If Percy kills Tartarus in the fanfic, it could completely rewrite the mythology of the series. The other gods and goddesses might react in different ways, some with fear of Percy's new - found power, some with envy. It could also inspire other demigods to be more aggressive in dealing with threats, thinking that if Percy could kill Tartarus, they could take on other big enemies. This would lead to a more chaotic and perhaps darker turn in the overall narrative.
It would likely be a huge shift. In the original series, Tartarus was a major and almost unbeatable force. If Percy kills him, it would change the power balance completely. Other characters might view Percy as more of a god - like figure, which could lead to new relationships and conflicts.
Well, it completely flips the dynamic. In the original series, Snape was a complex character with a lot of hidden motives that were ultimately revealed to be on the side of good. If Harry kills Snape in the fanfic, it makes Harry seem more impulsive and less of the heroic figure we know. It also undermines the redemption arc that Snape had in the original story.
Perhaps Percy had lost someone very dear to him because of Tartarus. This could have filled him with so much rage and a thirst for revenge that he decided to kill Tartarus. In fanfics, emotions often drive characters to extreme actions. Percy, being a hero, might have thought that taking out Tartarus was the ultimate way to avenge the wrongs done to him and those he cared about.
The 'Snape kills Harry' fanfiction would shatter the relationships that were built in the original series. For example, the friendship between Harry, Ron, and Hermione would be left in tatters. Hermione and Ron would be devastated and likely seek revenge. Also, Dumbledore's plan, whatever it was that involved Harry, would be completely ruined. The whole balance of good and evil in the wizarding world would be thrown into chaos.
For Annabeth, it would be a huge shock. She would likely be torn between her loyalty to Percy and her friendship with Thalia. It might make her question everything she thought she knew about Percy. With Grover, he would be deeply disappointed in Percy. Their friendship would be severely strained as Grover is a peaceful being and the act of killing a friend like Thalia would go against Grover's values.
The power structure would be completely disrupted. There would be no more divine interference in mortal affairs, which could lead to chaos at first as there are no gods to control natural elements like the sea or the sky. But it could also lead to new opportunities for mortals to take control of their own destinies.
The morale among the demigods would be greatly affected. The Hunt is often seen as a symbol of strength and unity for female demigods. If Percy kills them, it might create a divide between male and female demigods, leading to internal conflicts within the demigod community. Also, it would change the way demigods view Percy. Some might see him as a hero for eliminating a potential threat, while others would see him as a murderer for killing the Hunt.
Well, it would create a huge power vacuum. Ares was one of the major gods, and his death would surely shake up the balance of power among the gods. Other gods might start jockeying for his territory or influence.
The story would take a very dark turn. Percy is a central figure, and his death would leave a huge void. His friends would be devastated. Annabeth, for instance, would likely be consumed with grief and seek revenge. This could lead to a new conflict within the demigod community.
In the long run, the absence of Naruto would mean the loss of his positive influence. He was a symbol of hope and unity. Without him, the ninja world might fall into more despair and division. The new generation that looked up to Naruto would be left without their role model, and the future of the ninja world would be much darker.
Well, it completely flips the story on its head. Dumbledore is a central and positive figure in the original. His death is a major turning point, but for Draco to kill him for Hermione means Draco's character has a huge shift. It also makes Hermione a much more central and controversial figure, as her presence has now caused such a drastic event. The relationships between the main characters like Harry, Ron and Hermione would be severely strained as they deal with this new and unexpected development.
