Perhaps Mace Windu survived and was captured by the Empire. He manages to escape during the events of Star Wars Rebels. He then teams up with the Ghost crew. His presence would be a huge boost to their morale, as he is a powerful and well - respected Jedi. He could also help in the fight against the Inquisitors, using his skills to outwit them.
In a fanfiction scenario, Mace Windu could have been in exile on a remote planet during Star Wars Rebels. He hears about the Rebellion and decides to make his way to them. Once he joins, he starts to train the young Jedi and non - Jedi alike in the ways of the Force. His knowledge of the Jedi Order before its fall could be used to reform and strengthen the new Jedi movement within the Rebellion.
He could be a Force - ghost. His spectral form could guide Kanan or Ezra at crucial moments. For example, when they face a difficult decision regarding the Dark Side, Mace Windu's Force - ghost could appear and offer his wisdom based on his own experiences with the Sith.
Yes, there are quite a few. Some focus on Mace Windu's journey after surviving, perhaps seeking revenge on Palpatine or reuniting with the Jedi Order in hiding. For example, in one fanfiction he teams up with other surviving Jedi to undermine the Sith's new regime.
In such fanfiction, it could lead to a completely different power dynamic in the galaxy. Maybe the Jedi would regain their prominence and prevent the rise of the Empire.
He could potentially team up with other Jedi survivors and go on a mission to find and protect Force - sensitive children from the clutches of the Empire. This would be his way of rebuilding the Jedi Order in secret.
Well, a common plotline is Mace Windu joining the Rebel Alliance in a covert way. He uses his Jedi skills to help the Rebels without revealing his identity at first. Also, there are stories where he travels the galaxy to find other Force - sensitive beings and forms a new group that opposes the Sith - dominated Empire. These plotlines are popular because they give Mace Windu a chance to be a hero in a different way than he was as a regular Jedi. He has to be more cunning and resourceful in these scenarios.
Mace Windu was a powerful Jedi Master. He was known for his purple lightsaber and his skills in combat. He was a member of the Jedi Council. He played a significant role in the Clone Wars, leading the Jedi in many battles against the Separatist forces. He was also involved in the discovery of the Sith Lord Palpatine's true identity, which ultimately led to his confrontation with Palpatine in the Chancellor's office.
Maybe Mace Windu travels to a time long before the Sith rule and learns ancient Jedi techniques that he then brings back to his own time. This could change the power dynamic between the Jedi and Sith in his era. He might learn how to better resist the dark side temptations that the Sith use against the Jedi.
Well, it could focus on Mace Windu's early days in the Jedi Order. Maybe show how he was trained, his first encounters with the dark side threats, and his rise within the Order.
One of the most memorable moments was when he faced Palpatine. His purple lightsaber clashing with Palpatine's in that intense duel was epic. Another moment was his leadership during battles in the Clone Wars, where he showed great strategic acumen.
If Mace Windu didn't die, he might have trained more Jedi and prevented some of the Order's downfalls. His presence could have altered many events in the galaxy.
