Imagine Mace Windu was on a secret mission before his supposed death. The mission led him to be cut off from the Jedi Order. He resurfaces during Star Wars Rebels. He could bring with him ancient Jedi knowledge and artifacts. He could share this knowledge with the young Jedi in the Rebellion, helping them to better understand their powers and the history of the Jedi.
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.
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.
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.
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.
Another possibility is rogue Jedi who have turned to the dark side. They could be former comrades of Mace Windu, and he has to face them in combat. This would add an emotional layer to the story as he has to fight people he once considered friends and allies.
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.
Anakin could be part of a time - travel story in a fanfiction. What if a character from Star Wars Rebels was sent back in time and met Anakin before his fall? They could try to change the course of his future, which would have a huge impact on the events of Star Wars Rebels and the entire galaxy.
Palpatine could still be the main antagonist. Even if Mace Windu travels through time, Palpatine's long - term plans for galactic domination would still be a major threat. Windu would have to find new ways to outwit him in different time periods.
One way is through flashbacks. Maybe Kanan or Hera have heard stories from older Jedi about Yoda. These stories could then be shown in flashbacks and influence their actions in the present. Also, Yoda's teachings could be passed down through Jedi texts that the Rebels find. This would be a more indirect but still realistic way of incorporating him into the story. And his connection to the Force could be felt by Force - sensitive Rebels in times of great need, guiding them without actually appearing physically.
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.
