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.
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.
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.
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.
I'm not sure exactly as I haven't read it in detail. But it likely focuses on the adventures and stories related to Mace Windu. It might include his battles, his relationships with other Jedi, and his role in the Star Wars universe.
Mace Windu was a powerful Jedi Master. He was known for his purple lightsaber, which was quite unique among the Jedi. He was highly skilled in lightsaber combat and was a respected member of the Jedi Council. He played important roles in many galactic events and conflicts, often being a key figure in the fight against the dark side.
The plot could also involve a power struggle of sorts. Anakin, being a powerful Force user, might initially resist Mace Windu's training methods. This could create tension between them as Mace tries to mold Anakin into a more Jedi - like figure. Meanwhile, other Jedi might be watching this relationship closely, either in support or in suspicion, which could add a layer of political intrigue to the fanfiction.
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.
Padmé Amidala could also be a part of it. Since she has a strong relationship with Anakin, she might notice the changes in him due to the training. She could either support or be worried about the new Anakin that is emerging under Mace Windu's tutelage. Additionally, some of the other Jedi Council members like Plo Koon or Ki - Adi - Mundi could be involved, perhaps observing Anakin's progress and having their own opinions on it.
