30 Sec Answer: Mace Windu never had a Padawan, though he was often speculated to have trained Anakin Skywalker.
Introduction
Mace Windu is one of the most popular and well-known characters in the Star Wars universe. He is a powerful Jedi Master who fought alongside Obi-Wan Kenobi, Yoda, and other members of the Jedi Order during the Clone Wars. But did Mace Windu ever have a Padawan? In this article, we’ll look at the evidence that exists for whether or not Mace Windu had a Padawan.
The Evidence
The first piece of evidence that points to Mace Windu having no Padawan comes from his dialogue in Star Wars Episode II: Attack of the Clones. During his conversation with Obi-Wan Kenobi and Anakin Skywalker about training Anakin as a Jedi, Mace says "I do not have time to train you". This implies that he has neither taken nor trained any Padawans before.
The second piece of evidence comes from the canon novel Shatterpoint by Matthew Stover. In it, there is an exchange between Mace and his former Padawan Depa Billaba in which Mace tells her that "I have never taken an apprentice" and she responds by saying "I know". This further confirms that Mace has never taken on any Padawans before.
Finally, there are also some hints in various Expanded Universe materials that suggest Mace may have once been responsible for Anakin Skywalker’s training. These include him being mentioned as Anakin’s master in the video game Jedi Power Battles and also being referred to as Anakin’s teacher in the novel Labyrinth of Evil. However, none of these sources provide concrete evidence either way so it remains speculation as to whether or not Mace actually trained Anakin himself.
What We Know For Sure
What we can say for certain is that Mace Windu has never officially taken on or trained any Padawans during his time in the Jedi Order. His dialogue in Attack of the Clones implies he does not have the time nor inclination to do so, while both canonical and expanded universe sources confirm this fact without a doubt.
As far as speculating whether or not Mace ever unofficially took on Anakin Skywalker as a student is concerned, there are several pieces of evidence that suggest he may have done so but nothing definitive enough to confirm it either way.
Conclusion
To sum up, it appears that Mace Windu did not take on any official Padawans during his tenure as a member of the Jedi Order but there is some evidence suggesting he may have unofficially trained Anakin Skywalker prior to his fall to the dark side. Ultimately though, we can only speculate as to whether or not this is true given how little concrete evidence exists surrounding this subject matter.
