu -- discussed a possible course of action to remove the Chancellor, Ki-Adi-Mundi advised that the Jedi order would have to take control of the Senate in the interim, to ensure a secure transition of power. Taken out of context, such discourse would be branded treason -- it was a disturbing sign at just how unstable the democracy of the Republic had become.

The transition never happened due to the machinations of the Chancellor. Palpatine initiated Order 66, the ultimate endgame contingency against the Jedi. The order, transmitted secretly to the clone commanders spread across the galaxy, identified the Jedi as traitors to the Republic. Commander Bacara and his marines opened fire on Ki-Adi-Mundi. Though the Jedi attempted to put up a defense, he was overwhelmed by the gunfire and killed.
