Well, if Mace Windu killed Palpatine, it might have changed the course of events drastically. The Sith's plans could have been foiled, and the Republic might have been saved from falling into darkness. But it also could have sparked new conflicts among the Jedi themselves.
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.
The galaxy would have been in chaos. The balance of power would shift dramatically, and there would likely be power struggles among the Jedi and other factions.
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.
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.
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.
It could have completely changed the course of the Star Wars universe. With Palpatine out of the picture, the Sith might have crumbled and the Jedi could have regained their influence.
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.
One similarity could be the loyalty aspect. Mace Windu is loyal to the Jedi Order and its principles. In Pulp Fiction, Vincent Vega is loyal to his boss Marsellus Wallace to a certain extent. Also, the action scenes in both are quite iconic. Mace Windu has some amazing lightsaber battles in Star Wars. In Pulp Fiction, the fight scenes, like the one in the pawnshop, are very memorable. But overall, they are from very different cinematic universes, so the differences far outweigh the similarities.
It would likely have led to a very different outcome for the Star Wars universe. Maybe peace would have been restored earlier.
