Master Mace Windu is a major supporting protagonist in the Kingdom Hearts Unlimited Saga, first appearing in "Birth of A New Era" taking on part of the role originally filled by Eraqus.
Hailing from the world of Haruun Kal, Mace Windu served as one of the last members of the Jedi High Council before the Fall of the Republic. Serving on the Council, Windu was often regarded as second only to the Grand Master Yoda, though Windu was eight centuries Yoda's junior. Windu's wisdom and power were considered legendary by many, as were the weight of his words. Trained as a Jedi Guardian, Windu was considered to be one of the best swordsmen in the history of the Jedi Order and had created the modern seventh form of lightsaber combat, Vaapad along with fellow Jedi Sora Bulq. Windu served the Jedi Order his entire life, training several Jedi in return.
It was Master Windu who led two hundred and twelve Jedi into combat at the Battle of Geonosis and slew the infamous bounty hunter Jango Fett. He continued to serve the Republic throughout the Clone Wars, often on the frontlines of fierce fighting, where he led Republic forces as a High Jedi General. He would distinguish himself across many battlefronts, most notably on Dantooine, though he would distinguish himself on Ryloth, Null, Boz Pity and Haruun Kal amongst others. In the final days of the war, Windu confronted and cornered Darth Sidious in a difficult duel, after being informed by Jedi Knight Anakin Skywalker that Sidious and Supreme Chancellor Palpatine were the same person. He was ultimately betrayed by a reluctant Skywalker and subsequently killed by Sidious, falling to his death from the window of Sidious's office.
