One common theme could be Percy feeling betrayed. For example, if other demigods don't believe him about a new threat. Another might be his anger towards the gods for not fulfilling their promises. He could be angry at Zeus for not protecting his friends during a battle. Also, it could involve Percy being angry about how demigods are treated in general, like being used as pawns in the gods' games.
If the gods were to interfere with her plans for the hunters without her consent. Artemis is very protective of her hunters and their way of life. Any meddling from the other gods in her domain could easily enrage her in a fanfiction scenario.
The gods would be involved. Zeus, Poseidon, or any of the other gods. If they make decisions that affect Percy negatively, like sending him on a dangerous mission without proper support, he'd be angry. Also, Clarisse could be in these stories. She and Percy have had their share of conflicts in the original series, and in a fanfic, she could do something to really tick Percy off, like stealing his thunder (figuratively speaking) in a battle or competition.
There might be a fanfiction where Artemis is angry because of some false rumors spread about the Hunters. She could be on a rampage to find the source of these rumors and in the process cross paths with Percy. Maybe Percy gets caught in the middle and has to help her clear the Hunters' name while dealing with her anger.
No. Percy Jackson is an original fictional series. Although it uses Greek mythology as its base, it has created a completely new world, characters, and storylines. Fanfiction usually implies building upon an existing work in a more derivative way, often by fans rather than the original creator. 'Percy Jackson' was created by Rick Riordan as an original concept.
In Percy Jackson fanfiction, families can be depicted in various ways. Some might show Percy's family having new and unexpected adventures together. For example, his mom could discover a new magical ability that she uses to protect the family from an ancient threat. Another idea could be that Percy's half - brother Tyson becomes a key figure in protecting the family from monsters that target them specifically because of Percy's fame among the demigods.
One idea for a Percy Jackson famous singer fanfiction could be that a famous singer is actually a demigod in disguise. Maybe they use their music as a form of magic or to communicate with other demigods secretly. For example, their lyrics could hold hidden messages about upcoming quests or threats to the demigod community.
One possible reason could be jealousy. Maybe Jackson has something Stiles wants, like popularity or a girl he likes. For example, if they both like Lydia, Stiles might get angry at Jackson's smooth ways with her.
Well, in some fanfictions, it might be related to his demigod powers. Since he has a connection to the water element, blood being a liquid could potentially be manipulated in a way similar to how he controls water. Maybe he can sense the water content in blood and use his will to move or influence it.
