The plot might involve Percy's journey to becoming the king of the void. He could start by accidentally stumbling into the void. There, he discovers that there's a power struggle going on. With his friends' help, or maybe on his own, he has to prove himself worthy of being the king. He might have to face challenges like taming wild and otherworldly beasts, or solving ancient riddles that are the key to ruling the void.
The plot could involve Percy being the only one who can stop an evil force emerging from the void. Since he is the 'God of the Void' in this fanfiction, he has unique abilities that no other demigod has. He might have to journey into the heart of the void, which is a place full of strange and dark energies, and face his greatest fears along the way.
Well, one possible plot could be that Percy, as the reincarnation of void, has strange new powers. Maybe he can manipulate emptiness or darkness in a way that both helps and scares his friends. For example, he could use it to create barriers of nothingness that enemies can't cross. But at the same time, he has to struggle with not being consumed by the void within him.
Obviously, Percy Jackson himself. And probably his friends like Annabeth. There might also be new characters unique to the void, like strange creatures or spirits that inhabit that place.
One possible plot could be Percy Jackson having to navigate the complex politics of Rome as the King. He might face challenges from rival factions within the Roman demigod community who don't want an outsider like him in power. He could also be tasked with protecting Rome from new and powerful monsters that are specifically targeting the city because of his rule.
One possible plot could be Percy Jackson having to face new challenges after becoming the King of the Titans. Maybe he has to deal with the other gods who are jealous or afraid of his new power. He might also try to reform the Titan realm, making it less about domination and more about harmony.
Well, one possible plot could be Percy using his water - controlling abilities in the world of Alagaesia. Maybe he teams up with the local heroes there and they face some common enemy. For example, a powerful dragon that is threatening both the demigods' world and Alagaesia. He could also introduce new combat styles to the people of Alagaesia based on his training at Camp Half - Blood.
One possible plot could be Percy discovers he has a special connection to the Hellhounds. Maybe he is able to communicate with them in a way no one else can. He then has to use this ability to solve a mystery in the demigod world. For example, some important items have been stolen and the Hellhounds know where they are, but they will only tell Percy.
Well, it could be about Percy using his demigod powers in the unique Alaskan setting. Maybe he has to deal with local mythological creatures that are specific to Alaska and assert his rule as the 'King of Alaska'. He might form alliances with native Alaskan demigods or spirits.
Well, perhaps in the fanfiction, Percy is summoned by the 'King under the Mountain' because of his reputation. The king wants Percy to retrieve a powerful and ancient artifact that was lost in a dangerous part of the mountain. Percy teams up with some of the king's bravest warriors. Along the way, they face all sorts of mythical creatures like trolls and goblins. Percy has to use his wits as well as his powers to overcome the obstacles and claim the artifact.
No, it's not a common opinion. The Percy Jackson fandom is quite large and diverse, and while there may be some fanfictions that are not well - done, there are also many excellent ones. Fans often create fanfictions to expand on the world, fill in gaps in the story, or explore different relationships. So to say that all Percy Jackson fanfiction is 'void' is a very broad and inaccurate generalization.
