Mace Windu was a male human Jedi Master who was the second most senior of the Jedi during the final years of the Galactic Republic, after Grand Master Yoda.

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, leading his son Boba Fett to hate Mace Windu and even try to kill him. He continued to serve the Republic throughout the Clone Wars, often leading troops into battle, despite his misgivings about the militarization of the Jedi Order.
In the final days of the war, Windu and three other Jedi confronted Darth Sidious. The three other Jedi, including Kit Fisto, were all slain by Sidious, leaving only Windu to duel the Sith Lord. Windu defeated Sidious in a difficult duel, after being informed by Jedi Knight Anakin Skywalker that Sidious and Supreme Chancellor Sheev Palpatine were one and the same person. As Skywalker rushed to the scene, Sidious lay disarmed on the edge of the window in his office with Windu holding his lightsaber on Sidious. Sidious then told Anakin that if he died he would lose Padmé as he saw in his vision, Anakin wanted to keep him alive but merely as an excuse to help him bring her back. Windu was ultimately prevented from slaying Sidious by Skywalker and forced out the window by Sidious. The Galactic Empire would later teach in its history books that Windu was the leader of a "criminal gang" who sparked the Clone Wars by interfering with a legal execution on Geonosis.
