A couple of supporting characters perish in the story. However, Han Solo manages to navigate through the challenges without dying. The deaths serve to heighten the stakes and drive the narrative forward.
If Ahsoka dies in fanfiction, it would have a huge impact on her friends. Anakin, for example, would be deeply affected. He already lost his mother and has a fear of losing those close to him. Her death could potentially drive him further towards the dark side as he grapples with grief and anger. Her presence has always been a positive influence on him, and without her, he might lose some of his moral compass.
In many fanfictions where Ezra dies, it often serves as a very tragic turn of events. Some fanfictions might have him sacrifice himself heroically, perhaps to save his friends or to stop a great evil. This can add a deep sense of pathos to the story, making the remaining characters deal with the loss in different ways. For example, Kanan might be deeply affected, as he was like a mentor to Ezra.
If Anakin dies, it would likely change the course of the Clone Wars significantly. The Jedi would lose one of their most powerful warriors. His death could lead to a morale decline among the Jedi and their allies.
The other characters would be greatly affected. Her death could shatter the Rebel Alliance's morale. Leia was a symbol of hope and leadership. Without her, there could be internal power struggles. Some might try to fill her shoes but fail, leading to chaos. It could also change the way the galaxy views the fight against the Empire. Her diplomatic skills were important, and without her, the Alliance might struggle to form new alliances or keep the ones they have.
It would have a huge emotional impact on Anakin. His fall to the Dark Side might be even more rapid and extreme. Without Padme, he has no reason to hold on to his remaining light. This could lead to more chaos in the galaxy as he becomes a more powerful and unrestrained Vader.
Another scenario could be that Anakin is mortally wounded during a mission. Maybe he gets caught in a trap set by the Separatists. His death could then lead to a great shift in the Clone Wars, with his comrades having to deal with the loss and the consequences for the war effort. For example, Obi - Wan might be deeply affected and it could change his approach to the war.
One common theme is sacrifice. Ezra might die to save the rebellion or his friends. Another theme could be the impact of his death on the other characters. For instance, how does Sabine deal with the loss of her close friend? Also, there could be themes related to the Force. Maybe his death causes some sort of disturbance in the Force that has unforeseen consequences.
It depends on which specific versions you're referring to. The runtime of Star Wars Episode III: Revenge of the Sith is around 2 hours and 20 minutes. As for the Star Wars story, it's not clear which one you mean, as there are various spin-offs and standalone tales with different lengths.
If Anakin dies while saving his family in a fanfic, it could have a huge impact on the Star Wars universe. For one, Luke and Leia might grow up without any knowledge of their father, or with only the heroic version of his sacrifice. The Jedi Order might be seen in a different light, as Anakin's death could be seen as a noble end to his struggle with the dark side. It could also change the relationship between the Empire and the Rebellion, as there would be no Darth Vader to be a central figure in the Empire's tyranny.
