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 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.
Perhaps there's a prophecy involved. The fanfic could be set up where it's foretold that Boruto will bring about a great change, but only if he survives a certain threat. Naruto, aware of this, sacrifices himself to ensure Boruto lives on. This could then trigger a series of events where Boruto has to deal with the political fallout in the village, as some may blame him for Naruto's death, while others see him as the key to the future. It could also lead to a rift between Boruto and some of his friends who struggle to understand why Naruto had to die for him.
A possible plot twist might be that the force behind the marriage is actually an ancient evil that wants to use their union to gain power. Artemis and Percy then have to team up to not only deal with the unwanted marriage but also defeat this evil. It could also be that Artemis has a way to break the forced marriage bond, but in doing so, she would lose her immortality, which adds a huge moral dilemma to the story.
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.
A plot could involve Percy being cursed and the only way to break the curse is to sing a song that moves Artemis. He has to learn about her past, her values, and her likes in order to create the perfect song. Or perhaps Percy discovers a new power within himself - the power of song - and he decides to test it out on Artemis, not knowing how she will react. This could lead to a series of adventures as he tries to make amends if she is initially offended.
One possible plot twist could be that the gods interfere to stop the marriage at the last minute. They might realize that such a union goes against the natural order. Another could be that Percy discovers a way to break the forced bond by finding a magical artifact. Or perhaps Artemis herself finds a loophole in the situation that allows her to avoid the marriage without causing chaos among the gods.
One possible plot twist could be that Artemis's blindfold is actually a self - imposed thing to gain a new power, and Percy discovers this secret halfway through the story. This would completely change their dynamic as Percy realizes he may not have been needed as much as he thought.
One common plot twist could be Percy discovering that his connection to Artemis brings some unforeseen powers. For example, he might gain the ability to communicate with certain animals that are sacred to Artemis. Another could be that there's a prophecy about him that was hidden until a crucial moment, changing the course of his journey. Or perhaps he finds out that his parentage is more complex than he thought, with some dark secret related to Artemis that others have been hiding.
