A possible plot twist in a 'Percy Dies Saving Artemis' fanfic could be that his death was not in vain, but rather a strategic move by some greater power. Maybe the Fates had planned it so that his death would create a distraction for an even greater evil that was about to be unleashed. Artemis, in her grief, could then discover this truth and be the one to take on this new threat with a new - found determination. Additionally, Percy's death could cause a shift in the balance of power among the demigods. With Percy gone, other demigods might step up in unexpected ways, and this could also play into the overall story as Artemis tries to navigate the new power dynamics in the demigod world.
The other demigods would be devastated. Percy was like a leader to many of them. Annabeth, his girlfriend, would be heartbroken. She might go on a quest for revenge against whatever or whoever put Percy in the situation where he had to sacrifice himself. The campers at Camp Half - Blood would also be in mourning. They would probably hold a big memorial for Percy. His friends like Grover would be in shock and would feel a great sense of loss.
Well, for starters, Artemis would probably be in shock. She's a goddess, not used to being saved in such a drastic way. She might become more protective of the demigods as a result. As for Percy's friends, they'd be angry too. Angry at the situation that led to his death. They might question why Percy had to be the one to sacrifice himself. And the younger demigods would look at Percy's death as a very solemn event, a reminder of the risks they all face. It would be a very dark time in the demigod community.
Percy's death would shatter the world of those who knew him. His friends like Tyson would be inconsolable. Tyson always saw Percy as a hero and a brother. The Hunters of Artemis might also be affected. They would respect Percy's sacrifice but also feel a sense of responsibility for his death. And the gods, who had often used Percy for their own ends, might start to question their actions. Some might feel remorse, while others might fear the chaos that could follow in the wake of Percy's death, as he was often a stabilising force in the often - tumultuous world of demigods and gods.
It could start with Artemis getting into a situation where she's in a vulnerable position. Maybe she's been lured into a place where her powers are diminished. Percy, being a friend and an ally, rushes to her aid. Along the way, he has to fight through hordes of lesser monsters, which takes a toll on him. When he finally reaches Artemis, they are confronted by a really powerful adversary. Percy realizes that the only way to save Artemis is to take the full brunt of the enemy's attack himself. So he does, and that's how he dies.
Percy's death would be a major turning point. In the demigod world, it could mean a change in alliances. Those who were allied with Percy might seek new partnerships. The balance of power among the different camps of demigods would shift. His death could also inspire a new generation of demigods. They'd hear the story of his sacrifice and be motivated to be as brave. However, it could also lead to a period of chaos as the demigod world adjusts to the loss of such a prominent figure. Artemis might play a role in trying to restore order, but it wouldn't be easy as the demigod world reels from Percy's death.
In this fanfiction, Percy might sacrifice himself in a grand battle. He could be facing a powerful enemy that was about to strike Zoe. Percy, being the heroic type, jumps in front of Zoe at the last moment. His last thoughts could be of his friends and all the adventures he had. Zoe, in turn, is left with a deep sense of guilt and sorrow, vowing to carry on Percy's legacy. She might become even more determined to fight for the cause they both believed in, all while mourning the loss of her dear friend.
In this kind of fanfiction, it's often a very tragic and heroic concept. Percy sacrificing himself to save the seven would be a huge shock to the other characters. It might lead to a lot of grief and also a new sense of purpose for the remaining seven. They would have to carry on with their mission while also dealing with the loss of Percy, which could add a lot of depth to their character development.
In this fanfiction, it could be that Artemis is in a situation where she is about to be killed or lose her powers forever. Percy, being the selfless hero he is, takes on a deadly task to prevent that from happening. Maybe it involves facing an ancient and malevolent god who has a vendetta against Artemis, and Percy uses his unique abilities and the element of surprise to try and stop this god, but at the cost of his own life.
Perhaps a powerful and corrupted demigod could be the main antagonist. This demigod might be jealous of Artemis' power and popularity among the other demigods. He devises a plan to harm her, and Percy, being loyal to Artemis, has to give his life to save her from this rogue demigod.
